Is Techron better than Seafoam? Let's see the proof! 

The hours and hours and hours that this guys puts into each video is crazy. Respect.

Man this amount of quality work should be on paid channel. Thank you very much sir, for putting so much effort and time into these informative videos. Straight facts, true unbiased info., unlike you get from a tv ad or neighbor, friend, dad, etc.

When I worked for Nissan, we used a fuel injection cleaner made by 3M, you bypass the fuel rail and run the engine right off the pressurized can. worked great ! especially on the carbon magnet VG30 engines. When I asked the parts rep what was in the 3M cleaner ? he said it's 100% techron. Been using it ever since. Except I put in two bottles per tank about every 4-5th fill up. When I traded in my 2006 Kia Spectra three years ago, it had 354,000 on it and never burned any oil. Great stuff !

I love going back in the PF archives. Would love to see a new update on this, or more around fuel injector cleaners. Checking compression before and after see how they perform.

You are one of the best youtubers. Seriously.

I love how thorough this guy is in everything

This guy truly does an amazing service to all of the handy man and he doesn’t take anything from any company to test. We all appreciate everything you do for us . Keep up the great ideas in tests you make for each item. Btw I loved watching you make a homemade knife that was really awesome.

Thats a pretty ambitious test. A lot of time went into that video. I appreciate it

Your comparison videos are in a class of their own! Excellent! Don’t stop!

An excellent video - thanks. I use Seafoam in the fuel, a little at each tank refill, with all my lawn mowers, trimmers, power saw, etc. 2 and 4 cycle for years now and absolutely no "bad gas" problems. Everything fires up in the spring with no gas issues whatsoever. Additionally, I rarely change spark plugs anymore, only every 5-6 years and honestly they always look just fine. I've never used it in my cars, just the small engines. I agree, any additive is probably better than nothing.

I like Techron. I fill up with Chevron gasoline which already contains Techron, as preventive maintenance. My mechanic recommended it. It runs good and passes the emissions test every time. I add a bottle to a tankful once in a while but otherwise no additives. I run 87 octane and consider the slightly additional cost of the Chevron an investment and so far it's paid off. Not that I wouldn't use other top brands or try Seafoam but the Chevron with Techron is working for me. Great video, as always!

I really appreciate that you did it over and over to make sure we get the perfect idea of these products. Thank you for your efforts and your time.

Dude your dedication to testing these products makes your channel unique in its own way. So glad I found you and I appreciate all the time and effort you put into making these videos/tests. Probably my favorite RU-vid channel, and I watch a lot of RU-vid lol

Really respect and appreciate the amount of time and effort you put into making all that - it was fascinating! I was curious about these products so it's really interesting to see the comparisons. I live in Thailand and run a Mitsubishi Attrage which is designed to run on E20 (a mix of 20% ethanol 80% gasoline) as are most cars over here. I've never opened up the engine (obviously) so I've no idea if these cleaners work and really appreciate seeing the results on your lawnmower. I've always used the official Mitsubishi fuel system cleaner, but I recently saw the the E20 fuel I buy actually contains additives (or something) designed to keep the engine clean, like the fuel nozzle unclogged.

I have used Techtron for years after it corrected a stalling problem on a 1999 Mercury V6. I use it twice a year and also try to use only Shell gas. Interesting video. Thanks. OleDave

I loved the way you used Fast Forward to save us all a lot of time - nice job !!

Cannot say enough good things about the quality of your videos and your testing. This is tremendously helpful for me, and for my customers at my automotive shop. Keep up the great work!

Yes, I appreciate hearing your opinion after the video. This is great. Seems like you'd do best using all three of them at the same time! Or back to back to get the ultimate clean. I don't use cleaners but might give them a try.

I was an automechanic for 30+ years and one product we sold at a few of the shops I was employed at was BG aka Bearing and Gear. We did top engine cleaning with it and also installed a pressurized system that cleaned the injectors and rails. Note you had to pull the fuse or relay for the fuel pump to do it and on return type system block it off. This was done with their injection cleaning rig and was somewhat involved but honestly did a great job. Customer always noticed a huge difference on vehicles with over 70K on them. Would mind see you try the BG fuel system cleaner...

I would like a spark plug and head gasket for my mower please Parts guys: How many? 500 of each please

Hey man I love how thorough and well thought out your tests are. Keeps me coming back. Thanks for all the effort for them all!

Another great video. I have used sea foam in the past and it looks like sea foam performed the best visually. We are trying to get a outboard motor working and will be adding sea foam to the fuel. Thanks again. I like how you test and show us results on video. All the best!

The patients on this guy is truly amazing.... RESPECT for doing all these projects..

You put so much work, thought and effort into these videos. I think a lot of us value your opinion on the products, and believe your opinion, or we could say final thought, would be a great addition and widely accepted from everyone. Also I am so happy with the speed that your channel is growing. Been here since about 70k, and how time flies to almost 200k! Keep up the great work.

As an OEM automotive engineer, I worked for many years with colleagues at Chevron and Techron is a very good product. I don't know about the formulation today but it used to be a chemical called poly butyl ether amine. This is an expensive additive to manufacture but highly effective. I have used it in my own vehicle by (1) filling the tank and then (2) adding one full bottle of Techron. In the past, I have done this on two consecutive tankfuls and it makes a difference. One has to be careful not to overdose the fuel with additives because this can potentially thicken the motor oil and cause issues like valve sticking. Modern fuel injectors are very resistant to plugging/reduced flow and most ordinary gasolines have additives sufficient for adequate cleaning. Fuel injection cleaning at a service appointment is not needed and a complete waste of money. Techron helps keep intake valve and combustion chamber deposits at bay - these can cause cold driveability issues and increased emissions. There are a number of good SAE papers on this topic. Currently I just use Amoco/BP Ultimate gasoline. The base fuel is refined using a proprietary process removing impurities and it has a very good additive package for cleanliness. It is the best gasoline and engines run exclusively on this are spotlessly clean internally even after 70-80,000 miles. It is expensive but one gets what he pays for. Good video and test methodology. Thank You! 🙂👍

I have run seafoam since I was a teenager. If you want to see a lot ALOT of proof it works try it on a higher performance engine. I ran it thru an old motorcycle, an FZ600, it made the engine run like NEW. I am also a big fan of engine Restore. Tried it on my wife’s mini cooper with 130k on it, like a new car I swear

Your testing is always phenomenal. I've recently considered using Techron but now may have to reconsider

Honestly this is my favorite RU-vid channel. Thanks PF for being so unbiased and helpful

By far, the most impressive additive I've ever used was "Yamaha Ring Free" on two stroke Yamaha outboards. It was absolutely amazing. Research seemed to indicate that it was developed by the same people who came up with Techron using the same ingredients. Thanks for taking time to do this video.

I just found this video and would like to comment on my experience with Techron. I started using it over 30 years ago when it cleared up some dirty fuel injectors in a 1978 Audi Fox. I have used it on all my car, motorcycle, and lawnmowers since and have had zero fuel system problems. Injectors and carburetors stay clean. I will run *two* tankfulls through each vehicle just before a scheduled oil change at the recommended dosage on the bottle of 1 oz per gallon of gas. On two motorcycles - each with about 60,000 miles - given that they have only a 5 gallon tank whereas the cars are 15 to 20 gallons, I ran 5 tanks of Techron one time and noticed a significant increase in performance and running smoothness. I've seen dirty carburetor bowels on motorcycles cleaned up perfectly after 5 to 10 gallons (again, at 1 oz. per gallon). I do believe their claims of cleaning and engine in one tank are optimistic, but by using Chevron fuel and the treatment schedule I've described, my engines and fuel systems have stayed very clean. It was good to see in your test that both Seafoam and Marvel Mystery Oil also will provide good engine cleaning.

I am a gas tanker driver for 25 years now. When I did Chevron stations in a Chevron takeover from another brand, Conoco or whomever, we would add raw techron into the tanks. 1 quart would treat 3000 gallons of gasoline. When Chevron change the techron formula they gave the older formula to the driver's to use. A quart bottle would last me years. Anded my own to each tank. Had a chemist do the math for how much to add to 20 gallons of gas, then I doubled it. I changed heads on my car for better performance and was shocked at how clean the valves, pistons and chambers were. I rebuild the Edelbrock carburetor and it really was clean... I'm down to my last quart now..🥲

You must have the shortest grass lawn in the neighborhood.

You make great videos Project Farm! I've probably watched 20 of them now just out of interest, but this was the first one I actually sought out for advice on a specific topic, and I couldn't have been happier with your methodical approach to these tests. Thank you for doing this work. It is obviously very time consuming and very well thought out, and I know I'm not the only one who benefits from your efforts!

I had a client share this video, great channel! My experience was similar to years when testing on RV generators. My recommendation has been to alternate between Seafoam and Techron to try and get the best benefits of both as they do seem to work better in different areas of the engine.

Ty! I love these videos and the quest for knowledge on this subject. Thank you once again and always look forward to more!

Your efforts here are very much appreciated! Thanks for doing this for us.

Thanks for taking the time out to actually put these products to the test it helps us viewers determine what's good and what's not I was just watching another Channel and this guy was rambling about something but never took the time to actually put it to work and you actually work hard on your channel and do things the right way thank you very appreciative

Really appreciate your efforts. I’m surprised why your video was in way down when I searched for the related video. Your video was the best 👍

I used Marvel Mystery Oil as an additive to 87 octane aircraft fuel. The engine was a Lycoming 4 cylinder O-320 with high hours (1000 hours past recommended overhaul of 2000 hours). I could feel the difference after just one tank. I continued to use MMO in the gas and oil and the engine snapped back to running smooth and powerful. It started quickly and the throttle response was smooth. MMO was developed by the same guys who made the Marvel-Scheibler carburetor for light aircraft engines. It might be a mystery but I can say for sure it works well.

I've seen techron clean out stuck fuel injectors in just a few dozen miles. It works at least with regards to injectors. I put a bottle in all my vehicles gas tank whenever I do oil changes.

Wow. When I heard you say you were gonna run each one through 1 tank of gas I thought there was no way that would be a long enough test to put each one through its paces. After seeing the results, it's crazy to see that much carbon build up on just 1 tank of gas.

Always enjoy your very thorough evaluations of products; expertly done and easy to understand. Would like to see you run a test on Amsoil Performance Improver fuel additive. Thanks!

Thank you for being thorough with your testing. I've been using Chevron gas with techron already included since 1985 and never has issues with carburetors nor fuel injections. Mainly had Nissans and Toyota. First car was a Honda. Only had to change mechanical fuel pump once on 81 Celica at 140,000 miles. No other fuel pump. Great videos you produce.

Very solid test plus I love the control run! Great content keep it up!

Love it. I am a huge believer in seafoam pretty much forever. The techron didn't seem to do much. I really enjoy this channel. Thanks again. You rock!

Seafoam has worked for me for years. Mild solvent that is safe for engine and fuel system. Excellent for periodic maintenance especially in this era of turbochargers. Nice video as always brother.

its amazing how much carbon buildup comes from just one tank of fuel, could do a test on different gas to see which gas burns cleanest?

Interesting test! I have been using Techron since 1984 starting with a 1983 Isuzu Impulse which required mid grade fuel in order to run. After several tanks it would develop an annoying hesitation. The addition of Techron would resolve this problem. I have seen Techron solve many fuel related problems in a wide variety of engine since then and always keep some on hand and use it as a periodic additive. My view, great stuff!

I really enjoy your videos and appreciate your time and hard work you put into your channel. Thank you! Please do an updated testing and conduct them using a vehicle. Seafoam, CRC, Lucas, etc.

I use BG 44K in all my vehicles and small engines to clean out the fuel systems. I also flush all my engines with BG's EPR. I have flushed my engine with Gunk auto flush, then put a new filter and 5 new quarts of oil. The oil always comes out darker the second flush with the BG's EPR. I go with the recomended time of 10 minutes with the Gunk, and 30 minutes with EPR, because they recomend 10 minute minumim run time. I also add prolong engine addive and BG's RF7 to every oil change. I spend around $100 per oil change on each of my 2 vehicles. I put 2 oz of prolong, and 1.5 oz of RF7 in my (7) small engines. I only use Star Tron Enzyme fuel treatment to gas. It is keeps fuel stable for 2 years. I really enjoy watching your videos. Keep up the great work, and a big Thank You for your hard work!!!

Your attention to detail is impressive. Consumer R should pay you to do testings. Thanks - love watching the tests

I'm surprised about the Techron. I'm a GM mechanic since 2000. Years ago we had several problems with fuel causing issues in South Texas. GM came up with a process to put their chemical "Top Engine Cleaner" in a measured amount of gas and flush it directly through the fuel injectors w/ the feed and return lines disconnected and blocked. You would then add a bottle of Techron to the tank. As mechanics working on flat rate, the " unofficial" repair was to mix the Techron and Top engine cleaner 50/50 and force that through the injectors. It was magical! I've had several Trailblazer injectors that would not flow any fuel at all return to a near new level of flow. I also personally used one bottle of Techron with 5 gallons of gas to clean up motorcycle carbs. You had to run a fresh gas tank after as it would eat important stuff at that concentration. With great success I bought motorcycles that would barely run, ran that mixture for a tank or two, and then sold them when I was done having fun with them. I even had a case where that mixture cleaned things up so we'll a Kawasaki intake valve hung open a little. I'm guessing from lack of fuel lubrication. Pulled it all apart and everything was so shiny and new it looked like it had no miles on it. Back together and she ran like new and still does as far as I know. I'm aware that our mixture was well above any recommendations. I'm also aware that when you pay mechanics Flat Rate they will do almost anything to make a problem go away and stay gone. Really like your videos, Thanks!

I’d like to see the amsoil PI fuel additive in a test like this. Great work! As mentioned many times, the amount of work you put into these videos is much appreciated! Thanks for all your efforts and outstanding content.

Imagine if you have a company in the future that test products, and investors and consumers rely on your results. that would be amazing

This is the first place I go when I’m evaluating a product. I trust you completely so ABSOLUTELY express your opinion on what you think of the product you are testing. “Being trusted is way more important then being loved”. It’s nice to have a place to go I know that there is no hidden agenda‘s.

In my corvette I used Techron mainly to keep the Fuel pump and and fuel gauge sender (in the left tank) working. Recommended by Vette owners and it worked for me.

If I'm buying anything for the workshop I always check to see PF has a video on it. Unfortunately not all items are available in the UK but at least I know what to expect from those that are. Extremely rare to see such honest, impartial and practical testing these days.

Outstanding work. I always learn something from you, and I truly appreciate that. Merry Christmas to you and your family.

Agree on additives i think i’ll start using one. Techron. THANKS for sharing this very informative video!!!

Thank You!! It's obvious, how much time was invested to get this information to us. God Bless

Love your videos, you're very thorough in your methods. I send links to my friends, hopefully they are watching you as well. How about a test of synthetic oil filters for motorcycles?

Shell claims to clean 60-70% of initial carbon deposits on one tank of nitro+ premium fuel. That's a pretty bold claim, definitely higher than any of these additives. You should do a review on all gas company fuels in general, but be sure to include the top end shell fuel to see if it's worth getting it as a engine cleaner. Thanks so much!

Very well done, love how detailed your carried test out

Your mechanical scientific experiments are quite educational and enjoyable. Thanks for doing this. Great public service tool for consumers.

I used to use Techron on every third fill up on my 96 geo with 260000mi and stopped that with having a couple newer cars but will start again with my newly aquired 99 ranger with 118000mi. As your usual great, helpful content, thank you

Very impressive! The work you put in on these videos is so useful. Thank you for your contribution to our knowledge base!

I love hearing your personal assessments of the product tests you do. Please keep them coming.

Thank you for the in depth tests!! Not just a basic run thru but replaced spark plugs & gaskets and cleaned surfaces to give a true base level to compare to!! Top notch

Wow ! This is pretty awesome. I need to add it to my motors. Thank you, fornthe help and information. Please keep it coming. love your videos. Really helped.

Use Seafoam on my 175 hp outboard….. anytime I have stuttering or hesitation in performance it has always helped with carbon buildup. Haven’t tried others but sticking with what I know works!

Just joined your Patreon. You and your testing are so invaluable. Love your channel! ❤️

Take engine apart and clean cylinders after each fill up. Got it.

I've used tech. When I go on ongoing trips in my f-250 5.4 2003 and Chevy 1500 5.3 2002 both 4x4s. I've noticed better fuel economy by 2 to 3 mpg. Before ethanol as much as 5 mph highway 55 to 65 mph.

Is it possible to actually compare fuel brands like mobil,shell,Costco and such? Would make an interesting test

Great Video and experiment! I would like to have the before and after weights as well to get a quantifiable amount of buildup rather than just a visual comparison

Love this channel. I ran Techron in my 1994 Nissan Sentra every 3k miles and drove the car for 22 years. Never had a fuel system problem and ran the original fuel injectors until the car got towed at 280k miles (it was worth less than the tow fee, so gave them the car.) Original fuel pump lasted 216k miles. My 1995 Nissan truck has seen the same maintenance and has never once had a fuel system issue - I credit Techron and using it every 3k miles over these vehicles’ lives. The truck is in my garage today, starts every single time I turn the key.

I’ve been subbed for years and just decided to buy some techron today. Imagine my surprise when you’ve already made a video on it.

I took a repair class and the mechanic that taught it swore by Techron. I also read an article that put it as #1. What about doing all 3 in succession? Maybe in various orders?

How bout doing some high end synthetic oil test and of course throw them against Walmart's bargain brand to see if they're worth the higher price

thanks again for taking the time to make these awesome videos and letting us see your work man its very neat to see. keep the great vids and inspiration coming.

I used to know a well-known engine builder who confirmed an old trick that had worked for me in the past for un-sticking rings in an old motor; Marvel Mystery Oil, and Mobile 1 motor oil. I would agree on your assessment that one product did better on the pistons and valves, and another did better on deposits on the head, which of course begs the logical consideration; would such "alchemy" help here? Would different combinations keep things spotless? ...or just fog for mosquitoes?

I always enjoy your tests they are excellent & conclusive. I only use (top tier fuels) in my lawnmower & hand held equipment. No problems yet thankfully.

It is so satisfying watching your videos. Who knew that watching a mower sit idling could be so fun! It makes sense that the Seafoam would work where it did since it's made for carbureted engines. But overall I'm disappointed that none of them really "worked" at keeping things clean. Guess we just need to stock up on gaskets and wire brush in between mowings!

I really like your evaluation criteria used in your tests. I have experience with Cfoam and have also used BG 44K. While I've experienced good luck with both it's difficult to tell the difference. Cfoam helped me to start my snow blower and 44K helped my car run smooth during the initial start up. I've not used Techron or Mystery Oil but heard good things about both.

thank you for all the information you provide viewers. I'd be very interested to see how the product "BG 44K" fuel additive compares to some of the additives you've tested. I've used this product in the past with remarkable results. Would be an interesting comparative.

Such an amazing archive of videos if I ever need to see what product to try, there's a video for it!

I think you should do a revised test of this with some of the newer products out there thank you for all your videos.

Love your videos!! My dad has told me to use Techron for years now! Still use it to this day on my Audi.

Am i the only 37 yr old that has never seen someone crank a lawn mower with a drill???🤔

I like this whole line of research and think that there are the following areas of concern: Fuel System Cleaning, Fuel Injector Cleaning, Reducing Carbon Buildup, and finally the potential degradation of rubber Orings for fuel system components. You have done a good job on the general fuel system, but not sure if that applies directly to Fuel Injectors, and if so, then the degradation of the rubber components would be a concern. The focus is for better mileage for small engine cars w/EFI, so if there is a combined set of tests, that might be helpful. Thanks for the great work, Ken.

I use Techron only periodically at the advice of a co-worker who at one time owned a repair shop. He said the engines that he rebuilt where the owner used Techron were far and above much cleaner than the other engines he had worked on. My 1999 Camry with 236K miles seems to like it too!

Love all your content. One thing that may have been overlooked is how well these products clean the back of the intake valve. This is where carbon can get thick and impede airflow into the cylinder. More carbon in the combustion chamber after using a cleaner may indicate that it's working better to remove carbon from the other side of the valve.

I have been a fan of Techron since the late 80s and thank you for your video, this test reflects my experience as well. I still continue using Techron from time to time.

Great video, thanks ! Based on numerous videos touting the benefits of Seafoam, I decided to try it on my 2011 BMW Z4 which was running a little rough. I added it to the gas tank and the oil as directed. The car does seem to run smoother now, but it seems to have possibly cleared up another issue. There is a known defect in several BMWs with PCV valves clogging and emitting a burning plastic smell. BMW is working on a fix for the issue but does not have one yet. Strangely, the burning smell is gone after having used the Seafoam twice. I'm not a mechanic, so I'm wondering if you believe the Seafoam could have resolved the PCV issue or if that was likely a coincidence? The other variable is the weather is warmer now, I was getting the burning smell over the winter when it was colder, not sure if that is a factor ?

With modern engines (catalytic converters) I am skeptical of fuel additives with upper cylinder lubrication additives as they can cause an issue with the catalytic converter. On small engines I use Marvel Mystery Oil but with my Toyota 5th gen 4Runner and other cars/trucks I use Techron with each oil change and have had great results.

I'd like to see something with a higher PEA level, like Gumout Tune-UP or Redline Complete fuel system cleaner. I love your stuff, you really try to follow the scientific method!

I like the video for a number of reasons= It gets to the point and not full of dribble that turns into a 45 minute video---thanks. And, I like the fact that no bias is shown to any one of the products--we can make up our own minds. And I learned that you put the Techron in an almost empty tank then fill up.

Thank you for your service Mr Farm.

I’ve always been partial to seafoam. I run it in my vehicles a couple times a year. Thanks for the video.

Please keep sharing your observations - you can see in person much better than we see in the video so it is important to me to hear your perspective.
