Heet has 99.9 alcohol in it. If using rubbing alcohol, you must find 90% or better . This video was really helpful. Thank you

You did a really nice job with this instruction! Thanks for taking the time to do this...it definitely helped me!

WORKED AFTER LETTING MY TRUCK SIT FOR TWO YEARS! THANK YOU SO MUCH! It is sitting running to kill all what's in the tank still. Keep rocking it with breaks forward and backward every 15 min... still suckin.... thanks so much.

must say this was one of the best simple demo's I have seen. Great job

Excellent Video Cody! Very helpful information for this bad winter time in the Midwest!

Seafoam contains water. The ""other" percentage in isopropyl alcohol is water. Yellow label Heet is methyl alcohol plus solvents with a higher flashpoint and some light oils. Red label (Iso) Heet has some isopropyl alcohol plus other stuff intended to clean fuel injectors.

Cody, I congratulate you on this video. You have shown something that actually has value and explains the problem correctly. There are lots of videos on RU-vid by guys who claim to be certified mechanics and they are lost. My only suggestion is that you should have included Dry Gas, and then simply said: "Of course, you don'y have to use any of these if you use E10."

Thanks for this video. I know nothing really will cause water to suspend in gasoline for long but as you say the the two products on the left just might get the water to move through the system. Thanks again for taking the time to do a real honest presentation.

BRILLIANT! Very well done. The Chemistry teacher gives you an A+.

Just what I needed to know, thanks for the help!

Lived in Alaska for years. Pubic service message was played from September to April on the local channels was great info for using Heet ( isopropyl alcohol). The message was simple, Always add in winter when gas tank in low of fuel. This way the Heet or alcohol will get to the water. Some of us put it in before we drove to get more gas to help it mix with the water that was created due to condensation caused by parking your cars in a heated garage. Heated garages are common as most homes do not have basements and furnace were installed in the garage. Nice warm garage! Taking your car from subzero weather to a balmy 70 degrees twice a day gave you condensation in your tank. Many people who did not pay attention to P.S. message had to drop the tank to remove gallons of water due to the amount built up in tanks. Not until now did I connect the dots to heet and 100%isopropyl alcohol being equal. Thanks.

91% rubbing alcohol work best, we used it in our shops!

I've always wondered what would work best, and now I know! thanks for the video!

Seafoam is a " FUEL" system cleaning /lubricating product, meant more as a barrier to keep moisture away, and from settling, causing rust and corrosion. I know many Ocean Mariners who swear by it. They use it to keep boat motors " PICKLED" during off seasons while in storage.

I wish I saw this a couple days ago, but atleast I found it now to truly understand how this works. Alright now I just have to catch a bus to go grab all these things lol, thank you for the video brotha!

Thanks, just saved me going to a mechanic... I am now boycotting 7-11

I’m in Alaska and our jeep froze up about a week ago. We have it thawed out and the battery holding charge but no fire. This video just saved me from buying sea foam for this. Lol. Thanks especially since Covid, I think I have a good stock of alcohol. Thank you. I know this is an older video but thats the great thing about youtube.

Wow this is great. I just had my carb rebuilt and come to find out my car kept dieing because it had water in the carb. I will definitely get some rubbing alcohol for my tank. thanks alot for this video...greatly appreciated ! I'll try to find the highest percentage I can.

Great Job on the video. Simple and educational.

Thank you so much this happen to me yesterday, Being on a limited income and no men in my family i must give this a try

Excellent video. Thanks

Thanks big time, I had some isopropyl alchahol from another project and it worked like a charm. I siphoned 2 thirds of the gas out of my motorcycle gas tank and put some isopropyl in there, pretty soon misfiring went away and ran the tank dry before putting fresh fuel in. Great tip to know!

heet comes in 2 types but it does work it also keeps your fuel lines from freezing in alaska

THANK-YOU SO MUCH....YOUR DISPLAY WAS EASY TO UNDERSTAND.....

I've been using red HEET for years with the gas I burn in my Suzuki 2 stroke DT100 and found it does a great job removing any water that builds up in the tank. I pore some in the tank before I fuel up everytime. When I don't use it the engine can sputter and even stall out. Sometimes it won't even turnover. Holding the tank to sunlight I have even seen the water in the tank. If the gas is fresh that's not a problem but if you don't use the boat for a few days, get some rain and humidity you'll find water in the tank. With red HEET I have no problems leaving the tanks full for weeks.

Here's a question is it better to add the heat after you fill your tank or when you have less gas in the tank? To me logic would dictate that less gas to the mixture would be better.

Great video, good information, well presented, thank you. I may do a similar video on my channel one of these days but for now I think I'm gonna go with the Heet.

Thank God for men like you!!!

I know an older video, but I can attest to this working. I used the 90% version of rubbing alcohol in a boat I had a few years ago that had a ton of water in the tank. Pulling the tank would have been a focking nightmare.... After a couple fill-ups it was good to go. It hiccup'd and burped a few times throughout the process, but eventually got to where it ran like a champ. All that being said, the boat had an old chevy 300ci straight six in it and I think you could have ran whiskey, rocket fuel, piss, hot lava...just about anything through that bastage and it wouldn't hurt it. Thanks for posting this. I'm sure it'll help a lot of peeps.

Water does collect in gas tanks and fuel lines from moisture in the air, or from the storage tanks at gas stations. Today, however, vehicles in most parts of the country burn gasoline that includes up to 10 percent ethanol, a form of alcohol that performs the same water-absorbing chores as brand-name gasoline antifreezes. Products like gas-line antifreeze Heet - which are available at automotive stores - contain ingredients such as isopropyl or methyl alcohol (methanol), but they function in the same way as the ethanol that is already in your fuel. Gas-line antifreeze isn't expensive and probably can't hurt, but if you have 15 gallons of fuel in your vehicle and 10 percent of it is ethanol, your tank already has 1.5 gallons of alcohol in it. Adding another 12 to 16 ounces of alcohol is not going to provide any additional protection against freezing.

A worthy demonstration, thanks!

Nice test Cody. Thanks.

GREAT video! Many thanks sir

you're awesome,Bro!

THANK YOU,, VALUABLE INFO..

I really appreciate how he chose to use a separate stir rod for every container

great video!..keep them coming!...

Great video, much appreciated.

Ethanol mixes with water vapor in gas tank and forms a jelly that sinks to the bottom. Then when you start your lawnmower or classic car it gets sucked into the carburetor or fuel injectors.Fix:Use quality fuel stabilizer like Stabil. But gas will still turn to jelly after a year, maybe 2 years. Gotta run that mower/car once every 2 months for an hour or more. After a year add more fresh gas and stabilizer.

Handy experiment - helped me decide which product to use b/f buying - thx

Thanks for this informative video, I really appreciate especially since I'm not mechanically inclined.

Thanks for the video. I have two questions. Would you do one for diesel? More and more manufactures are offering clean burning diesel engines to their inventory. I have purchased many additives and each one has its own fuel-to-additive recommendation. Do you think the results would have been better/worse if you would have used each manufactures recommendation on ratio? Thanks again.

In your test did you use pure gasoline or ethanol blended?

wonder what different octane would do for water removal and ethanol free for water removal I've tried bp power for water removal. seemed to push out ALOT of water when it was used.

so helpful thankyou sir!

I just put rubbing alcohol in my gas and my car is running a lot better I remembered I had some in my car thank you so much

Great video Cody. Any thoughts on adding the Heet or Alcohol to a 4-stroke Yamaha JetSki? I believe I have some rain water that got in the tank (kids left gas cap off after refilling it).

thanks for the video. I got gas yesterday and my truck Barry runs now. I didn't know about alcohol but I used heet iso. hasn't cleared up yet. but I plan on pulling my filter and looking at the fuel to see.

just wanna add this thought.. when u read the directions for the additives you add to gas, it says to add before fueling, this is so when you pump the gas, the gas falling into the tank will mix and slush the gas around therfore getting the mixing action he uses with the jars, you wouldnt really need to drive eratically to get it to mix, sure driving eratically would problably help, but you would do that with minimal gas in the tank, so theres room for slushing around.. but pouring in before fuel up is the key to mixing it.

thanks the alcohol really works I put some in my gas tank cause my car wouldn't start was going to drop the tank and remove the gas but I tried this before I removed the tank and it's works thanks

nicely done thank you

Why not remove the tank and have a drain spigot installed at the normal low point(s)? Then after the water should be settled to the bottom the operator may drain the water off and shut the spigot. This is a procedure sometimes used in aircraft during the pre-flight check. (at least on some of the aircraft).

You just added more water with70 percent alchy. Use 100 percent

I worked on marine engines, an FYI use at your own peril, especially in a 2 stroke engine. Doing this, if you notice it does not evaporate the water, basically causes it to bond in with the fuel. What happens it causes a steaming effect and burns through the engine and at the same time what we found removes the oil that is meant to be a lubricant and caused engine failures. Did make a lot of money on engine replacement and rebuilds though.

great test! using isopropyl alcohol to compare against was awesome

On my big diesels, I use 60/40 blend with 1 pint of 70% rubbing alcohol p/50gal. as pretreat in -0 weather. Good for -30+. For -40 weather, I also mix in up to 3% unleaded gas MAX (gas is hard on diesel engines), or you can also go with straight No.1 diesel fuel if available and and 1gal. unleaded per 100 gal. of #1 fuel. Never froze up in 35 years.

Despite the 70% isopropyl used, this was a great demonstration. Thank you for the time and the visuals. 👍

Awesome Job 👌

You’re about to hit 100k!!!

Thank you good video appreciate it

Huge help!

I washed my air filter a year ago and didn't let it dry all the way. And could barely go down the street and uphill. A week ago i put beryman 12 chemtol and it cleared the hesitation. I think I'll just put the seafoam. But am thinking about 99% alcohol also for a good measure! Thank you very much

good video and info

TY so much!!

Glad I found your video as I was cutting grass then added more gas in tank and now won’t start. Gas can was in shed but we had a really bad storm come through 2 days ago. How much of the Rubbing Alcohol do I add? Push mower

Thank you bud!

Actually.... yeah, shake it up. I believe most instructions say to add to tank and then add gas. By doing so, you are stirring quite well; especially in an empty tank.

Thank you! It worked!

Thanks for the education.

awesome video, i have water in my gas tank on the boat, just wondering how much to pour in a 60 gal tank, you said "a little" ..that's kind of vague...wondering how much? t thanks

Thank you kind sir!

Went thru an automatic carwash the other day. Fuel door opened at some point (not sure when) when I got outside to check on it there was water residue around the fuel cap but the fuel cap was shut tight... I cleaned around the surface to dry it but I’m worried that water got inside the tank. Should I worry or since the cap was closed no water got inside

Is that water or Moonshine? lol... Thanks for the video :)

GOOD JOB. BIG TIME THANK U

Well done !!!!!!

Very informative

The whole idea of the additives is to turn the water into a burnable liquid. So you get rid of the water by using it. Doesn't turn it into gas but makes it burnable.

Cody, good video. So, if my gen set has a metal tank I cannot use your formula, why?

sweet dude thanks!!

Probably should have used about a cap full only in each for a little more accuracy but it still answers my question. Thanks mate

two thumbs up thank you very helpfull

I have used the Heat , It works well ! Never new there was a cheaper way man , Thanks!!

What you refer to as "breaking down" the water is actually emulsifying the mixture. The products don't "remove" water, as you've also intimated. Unfortunately removing the water is the best fix and, for that, depending on the amount of water one has, involves work (dropping the tank, etc.). Water through a diesel engine, for example, is never good for the engine and could be very bad.

There used to be a Shell product in Norway called condensate remover(Kondens Fjaerner) and it was Propanol.

Might I suggest redoing this with water with food coloring added.... would be a lot easier to see.

Nice video 👍🖖

Which product would you recommend for Direct Injection/ turbo intercooler engine???

Great video Cody. One question......how much should I put in my car's tank - it has around 10 gallons in?

Ty Sir!!!

Does this work for outboard boat engines? Yamaha?

I hope the Governor of California doesn’t see this - he will come after you for your vintage gas can 😆

Keep in mind why rubbing alcohol works even when it's 30% water itself. Water and gas don't mix. That's why water creates problems in your tank. You engine is getting one or the other and runs badly. But alcohol will bond to both, causing them to mix and carrying them to your engine as a mix, where it will burn in your engine. It's like the ethanol (an alcohol) that is often sold with gas. When I lived in drizzly Seattle, I often had problems with water condensation in my fuel tank. Occasionally putting a small bottle of rubbing alcohol in the tank would solve that problem. As he points out, it's cheap and it works.

Just went through all this with my neighbor's boat, nothing is worse for 2 cycle engine as ethanol fuel. I have owned and worked on marine engines all my life, I once worked in a marine outboard engine shop as a part timer. I owned a shop which sold outboard motors and boats. We always told our clients to use only ethanol free gas in their engines. My neighbor came to me and said his engine would not start. It was a little 40HP Mercury 2 stroke. After checking the ignition system was working, I knew then the problem was with the fuel and carburetor. Sure enough, the float bowl was full of water. I remove the carburetor, cleaned it check it thoroughly. I ask my neighbor if he was using gas from pumps with ethanol, he said I get what ever is at my local stations. Yes, it had ethanol in it. I got a clean tank, new hose and hooked up the engine. It started and ran fantastic. Ethanol or any alcohol is hygroscopic, meaning it attracts water. Where we live is very humid all summer, so when the air (atmosphere) is drawn into the fuel tank the moisture in the air condenses on the walls of the tank. It then travels to the bottom of the tank and is picked up by the fuel line. This will not happen to fuel that is ethanol free. The new engines can use 10% ethanol gas but boats are not used on a daily basis. My other neighbor has a party barge with a 150 Mercury He has spent a fortune on repairs only to have the same problems. I have told him time and time again to have the carburetor rebuilt and clean out his tanks. Now his badge has been setting for 2 years. When storing your boat for the winter use a gas stabilizer. Now he is going to have a real problem.

Good tip

Could you have take some of the mixture of the bottom (using a pipette) and see how well they burn on their own?

Thank you

I used heat for years on vehicles and marine system never failed me, car and boat motion will stur it up for you just need to stay moving and try to burn as much as you can

Cody nice job! I just got a load of bad fuel but I don't know why it's bad other than loss of power. On your video, I think the only thing I would criticize is that you added a LOT more alcohol to your jars than would ever get added to a Car or Truck as tank unless you put a case of HEET in there :) If you put a 12 oz bottle of HEET into 15 gallons of Gas , that mixture would end up being less than 1 percent ( 0.63%) alcohol into the gas - which is Not Much. It would be interesting to see if it works if you put only 2 Tbsp HEET into a jar of 1 oz water and 15 oz gasoline which migh represent a real world situation more accurately. Also wondering if that fuel was E10 regular or E0. After watching this Im thinking of getting a siphon to the bottom of the tank and sucking out a couple quarts to see whats really in there. And if its water - keep going! - Thanks, Sandy.

So does heet in the yellow bottle work as well ?
