I have been using Seafoam in my 2008 Dodge Nitro 3.7L with 334,678 miles on it. I've been using Seafoam in the fuel tank every 3rd tank, added to the oil 200 miles before I change my oil and I've used the Seafoam fogger 2 times and the engine runs like it has 30,000 miles on it. I swear by Seafoam products!
Seafoam is AMAZING! I bought a vintage HONDA MB5 (2-stroke, 5-speed manual clutch, 50cc, 7HP, exported to USA in 1982 only) street bike, and although it started and ran, it 'bogged down' a lot, with bad throttle response, and only did 35 MPH. I knew that top speed of this fun little bike is 55 MPH. I added Seafoam to the gas, and about 3 tankfulls later, the bike completely 'opened up' and ran like a clock, easily hitting it's top speed of 55 MPH, with flawless throttle response! I honestly could not believe what I was experiencing, but Seafoam 'restored' this old bike to it's original performance!
Just wanted to say this stuff works!!! I bought a 1995 evinrude 9.9 2 stroke that wouldnt stay running at low idle. I did a few sea foam treatments like displayed in this video, and after a while of playing with the throttle to keep it running it cleared out the carb and now idles perfectly at low rpms. Thanks! Also, there was a LOT of greyish gunk coming out of the exhaust water flow.
Jerry Odell My 7.5 Mercury 2 stroke does the same thing. This weekend I’ll try this method. Hopefully I have luck because I’m ready to hit the water man
I put this in my Polaris, it wouldn't start, the fuel system was blocked, the carb jets we're awful. Dealer quoted 2500. Put it in the tank, best product out there.
Just tried a full can of seafoam today on my 2006 Ford Escape 3.0L V6, I was at 3/4 of a gas tank when I used the product and drove for a bit after adding it. My issue was while on the freeway driving above 3kRPM closing towards 4, I noticed hesitation and loss of power. I was recommended this product hope it does something beneficial for my acceleration issue.
Look into faulty ignition coil and/or worn plugs, dirty fuel filter, dirty MAF sensor... Go to a parts store and have the engine codes read for free, go from there.
@@SeaFoamOfficial Sounds good I’ll have those codes pulled again. Thank you for the response. I’m aware I did have a prior ignition coil problem, maybe another coil pack has went out. Would the use of seafoam which I never used before and my car does have a lot of miles still be beneficial in my situation?
@@keembrown5658 Sea Foam works great to keep fuel injectors clean... But I always like to answer by suggesting to look into the key causes of hesitation (coils, wires, plugs, filters). When using Sea Foam to clean, add a can or two when the tank is LOW to max the cleaning concentration. Adding 16 oz (1 can) to 3/4-full tank won't have as much of a cleaning punch. Hope this makes sense!
this stuff works nice. was trying to start my generator and wouldnt start, i took plug out cleaned it and even put gas in the plug hole to prime it, but still wouldnt start. So then i thought hey put some seafoam inthe plug hole and started first pull and kept running fine. So i have a wheeled weed wiper and same thing it was sitting thru the winter and wouldnt start so put seafoan in plug hole again first pull!!!! Im impressed :)
The smaller the fuel tank, the easier it is to add high cleaning concentrations of Sea Foam! Also want to make sure that you understand that cleaning carburetor passageways requires Sea Foam in the fuel. Adding Sea Foam to a plug hole adds lubricity and soak cleaning to cylinder cavities - what it takes to help your engine's fuel delivery (carburetors or injectors) must be mixed into the fuel.
I have a 2006 polaris ranger 4x4 carburater injected I had about 4 gallons of gas in it. I was trying to measure it out to use half a can but I used the whole can of seafoam. Lets just say ita going to be cleaner then clean in that carburater
Hi believe or not I have a 03 ford f250 6.0 power stroke. 3 injectors fault after parking for 2 months. Auto parts store recomend the sea foam I dropped 2 cans in 3/4 of the diesel tank an wow I have 1/4 of the diesel tank an injection issue disappear Run like champ any way that's really work.🤝👍
Most auto parts stores in US and Canada can offer. They are direct shipped so not in the stores. Contact your favorite auto parts store and work through the wholesale people. Contact Sea Foam through our website's Ask Jim feature if you need any help.
Hi Quinn: The point is never made to run all that Sea Foam in one engine treatment. That would be ridiculous (we agree). The points are: Sea Foam is ALWAYS safe and high concentrations are always an option for stronger cleaning - Sea Foam is used as the treatment of choice in professional induction machines (added direct through the fuel rail) all over North America. Induction cleaning machines use 50% ratios.
Sea Foam Official When should I use Seafoam on my car, it has 130k miles, I have used fuel injector cleaners before but looks like nothing changed much considering a can was a dollar.
Please see the video, SEA FOAM IN FUEL. Additionally, consider using Sea Foam Spray through the intake to clean the upper engine (intake valves and combustion areas).
Mixed 2 gallons of seafoam to just about 2 gallons of gas in my 1997 Acura EL tank. The car hesitates under acceleration, knocks a bit under full throttle and runs rough. I hope I am not putting the engine under stress. When taking off from stop it feels like I am just learning how to drive manual transmission lol
A high concentration is one thing, a high volume of a high concentration is another. You're going to have trouble with too much lubricity and lack of fuel vapor volatility. [Be prepared for your car to run terrible and likely foul plugs when you cold start.] I would siphon a bunch of that mix out of your tank into a fuel can, then fill the Acura's tank with fresh gas. Re-use a portion of what's in the fuel can as you cycle through tanks of fuel.
@@SeaFoamOfficial Will do. Yes my car runs terrible on cold starts. Lots of smoke out the tail pipe but when warmed up to operating temps runs smooth. I did lots of full throttle runs under load and high RPM to the redline. Slight pinging in 3rd gear could be heard. Didn't misfire under load just in low RPM during take off. Based on my description do you think my Acura sustained any possible strain/damage? I am going to change the spark plugs anyways but other than that anything else I should watch out for. I am going to go fill up with a full tank of fresh gas. I just about ran my half a tank of 50/50 to 1/8th as we speak. Oops
Hi i had water in my tank so i drained the tank and filled with fresh fuel and changed the filters i filled the filter half way with sea foam as in the other video and run it but im not quite getting full power . When you hot soak it for 5 mins would it be any better to leave it soak over night? i suspect my injectors are dirty they are prone to it on 115 yamahas so going to try this method
Do you have water in a boat fuel tank? If so, drain fuel (seems you already did to) and add a few 12 oz bottles of isopropyl and at least two gallons of fresh fuel and run through the engine till the fuel is out. Watch our 'Can & Hose' method for cleaning the injectors.
Hi Rachel - For cleaning carburetors, here's what I would do: When the fuel tank is very low (less than a gallon), add a full can of Sea Foam to the fuel tank. Start and let the engine idle for 10 minutes to draw the Sea foam concentration into the carburetor circuits, then shut it off and let everything sit and soak for a night (or 2, or 3...longer is better). After sitting, add a half tank of fresh gas, start and let it run for 10 minutes to burn off all the hydrocarbon residue...then road ride it once the idle is steady.... At that point your carburetor circuits should be clear and you will have ZERO doubt about Sea Foam's ability to clean things up! Let us know what happens.
The idea of the video is to help understand that more can be added when higher concentration cleaning is needed. We much appreciate your comment about the the can instructions --- Note that can instructions have been revised with cleaning dosage specifics (look for updated versions later this summer).
i have a 100 gal fuel tank in my boat that has not been started in 5/6 years. the fuel was treated heavily with another product. i have now acquired a newer motor for the boat. Is the fuel in the tank still usable. Will Seafoam help clean up the tank.
Hey Jeffrey: People call our tech line often about having large boat tanks full of old gas... Just be very confident that the old fuel has lost its "bang". It loses light ignition vapor and becomes heavy, less volatile, causes residue throughout the fuel system. My encouragement is find someone that can handle all that old fuel and have a repurposeful use for it.
Must go in the gas tank to pass through injectors. (Add a can or two when tank is low.) Going through the vacuum line does not pass through the fuel injectors.
Should I switch to higher octane gas when I use a higher concentration of Sea Foam in the fuel tank? Would the higher concentration of Sea Foam cause engine knock?
I will be adding seafoam to my gas tank shortly. What are some normal effects to be aware of? Will it smoke (or is that just if poired in the engine)? Smell differently? Etc Can i add 16oz to my 4 gallons in the tank for best cleaning and be fine? Or should i fill up first?
Hi Rebecca: You will not see or smell anything different. The vapor/smoke people like to talk about occurs when added directly into the upper engine. That's different than adding to fuel.
For engines that use fuel that's not used up within 3 weeks at a time we recommend Sea Foam in every tank of fuel. For cleaning, the "Can & Hose" method is tough to beat. See HOW2 instructions (website) and/or the "Can & Hose" videos on the Sea Foam Official channel (YoutTube). Do one time per year + Sea Foam in every tank.
I have a 16 gallon tank in my car. I'm thinking my injectors are dirty but before sending them off for cleaning I'd like to try this first. How much should I add to my tank? And is it the same bottle that comes with the curved straw for the intake? I really don't want to put the wrong stuff in.
For cleaning, always try to use a higher concentration. Wait till your tank is very low or near 1/8th. Add a full can and drive at least 20 miles before adding fuel.
Sea Foam Official i accidentally missed a couple of steps but the Seafoam definitely cleaned the engine like you said it would! I did spray into both spark plug holes like you directed
I have a little old yamaha 125 two-stroke that I pre-mix the gas in. It desperately needs cleaned out. Can I add seafoam to pre-mixed gas? If so, how much. I know the video says any amount works but I really dont want to hurt anything.
Yes, can add to premix. Adding a high concentration of Sea Foam won't hurt anything. Add a half can...run the engine for 10 minutes...shut off and let sit overnight or two. Then run as normal...see what happens!
My 1995 Volvo 850 has an 18-gallon has tank. It currently has about 3-4 gallons of gas in it. I want to add a full can of Seafoam to the tank. I live 7.2 miles from the nearest gas station. Do I add all the Seafoam before leaving home, and then drive to the gas station? Or do I wait until I get to the gas station and add it to the tank before fueling? Or do I add a little Seafoam before driving to the gas station and then add the rest right before fueling? The reason I ask is that one of your videos says you can use as much as 50/50 Seafoam:fuel and I don’t want to add too much Seafoam and drive on it.
To max cleaning concentration, favor adding the whole can when the tank is low and drive. Add it all and go...And doesn't mean you can't keep going to a station that's further distance.
I have a 4 Polaris slingshot with a 5 speed manual transmission. Someone recommended running a bottle of sea foam through a full tank of gas. Any thoughts or recommendations on this ? Sea foam official still run this channel ?
Hi John: Going 1:1 with that great of volume is total overkill - don't do it. (You can accomplish the same results with considerably less volume.) The idea behind making the high concentration video is NOT to recommend, but to demonstrate that it can be done and that Sea Foam is always safe on parts..and cleans upper engine areas. Just because a guy eats 50 hot dogs (excessive) in a contest doesn't mean it's prescribed as something wise to do. Hope this helps!
I've got an oil injected 2 stroke outboard. I've never had an issue but I've heard that the oil can gum up after sitting for periods and seize up the motor if the flow stops. Would Seafoam mixed with the oil in the oil injection tank possibly be a preventative? If so what would be a good ratio?
@@JamesWhite-tg4kw No, you still have 100% of the gas and 2-stroke oil you started with + Sea Foam IS a petroleum lubricating oil, so you're adding oil/lubricity to the mixture.
I have a go kart with a 212cc predator engine that has been sitting for 2-3 years. I tried to start it several times and it would turn over and then die. I let it sit overnight and tried again in the morningand the motor would not turn over. Would Seafoam fix this problem and allow for the motor to start?
It will definitely help if your fuel passageways are gummed up/varnish. Remove the fuel, then add a half can of Sea Foam and a pint of fresh gas to the empty tank. Crank it several times to draw the Sea Foam mix into the upper engine. Let it sit for a day or two to soak. If it starts. you resolved a varnish problem. Just add more fresh fuel and go. Let us know what happens!
Not at all. Water, for example, is a solvent. It can dissolve salt and sugar and other stuff... Does not mean that its harsh or harmful. Hope this helps!
Adding to oil works to reliquefy heavier crankcase forms (treats a different area than intake, which is combustion/top end). Do not add thru intake line - use Sea Foam Spray through the throttle body. Hope this helps!
Sea Foam Official So where does all the cleaned out gunk from injectors, ports, piston and rings, combustion chamber go? Would not all the debris from this process then pass through the cat convertor possibly blocking it?
@KARLOZ LOPEZ Yeah funny about that! The gunk just magically dissapears just like their reply! All that gunk cant get burnt up and vanish thats for sure
My motorcycle was backfiring from one or two cylinders and gas mileage was down about 10mpg (typical about 45, now about 35). I put a whole can in with about half gallon of gas in my motorcycle and ran for 5 minutes, then shut off and let sit overnight. Next day I ran it for 20 minutes sitting in garage on idle with lots of revs occasionally. Hot day and engine got very hot (engine is air cooled, no radiator just a small oil cooler). Lots of smoke from exhaust so I figured just let it keep running until smoke is gone. After about 20 minutes suddenly engine started making a loud tapping or clicking noise. Shut off engine and let cool overnight, started next day and noise remained. What did it do to my engine? It's a 1991 Honda Nighthawk 750 with self adjusting hydraulic lifters. Noise seems to be coming from top of engine above one of the four cylinders. Stuck valve? Broken lifter? Please tell me I didn't ruin my engine. What do I do now? I do regular maintenance and oil changes and don't ride hard.
No I didn't check the plugs. The noise came on very suddenly. It's definitely coming from the #2 cylinder exhaust valves' tappet/rocker arm area. I took the valve cover off and removed all 4 spark plugs and pressed and held the starter to turn the engine without ignition but the noise doesn't happen. Installed plugs and started engine and ran for a few seconds (valve cover still removed) and heard the noise. So the noise happens when engine is running from ignition but doesn't happen when engine is turning from the starter without ignition.
Hydraulic tappets so no valve adjustment is possible. Only thing I can think it could be is one or both exhaust hydraulic tappets failed (2 per cylinder). It seems highly unlikely that 2 tappets would fail at the exact same time, so I'm guessing it's just one of them. The question I was hoping you could answer is what caused it. Like I said the noise came on suddenly. Update: Upon closer examination I see that one of the exhaust valves on the #1 cylinder is stuck open. (The rocker is not on the cam lobe but I can see about an 1/8" gap between the rocker and the cam, and the valve stem is lower than the others.) I'm confused because the noise was coming from the #2 valve area. So now I think the #2 tappets are ok but the #1 valve is stuck open. Any tips on unsticking the valve without going through hassle of disassembling engine to get at valve? I would think the Seafoam would've cleaned everything and made things less sticky, not more sticky. Update: The valve does move up and down from the cam lobe but does not close completely when off the cam lobe.
Adding Sea Foam to fuel goes through the fuel intake/combustion side so has no relationship to stickiness that can occur around cam parts. To clean the oil side areas of any 4-stroke engine you would add Sea Foam to the oil crankcase (1.5 oz per quart). Sea Foam in oil works to reliquefy any sticky oil residue that may be causing parts to stick. Obviously, it won't overcome worn or damaged mechanisms. What I'd be looking for is corrosion or burnt oil crud on valve guide/s. Other is that your valve gap is caused by a bent or worn part anywhere from rocker (bent) to pushrod (bent) to lobe/cam (worn). I don't see any way Sea Foam can help. Wish it were an easier fix.
So I tried this on the lake mixed 50:50 sea foam gas mixture and ran motor for about 10 minutes. Now my motor will not turn over. Any ideas what could be wrong? My motor fired up on the first turn all year long.
You need to start with a hot intake to run that high a concentration. Without a hot upper engine you can foul your plugs. You do NOT need to run 50%. That's not the point of the video.
Well, you signed off your video saying "never be bashful went it comes to adding seafoam to fuel." So I went with 50 : 50 mixture. Do you have any recommendations to fix my problem? Do I need new plugs?
I get it... Sorry you're having trouble. Want you to call our tech line so I can help you through the matter. The only harm possible is fouled plugs - Just pull them out and if the white center electrode/s are charred you need to clean (burn off char with a stove flame) or replace. You'll also need to add gasoline to increase fuel volatility. How much fuel is in the tank?
I have a 2-Stroke 98’ Mercury 150xr6 oil sensor bypassed. Do I mix my 50:1 ratio with the gas or just gas and seafoam? *i premix my gas as of right now*
Thank you for replying. Should I change the old fluid since I just added the regular Seafoam a couple of days ago, before I looked at your video? I did not know about the Trans Lube until now.
Sea Foam Official thanks very much for the prompt reply I haven’t used the boat in about a year and a half what would be the best way to make sure it gets a good concentration into carbs to clean them in case of any old 2 strokes still in there? Would this dissolve that and clean carbs if that is the case? Thanks
See our "Can & Hose" video. Yes, would dissolve/liquefy the old fuel residue/gum/varnish that will form in the carburetor circuits. (It's gum and varnish that causes fuel flow restrictions in carburetors and injectors.)
Yes, for sure. Get the old fuel out...add a can of Sea Foam and half a gallon of fresh gasoline...remove the plugs and crank the engine for 10 to 15 seconds...put the plugs back in and let things soak for a couple days, then try to fire it up... The soak time will work to reliquefy all the old fuel varnish from the carburetor circuits.
Sea Foam Official thanks for the quick reply. Here’s what I already did-I drained all old gas down to like 1/2” then added a bottle of redline and half tank of fresh gas then was worried about condensation so I filled tank rest of way and added a bottle of sea foam. Then changed spark plug and fired right up! But have to keep giving it gas to keep running. And it smokes a lot but I figured that out today after watching seaFoam videos. Should I add more bottles seaFoam since theres now 3gallon of gas ? I’m trying to avoid taking the carb off machine and having to rebuild as ppl say it’s a tight fit. And tricky carb to work on according to some.
Sea Foam Official I was thinking if my math is correct,I need to add 5 more bottles of seafoam to the 3 gallons. Have to fix front & rear brakes and change brake fluid & oil. Then will go riding and burn through the 3gal. Everyday I’ve been spraying seaFoam Creep into air intake while motor is running. Then shut off and let soak. Thanks for your advice.
@@dw4940 By adding more you're spending too much money and making a bigger mess to clean up. If you don't want to wait to run the fuel through the engine, siphon it out, put it in your car/ruck tank, then start over with the initial recommendation.
So this isn't too much of a solvent to run through a diesel injection pump, i have used it on my gas engine with awesome results but it seems like its to strong for the pump to stay lubricated properly on 100% seafoam
Can't know without more information but common cause of rough running is petroleum forms that impair fuel passageways. Fuel system and upper engine residues are variations of unburned hydrocarbons whether heavier fluid gum forms or deposits around injectors, valves and chamber areas.. Sea Foam (petroleum) works to clean by safely dissolving petroleum residues, helps clear things out.
@@alejandrotobienne584 The can shows for Autos & Trucks: Add every 3,000 miles. That's a decent general rule. It never hurts to add more frequent if you wish. Every 3 tanks will work great!
Hi Kevin: Yes, if Sea Foam overcomes a fuel system issue. Is there something going on with your engine? What engine? What issue/s are you experiencing?
Try this: When you fuel tank is very low (less than 1/8 tank), add 2 cans of Sea Foam and drive 10 tor so miles...shut off and let sit overnight or longer. Then drive again and add fresh fuel. Sea Foam Spray through the throttle body would also help clear things up.
Keep adding a half can toward the end of each oil interval. Will clean things up if the lifter noise is caused by sticky deposits. If you ever have doubts, drop a glob of heavy crankcase goo in a jar of Sea Foam to get a visual idea for how it works... In your crankcase, Sea Foam works to liquefy heavier/sticky oil residues (so they drain away). Simple, safe...
