vehicle

 

 

They say you should run it through your car every 5000 miles, which is easy enough to keep track of as long as you do it at an even mileage reading and then just keep up with it after every 5000 miles.

The use of this product has many benefits such as:

  • Stabilizes fuel
  • Cleaning deposits
  • Cleans injectors
  • Cleans carb jets
  • Lubes upper cylinders
  • Controls moisture in fuels
  • Add lubricity to fuels
  • Cleans intake valves
  • Quiets noisy lifters
  • Used to De-Ice and as an anti-gel
  • Used as an overall engine performance Agent
  • Can be used on all motor oils, synthetic and conventional

Fuel Tank

 

How Do I Use SeaFoam In Fuel?

It is very easy to use this in your fuel tank. Simply pour the product in your fuel tank.

  • To use for regular maintenance purposes, use 1 ounce per gallon of fuel.
  • To clean your fuel tank you would use 2 or more ounces per gallon.

The more you use the cleaner your fuel system will be. As Sea Foam is produced with petroleum-based cleaning and lubricating contents, this product will not harm your fuel system, so don’t worry if you think you put too much in your fuel tank. Sea Foam works and is safe in all diesel and gasoline engines.

General Rule of Thumb When Adding to Your Fuel Tanks

  • Cars And Trucks – For approximately every 3000 miles you put on your vehicle you should use 1 to 2 cans in your fuel tank. Add SeaFoam to your fuel tank when gas is low to maximize the benefits of the product.

 

  • Fuel Injection Machines – mix the product with an equal amount of gas

 

  • Diesel Injection Machines – Use full strength

 

  • 2 Stroke Machines – add 2 ounces of Sea Foam per gallon of fuel premixed.

 

  • Fuel Stabilizer For Storage – add one ounce per gallon of fuel, effective for up to 2 years.

 

  • Engine Equipment – For engine equipment that is used often, approximately every 3 months you should add 1 ounce per gallon of this product when you put new fuel in the equipment.

 

  • Engines Not Used On A Regular Basis – for all other engines and fuel tanks that you do not use regularly always add Sea Foam to every tank of fuel.

When you pour the product into your fuel tank, it lubricates and cleans your entire fuel system.This works as the product is pushed through carburetors and fuel injectors and eliminates residues and deposits from intake valves, pistons, chamber areas and fuel passageways against damaging your fuel system. Sea Foam is safe to use on types of diesel and gasoline as it does not contain any harmful chemicals or detergents.

How Do I Use SeaFoam As An Oil Treatment?

oil treatment

To avoid oil flow restrictions use Sea Foam as it also acts as an engine lubricant. It is safe to use on all motor oils.

Adding  SeaFoam Motor Treatment to gasoline and diesel crankcase oil benefits are:

  • Cleans oil control rings, actuators, vvt solenoids
  • Cleans and quiets noisy timing chain tensioners  and noisy lifters
  • Reduces diesel injector restriction
  • Safely liquefies petroleum residues to prevent flow restrictions
  • Lubricant
  • Cleans deposits and diesel soot residue throughout the crankcase
  • Heavy oil deposits and residues drain during an oil change

Directions For Use

To use for your engine’s crankcase you first need to determine its oil capacity. Traditionally passenger cars and light trucks consist of 5 or 6 quart systems.

Your vehicles owners manual will tell you exactly how much your crankcase oil capacity is. General rule of thumb is one 16 ounce can of Sea Foam can treat up to 16 quarts of oil.

For every quart of oil in your crankcase add one ounce of this product. Simply remove the oil filler cap and pour in the required amount of Sea Foam you should use directly into the crankcase of the engine.

When using it in your crankcase it prevents sludge buildup, harmful oil formations and cleans your internal engine parts.

Note: Do not treat your engine crankcase more than once per oil change. It is recommended that you add the motor treatment approximately 100 to 300 miles driven prior to an oil change.

How Do I Use SeaFoam As A Motor Treatment For Storage?

vehicle storage

When you add this to a fuel tank prior to storage, it helps to prevent fuel evaporation, gum & varnish formation, preserves ignition vapors and adds lubricity. Sea Foam acts as a fuel stabilizer for up to 2 years.

Directions For Use

You should add a minimum of 1 ounce of SeaFoam for every gallon of fuel in the tank.

Then run the engine long enough to push the treatment through the whole fuel system.

It works best when the fuel level in the tank is low as it increases the lubricating and cleaning ratio, then top up with fuel afterwards.

After storage, your engine will start up easier and your engine will last longer when you have prepared it for storage. This is a great product for motorsport vehicles that are used seasonally.

  1. I tried stp fuel injector cleaner and nothing would this get rid of tge hesitation when step on the gas

  2. My 1997 jeep Grand Cherokee was sitting for 2 years when i drove it the first week 3 days in it started to stall engine would race and and die I bought a can Sea Foam put 3/4 in oil and the rest in the gas tank drove it home 3min away got home let it run for 5min engine stop racing and when it would normally die in park it ran the whole time didn’t die and engine stop knocking i then drove it for 10 min and it didn’t stall knock or die anymore truly amazing product would recommend it to any and everyone with similar symptoms It was well worth the $8.99 instead of the outragious mechanic cost i wasn’t looking forward to paying
    I give it 10 👍🏿👌👍🏿👌👍🏿👌👍🏿👌👍🏿👍🏿👌👍🏿👌👍🏿👌👍🏿👌👍🏿 up!!! !!! !!!!!! !!! !!!!

  3. 07 Mustang Gt 51kmi. Had a pinging at high rpms. I sprayed the throttle, added some to my tank, some to my oil and its been running great. I was very skeptical but seafoam appears to have changed my car into a new machine.

  4. When my motorcycle sits for a month or more the pilot jet gets clogged. In the past I would take the carb apart and clean the pilot jet but think 10% ethanol gas leaves a coating that I can’t clean completely, leaving the motorcycle hard to start.
    I put Sea Foam in the gas tank and was astounded at how well the bike started and ran. Completely cleaned the carb! I now run it in my Tacoma whenever I notice pre-ignition. Takes care of that, too. Great product!

  5. Used this product in my car as a last resort before hiring a mechanic last week. My Ford Taurus was beginning to sound like a 2 cylinder John Deere tractor and would die each time I stopped at a light. I replaced the plugs & wires, added fuel injector cleaner, cleaned the MAF sensor, changed the gas filter & the air filter; nothing worked. A friend of mine added 7 ounces to a half tank of gas and I drove it for day & a half to work and back. I was certain that it wouldn’t worik either. To my amazement the misfiring began to quieten down after around 40 miles. By the time I had driven 90 miles it was running more smoothly than I had ever heard it run. My gas mileage is currently at around 30 mpg (3 more than originally advertised). It’s made a believer out of me. Try it guys if you’re at the end of your rope.

  6. I’ve never been a big fan of auto additives to gas or oil – as they always seemed like a lot of hype. My auto mechanic swears by Sea Foam so I bought a can and added it to the gas tank on my son’s 1987 Jeep Grand Wagoneer before he drove from Pittsburgh to New Hampshire this week. That 6,400+ lb beast always got between 9 mpg and 11 mpg – but after adding Sea Foam during my son’s trip he got more than 20+ mpg the whole way. A $ 12 can of Sea Foam saved my son more than $ 100 in gas. That’s a pretty good product !

  7. Outstanding product. I run Seafoam with every tank of gas in my lawnmower, no carburetor issues after twenty years – small engine carburetors are notorious for being problematic after they’ve been in service for over a decade. I also put an entire bottle in each of all my vehicles once every month, to keep the injectors clean. No fuel related issues in my three cars with a combined total of over 750k miles. I highly recommend this product.

  8. I have been a ASE Certified mechanic for 13 years, running my own shop I first used seafoam on a 50s model Studebaker that someone had put a 350 with 327 heads and POORLY timed. The engine had so much carbon buildup after it was properly timed it would continue to run with the key off, this was due to the carbon buildup burning and continuing to burn fuel. 1 can later and the thing ran like a bat out of hell it was truly amazing. I have since continued to use Seafoam in all my vehicles old and new and I recommend it to ALL my customers complaining of poor performance before they ever bring it in to me, I would say 90% never come back for repair of the problem, they do however return to thank me. Why would I as a Man making a living cut myself out of money. 1) I am not a crooked mechanic. 2) It works and I would recommend it if it didn’t.

  9. My wife’s bike has been sitting idle for the last 8 months. Cranks but will no start, so I bought a can of Seafoam and 3 days later it started right up. It cleaned the fuel system of all the varnish and runs great. Thank you Seafoam.

  10. Sea Foam is a great product , I even use it to clean the grease off my hands (soak in cloth or paper towels not directly ) , It works great in the engine , as a gas treatment ,fuel injectors keeps them clean , carburetor, lawn mower and for oil changes . I am very happy with this product . It has served me well . I sometimes get a special at auto zone two cans for $16: 00, check you local Auto zone . Sea Foam keeps the grease off and the increases the performance .

  11. I use this in my 2004 trailblazer. It keeps it running smooth and at WalMart costs only $9. I put it in my car with every gas fillup.

  12. There was a TSB for moisture build up in the fuel rail on the wife’s car. As one could imagine the dealer wants a bunch of money to fix it. Two full tanks with seafoam and every problem it caused was gone. The residual effect was mpg went up for long after I used it. So now I give it two doses in a row when mileage starts to drop again.

    I don’t have any it fixed my broke engine stories, just what it did when it was used to remove moisture from the fuel rail and its lasting effects.

  13. I was ready to give my car back to the bank … too many recalls to mention with my 2010 Chevy Cobalt …… the car has killed several people ….. and the loss of power warning lamp comes on in the car … when all the power decreases in your engine leaving you stranded in no mans land …. I used Sea Foam today … and Instantly … my car performed like brand new ….. I poured the entire contents into my gas tank .. with the engine running …. I then topped off my gas tank to the limit .. and drove to work 80 miles …….. and had All my power restored … all the jerking and car shutting off has stopped … and I could not be happier! …. The best product I have ever used …. hands down!!!!!!!

  14. Sea Foam does work. I used it once in my ’78 Cadillac and the fuel performance was much better, there was noticeably smoother and faster acceleration. It reduced my carbon deposits in the combustion chambers, although it did not instantly remove all of it. I say that it is a good product for keeping your carburetor clean, and it helps keep the cylinders cleaner. You do get your money’s worth, but don’t think it’ll make your 200000 mi car or truck completely like new.
