Sea Foam Motor Treatment Fuel & Oil Additive, SF16, 16 oz, Pack of 3

Used this for the first time in two very old and well used small engine carburetors with outstanding results. The first one was a 23 year-old John Deere lawn tractor that always was hard to start after sitting for a few days. I thought for sure I either needed to rebuild the carburetor or replace it, but decided to try this instead. I followed a pretty simple how to video I found online, poured this stuff straight into the carburetor through the air intake, and now it starts on the first tap of the starter every time. I don’t want to say this stuff is magic but it saved me a lot of work. The second was a 35 year old push Toro lawnmower with the original carburetor. Although it was running pretty good before hand, you can clearly hear a difference after using sea foam now it starts smoothly on the first pull and runs better than most new machines. I highly recommend sea foam for anyone who’s having similar issues or just wants to maintain their equipment. I’m now adding it to every gallon of fuel that I use in my lawn equipment.

Good product. Can clean your engine while you drive, also will clean your fuel injectors. In the gallon size, it’s more economical than buying the pints. Also can help stabilize fuel for long term storage.

Many times repeat buyer! Use in everything gasoline powered and help for over winter storage in gas cans!

I use this for preventative mtc, I'm not sure it does anything, but my car has 70,000 miles on it, with no major engine troubles yet. Once or twice a year, I'll put a couple cans in the gas tank before a long road trip to help keep the fuel system clean, and about a week before every oil change I pour half a can into my engine oil. I believe it helps keep my fuel system, and internal moving parts clean, but I don't have x-ray vision, so I can't really tell.

Bought the three pack. My 2020 Ford Explorer was averaging 18 mpg. Used per instructions in gas and oil. Now getting 23mpg. Two thumbs up!

My order of Sea Foam was delivered in a timely manner and, the most important thing, was it worked like a charm. It turned a very old lawnmower into a durable piece of machinery.

Can't beat this !
