ADD TO
FUEL TANK

HOW MUCH?

For regular fuel system maintenance, add 1 ounce per gallon of fuel.
For cleaning, use 2 or more ounces per gallon to a low tank of fuel – the more you add to fuel, the better it cleans!

HOW OFTEN?

For cars and trucks driven regularly, put 1 to 2 cans of Sea Foam in your fuel tank every 3,000 miles. For vehicles that sit between use, add to every tank of fuel.

ADD TO OIL CRANKCASE

HOW MUCH?

Add 1 ounce for each quart of oil in the crankcase. Just remove oil filler cap and pour directly into the crankcase.

HOW OFTEN?

High Mileage can be added at any time during the oil interval. For best results, we recommend adding to oil 100 to 300 miles before every oil change.

ADD TO FUEL FOR STORAGE

HOW MUCH?

To stabilize fuel for storage, add 1 ounce per gallon of fuel. After stabilizing fuel, run the engine long enough for the treated fuel to work all the way through fuel injectors or carburetor passageways.

HOW OFTEN?

Add to every tank of stored fuel. For best results, add when fuel is fresh.

QUALITY OF PRODUCT
SMOOTHER IDLE AND MORE POWER!
“I drive a Toyota Matrix with 247,000 miles on it. I’m a second owner on it, and maintenance has been kept up regularly by myself but not so sure about previous owner. Like any vehicle with this many miles, it has had a bit of a rough idle. I suspected the injectors might be getting dirty and possibly need replacement. I had run other fuel system cleaners through it, but it’s always been a bit rough. After running High Mileage Sea Foam, I’ve finally got it running smoother and it even seems to have a bit more power, which with this car, every bit of that counts. Super happy with this, and will continue to use on a regular basis.”

THANK YOU SEA FOAM
“This stuff did exactly what I was hoping it would – make the engine run smoother. I have a 1992 Sidekick with 233k that is regularly abused. It’s my gambler, trailblazer, and daily driver. I added the full bottle to about 1/8th tank of fuel and drove it “normally” for about 50 miles. By the end of the trip the engine didn’t feel near as rough at idle and my throttle response seemed better. I’m overall impressed with the product and would definitely use it again! Thanks Sea Foam!”
