Thanks for the question, Terry!

Yes, you can use Sea Foam Motor Treatment in your Jeep. It’s compatible with any gas or diesel engine. Just follow the instructions on the can.

Here’s a little more info on how to use it:

• Sea Foam Motor Treatment in fuel. I like to wait until the tank is low (1/4 -1/8 tank), add the whole 16 oz can, and then drive for at least 10-20 miles before refueling. It’s safe to add a high concentration like that and it works very well for cleaning fuel residues and deposits. Add it to fuel like this every 3,000 miles or once a year.
• Sea Foam Motor Treatment in oil. Add 1 ounce of Sea Foam per quart of oil in the crankcase. We recommend adding it 100-300 miles before your next oil change. That gives the Sea Foam enough time to circulate and clean, and it allows all the reliquefied oil residues to be drained away with the old oil. To help progressively clean up your oil crankcase, add it before every oil change.

Hope that helps and let me know if there’s anything else!

Good question, Art. We get asked a lot about ethanol.

No, Sea Foam does not neutralize ethanol.

What it does do is help stabilize fuel and help protect against the harmful effects that can occur as ethanol-blended fuel ages, such as gum and varnish formation. It also works to clean fuel residues and deposits that can affect engine performance.

If you’re storing equipment with ethanol-blended fuel, add 1 ounce of Sea Foam per gallon of fuel before storage and run the engine for a few minutes so the treated fuel circulates throughout the fuel system.

Hi Rhonda,

Thanks for the question!

Yes, you can absolutely use Sea Foam Motor Treatment in your 2005 Chevy Impala. It’s safe and effective for that vehicle. Just follow the directions on the can.

Here’s what I’d do to get the most cleaning power:

• In the fuel: Wait until the tank is low (about 1/4 tank or less), add the full 16 oz can, and then drive at least 10–20 miles (or until nearly empty) before refueling. The higher concentration works much better and faster to clean fuel residues and deposits.
• In the oil: Add 1 oz of Sea Foam per quart of oil 100–300 miles before your next oil change. This helps clean oil residues and deposits so they can be drained away with the old oil.

Sea Foam is a great preventative maintenance product and can also help if you’re experiencing issues related to fuel gum and varnish.

Hi Jim,

Thanks for the question!

Sea Foam does not have a shelf life. As long as the cap is on tight, Sea Foam is good to use. It’ll last a long, long time (decades).

Thanks for the question, Theresa.

Fuel gum and varnish is the #1 cause of engine problems in a small engine like a lawn mower. Cleaning the fuel system with Sea Foam is a good place to start. You’ll want to use a high concentration of Sea Foam Motor Treatment. Drain the old fuel if possible, then mix Sea Foam with fresh gasoline at up to a 1:2 ratio (1 part Sea Foam to 2 parts fuel). Start or crank the engine long enough to draw the mixture into the carburetor, then let it soak overnight—or up to 48–72 hours for severe deposits. The high concentration works much better and faster to dissolve the fuel gum and varnish that clog carburetor passages and jets.
