Hi Les,

Thanks for the question! You can use Sea Foam Motor Treatment in your diesel tractor. Just follow the directions on the can. Let me know if you have any other questions – happy to help!

Hey Frank,

Good question! If the problem is being caused by fuel gum or varnish, Sea Foam will help clean it up. Here’s what I’d do. Since your gasoline is fresh, you don’t need to throw it away. Drain most of it back into an approved fuel container. I’d actually recommend a bit stronger concentration, up to a 1:2 ratio (1 part Sea Foam to 2 parts gasoline…which is 8 oz (half a can) of Sea Foam in a pint of gas).

Start by draining the carburetor. Then, try starting or cranking the engine several times to draw the mixture into the carburetor. Getting the treated fuel into the carburetor is the main goal. Then let it soak overnight. The high concentration gives Sea Foam a much better chance to liquefy the gum and varnish that may be blocking the carburetor’s small passages.

If it still won’t start after the treatment, the problem may be something other than gum and varnish.

• For regular maintenance: Add about 1 oz per gallon, so roughly 17 oz (500 mL) for a full tank.
• For cleaning: Rather than treating all 65 liters, I’d wait until the tank is 1/4 full or less, then add a full 16 oz (473 mL) can of Sea Foam Motor Treatment. Drive at least 10–20 miles before refueling.

Thanks for the question, Carl. Yes, you can use Sea Foam Motor Treatment in your 2014 Chevy Impala. It’ll work great in the gas and oil to clean residues and deposits that reduce performance. 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!

Thanks for the question, Fred. If you suspect there is water in the tank, use an isopropyl product like Heet. Sea Foam will help control small amounts of moisture in fuel, but something like Heet is designed for larger amounts.
