Thanks for the question, Terry. As long as the treated fuel is going through the injector, Sea Foam will clean it. To get the greatest cleaning power, I’d add a high cleaning dosage of High Mileage Motor Treatment to a small amount of fuel. Add a full 16 oz can of High Mileage to the fuel tank (you can add up to a 1:2 ratio of Sea Foam to gas. You can add less than a 16 oz can if you’ve only got a little bit of fuel in the tank to hit that 1:2 ratio. A full can is easiest though and works well.)

After you add the High Mileage, make sure you run/idle it for a while to give the it a chance to make it through the fuel system and clean. Use up that entire tank of treated fuel before adding fresh gas.

Thanks for the question! Yes, you can use Sea Foam Motor Treatment in any gasoline or diesel fuel, including ethanol free gasoline. Just follow the directions on the can.

Thanks for the question! If the fuel is two years old, it should still start and run fine enough to get you to the shop.

After you get it back from the shop, your goal will be to clean the fuel system. I’d wait until the tank is low (1/8 tank or so), add a whole 16 oz can of Sea Foam High Mileage, and then drive it until almost empty (20 miles minimum ideally, or as far as you’re comfortable driving on a low tank. After that, refill with fresh fuel. If you want, you can repeat that same treatment when the tank gets down to 1/8 tank again. That will clean out fuel residues and deposits that formed when the truck was sitting.

If you want to be extra cautious, you could drain the old gas out of the fuel tank, add 1/8 tank of fresh gas, and then add the High Mileage and drive it until almost empty.

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

Thanks for the question, Kim. Yes, you can absolutely use Sea Foam Motor Treatment in your 2024 Toyota RAV4 Hybrid. Just follow the directions on the can.

Even though your RAV4 has less than 11,000 miles, fuel residues and deposits begin forming during normal use of any engine. Many people use Sea Foam as preventative maintenance to keep the fuel system clean and help prevent those deposits from building up over time.

Here’s what I’d do to get the most cleaning power out of a can of Sea Foam:

• Wait until the tank is low (about 1/4 tank or less)
• Add a full 16 oz can of Sea Foam
• Drive at least 10-20 miles (or until nearly empty) before refueling

The high concentration works much better and faster than adding it to a full tank.

For a newer vehicle like yours, one treatment every 3,000-5,000 miles or once or twice a year is a great preventative maintenance routine.

Hi Harry ,

Thanks for the question! Yes, you can use Sea Foam in a Stihl chainsaw, and any other gas or diesel engine.

For preventative maintenance, add 1 ounce of Sea Foam per gallon of fuel to every tank. That will keep fuel from degrading and prevent gum and varnish from forming. For cleaning the entire fuel system, use a high concentration of Sea Foam – up to a 1:2 ratio of Sea Foam to gas. If you’re experiencing problems with it (or want to just do a really good cleaning), I’d add 4 oz of Sea Foam to 8 oz of gasoline and run it for about ten minutes, shut it off, let it sit overnight, and then run it for a few minutes again the next day. That will do a great job cleaning up any fuel gum or varnish that’s formed anywhere in the fuel system. Gum and varnish is a very common cause of problems in a small engine like that.
