Yes, you can use Sea Foam Motor Treatment in A 2013 KIA Sorento. It’s compatible with that model. 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.

You could also try High Mileage Motor Treatment. It’s made specifically for stubborn residues and deposits in higher-mileage vehicles. It’s a great cleaner!

Thanks for the question!

Here’s what I’d do: your first goal will be to clean up and fuel gum and varnish that formed while the scooter was sitting (or has built up over the years). Add 8 oz of Sea Foam and 16 oz of gas to the tank. Start it up, let it run for 10-15 minutes, and let it sit overnight. Start it up the next day and let it run a while. After that, run it as normal and add 1 oz of Sea Foam per gallon of fuel to prevent fuel residues and deposits from forming and fuel from degrading.

As far as the oil goes, I’d change it and then add 1 oz of Sea Foam per quart of oil. That will clean up oil residues and prevent them from forming.

Hey Thomas,

Thanks for the question! Yes, it can unclog a clogged injector. I’d recommend High Mileage Motor Treatment in the gray can. You can get it at any auto parts store. Here’s what I’d do: 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.

Thanks for the question, Charles.

What you’re describing is very common with small engines that have been sitting. In most cases, this happens because fuel gum and varnish formed in the carburetor while the fuel sat. That residue restricts fuel flow and causes engine problems.

If fuel varnish is the issue, Sea Foam can help clean it up. The best way to do that is to use a high concentration of Sea Foam Motor Treatment (or High Mileage) so it can clean the gum and varnish quickly and effectively. Here’s what I’d do:

• Drain the fuel

• Add a high concentration of Sea Foam and fresh gas (up to about a 2:1 ratio of gas to Sea Foam)

• Run the engine as long as you can to pull the treated fuel into the carburetor. If it won’t stay running, prime it or pull the starter rope several times to help draw the treated fuel into the system

• Shut it off and let it sit overnight

• Start it up the next day and let it run for a while

Once it’s running normally again, you can switch to adding 2 ounces of Sea Foam per gallon of fuel to keep the fuel system clean and help prevent this from happening again.
