Thanks for the question, Richard! Thinking about the best way to use High Mileage to get the most cleaning power out of it, here’s what I would do:

Wait until the tank is low (1/4 -1/8 tank), like you described. Then, add the whole 16 oz can, and drive for at least 10-20 miles before refueling. The high concentration works very well to clean fuel residues and deposits. As far as fuel goes, use whatever you’d use normally.  Add it to fuel like this every 3,000 miles or once a year.

Hope that helps and let me know if you have any questions!

If the oil burning is caused by oil residues and deposits, Sea Foam will help reduce it.

Adding 1 oz of High Mileage (what I would use) per quart of oil during every oil interval will progressively help to reliquefy the heavier oil residue that’s plugging up your engine’s oil flow. If high miles, you may also be dealing with worn compression rings that would allow oil to end up in the combustion chambers. In any case, keep adding High Mileage to your oil each interval and pay attention to oil consumption.

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

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!

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.
