Thanks for the question, Mark. Yes, you can use Sea Foam in both the fuel and the oil in your Kia Spectra.

In fuel, I’d recommend waiting until the tank is low, about 1/4 tank or less. Then, add a full 16 oz can and drive at least 10–20 miles before refueling. The higher concentration works much better and faster to clean fuel gum, varnish, and other deposits.

In oil, use 1 oz of Sea Foam per quart of oil, added 100–300 miles before your next oil change.

High Mileage Motor Treatment is also a great option as it’s a great cleaner for older vehicles.

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

Best,

Hey Lonzo,

Thanks for the question. Yes, you can use High Mileage for your 2024 Civic. High Mileage is a great cleaner – it’s formulated to clean stubborn deposits and residues after years of buildup. But you can absolutely use it in a lower mileage vehicle too. It’ll do a good job cleaning up the fuel system.

Here’s what I’d do:

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

The high concentration works much better and faster to clean fuel residues and deposits than adding the same amount to a full tank.

Thanks for the question, Ron.

Yes, you can use Sea Foam Motor Treatment in the oil of your 2008 Kawasaki Vulcan 1600 Nomad with a wet clutch. Sea Foam is petroleum-based and can be used in for wet clutch oil systems when used at the recommended ratio. Here’s an article on it on our site: https://seafoamworks.com/using-sea-foam-in-a-wet-clutch-oil-system/

Add 1 ounce of Sea Foam per quart of oil, and do not exceed that amount. Then ride normally for about 100–300 miles before changing the oil.

Sea Foam works to reliquefy oil residues and deposits in the crankcase. In a wet clutch system, that can help clean sticky oil residues from the clutch components and oil passages. If deposits are contributing to clutch sticking or poor engagement, cleaning them up may help the clutch operate more smoothly.

There’s nothing special you need to do beyond using the correct ratio and changing the oil afterward. I would not add extra Sea Foam in an attempt to clean the clutch faster—a normal 1 oz per quart treatment is plenty.

Of course, Sea Foam won’t repair worn or mechanically damaged clutch components, but if oil residue or deposits are contributing to the problem, it can definitely help clean them up.

Thanks for the question, Allan!

For a 5-quart oil capacity, use 5 ounces of Sea Foam Motor Treatment. Use 1 ounce per quart of oil and do not exceed that ratio.

Here’s what I’d do:

• Add 5 ounces of Sea Foam to the crankcase.
• Drive normally for 100–300 miles before your next oil change.
• Then change the oil and filter. The Sea Foam works to reliquefy old oil residues and deposits so they can drain away with the old oil.

For sludge and oil residue buildup, it’s better to repeat the treatment over several oil-change intervals. Do not exceed 1 ounce of Sea Foam per quart of oil. Cleaning gradually gives the reliquefied deposits a chance to drain away with each oil change.
