How to use Sea Foam in oil

Thanks for the question, Larry. I’d simply add a full can (20 oz) to every tank. That amount will work very well to keep your outboard running clean and your fuel stabilized. At a minimum, use 1 oz of Marine PRO for every 1.5 gallons of fuel.

If you want to run a cleaning dosage every once in a while, add a full can to a low tank (about 1-2 gallons) and run it until almost empty before refueling.

Rob – that’s a good question!

Adding Sea Foam to fuel would be a great way to clean the engine and overcome any performance problems related to fuel (which is a very common cause).

It’s made with 100% safe petroleum cleaning and lubricating ingredients, so it’s safe to use in any engine, including an 18 year old Corolla. It doesn’t have harsh chemicals, so no worries about damaging anything, regardless of age.

Our recommendation:

Add a full can of Sea Foam Motor Treatment to a low tank of fuel (1/8 tank or so). Drive it at least 20 miles before refueling to give the high concentration of Sea Foam a chance to work through the system. That’s one of the best ways to use a can of Sea Foam!

Thanks for the question and hope that helps!

Thanks for the question, Joe. No, it will not harm turbos. Both Sea Foam Motor Treatment and Sea Foam Spray are safe in any gasoline engine. Sea Foam and Sea Foam Spray are made from the same raw petroleum material as gasoline and motor oil. There’s nothing about it that could cause harm to a fuel system or engine components, so go ahead and give it a try!

Here’s a great step-by-step video about using Sea Foam Spray in a turbo.

Hey Perry – thanks for the question!

We get asked about sensors and new vehicles a lot. Sea Foam is made from 100% safe petroleum ingredients that can’t harm sensors. Additionally, it won’t interfere with readings, so if you want to add it in a new vehicle, go ahead and use it without worry.

Sea Foam Marine PRO will work great to clean injectors on a 40hp Mercury!

Here’s the best way to do it:

Add a full can of Marine PRO to a low tank of fuel (1/4 tank or so). Then, operate the engine for at least 20 minutes before adding more fuel (just don’t run out!). The high cleaning concentration is the fastest and most efficient way to clean injectors with Marine PRO.
