SUMMARY
Sea Foam Spray is a blend of cleaning and lubricating petroleum ingredients that can be used SAFELY in all types of 2 and 4 stroke gasoline engines. Especially important for modern GDI engines, it cleans critical upper engine areas where fuel cleaners can’t reach.
Apply Sea Foam Spray through fuel injection throttle bodies to clean harmful engine deposits from intake valves and combustion chamber areas. Use Sea Foam Spray to fog engines and coat spark plug cavities to protect your engine during storage.
Sea Foam Spray does NOT contain harsh detergent or abrasive chemicals that can harm your engine or fuel system components. Help your engine run cleaner and last longer!

RELATED QUESTIONS
What is the difference between Sea Foam and Sea Foam Spray?
Thanks for the question, Shahid! Here’s the difference:
Sea Foam Motor Treatment:
- How to use it: pour it in your fuel tank or oil crankcase
- What you can use it in: any gas or diesel engine. It’s safe and effective in any kind of gas or diesel fuel, and any kind of motor oil.
- What it does: cleans fuel and oil residues to help your engine run cleaner, run better, and last longer
Sea Foam Spray:
- How to use it: apply it through a gas throttle body or carburetor
- What you can use it in: gas engines only. Particularly useful in gasoline direct injection engines. NOT for use in diesel.
- What it does: Sea Foam Spray is an aerosol version of Sea Foam Motor Treatment. Sea Foam Spray works through a gas engine’s upper air intake to dissolve harmful deposits and residue buildup from intake runners, intake valves, and combustion chamber areas. It’s especially helpful for cleaning intake valves in gasoline direct injection engines (GDI).
In short, both products will clean critical engine areas to help your engine run better and last longer.
Can you run Sea Foam through a vacuum port?
Thanks for the question, Ron! We do not recommend running Sea Foam Motor Treatment through a vacuum line due to the risk of hydrolocking the engine.
Instead, use Sea Foam Spray through the air intake. It’s easier, safer, and it disburses evenly to all cylinders.
Is Sea Foam and Sea Foam Spray safe in turbo charged gas engines?
Thanks for the question! Yes, any Sea Foam product that’s labeled for a gasoline engine is also safe for a turbo.
Sea Foam Spray is safe and effective in a turbo. We get asked about that a lot! Here’s a video with step by step instructions.

Can Deep Creep be used for carbon cleaning an engine?
Can I use the Sea Foam Spray in my gas tank?
Thanks for the question!
First, you can use Sea Foam Spray in your gas tank. It will act similarly to pouring Sea Foam in your gas tank and won’t hurt anything.
I’d apply the Sea Foam Spray through your air intake, though, as that is a much more cost effective way to use it. It will clean intake valve areas that a fuel additive in the gas tank can’t reach.
If you’d still like to use it in the gas tank, it’s safe and will work similarly to Sea Foam Motor Treatment.
