What's the difference between the two products in this pack?

Motor Treatment is a pour-in additive for your fuel tank or oil crankcase that cleans fuel and oil systems, while Sea Foam Spray is applied through the air intake to clean carbon deposits from intake valves and the upper engine.

How do I use Sea Foam Spray?

Unlike tank additives, Sea Foam Spray works through a gasoline engine’s air intake to dissolve harmful deposits and residue buildup from intake runners, intake valves, and combustion chamber areas. Help your engine run cleaner!

Can I use both products together, or should I space them out?

They can be used as part of the same maintenance session. Motor Treatment in your fuel/oil, and Spray through the intake since they target different parts of the engine.

Is this combo safe for direct injection (GDI) engines?

Yes, Sea Foam Spray is especially useful for GDI engines, which are prone to intake valve carbon buildup that fuel-tank additives alone can't clean. Sea Foam Motor Treatment can be used in any engine, including GDI engines.

Will I see smoke from the exhaust when using the Spray?

The smoke people talk about is vaporized oil from the Sea Foam Spray formulation. Whether you see the vapor makes no difference in how it cleans.
