Do not use Sea Foam Spray on a turbo-diesel engine (TDI)

Thanks for the question, Harry.

We do not recommend using Sea Foam Spray in a diesel. Introducing a second source of fuel through the intake can cause a diesel to “runaway” and damage the engine – very dangerous! Look up a few videos on “diesel runaway” on YouTube.

As far as our product line goes, Sea Foam Motor Treatment is the most popular choice for adding to fuel or oil in diesel engines.

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