Can Sea Foam Motor Treatment be used in a 2014 VW Passat Diesel Engine? [SOLVED]

Thanks for the question!

Yes, Sea Foam Motor Treatment is safe and effective in the fuel tank and oil of a diesel engine, including your 2014 VW Passat.

In fuel, it cleans diesel fuel injectors and chamber areas. By adding Sea Foam to the fuel tank or primary fuel filter, it restores diesel injector spray patterns, removes soot and clears carbon deposits from injector nozzles, enhancing overall engine performance. Add at least 1 ounce of Sea Foam per gallon of fuel.

In oil, Sea Foam Motor Treatment will help dissolve petroleum deposits and contamination that forms in crankcases. It aids in cleaning crucial components such as lifters, tensioners and control rings, restoring optimal flow and lubricity to restricted oil passages. Treatment also helps mitigate injector stiction, contributing to smoother engine operation and prolonged performance. Add 1 ounce per quart of oil.
