SeaFoam and Marvels Mystery Oil are acceptable substitutes. And can be found at just about any auto parts store.

We cant buy GM Top End cleaner here in California either.Edited by: Low Saturn

Are those types of cleaners used the same way? Pour through spark plugs let sit for min 8 hours...drian,oil change/plugs change?

Yep. Exactly.

But I usually let it sit longer. Usually over night.
