Really interesting stuff!
When added to engine oil, Marvel reduces and prevents valve sticking and clatter by breaking down harmful deposits of carbon and sludge.
Marvel will prevent sludge build-up from occurring in new engines and removes sludge from older engines
1) Couldn't this potentially cause oil leaks at the rubber gaskets, same as many say happens when they switch to synthetic? Because it's thought it cleans off the buildup that was actually sealing a gasket.
I didn't have any leaks when I switched to synth, don't want to test fate
2) "Jets"..they spray fuel or oil into cylinder?
3) Is this much different than Seafoam or Lucas and what they claim with those products? Although I know you only use Seafoam periodically, not at every fill up, and you don't leave it in the oil long term either IIRC when I used it.
