Marvel Mystery Oil

Well said.

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.

Looks primarily like a solvent. Naptha + Mineral sprits.

Since I'm fairly convinced the bottom oil ring design is responsible for units that burn oil, it's equally plausible that this solvent "frees" up sticky oil-scraper rings to perform their job [correctly] again.

Risky? IDK.

I'm not sure I'd use it continuously...like the website implies.

Sounds more like "Engine Flush" which is used to clean just prior to an oil change.

Well! That's why Mobil 1 invented their high mileage version (75K+). I had leaks too until I switched to this version that contains a seal improving ingredient. This type of seal technology is available by itself, but Mobil 1 does it in one convenient package. I've noticed no leaking since introducing Marvel Mystery. I'm now at 750 miles and am using less than half the oil I'd expect. I'll keep you posted.

Hey blacksambo, Did this do the trick? I have a 2000 with 68000 mi on it and it started using more oil. But it does not use the same amount everytime. sometimes it uses a quart in 300mi and then the next time it will go 500 mi before I loose any oil. I want to give this a shot seeing how it is just starting to use oil.

My main skepticism is there are no directions or claims how it works. Add to oil or gas. Well do you add for a few miles before oil change or add it afterwards and run it the whole time. Depending on strength etc a short time would not be long enough or at high strength would eat through everything
