How can you deny such a legacy! I use this as well as a little Prolube and top it off with some STP High Mileage Oil Treatment to substitute the last quart on every oil change!

The synthetic version of the superior Marvel Mystery Oil cleans the engine even better than the original formula, but it can only be used in the crankcase. I've been using the original formula for 20 years now, and this removes even more carbon and grime with half the amount. One of the best engine additives on the market. In this day and age, oil, even some of the best, is not enough.

Did it work well?

How can you know if it works? How do you know what would have happened if you hadn't used it? Life is full of uncertainty ...
