Here is how to use it

ADDED TO ENGINE OIL

Use Marvel Mystery Oil in the crankcase to benefit oil. At your next oil change, replace 20% of your engine oil (traditional or synthetic) with Marvel Mystery Oil. For example, if your engine has a 5-quart oil capacity, replace one of the quarts with a quart of Marvel Mystery Oil. Repeat at every oil change for optimal performance.

ADDED TO FUEL

At every fill-up add 4 ounces of Marvel Mystery Oil to every 10 gallons of gas or diesel. An average passenger car tank is 15 gallons, so you would add 6 ounces at every fill-up. Regular use can lead to improved fuel economy.
