Mineral Oil - Improve Gas mileage?

piddlerdad3
16 years ago

I had someone recommend to me that I should try putting a few ounces of pure mineral oil in my gas tank and in my crankcase in order to boost gas mileage.

Is this a reliable and safe thing to do for gasoline vehicles? I would rather not have any negative consequences to my engine.

Thanks, dennis
