Just started adding the mmo to both car's, the Alero get's up to 5% ethanol gas so figured I would try this out as I read lot's of good thing's about in on BITOG. I added just 2 oz. and am hoping it does some good stuff, I will report back if I notice any change in my vehicles with it, does anybody else have any good or bad thing's to say about the use of mmo in their vehicles? Oil or fuel related? I Will also be adding a little to my oil 200 miles before changing it.
