oil is pretty much oil.. 91 taurus sho, 180,000 miles on quaker state dino oil, regular change interval. engine out lasted the rest of the car... it was the only thing standing at the end, on top of that, this was before internet, FRAM filters, the cheap stuff that no one would even use now..

i never used m1 till i got my honda and then tsx.. didn't make a difference, as long as you have good oil change intervals
