Title: Less metal wear in oil sample
Review: My 2002 Olds ECOTEC 2.2 gets better mileage and less piston ring wear metals in the oil samples. My 2008 Taurus X 3.5 V6 gets about the same mileage however engine knock under stress is gone on the cheap gas. I believe this product makes the 87 octane gas more stable and decreases your piston ring wear. Gas mileage improvement is more noticeable in my smaller higher revving engine. As for injector and fuel pump life extension, I'll have to see as I plan to run these cars into the ground.
