Here`s my 2nd UOA. Oil was Mobil 1 10W40 High Mileage. Interval was 3000 miles (give or take a few). Mostly daily city driving,a few short highway runs here and there.
My 1st UOA was Royal Purple 20W50 (the first column in this UOA) w/Wix filter. This current one was with a Fram TG. How would you compare this UOA to my previous? Do you feel the 1ppm lower iron and aluminum with the RP is worth the cost over the M1?
