I've run mobil 1 in my escape in the past for 10k mile oci's. currently i'm using some napa syn i bought cheap for 7500 miles. I recently picked up some qsud at a decent price. How long has anyone run this? is it a 10k oil? or would 7500 be it?

No i must admit i never did, the oil looked good( i know, i know) so i ran it that long. Just not sure if qsud is on the same level as m1. I am going to get a uoa on this run of napa syn at 7500.
Many say that QSUD is a great oil. A "sleeper" in all the other options that include Mobil 1, Valvoline SynPower, Pennzoil Platinum, Castrol Syntec, etc.
Your UOA of Napa synthetic will tell you a lot. I have to believe that if it produces a good UOA after 7,500 QSUD will do just as well. To know for sure, you'll have to try it and get a UOA.

Its made my Ashland (valvoline) but it doesnt have as strong as an Ad pack as synpower
