My 5 quart jug of Pennzoil Platinum says "...no leading synthetic motor oil provides better wear protection**"
then under the ** (two stars) it says "as measured ... using SAE 5W-50"
I have never seen 5W-50 Pennzoil. Why claim your 5W-50 is better than "leading synthetic" oils when the oil they used does not exist in the general supply chain. It's a useless claim. I thought Mobil-1 5w-50 was some hot stuff according to some UOA on race motors.
