http://www.pzlqs.com/Tech/Pdsheet/DomesticMarketing/EngineOils/Pdf/HighMileageVehicle.pdf Look at the HT/HS numbers on the 10w40. They are as high or higher than some group III, 10w40 synthetics.Viscosity at 100 Degrees C looks interesting. Even the 30 weights look good. I believe they use "purebase" as their base oil, a group II+. For someone looking to control oil use and/or high h.p.applications, I think it has merit. $2.14 a qt. at Walley World. comments?

Pennzoil makes some great oil, that's for sure! Here in western Washington it rarely goes below 20 degrees F, so we can use 15-40 longlife year round! I consider that to be one of the the best mineral oils you can buy!
