Maxlife has a good slug of calcium. About 0.26 percent I think. But what does the calcium do?
Also, does anybody know what group base oil Maxlife has? I got nowhere with their phone reps.
I checked out the tech data sheets on several high mileage oils and Maxlife appears to be unique among them in that it is not thinker than regular oil at 100C, but the other HMs are runing 1 to 2 higher on 100C viscosity. Not sure what it means though, but certainly they are not giving you just a thicker oil, unless the base oil is thicker. If you look at the stated flash point for 10w40 Maxlife (242 C) it is right up there with regular 20w40 oils. The only way they could get that kind of a flash point on it seems to me would be to have a thicker base oil at the high end of a 10w range, maybe close to a 15w.
