[QUOTE="CATDiezel, post: 1089894, member: 4387"] As one commented. They rebuild every pass. The high load of a 800 hp diesel compared to a 8000hp small block is a bit different. They are not worried about piston jets cooling the cylinder walls either. AND there clearance tolerances are alittle bigger to accommodate for such high weight oil and the extreme heat they run. Where we are worried about 250*F. They are seeing in excess of 350*F fast and In a hurry. So there oil is getting close to a flash point if they don't knock it off soon. 70w oil at 350-400*F Flows like water. The engine design from a drag car to this 6.7L isn't a fair comparison at all.
