摘要

Given all the current activity in developing new engine oils, this is a good time to look at the differences in oil appetites between heavy-duty trucks and light-duty vehicles. Many of you in the business know that there are significant issues around both types, and that two new categories, PC-11 and GF-6, will be introducing some new wrinkles in the engine oil story. All engine oils have four essential purposes: to lubricate, seal, cool and clean. They accomplish their mission through a carefully crafted combination of base oils, viscosity index (V.I.) improvers and performance additives. The selection and proportions of these ingredients vary depending on the applica- tion in which the oil is going to be used.
