QUOTE......Essolube Xd3 15w40 (EXXON for you) and Shell's rotella t are designed/formulated for either gas or diesel severe duty , high friction type applications.(flat tappet engines) it does have P and Zn in the add pack along with a bunch of other additives. If you want a spotless engine(internally) being highly protected from wear then use it. The oil certainly doesn't know a lycoming from a cummings. It just cleans and protects. (way better than "aviation" oil). Sorry that the facts. 37 years for Imperial oil looking inside hundreds of disassembled test engines.
