Hi, I’m new to this forum and have a question about what I think is a new oil that is out. The oil is Delo 5W-40 synthetic. http://library.cbest.chevron.com/lubes/compprd9.nsf/0/d19c4ebb6aed04238825625a006db4bd?OpenDocument . My question is does any one know how this oil compares with Mobil Delvac 1 5W-40 synthetic. Thanks to all.
