When ConocoPhillips announced their new (then) SM/GF-4 5W-20, 5W-30, and 10W-30 synthetic blend entry-level motor oils a year ago November (2004), their press releases for the new Conoco, Phillips, 76, and Kendall brands each stated more than 50% synthetic content. Undoubtedly that does refer to Group III, but take with a grain of salt the careless assertions by someone that the content is "a small portion". The remaining base oil content is solidly Group II (except for perhaps a minimal amount of Group I as the additive package carrier oil). ConocoPhillips got a running jump on where "conventional" motor oils are headed in the not-so-distant future. That company is also the contract supplier to Ford, U.S. for Motorcraft Premium Synthetic Blend motor oils, and by most accounts is very close to, if not identical, to the ConocoPhillips "house" brands.
