I have a friend who is a refinery engineer. He says that the difference is in the additives that different companies add to their oil. Switching to different brands means different additives, and that seals may swell or shrink due to the change in the additives. His advice is to pick a brand and stick with it. On another note, my wife's Suburban was using a quart every 3 thousand miles when it was brand new. Dealer said that was within specs. We switched to Mobil One and that cured the problem. I've gone to synthetics in all my cars now, but use Chevron RPM Delo in the tractors.
