I would try to search, but I can't think of how to search for it here. Can you list the different oils that you feel are high quality? Not necassarily the weights, but the brand and line of product. I would like something to refer to when I am shopping for a new oil before the scheduled change. I am looking for: Auto engine oil ATF Gear oil PS fluid Brake fluid Currently, I run Mobil 1 because I am under the impression that it is of decent quality, and available at most auto parts stores. Availability is pretty important considering what kind of vehicles I drive.
