So I've done this once before and felt inclined to create an updated comparison chart. I left Castrol off the list because their PDSs are useless and I wasn't going to waste the time entering the data. Eventually I will be adding some of the other brands but for now this is a good start. If anybody else would like to create a spreadsheet with other brands and add it to the thread, feel free to do so. Hopefully this makes some of your oil critiquing and buying decisions a little easier, enjoy!
