Received a short newsletter in the mail yesterday from Blackstone Laboratories. Here are a few quotes "It doesn't really matter what brand of oil you use. We always do recommend using an oil grade recommended for your engine by the manufacturer and a brand that fits your budget. The grade of oil is much more important to performance then the brand of oil" Further " The oils that you find at any mass retailer are actually name brand oils, but with the store's label on it" The only difference between the "generic" brand and the name brand oil is the name on the bottle and about 50 cents per quart" So, to some degree this appears to go against what is spoken by many members of this board. They recommend using analysis to test which brand is going to perform better in your car also. I don't understand how they can say that the grade is more important then the brand and then recommend analysis to see which "BRAND" performs better in your engine.
