Does anyone out there know of a synthetic motor oil brand BESIDES what Audi or VW wants to sell us at their dealers that matches what my '07 Audi A3 owner's manual specifies as the "Audi oil standard VW 502 00" (p.286)? I went to a chain auto repair store with quite a selection of brands and viscosities. NONE of those brands included meeting this VW 502 00 standard. Many did include standards for the most popular cars sold in the U.S., e.g. Toyota, GM, Ford, Chrysler. I wonder if the last three digits of the VW 502 00 is code that the oil be able to meete the high temperatures for engines with 200 or more horsepower? I bought Pennzoil's best synthetic 5W 30 since this new parts store didn't have the desired SAE 5W 40, which is Audi's first choice in viscosity AS LONG AS IT MET their "VW 502 00" standard."
Are there any code talkers out there?
