Apparently what the VW/Audi dealerships use is the Edge Prof 5w-40. However, when I compare the tech sheets, all the physical properties and all the mfg approvals are identical to the regular Edge 5w-40. The only difference appears to be that the Prof version is available in bulk/55 gal drums.
Or are there some additional differences that I missed?
