Yes. Regular 0w30 may not have the HTHS that 502.00 and 504.00 requires (3.5 MPa minimum), so it will trade off engine wear for some improved fuel economy.I’ve decided to go with 0w 30 synthetic oil. Mobil 1 makes one for a reasonable price in a 5 qt jug. However, I don’t see anywhere that it has VW 504 00 certification/standard. I’ve used Mobil 1 for years. It relatively cheap compared to Motul. Does it matter if it‘s not officially VW 504 00?
