I, like everyone else, only have 5w-30 in the vw507.00
VW 507 requires not only a Low-SAPS Formulation, (SAPS refers to sulfated ash, phosphorus and sulfur), but also a lower viscosity than was appropriate before with the prior 50x series.
Thanks. I know they're anal about using oil that meets 507.00.
I'll be in touch... going to change the oil in this thing around the 5k mark and then will let the dealer handle it after that since scheduled maint is included.
