Define "best."
Also, the OP's car is under warranty.
I would like to know that too.
I was personally involved in testing of one oil (not on sale in the U.S.). Approval from VW for 504.00/507.00 was like 3000 euros. So my question is: Why Redline is not getting those approvals.
Amsoil got MB, BMW and probably will soon get VW.
So how come that "best" oil does not have any approval?
3000 euro is only the approval admin charge! Getting the 504 507 specification on a formulation requires many engine tests and will often cost over $3m as it requires lots of tests and they are bloody difficult so need several attempts.
3000 euros is what VW charges.
How much you need to invest in the development of certain oil is another thing. 3m, 2m, 1m, 500K, 100K, depends on the oil manufacturer. I can tell you that if this manufacturer invested 3m, they would be long gone bankrupt.
If Redline has an oil that they say meets VW requirements, than there is no reason to send it to VW and get that approval.
