Just wondered if it is true that the DLRB engine that uses the Buddack cyle, has to use engine oil meeting VW508?
I looked in owners manual and no mention of this- it specs VW502/504.
I looked at this old press relase too;
Which seems to suggest that VW508 oils are designed for fuel efficiency - and then there are posts on "bob is the oil guy" referencing VW comments about damage to the oil pumps being caused by non 0w20 oils being used.
Anyone had any info on dealers about this?
