Castrol Edge 10w60 mention " Di-ester base added for extra wear protection'. Is this the Ester Group 5 component of the engine oil ? First time i see them really mention any type of base.

Too much seal swell, potentially. If they do their homework it should be OK but still would make me uneasy. Polyol ester is much better all the way around except for cost.
Hi,
on a recent trip to Europe (Germany in particular) I found that this lubricant has a very large following amongst racers - especially Audi, BMW and older air cooled Porsche Teams and Owners
Yes this is what others have said. SO previous have mentioned di-ester to be a poor version of ester, but in another post on hear i have read that Motul 300V is also Di-ester. It must still have its benefits.
