Hello fello bitog's. Please humour me.
I'm currently running Penrite HPR5 which is a group III. What are your thoughts on this opposed to Castrol Edge 5w-30 which is also also MB229.5 approved and A3/B4 approved. The Edge boasts Titanium FST. Is this anything? Is it also a group III?
Assuming both are as easy to source, the same price and being used in a Merc E55, what's the difference?
Cheers.
