2007 E92 335D Oil
I am looking to provide my own oil for a service that is due, what is it i need to look for?
Does it need to be the Castrol Edge 0w30 Professional? It's about £85 for 8 litres on ebay, making it £10.60 a litre vs the dealers £18+VAT per litre.
IF not, what other oil should I get? I have a warranty that I want to keep. On my E46 i just got Mobile 1 from costco that was LL01 and the dealers were happy to use that.
PS How leniant are BMW on their service schedule? IE if I go over the count down by a few hundred miles will it invalidate the warranty?
