Hey guys, I have an Z4M for couple of months. I would like to ask what kind of oil you put in your M engine? I saw on the engine recommends Castrol 10W-60 but I couldn't find 10W-60 in auto parts store? Do I have to use 10W-60 or I can use lower? If I have to, do they have it at the dealer?

Read page 30 of your Supplementary Owner's Manual for BMW Z4 M Roadster/Z4 M Coupe. Preferred viscosity is 10W-60 and Castrol TWS, BMW P/N 07 51 0 009 420, is the only 10W-60 oil available in the US and is only sold by BMW dealers with an MSRP of $9.45 per liter.
