Any recommendations for what oil is best for the S54 (Z4M and E46 M3) engine?
I was planning on using the standard Catrol Edge 10W60 stuff, but interested in any other suggestions. The car may see 1 or 2 track sessions next year, but it will only do 3000 miles between changes.
Hi Do NOT use anything other than Castrol 10/60, My E46 M3 SMG has done 141,000 miles on it and it runs like new still, I do change Oil and filter every 15,000 miles its worth the cost.
Definitely just use Edge 10W60 for M engines. I usually change the oil every 7-7.5k miles as leaving it in for 2 years or 15k miles doesn't seem appropriate.
