>>>Lotus specifies Castrol RS 10W-60, which is not available at BMW dealers. I posted more info in the "official track oil" thread<<<

There are some differences of opinion on that oil amongst BMW enthusiasts. Some say the two versions are...the same... and it's just a marketing thing. Some say that one superceded the other. And others say that they are completely different.

Of the three oils Lotus has suggested, only one is easy to find. The Mobil 1 15W50 is easy to find at many auto parts stores. Some dealers are not even using the 5W-40 Texaco street oil.
