Yea I guess the track use point makes some sense, but I don't really see how the change interval can be a reason seeing as plenty of 0/5w-30/40 oils can do 15k OCI.
BMW not doing 15k changes anymore? |
The 10w60 shears down to a 30-40 weight towards the end of the 15k service interval. BMW has moved to a 10k mile interval on most cars now.
Another reason some like to run the 0w40 is to reduce wear on the rod bearings. The original rod bearings have a very tight clearance and some feel the 0w40 does a better job squeezing in and lubricating the bearings.
