I remember DrT mentioning that a few weeks ago that the BMW 0w40 might possibly be the Formula R 0w40, however it's also $13 to $14 per liter too, versus $6.66 for GC or $7 and change for M1 0w40, so that's quite a large jump!quote:

Losiho and Patman, BMW Canada is using Castrol Formula RS 0W-40 to service some of their newer vehicles. Several months ago I called the two BMW dealers in the Las Vegas area and both dealers had never heard of Castrol Formula RS 0W-40 synthetic oil so as far as I know it is not being used in the USA.
