In Reply to: What Oil Weights to use on E34? posted by Wild Bill on July 30, 2001 at 12:54:54:
The biggest criteria is what is suitable for use in winter in your area. I definitely know I will need a 10W in my area Northeast... and the thing is every oil at the store is in 10W30 or lower... and I was thinking of 10W40 because of the summer condition. Since synthetic is far superior in cold climate, I don't know about if 15W50 is suitable...
Anyway, right now I am really scratching my head about which brand to use... Mobil 1 or Amsoil... Amsoil seem to be better according to their reports but I would like to see independent reports also. Any info would be greatly appreciated.
