In Reply to: its 5w30 at the dealer, 3.50 quart. Castrol part posted by Bill R. on November 22, 2000 at 17:44:59:
I was shopping for oil and came across Penzoil Synthetic... and was surprised to see 5W50 rating on it. Just to let you know that you got an alternative to the $9 a quart Castrol 5W50 synthetic oil found at your local BMW dealer.
For those of us with the V8... that is $36 saving on an oil change... really fancy dinner for two.
