Motor Oil ??

0w-40 mobil one and be done

not in an M50. 10W30 until your VANOS unit starts making noise (usually higher mileage) then 15w50 once you hear the tapping from it. I personally use Mobil1 and Amsoil.

this weekend, i'll be installing the german castrol 0w30 oil into my m50 (aka jesus among synthetics under $6USD) and see how she fares. the car will be used as a delivery vehicle starting next week, so we'll see how long it holds up under severe start/stop cycles before it breaks down according to the Roopnarine method for viscosity determination . multiple tests at bobistheoilguy put new GC 0w30 at a viscosity of 12.2 at 100C, which is just on the borderline for a 30/40 weight (40 starts at 13). m1 0w40 tests between 13.2 and 13.5, so i doubt there's going to be that much difference, especially since both are very good oils. i know that i could certainly stand to stomach a few extra mpg now, so i wont sweat the fact that its a 30 wt. (i'm sure i'm not the only m50 owner in a warm climate running a 30wt).

boo! u are teh suck! i was actually gonna ask if i could use SAE 40 wt in it if it was going to be used for delivery, but then i realised that the only benefit i'd see in that situation is if it were a taxi cab or police car. this car will be started/stopped too much for that. the bentley AND bmw certainly says i can use that thickness in the climate i live in...... i wanna see what kind of benefit green motor oil will provide me with.
