What Oil do you use?

[markseven]

Shell or Chevron 20w50, standard oil.

Matt, isn't that a little thick?

I'm running Castrol Synthetic 10w40.

royal purple 5w30

[D-rock]

mobile 15w50 anyone? :/

[BenM]

^yes

S50 E34 Touring - Mobil 1 15W50 Red Top in the spring/summer/fall, Mobil 1 10W40 High Mileage in the winter

M50TU E30 - Mobil 1 15W50 Red Top all year round (garaged during the winter)

Here is an oil chart in the E34 section from bimmerforums. Not sure why you guys in the warmer climates would use anything less than 15W50.

Mobil Clean 5,000 (5k miles) 10w30... I'm afraid it will leak somewhere if I start using Mobil 1. I generally use Mobil 1 in everything, parent's car's and all my past vehicles. Will probably switch to synthetic once I go turbo
