10w-40 mobil1 high mileage

[Thrizzle]

mobil1 0w-40 in my 116k s52.

Have ran 0w-40 in my other s52 from 120k to 150k with no problems.

It also depends on the climate you live in too. Someone that lives Alaska should not be using the same viscosity oil that someone in Arizona is using.

FYI
(10w30)
10w= the viscosity of the oil measured at 0 deg
"w" meaning winter grade
30= the viscosity of an oil when measured at 212 deg

Viscosity is resistance to flow.
An oil with high viscosity will be thicker than an oil with low viscosity.

You should all use Castrol since thats what BMW uses.

[Kumi]

Castrol GTX 20w50 past 2 E30s have ran great, and reliable for about 150k miles on the first one, and about 90k miles on the current one.

[trackjunkie21]

15w-50 fully synthetic in the summer and 5w-30 in the winter, also fully synthetic.

[ForcedFirebird]

You should be running full synthetic in your 24v VANOS motors.

Period.

[lolcantturn]

Shell Rotella

Since we're on the topic, how often should one change the oil on these motors? I feel like I've been changing mine every 3000 miles lol.

[drumad]

German Castrol. 0W30.

Mmm green oil.

rotella 20w50 in summer and 0w0 water in winter
