Engine oil Castrol or OEM BMW

I only had two oil changes and stuck with the OEM Castrol 5w40 :thumbup:

Castro 10- 60 Audi uses it in R8 GT which is NA and not subject to extra thermal loaf of TC. Live in South Florida so cold starts not an issue and Sebring in August is HOT. Also run 50 % VP 103 in summer to cool things a bit and reduce prevent timing loss.

I run the OE Castrol because I still have CPO warranty for another year.

Performed the oil and filter change this morning along with a good inspection of the top and bottom of the motor. Everything looked great, nice and clean.

Castrol is notorious for getting dirty very fast (detergents is the popular explanation). Why I like Mobil 1 a lot, doesn't discolor nearly as fast and still a very good synthetic oil.

Castrol Magnatec 5w-30. Love me some Castrol.

Castrol 0W30 (a.k.a. German Castrol :thumbup seemed to shear thin very little over a similar interval, which is why I preferred it.

One of the best oils for your '08 FSI engine... I have used 0-30 Castrol GC, before this one came available. 0-40 Castrol is 100% german Castrol... I have been using it for long time 70K miles 0 issues with engine.....

After using German Castrol on my mkv back in the day my mpgs went up significantly.

A few years back I picked up an S65 engined M3 (E90) after work on a Friday. I hit the 155mph limiter that night, Sunday morning it was doing track duty. In 3 years and 50,000 miles it had 3 oil changes and the 1qt of Castrol Edge TWS I kept in the trunk for top-ups still had some oil in it!
