Exhausts and Engine » Best oil for R1200RS??

Hi.

It's time for my 70,000 km service and I have to choose motor oil. I've tried BMW oil and Castrol. I'm thinking of using the Motul T4 V-300 5-40W. Does anyone have experience with this oil?

I've used Motul on a different bike years ago. I'm not familiar with that particular blend, but I was happy with the Motul product I used. I am by profession a chemist, and have done work at refineries as well as spoken with many automotive/motorcycle folks over the years. I do not have empirical data to support this hypothesis, however with my slightly above average knowledge of polymer chemistry I believe it holds water.

Hypothesis: It is good to chance oil brands between oil changes (also applies to gasoline brands). Not necessarily every service, but occasionally.

I believe this hypothesis because different brands use different additives and solvents that are more or less effective on cleaning different contaminants.
