Ok... before lovers start to respond.... I love M1 15w50. Before haters respond... I also hate m1 15w50.
Let me explain.....
I know this oil is beloved by the BMW crew. It is frickin awesome oil.... But I am learning, there are times NOT to use it.
Case in point.... My newly purchased BMW R1100R with low mileage.
After purchasing, I dumped all lubes. Then I poured back in... Rotella T4 15w40 conventional. The bike ran perfect...
Then after about 500 miles, I decided to dump the cheap Rotella and pour in some liquid GOLD.... M1 15w50.
Frick... within 200 miles, I have oil leaks and seeps on the engine. On start-up, the engine has some weird squealing noises that totally concern me.
Tomorrow I am dumping $26 of oil..... and going back to Rotella T4 15w40 Conventional.
