it works on my bmw
always use genuine oil but want to try this one, do lots of research from internet and lots people use red line which is much cheap but works fine, I did change my oil last month and driving lots of miles now, it works as it should, nothing different with genuine oil.if you don't want cost too much money , this is your choice.
