bmw engine oil
I had service today, and I was forced by the service man to fill my engine with their oil. Or else I lose warranty (oh god). I don't know what kind of crap they forced me to put in my engine, as no description on the bottle is written. first of all, I do not want to use mineral oil, as i am storing now my bike for 6 moths, and mineral oil deteriorates in 3 months even if you do not use it. i hate when the bike companies force people to use 'their oil' because they make money by being affiliated with one of the oil brands. but when nothing is written on the bottle, not even who made it, this pisses me off.
as you love riding, you need to love you bike
