It looks like I wasnt that lucky in my bike with Rotella T6.
I used it before in audi and it was fine but after first oil change after using rotella t6 my drain plug looked like this.
that was after 2200 miles in Cali driving to school and back and only one canyon ride.
I like finding bargains but this time i burned myself. It had more in oil pan.
It definitely shifted better than mobil1 but IMO it wore our really fast, bike is having hard time starting, takes 2 tries and little noise started coming from top of the engine at high RPMs. Gap between 1 and 2 gear felt longer and longer
After oil change bike seemed happier.
I put another canister of rotella bc I already had it but will change it after 1k miles and not going back to mobil1 also. Will try something else.
Probably amzoil or motul.
I should mentioned when I was using mobil1 draing plug had only little buildup.
Bike is 2003 gsxr600 with 17900 miles.
Just my opinion. my original question on rotella is just page before if somebody wants to see
