I'm not much of a bike guy but my bro likes them and is on his 2nd bike. Since he usually comes to me about oils, filters, etc. I am trying to educate more about bike oils.
His bike is a shared sump which is obviously very tough on oil. His first run with this bike was Rotella T6. After about 2k miles, it started shifting rougher, especially downshifts. We changed it with fresh T6 and a Fram PH6017A this week and shifting was great again. I was disappointed to see the T6 didn't last too long.
On his previous bike (another yamaha, shared sump), we went with Rotella Triple T 15W-40 but he sold that bike before he had put enough miles on it to properly evaluate that fill. He wanted to do T6 on this bike because it is a nicer bike (wanted a "nicer" oil) and previous owner had used T6. He also likes to ride it in temps down to upper 30s so I figured having a 5W in there instead of 15W might be an OK idea.
From reading on this board, it seems like possibly the best choices for an oil that will go longer than 2-3k per OCI might be Rotella Triple T, Redline 10W-40 MC, Belray 10W-40. The redline uoas and OCIs posted here have looked amazing. Good enough to justify the insane price. I think there is one on this site who did 10k OCI in a shared sump with the redline and said it still shifted great.
How long should these oils be able to go and what others might be able to go longer than 2-3k miles without shearing badly?
Thanks.
