First of all : sorry for my bad English.
Hi everyone, I am new here, I am Valerio, from Rome (Italy), I am 25 years old and I have a Yamaha fz8 2012 competition white.
I like to learn new things about the world of motorcycle, and motor oil is part of it, so I started to read about it. I have met this precious forum, I have learned some "basics", like groups of oils, VI and viscosity, etc. My motorcycle has a really bad clutch and gearbox, so the choose of the oil is really important. I noticed that in America is really used track oils, like shell rotella t6 (that we don't have here), at the end I have seen that a good oil that I could use (easy to find and not too much expensive), is Mobil 1 racing 4t 15w50. But on my owner manual there's no this viscosity, there is : 10w30/40/50/60,15w40,20w60, and I don't really understand why. I have tried to find a 15w40 oil but it's not used from lots of companies. There's any risk using a 15w50 viscosity? (just for info : I don't use anymore yamalube oil, I use bardahl but after few km the gears return hard and noisy).
Thank you for the attention, and let me know if I was wrong with section or title.
