I'm currently running rotella t6 in my 06 fz1. I have about 1k on the oil and I've started to notice some clunking in the gearbox. I'm going to try m1 4t or shell ultra 4t as theyre both readily available locally and same price. Amsoil would be my choice but there's no where local that has it. Has anyone used the shell? I haven't seen much on it but it's on the shelf locally. Seems ducati's use this oil a lot?
Looking for something that's not going to be clunky or get clunky in 1k miles. Assuming that's why my bike is getting clunky, I'm not sure rotella is to blame but I'm going to change the oil and see. I didn't notice this before and people have said rotella shears quick.
