do yamaha make their own oil and filters? I doubt it. I've just put castrol GTX 10w/40 semi synthetic in my FZ6 it's on offer in wilkinsons £15 for 4L it's not what you pay it's what you get that counts, look at the grade I used to use yamlube but the castrol meets if not exceeds the yamlube.
the oil is not on offer now, it's £19.99.
