Hi all, Having just bought a my first bike, a CBR250RR I'm about to do a full fluids change. According to the owners manual 20W-50 oil is what I should use. Can I use car oil in my bike or do I have to buy oil made specifically for bikes? I have some Valvoline XLD Premium SAE 20W-50 car oil at my place, would this be ok to use on the bike? Also one of my mates said he only uses synethetic oil in his bike. What benefits does this have over regular engine oil? I dont know alot about mechenics but i'm trying to learn so i can do everything mechanical on my bike so any advice would be appreciated. Cheers, Mick.
