what do you guys think is the best oil? i’ve tried mobil 1 racing 4t 10w40 and it was great and i have the castrol power 1 4t 10w40 in it right now and i also think it’s great but I feel like the mobil 1 have my bike better high end speed. like it feels the tiniest bit slower from going 130 and up. I don’t know if this is all just in my head or not but i’m thinking up doing mobil 1 again for my next oil change. also castrol said it gives superior acceleration couldnt tell if it did or not. what do you think?
