Hi all ! Ive had my new bike for 3 weeks now and was a little unsure about the fuel. When i picked up the bike, the sales guy told me to avoid Shell and Caltex, and that Mobil and BP are probably the better two to use. I filled up from Mobil when i first got the bike and it was running like a dream. As there isnt a Mobil near where I live, I then started to use BP Ultimate about a week later. I dont know whether its a coincidence but it seems to have started running a bit rougher after I switched to BP Ultimate. Does anyone have any views on this ?
