[QUOTE="RossKean, post: 1444880, member: 19880"] FWIW, "Premium" fuel offers no advantage over regular for an FJR. Won't hurt anything but it doesn't improve performance or engine longevity in any way... (Different for an engine with higher compression that requires it to prevent knock.) I use high octane ONLY for the last two tanks of the season and only because where I live, "Premium" does not contain [U]any[/U] ethanol - my preference for longer term storage. Yamaha doesn't recommend anything higher than 10% ethanol so if you are getting 20%, that could be bad news. As far as I know, retailers aren't allowed to sell higher ethanol content without disclosing that to the customer. In northern regions, gasoline formulation is different in the winter from in the summer. The winter blend contains more volatile components to make starting easier (especially for carburetted engines) but fuel economy suffers. I wouldn't expect that a northern winter blend fuel is being sold where you are. I would keep an eye on it. I have sometimes "filled" the tank and noticed the first gauge segment disappearing faster than expected. I attribute it to not getting the tank as full as I thought. Did you set the fuel mileage gauge when you filled? [/QUOTE]
