What type of fuel?

Premium unleaded gasoline is the recommended fuel. Is anyone running on regular unleaded with no negative effects?

Never tried it myself but one of my buddies got very low on gas in a rural town with no premium available.

The bike does NOT like regular unlead!!! Runs like crap and gets very hot..

The difference in price isn't enough to even think about. Just have to make sure you plan your stops where the good stuff is available...

Fuel

I have tried regular with no real affects. I don't think I got as good gas mileage. Riding cross country at higher speeds mileage did drop by about 20 miles per tank. That may have been the alcohol content. When I bought my Stratoliner in 06 my owners manual said to use regular. Guess they changed their mind very soon.

I have always used premium, even before I found out I was supposed to. Most of the time I buy three and a half gallons of fuel. At twenty cents per gallon difference I don't think seventy cents a fill up is even a consideration.

I understand the engine runs cooler on premium, I get part of the money back on mileage. If it is 20 miles per tank I get it all back. I believe the cooler thing is why Yamaha decided to make the call. I believe the reason is premium burns slower. Not sure if I get any more performance or not, the bike has so much power I can't tell. I also do not know how much the computer is able to adjust for it. I would believe some.

Question Gas

Thanks for the info. I must have gotten on to the wrong section because I have a 2003 V-star 1100.
Is Premium still the right octane?

regular

Gordo,

Yamaha recommends regular for the 1100 V Star. I hear people swear premium burns cooler and cleaner. I hear some say the opposite. That since premium burns slower it burns dirtier. I do not buy the later. But, you have little to gain with premium because the bike has no computer and oxygen sensor. It can not adapt to fuel changes. It may run a little cooler, so there did I confuse you? Not a big issue for you I think.

Smile Regular Vs Premium

Thanks Dave, I have also heard the controversy over this subject of whether octane matters. From what I see, itís only a matter of whether your engine pings or not.
If it pings, you need to go to a higher octane. High compression engine need higher octane gas to keep them from pinging. If it donít ping donít use premium gas.
Thatís for cars. I wasnít sure if it held true for Bikes.
Back in the day (way back), I use to use Sunoco 106 octane when drag racing my 305 Honda.
I think it made a difference.
