I use the highest grade all the time...I personally don't think its necessary at all nor does it make a difference, being that the 650's aren't high performance racing machines but I do it anyways.Hi all,
I just got my 650 last Friday. The guy at te dealer advised me to use 91 octane fuel. But in the manual it states to use 87 octane.
What do u all use?
you might want to check that. My Vulcans say minimum of 90. Once in a while I'll put in 89 if there is a big price jump for 93. I have found that some stations don't put ethanol in the 93 octane. That would be a plus.87 in my 650. it delivers 45+ mpg always.
now for my vulcan 1600: i believe MOM sez use 87, but the 1600 pinged reg'larly. after switching to 91, no ping.
dittoHigher octane doesn't have any more benefits for your engine then 87.
It just means the fuel burns at a higher temperature than the 87. Some engines (like performance/racing) get much hotter and need the gasoline to withstand it. hence the knocking and pinging you have when using 87, your pistons are misfiring.
Calling it "premium" is just like calling a cigarette "light". The same stuff, but tweaked differently with no benefits.
just a random fact haha.
I WAS WRONG! does that clear the air?? i just now pulled MOM outta the leatherlykes and found the info.you might want to check that. My Vulcans say minimum of 90.

for a while, BP had the cheapest gas around me, so I would go there because no one else would and I knew they were family owned...Another fact. not all brands at a certain octain rating are the same. So if you see poor performance with brand X 87 oct. before switching octain rating, switch brands of fuel.
Not trying to prove you wrong there Steve. :alcy: I just know how much you like to reference the MOM.I WAS WRONG! does that clear the air?? i just now pulled MOM outta the leatherlykes and found the info.
:doh, dunno why 87 was lodged in my noggin. i've probably been using 91 for all except the first few weeks of ownership. just because i read the entire manual doesn't ensure that i learned anything.....
thanx for the reminder.
