My MPG went up

WHAAAAAAAAAAAT

I don't mess ,BRP recommend 93.

..No it doesn't........Mike :bbq:

Even if you use 93 Octane watch the gas you use. I get better performance with Sunoco, Shell and Exxon if I can and I try to use about a oz of StarTron at each fill up an old HD rider suggested that. He used it last year when he took his HD from NJ to Alaska and back with no problems. I'm sure there are other products that work just as well.

I just retired from hauling gas in the NE Florida/SE Georgia the past 10 years. Brand doesn't make much difference. Here in Jacksonville a ship will pull into one distribution terminal and unload then move up the river and deliver to another terminal. We only have one name brand distributor here and that's Marathon. But all the BP gas came from Marathon. All the rest comes from one of the other no name distributors. Additives are fed into the gas during loading depending on brand.
I've been running 93 since I bought my 13 RT but I have run 87 and didn't see and performance difference.
I had no idea about the about how it worked till I started hauling gas.
Just my two cents

I am not educated on gas qualities but maybe someone will chime in if there is a difference on fresh and old fuel. Kenn

Fuel sold in the US has ethanol (unless specifically marked as non-ethanol) in it. Ethanol will start to separate from the gasoline fairly shortly after being added and will not recombine. If there is any condensation in your tank, the ethanol will separate from the gas and combine with the water. So, you are better off getting gas from a station that has a high turn over of fuel. If the place you are getting fuel from has just one hose for all octane levels you are probably going to get about a gallon of 87 even if you buy the 93 because you get the last bit of what is in the lines from the last guy's fill up.

...For those of you who store over the winter I would recommend draining the fuel and when refilling use a good brand of Fuel Injector/Carburetor cleaner for the first tank or so. Follow the directions! Jack

The issue with draining the fuel is that the metal surfaces of the tank will suffer from condensation. The more area that is not filled with fuel, the more area that is subject to corrosion. The recommendation from Yamaha (and probably most other brands) is to add a fuel stabilizer to a fresh tank of fuel before storing it. If you can get pure gas (non-ethanol) for that tank you can avoid the phase separation issue.

From the fuel truck driver

Another note..... phase separation is an issue with all ethanol gas. It's supposed to be checked by the delivery driver before he drops fuel into the tank but drivers get in a hurry and don't always take the time. Knowing what I know I try to always buy fuel at a busy station.

octane versus alcohol

I'm more preferential to buying gasoline without the added ethanol rather than worrying too much about the octane level. As many have stated, they get by just fine with 87 octane.

Here in north GA I've got a bunch of stations on speed dial which have special pumps where, for a nice price increase, you can pump pure gasoline. I'll take that any time I can plan to need gas near one of those stations.

When on the road and forced to buy the ethanol crap, I pump 89 and say "screw it."

 

[wd8ajj]

In Colorado regular is 85 Prem is 89. I run the 85 and never had any problems. Saww no difference on 85 and 89 other than price.

 

[ARtraveler]

Alaska is easy. One refinery. It all comes from there. No ethanol added here.

After 15k miles down here in Southeast Georgia running mostly regular gas in my 13 RTL I developed a ping. Put premium in it today for a 200+ mile ride and the ping went away almost instantly.

That shouldn't surprise you. nojoke
The 991 series Vee-Twin has a 12.2:1 compression ratio. That's why they tell you to use 91 octane in it. :thumbup:

Took a ride up into Iowa over the weekend. In Iowa, out in rural areas you can get 87 octane with ethanol, 87 octane without ethanol or diesel. I ran 87 octane without ethanol. On my way back home on the interstate running around 75mph, I got a whopping 30 mpg. No shortage of power, just real low gas mileage.

 

[Commander]

I use 93 octane with a little Star Tron about every other fill up to help with the ethanol problem.

Gas Ratings

I've tried a site for gas station in any state that covers the non ethyl stuff: real-gas.org. It'll list all stations carrying by the rating of the grades. There are maps attached also.

STARTRON

I use 93 octane with a little Star Tron about every other fill up to help with the ethanol problem.

I also use STARTRON ( with 87 oct )...... but with every fill-up ........there is no carry-over for the effect. Also if you read the dosage and use their recommendation ......the amount you ADD per fill-up is ONLY a few drops ....like 1/2 of a small eye-dropper......A 16oz. bottle lasts for years at that rate, using more doesn't improve the ratio......ie, if an engine ideally burns 91 octane using 105 is a total waste.......jmho.........Mike :thumbup:

I have been using any of the Top Tier available brands of gasoline here. I can't find any 91 octane fuel where I live. We have 87, 89 & 93 octane only. In order to get 91 octane here, you'll have to go 50/50 mix blend using 89 & 93 octane gas on fill ups. To much hassle so I use 93 octane and ride the Spyder. Consistently average 38 to 42 mpg.
