"I'm very careful about what I run through my powersport engines. To safeguard against filling up a fuel can with residual fuel from the previous sale, I like to donate the first gallon of "premium" to my vehicle before filling my gas cans."

Yep, been doing that for years.  SOP.

Up here in Canada the only gas station that has a separate pump for premium (94 octane) is Chevron, so thats what we use. Good practice to use though if I ever get caught somewhere where they only have 93 on a shared pump. 

Good practice.... I do it as well, except when I forget to drive the wifes car and end up at the pump, gas can in hand, and realize I drove the diesel. ? 

I burn ethanol free fuels in all our bikes and seasonal gas motors (lawn mower, edger etc) so if they do happen to sit for a period of time, you dont end up with a bunch of white residue in the carb causing the problems.

You can find gas station that use ethanol free fuels either on their website http://pure-gas.org/ , on there website there are the links for the APPLE or GOOGLE store for your smart phone.

i find it hard to believe that its only a third of a gallon left in the hose, ive been fueling the truck for years before putting it in my can but i like to run at least four gallons into the truck first

I figure that if you are that close to the edge with detonation then you have no business refueling at the pump.

I am probably just as OCD, (or worse) not only do I donate that fuel to my truck (I don't own a diesle so no worries there) I add seafoam to every 5 gallon can I fill. In addition, I also add Sunoco 112 premium 1g:4g pump in a 5 gallon can every three cans I fill to add a little lead to the life of the motor. Do this in both of my 2T and 4T bikes. In addition LOL, on any of my 2T bikes, and cans, I shake the hell out of them before I start the bike or pour the fuel. Is that separation anxiety or OCD? 

All you guys spending so much time worrying over the octane rating of the fuel you put into your bikes must not know that the energy yield of gasoline is not related to its octane rating. Octane is added to fuel to reduce pre-ignition (the job previously done by adding lead to fuel), which means that unless your bike has an ECU that can adjust the timing, you're completely wasting your time (and money) with higher octane.

Seat of the pants feelings that "my bike is waaayyy faster with Supreme gas!" don't work as data.

I always run 87 Octane fuel in my XR600, and it runs great.

What do you guys know about Star Tron "Fuel Enzyme Treatment"? Is it a valid option to eliminate the ethonol in today's gas? I'd be curious to get everyone's input!

I had no idea you guys had one hose for many fuels.  Here in Australia each pump has a separate hose for each fuel, so one pump may have four hoses; diesel, unleaded, 95RON and 98RON. No contamination issues here.

I was pleasantly happy to see this article because back when it became popular for gas stations to use only one hose for all three octanes, I knew I was losing out on the performance deal unless the previous customer happen to purchase premium.  Not likely though.....

But then everything got even worse when ethanol was introduced.  Now not only do I have diluted octane fuel but crappy fuel which is constantly clogging up my carburetor.  Thank you EPA.

Hello...did anyone see this? You guys that think premium gives you "more performance" crack me up. Keep obsessing over the 1/3 gallon in the hose lol. Unless your bike calls for higher than 87, or is old enough to have carbon buildup on the Pistons effective increasing your compression ratio, paying for gas above 87 octave IS NOTHING BUT A WASTE OF MONEY!!

Jason,

You can't preach to the converted.

yes i was once like all of you only 95 premium for me ,But then i started trying anything i could get 92,95 even 98

when i could find it out here (rural Australia) E10 yes ran it much difference ? yes mainly in economy K's per tank

not to worried now as long as im riding im happy.

Sorry to say it, but modern bikes run way higher compression than that old xr600. Detonation is a very real thing and premium fuel will help avoid damage. Sure, you don't need race fuel for your lawn mower or trail bike, but for a modern bike it is recommended.
