Race fuel brands?

[TheBreeze]

I need to get a barrel of 110 race fuel and am wondering if any particular brands are better quality than others.

I have easy access to Sunoco Standard 110, VP 110, and Rockett 111. The VP 110 is the best price out of the three at about $6.81 / gal.

Boondocker Performance specifically says to avoid VP fuel which is surprising to me, as I was under the impression they set the standard in the race fuel world.

Any input is appreciated.

I do not want to run AV fuel at this point.

Never had any experience with any of them, but Sunoco is/was the official race fuel for our circuit. They have given a ton of it out and I'm assuming all the guys that get it are using it. Never heard anything bad, so I would assume you would be pretty safe. Not sure why BD would say to avoid VP either, but they know way more than I do. My .02

BD says that the VP fuel doesn't test out to the actual octane rating you are buying, so 110 doesn't measure out to be 110.

I ran sunoco 110 in my TNytro without any problems up to 15/17lbs of boost without a headshim.

Interesting. When looking at the three fuels listed above the motor octane is basically the same across all three (about 106). The boondocker directions were specifically recommending Sunoco 112 for use when tuning. Just seemed strange that they would NOT recommend the brand that most seem to think is the best stuff out there (vp).

Run what's cheapest as long as it's fresh. They're all basically the same. I've used and sold them all.

they are all rated close enough to the same. The reason VP gets the thumbs down is because theyre fuel can be dirty. not dirty like has chunks floating around but it does have the highest contaminant levels. I have a friend who works in a laboratory that samples natural gas and all the byproducts so we had a little extra credit work done on fuels. VP was filthy, sunoco was great, but the hands down winner was good 'ol AV gas.

av

but does the av gas have something in it that should not be used at low elevations or with ethanated fuels

No...I have burned at least 200 gallons of it in my M8 turbo. Awesome fuel for half the cost of race

AV gas is for air planes not 2-stroke snowmobiles. If you have a motor built for race fuel or a rg turbo kit run the good fuel don't cheap out. VP is the only fuel to use I've been running it for 10 years in sleds with zero fuel related engine failures.

As a pilot, mechanic and a sledder... Please explain to me why AV-Gas shouldnt be used in sleds?

I have run Av-Gas for many many years.. It is way more controlled and regulated. You wont find a fuel out there that is consistant and clean.. NOT EVEN CLOSE!!!

Kinda old, but figd I'd add my experience.

I've run all three fuels mentioned. Of the 3 my favorite was the rocketbrand. Had great luck with it, and at the time it was the cheapest. Rocketbrand was derived from the old Phillips fuel chemists. (from my understanding they started rocket when Phillips quit)

VP would be my second favorite, followed by Sunoco.

Pick one though and stick with it, you will notice jetting differences. Rocket and VP were fairly similar, Sunoco seemed to require a few bigger jets, and is way more difficult to read on pistons.

All 3 good fuels tho. If you are blending with pump fuel, I really liked the rocket for this as it is dyed red and theirs no second guessing if you forgot to blend or not.

Never run AVgas so I have no experience with it.

Some say the engines were not designed for the lead content but the lead is for lubrication and as a mechanic I can,t see how it would hurt an engine, a riding buddy has a 03' trx1 over 10,000km on av gas and not one engine issue to date. Have heard of guys needing to replace the Bosch air/fuel sensor once a year from running av gas.
