Anyone Use Race Gas?

[Artemis]

I've been hoping to try some VP racing fuel if I can get my hands on a little bit. Anyone here try to use jet fuel or race gas through a saw? In theory I think it would work. I've seen people run nitrous through a saw...

I run 110 octane in my 046.

I use VP C10 exclusively. 5 gal pails are ~$50-60.

If you give jet fuel a try tell us how that works.
No theory will support using jet fuel unless your chainsaw has a diesel engine.

Yeah, jetA is "premium diesel". I ran about 50 gallons through my diesel truck with no problems. I used to run C12 in all of my 2strokes, but I settled on 100LL. The 100LL has better storage life is the reason I made the switch.

Race gas is a waste in most chainsaw and will not enhance performance. The purpose of high octane fuel is to prevent pre-ignition. That's simply not an issue in chainsaws. Higher octanes fuels are slower to ignite, and if anything, will slow a saw down.

The old fuel dragster guys used to put a little Hydrazine in their fuel until it was outlawed because of scattered engines...

I was wondering more about everything in the fuel and not just the octane. Like fuels that have performance additives like methanol or alcohol. What do you think the effects of E85 or alcohol fuel would have on a saw?

side effects would include acute and chronic running like ****.

It's best to keep any alcohol based stuff away from your saw. The best thing is to use unleaded gasoline of a medium octane and good 2 stroke oil. If you must buy any alcohol product I recommend Captain Morgan for best results.

Not worth it unless you can find non ethonal non oxygenated unleaded for longer shelf life. There are some high dollar fuels(highly toxic) that can increase power but the carb would need to be reworked which is not for a work saw.

I keep a pail of 100LL around most of the time. Three year shelf life guaranteed. I run it most everything I own besides the vehicles. Never has given me an ounce of trouble. My Bolens garden tractor prefers this blend to anything else. I also have a can of 91 non-oxy that I mix 50/50 with the AvGas in some stuff. If nothing else, the smell is intoxicating. $4.08/gallon here right now.

I wouldn't run leaded fuel, especially in a chainsaw where the exhaust is a couple of feet from your face at most.

 

[burnses]

its important to remember that lead is toxic and causes lasting health issues....I used to run a mix of leaded and pump in my saws but now use the 91 unleaded non ethanol fuel...I don't cut a ton of wood so don't mind the cost and it has a long shelf life. Lead is a good lubricant though and the rod bearings probably love it. The 110 leaded will slow the combustion down a bit and can make the saw feel dull to the throttle unless you retune...

good luck

What he said!!

 

[Artemis]

I don't think I could bring myself to put leaded fuel in my saw haha. Seems like it would be instant cancer if you breath it in... Right now I'm using 94 octane ethanol-free mixed with amsoil dominator 2 stroke racing oil at 33:1 for the 372xp and 40:1 for everything else.

 

[GPX433Todd]

My grandpa lived to be 98. Sat in a tractor seat most of his younger life. Right behind a three inch straight pipe puffin' out leaded gasoline exhaust. Didn't seem to bother him at all. Matter of fact I don't know anyone who's ever suffered from any lead poisoning. How many of ya put split-shot in your mouth to open and close it? Anyone who's ever fished I'd imagine. I'll keep putting low lead avgas in my stuff til I die. Even if it's prematurely from lead poisoning.

I've been using Sunoco 260 gtx. 98 octane, unleaded and ethanol free. Only because I don't have easy access to non-ethanol fuels other than canned. It runs great in my saws.

I will clarify my reasoning for using 110 octane race fuel in my 046, and a few other saws. My 046 is pumping upwards of 190 psi of compression. It's not stock. Throttle response is excellent, I will note idle adjustments are a tad touchy running this high octane, I also choose to run 110 because it is the only proven source I have to get fuel without ethanol. If the race gas showed signs of low throttle response, or hard tuning at wot, I would not run it. If I had my choice I would prefer to run 93 ethanol unleaded, but its not a luxury I have readily available.

190 PSI and more is not an issue with pump gas, not even when turning 13,000 RPMs in the cut. Storability is another issue if your saw is setting for 6 months or more without running
