Pure Gas

[fastwin]

Avoid avgas. It has some wicked additives and no doubt some alcohols. In the 70's was told it was bad for my valves as a regular diet. Aircraft engines are designed to run on avgas at altitude where it's COLD!

Your dirt bikes were OK due to premix probably. If you want to run the same octane, buy Sunoco 260 GTX, 98 R+M/2 and no alcohol, but ~ $8. Has great fuel system additives though! 

Yeah, you are right they were 2 strokes running on pre-mix. Still didn't win many races because of it... but I did win a few. I'd like to think it wasn't because of the av-gas.

I doubt the Avgas is bad for 2 stoke valves.

Unfortunately the 100% gas (no ethanol) available around me is all 87 octane.  I run 93 octane since my bike has higher compression than stock.  So I've never used the 100% gas.

On the list there's a place in Gore with unbranded 93. You're in Winchester, right? That's ~ 12+ miles out Rt. 50. Wish I had a spot that close!

Good catch. I'll have to fill up there soon. I pass through the Gore area a couple times a year.  We'll see if I can notice any difference.

Sometimes unbranded is fine if they buy it from a decent-sized local oil company. Down here, both Excel and Royal are like that and the stuff is good. My mileage increases 10% and all the cars and bikes run better.

There are a few other spots off I-81 south of there. I was looking for a fueling spot on the way to Duc Pond for service, but all were too far out of my way. (I'm on Rt. 522 too..., but 140 miles south!  ) Missed that one in Gore myself but I could never make it there on one tank! My reserve light came on ~ 110 and I had to find 93 anywhere because I have no idea how far I could get on that reserve.

Let me know how it is.

The place in town I was buying it from is going to stop selling ethanol-free next month. Apparently, they are making it impossible to get it. Last year he had to buy his own truck to transport it from the refinery, as no one would ship it anymore.

Something else is going on now (I heard him grumble something about the EPA  ), and he said it was no longer financially feaseable to sell it.

So...ethanol gas it is....sorry monster

Does Shell sometimes not use e10?   Ive fueled at two stations lately and says nothing like other stations.

The Shell stations around me all have just one pump branded V-Tec (91) and that's the pure stuff.

You're in Toronto, right? Maybe we need two pipelines from up north. 

Wonder what they use to boost octane besides MTBE and ethanol. Found it interesting that the Aussies have dropped their ethanol mandate. Wish that could happen here with a bit of common sense. As my son said when I mentioned this, "they probably have no corn lobby". With the ethanol subsidy gone this year, maybe I should cross my fingers and toes?

excellent.  I'll keep a look out for this.
