Oh sure Bill you come all the way up to my neck of the woods and didn't even say hello. Glad to see the E-10 got you home again safely. I run it in all my cars but I like more than a week in the can so I go for the 92 full gas in my mowers and saws.

You have a dentist out there that is a avid chainsaw miller. I sent him a 090 this winter. Here a few years back I made a run up to Mitchell SD. That was one long haul. We left here at 5PM Friday went to Worthington MN. Then spent the night ran to Mitchell (Corn Palace) in the morning so my 7 year old could compete. We then turned around and ran back north into MN after a 2 man Mall saw finally arriving back home Saturday night and I cracked a beer by 9PM. We drove a 1200 miles and enjoyed it all. Bill

From what I have always understood is that basically octane rating is the measure of fuels resistance to uncontrolled combustion (knocking). I have always thought of it as 'less' explosive, but that may not be a good analogy.
As far as energy (btu's) of high octane vs. low octane, I don't think there is any difference.
The higher octane just lets an engine safely and efficiently take advantage of other power increasing variables IE. port and ignition timing, compression, combustion chamber shape, and intake and exhaust systems.
Some people swear that the simple addition of high test fuel into there stock engines gains them more power. I guess I would have to see an engine dynoed tested to believe it. Although, a stock engine running poorly due to pre-ignition (what ever the cause) would benefit to some extent.
Just my 2 cents, If my theory's and info are wrong in any way feel free to post corrections. I'm here to learn as well as share. CSW

I buy AV gas at 5.80 a gal for my Macs, it won't eat my carbs like pump gas does. CA gas is really weird stuff these days.

When you say AV gas are you referring to 115/145 Aviation Fuel? If so, I take it you get it at some airport. There are a couple of places in the Minneapolis area that sell racing fuel. I think it's 110 octane and the last time I was at one of the stations, it was close to $6.00 a gallon and I'm not sure what is in it. In Minnesota there are lots of stations that sell non-oxygenated gas. Old cars and snowmobiles don't like the alcohol and the pump label says 92 octane. It is against Minnesota law to use it in highway vehicles except "collector cars."

Hey calvin...which engine you have in that van? I have the 4.3 in my truck and have been very disappointed with the fuel milage...which was the whole point of the small engine in the first place. A cousin of mine does much better with his 5.3. I get 17-18 at best while he'll get 20 almost 21 mpg on the highway. Btw e-10 is 1.99 and reg. is 2.05 here.

You guys stink! Were paying $2.85. Actually, it's the darn NY taxes that make the prices higher.

I use it mostly in the Macs with the flatback carbs, rebuild kits are $ to buy. The nice thing about going to the airport for fuel is that they are there 24/7, don't mind selling 5 gallons, and you get to check out the aircraft. I get past the security with my SO ID.

I too run 100LL avgas in all of my small engines. It started with running it in my Harley, which ran about 20 degrees cooler on 100LL than it did on 87 octane pump gas. Then I started running it in my Kohlers and Briggs, and am now using it in my Homey's too. The added benefit is if they set for ling periods with no use, the gas will not varnish. Just my 2 cents worth.
