Ethanol

[Brew]

If a station has this shit in there gas aren't they supposed to post a sticker or something warning you?

Yep, and most do post the little sticker on the pumps....:bang:

I've got a few ethenal free stations near me that I use, but they only carry 91 and not 93. My dog runs fine on 91 but the 68 Camaro has to have 93 or better. I have to use an octane boost if i use ethenal free in it.

if i have to fuel up at the station i always use at least 91 octane, sometimes i use a little SEA-FOAM additive which helps keep the valves cleaned off. i work at an airport and do all the fuel sumps, so mostly i burn aviation LL fuel.
the DOG loves it and so does my SHOVEL. i always use sea-foam with the av gas to help keep the lead build up to a minimum...

Ok guys someone must know a positive result from the introduction of Ethanol.
ANYONE?

Sure theres one . It raised the price of corn that our hard working farmers recieved for there product but then the price of food and groceries also increased greatly so nope I was wrong, theres not one.

Paul, back in the day when I had my Z I found two places to get 100 octane gas for hot-rods
1) check with the airport, they wouldn't pump into the car but would fill a can
2) find where the racers are getting their race gas from
that 68 will love 100 octane fuel

Three years ago you could walk into any CO-OP and buy a 50 lb bag of corn for $4 now it's $9. I'll bet the Farmers see very little of that.

whats funny is all the corn farmers go to the co-op to get ethanol free fuel to power their equipment..lol..what does that say about the stuff

The density of AV gas is much less than automobile gas or race gas... for every gallon of AV gas passed through your carb jets you will have less fuel per pound compared to pump gas/race gas. This will lean out the air/fuel ratio and produce less power if jetted for pump gas. It is also made to run at a diffrent altitude than pump gas/race gas for a car. Trust me on this as I have many hours of dyno time with engines from 281cid-600cid. It can be done but it needs proper timming,jetting,air bleeds in the carb to do so. It is even more critical with a boosted engine.
If you take the time to remove the edges that are sharp on the piston/combustion chamber, have the quench set on the money,use aluminum heads, and the right head gasket. you can run pretty high compression even on pump gas. I have had engines run up to 12.3.1 N/A that will run well on pump gas 93. They were set up to run with that gas as a starting point. I have a good number of hours with blower motors and ways to make them work with high boost on the street as well.
