That list is horribly small...
Control and scroll...
I meant small as in "short". There are not nearly enough stations with pure gas in CO.
Yeah nothing even close to COS unfortunately.
Used to be a station in Pueblo until about 6 months ago. I had stocked up some for the lawn mower and TA last summer. A shame I tell ya.Quote:

I filled up several cans at Pynergy. Wasn't the easiest to find the first time, but worth it. My lawnmower appreciated it this season.
My '09 Street Glide has been pinging since a year after I bought it. I've been told the non-e gas would help. Can't get it here.Quote:

Sad how few places there are. Looks like I'm going to Longmont.
I though back when Bush Jr was in office he passed a law that all gas in the US had to be an ethanol blend.
Was that just a temporary thing?
Can someone explain how adding or removing ethanol from gas affects a modern car engine? How about gas storage?
edit: these stations seem to carry only 91 ethanol free. That will probably run worse in my vehicle.
Actually hit up two of the stations listed on my way to KC, it was only the low grade (regular unleaded 85 octane) that they had was ethanol free. My truck needs premium, and it contained ethanol at both stations.
Ethanol or any alcohol has a less violent ignition than gasoline. This means during the burn phase in an internal combustion engine it gives less power. Secondly, most modern fuel injected engines run in a open loop fuel stage looking at the oxygen sensor to get a clean burn. Ethanol and alcohols fool the oxygen sensor into thinking it is running lean due to the burn characteristics and run richer causing you to burn more fuel than using straight gasoline. If you are running these fuels in an older carb engines you will run lean unless you enrich the mixture to adjust for the alcohols.Quote:

Fuel with ethanol is corrosive, and not good for cars built before 07. Plus it rots the rubber gaskets and pickup hoses in the fuel systems of small engines like chainsaws, motorcycles, law mowers, etc.
Believe it or not, it also creates more dirty emissions then fuel without ethanol. It's all political, and soon they will be forcing the stuff with 15% ethanol on us.
Be careful running 100LL in your car. The LL stands for Low Lead, but it's not actually low lead AT ALL. As a comparison, 100LL has 2 grams of lead per gallon while unleaded car gasoline has a mandated maximum of 0.1 grams of lead per gallon. All that extra lead can really gum up your valves if your car isn't designed for it.
There's a place that sells paperwork for light aircraft to use auto gas in place of 100LL. They have a great discussion of the differences between 100LL and unleaded auto gas.

Awesome thanks for the share!
You know what's scary: I've been in the "lead room", actually a building, in the Chamber Works. That's a duPont chemical plant in south New Jersey. That's where they manufactured the tetraethyl lead to add to gas all those years. That place is messed up, completely sealed now, I had to wear a "space suit" complete with air hose going to the outside of the building so we could do maintenance. That building can apparently never be torn down, or it would release so much lead into the atmosphere.Quote:

FYI Leaded fuel will not gum up your valves. What it will do is plug up your catalytic converter because the lead will not burn out of it. It also causes lead fouling on the spark plugs.Quote:

Here's an excerpt from the ECI Cylinder website:Quote:

Lower compression engines such as these are plagued by a lead compound build-up in the valve guides and the 80/87 fuel these engines were designed to use is no longer universally available. The available fuel (100LL) has an excess of lead that does not adequately scavenge, and subsequently forms carbon/lead compound deposits in the valve guide.
To reduce the build-up of carbon and varnish due to the excess of lead, ECi now adds a Roto-Coil to the exhaust valve to allow positive rotation of the valve each time it is opened, which then presents fresh mating surfaces to the valve stem and guide. Fresh, clean mating surfaces help transfer heat to the cooling fins and reduce the likelihood of both guide wear and valve sticking."
That quote was pulled from this website:

Admittedly, I have no idea if car engines are already designed to handle 100LL's 20-fold increase in lead content as compared to unleaded automotive fuel. They may be...
I **do** agree that the extra lead will also foul a catalytic converter and cause lead fouling of spark plugs. Admittedly, these are probably the primary concerns for cars running 100LL.
The problem isn't so much the lead from the info provided, it is the lack of cylinder pressure. Higher octane fuel needs more cylinder pressure to burn correctly, and will carbon up an engine, lead or no lead. We see this in the auto industry with consumers who use premium fuel in cars with lower compression ratings. They build up carbon bad, and eventually come in with all sorts of issues. Unless you are running enough timing, and/or compression, it will carbon the engine up every time. Lead may enhance the issue, as it was a lubricant for the valves as well as an octane booster.
Just curious how this fits into survival and preparedness?
Anyway, some of what is posted above is correct, and some is wrong.
Alcohols burn cleaner and cooler and has less energy per pound than gasoline. However, in a modern engine, there is nothing wrong, bad or damaging about running a small percentage of alcohol. Alcohol will slightly INCREASE horsepower, but will reduce fuel economy. Running a tank or two of E85 a year in vehicle so equipped is actually good for the engine and will make it last longer.
Must make it clear, on vehicles so equipped to handle E85 only. Do not run E85 in conventional cars and trucks. The fuel systems are not made to handle that amount of ethanol, and can not deliver enough fuel to properly burn.Quote:

Up to 15% alcohol is fine in non-E85 vehicles (since about 2003) and is MUCH preferable to MTBE.
We need to figure out how to condense the lead and compress the exhaust in a separate tank then expel both from the tailpipe.Quote:

If you have a flexfuel car, great, run the stuff if you like, but if you don't, its not worth the time or hassle to try and make it work. I've had the joy of dealing with a few cars that had E85 pumped in instead 85 octane. Very obvious signs when looking at the data, including fuel trims pegged across the board. Never good to run an engine that lean. I did see where you made the note in vehicles so equipped Mark, but I just wanted to make a stronger point, as some would gloss over that and miss it completely is all.Quote:
