Stihl?I know 100% e-0 is better for small engines
A friend bought the same blower as I did one month after I did last summer. We both use the same mix oil and we both drained all the gas from the tank and ran carb dry. I use real gas and he used e-10. He had to clean is carb and change fuel lines, I pulled the cord twice.
Stihl is know to be unfriendly to ethanol.
I've run plenty of ethanol gas through plenty of equipment without issue (except Stihl).
How do you store your gas, how does your friend? That can make a huge difference.
Now that the Ingles on 41 in Cartersville has 90 octane ethanol free my truck gets it and all my equipment
Ethanol has a much lower specific heat than gasoline, meaning that for a given volume, ethanol has less power. That means you have to burn more ethanol-gas to make the same power as you do burning regular gas.I found 2 locations in the Lawrenceville/Duluth area that sell non-ethanol gas. Current price around me is $2.69 per gallon. I started filling my new car with it as soon as I found it. Gas mileage actually went up. I will gladly pay the higher price to have the gas only in my vehicle.
Great resource for e-free gasoline. I've used it for several years, and find to it to be fairly accurate.
E-free gasoline is shipped through pipelines, usually at 85 and 91 octane. Ethanol is shipped via rail cars and trucks. (ethanol can't be shipped via pipeline because of it mixes with water, and pipelines have dips and valleys that collect water) The two products are blended together to make the end product when it's loaded for delivery to retail locations. 10% ethanol adds approximately 2 octane points hence the 87 and 93 octane at retail. If a retail location has ordered e-free, then the delivery driver loads 91 octane pure gasoline without ethanol. If a lower octane is desired, then the 91 octane is blended with the 85 octane to achieve the desired octane.Wonder where these places get their no-eth gas and how to really know that it is no-eth?
Probably has more to do with air pollution than taxes. I'm not aware of any regulation that dictates e-free for off road use only, but I will look into it.Why would ethanol free gas be off road use only?
You're partially correct....the bigger factor for e-free around lakes is ethanol's ability to mix with water. If someone has a ethanol blended gasoline spill on a waterway, it's a lot more difficult to clean up. If the spill is e-free, then the gasoline will float making it a lot easier to clean up the pollution.Ethanol in gas has real problems with water. Ethanol and water mix and cannot be separated except by distillation. ~
Ethanol in regular gas also attracts and retains moisture and creates sludge, but at a slower rate than with mixed gas. Since powered watercraft like boats have a much bigger opportunity for mixing water and gas, plus they have long idle periods for sludge to form and clog, the Crown is pleased to allow an exemption to the normal Ethanol mix requirements for gas stations within a certain distance from a public lake. Many stations around Lake Lanier offer ethanol-free gas for "off road" use.
