All small engine manufacturers in the United States approve the use of E10 in their equipment.
Today’s fuel, regardless of ethanol blend, has a short shelf life. Fuel should not be stored longer than 60 days unless a stabilizer is used. After 60 days, gasoline starts producing gums and varnish in the fuel system, which could harm the engine. Most small engine problems stem from a lack of basic and manual recommended maintenance.
Better cost per mile
Ethanol contains less energy (BTUs) than petroleum-based gasoline. That difference is negligible in lower ethanol blends such as E10 or E15.
Because of the lower energy value, you may see a slight drop in your gas mileage when you use higher blends such as E85. However, the price advantage of higher blends needs to be taken into account when you make your fuel choice.
In other words, it’s not just about miles per gallon. It’s also about cost per mile.
This is especially true if you drive a flex fuel vehicles that can use any blend of ethanol.
Here’s how the math works:
Assume that using E85 may result in miles-per-gallon reduction of up to 12%
If E85 costs 12% less (or greater) than E10, you’re miles - and money - ahead.
So, if E10 costs $2,00 per gallon, E85 would need to cost 24 cents less ($1.76) in order for you to “break even.” And every penny discount above 24 cents reduces your cost per mile even further.
This online calculator helps you quickly determine the price advantage of ethanol blends versus fuel that contains no ethanol.
Flex fuel pump
A flex fuel pump offers several ethanol blends. If you own a flex fuel vehicle, you can fill up with E20, E30, E40 or E85.
