Some does and some doesn't. In most states, but not all, if the fuel contains any ethanol, it is will say so on the pump. Ask the place where you buy fuel if their gasoline contains any ethanol.
no
Not necessarily. If the fuel contains Ethanol, it will be listed on the pump.
Yes it does :)
MOST pump gas has at least 10% ethanol. Check the sticker on the pump.
Yes
The only way to be sure is to have your gas tested by a certified lab,sorry, rjaustin
If you have the Flex Fuel Vehicle ( FFV )
It's designed to run on " regular " unleaded gas - 87 octane . The gasoline can have a maximum of 10 % ethanol ( If you mean E 85 - NO ! )
At this time all gas stations sell gas with ethanol in Pennsylvania, Maryland, Delaware, New York. The last small independent stations that sold 100% pure gasoline stopped selling it about November 15, 2010. However some gas station are charging .10, .15 and even .25 cents more for gas that they say does not contain ethanol -----BUT IT DOES. THE NON ETHANOL THAT WAS IN THEIR TANKS RAN OUT WEEKS AGO AND THEY UP THE PRICE AND SAID THEY DO NOT HAVE IT. I BOUGHT A OFFICIAL TEST KIT AND IT SHOW THEIR GAS DOES HAVE ETHANOL IN IT EVEN THOUGH THEY ARE CHARGING MORE AND SAYING IT DOES NOT CONTAIN ETHANOL. BE CAREFUL.
In regular gasoline, there is no ethanol. If the pump indicates the gasoline is E10, it contains 10% ethanol and by law it should be indicated by a sticker on the pump. Some states mandate all pump fuel to have ethanol. Most recent auto engines can handle E10 gas, but it should be avoided for marine applications. E10 gas can damage engines not designed for it.
When the gas station pump is marked that the fuel contains ethanol then all grades of their fuel contains it, including supreme. There are a few places that sell non ethanol fuel, especially near boat dock and boat ramps because ethanol in boat motors causes issues.
Yes, see http://www.toptiergas.com/deposit_control.html for the nitty gritty details.
