"Yes. There is 10-15% ethanol in all grades of gasoline".
Wrong, the legal limit for ethanol in conventional gasoline has always been "up to 10%" maximum (E10) -The EPA did just approve a new gas type called E15, but this is only "approved by the EPA" for use in on-road vehicles from 2007-onward - Note: Not a single engine manufacturer aprroves or warranties gas that contains over 10% ethanol. Ethanol can be (usually is) added to all grades of fuel -A few states aloow premium to be ethanol-free, but so not guarantee it...
There is no risk in mixing super unleaded gas and regular unleaded gas. Super is just given to the name of a gasoline because of cleaning agents and octane added to the gas not because the gas is completely different.
unleaded ethanol gas etc.
DOT406 Tank Truck
If you have the Flex Fuel Vehicle ( FFV )
Unleaded Gasoline, Diesel, Ethanol, or Natural Gas depending on the engine.
Super unleaded gas is not better for the environment. Super is to be used for specific vehicles.?æIf the auto does not require super, using it will not provide better efficiency or fuel economy.
The only difference in regular unleaded fuel and super unleaded is the octane rating is higher in super unleaded fuel. Burning super unleaded would not cause your vehicle to die.
You would get slightly better distance per volume of the fuel used.
Because it has Ethanol in it. The Ethanol increases the octane and lowers the price.AnswerBecause it has ethanol in it. Ethanol actually decreases the power of gasoline, and subsequently decreases mileage as well. Interestingly, it also makes gasoline more expensive- BUT - this is Iowa, and the government is subsidizing the addition of ethanol to gasoline. In Missouri, where the government does not subsidize, gasoline with ethanol is MORE expensive than its Iowa Counterpart. Long story short, its cheaper because of government subsidies.
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 ! )
Yes you can. Super unleaded gas is just lower in lead so it will not leave as much residue in the system thus giving better gas mileage.
