89 and 93 octane isn't the right argument.
You need to ask why does gasoline contaminated with ethanol still exist, when all it does is increase the cost of gasoline (per mile), decrease mileage (per gallon), and increase emissions (both per mile and gallon).
Drivers would save tons of money if they'd refuse to buy it, we would just need to get enough of us together to get such a thing done.

- DiabloD3 8y agoIt lowers actual octane rating, thus increasing air pollution ever so slightly. An engine designed entirely for ethanol, not one that just merely takes a mix but is meant for gasoline, would be higher efficiency and be worth it.
- laurencerowe 8y agoEthanol has a higher octane rating (113 RON) than petroleum, but is less energy dense (so lowers mpg.)
- dragonwriter 8y ago> You need to ask why does gasoline contaminated with ethanol still exist The two mandates that together promote this are mandates for share of renewable fuel use and mandates for gasoline oxygenation to reduce carbon monoxide emissions; ethanol-containing gasoline helps meet both mandates (the latter is applicable to certain markets at certain times of year.) > Drivers would save tons of money if they'd refuse to buy it, Well, yes, refusing to buy the gas that is sold at the pump would save lots of money.
