Has anyone really checked gas mileage comparing 10% ethanol to regular unleaded gas over a period of time? I?ve been doing it for awhile now. The biggest variable I run into is the wind, so you need to compare over several weeks or longer. What I have found is that my Silverado generally does about 1 MPG better with regular than with unleaded (that?s 13.5 vs 12.5 with light winds and pulling my boat). Ethanol costs me more per mile.
I don?t have enough data yet on driving with an empty load, so I can only comment on pulling a boat.
Ethanol costs us in at least four ways:
1. Higher cost per mile
2. Cost of taxpayer subsidies
3. Cost of state gasoline tax waiver on ethanol (I assume the taxpayers must make it up by paying more taxes)
4. Higher cost of food products and meat because of higher corn prices.
Yes, I know it?s supposed to reduce our dependence on foreign oil, but it sure looks like we?re getting screwed. Maybe we should go after our own oil harder and give up on ethanol.
