i have flexfuel on my yukon xl and i have to disagree, while i was in illinois gas for regular was 3.21 and e-85 was 2.69. also even though i burn it faster i get a HUGE tax cut on it also i saved 2000 this year because of owning a flexfuel truck.ewillie1 said:Clearly the Acadia is not set up for E85 and could harm the engine. We have a fleet of '07 Impalas here in Ohio that are Flexfuel and have the badging on the trunk. I am pleased that we suport local farmers, but experience significantly lower MPG on E85 due to the lower energy in each gallon. Cost is the same, so you have to make your argument to use based on reduced dependence on foreign oil, which is certainly a positive.
At any rate, not an option for our Acadias at this point. Erik
I agree with your thoughts. I traded in a '03 Tahoe 4WD for my Acadia and ran E85 for several weeks before the trade and found the MPG was significantly less than when using 87 octane. The cost differential between E85 and 87 octane would have to be on the order of $0.50 to $0.75 per gallon for all things to even out. The differential in Houston was only $0.30 and with the reduced MPG it did not pay to use E85 (except for my contribution to the enviroment) :cheers:coloradoGM said:I think E85 in Denver is around 2.40 a gallon so it would be way cheaper than regular. You do get worse gas mileage so you would have to calculate the savings based on MPG.
Also, it's not that the engine wouldn't run on E85; the difference is that Ethanol is very corrosive and would eat the fuel lines and tank. Then engine will adjust for the change in fuel but E85 capable vehicles have plastic lined tanks and fuel lines to prevent corrosion.
