Ethanol only makes more power if you're running a higher compression or boosted engine that can take advantage of it. In your standard flex-fuel engine it will make less power with worse mileage. GM had a few turbo Saab models they released that could detect when you were running on E85 and up the boost and adjust the timings accordingly to make more power on it. In our trucks I would stick to gasoline, no sense dumping more money on something that nets you no benefit.

 

i love the water/meth in my diesels...lots of power, but in cali...if its cheaper, its not going to be any better, if that makes any sence?my thoughts anyway

 

how do i use the over head display on my 2001 dodge ram truck

 

I figured why the puter is inaccurate. The mileage from the analog odometer from fill up to fill up is not consistent with the millage of the puter digital readout. I never realized this until I had suspected my MPG was actually lower then actually analog odometer calculations. So my truck is getting even worse millage then I always believed was really poor already using the trip puter. I'm actually averaging 15.2 mpg. Hell at that rate I could be driving a Ford F-250 diesel and have less of a fuel bill.

 

I just checked mine last tank. It was accurate to 4/100ths of MPG
