I have a 2006 Chevy Silverado Z71 that can use regular unleaded or any of the ethanol mixtures. I noticed fuel economy is not very good with the ethanol, so I decided to try some hypermiling techiniques on a trip I made. I wanted to keep things simple, so the only things that I concentrated on was keeping the tach below 1,700 while accelerating and going up hills and I would also put the truck into nuetral when going down hills.

I normally get about 17 mpg with this vehicle. On the first leg of the trip, I had heavy headwinds (30 mph with gusts to 50) and was driving through rain most of the way. On that leg, I was able to get just shy of 20mpg. The next day was calm with no water on the road and I was able to get 25 mpg with this vehicle.

I thought this was pretty good for a truck with available 4WD and a 327 V8.
