Re: Gas mileage
22mpg isn't bad for the 3.8L V6. Fuel economy is a bit vague only because everyone, providing the vehicle is similar year and power train, depends on overall weight (passengers/cargo), speed, and if it's been properly maintained. If you don't need the other seats, leave them at home and pump up the tires a touch.
Ethanol is everywhere in Ontario here. There's no avoiding it and they claim it takes so many vehicles off the road each year. I'm sure they had a good reason to add it, but keep in mind the concentration of ethanol is really in the 3-5% range. NOT the 10% that's advertised on the pumps - it's just a marketing ploy.
Most vehicles produced that aren't built to handle ethanol E20 or greater, can't handle more than 5-6% (max) of ethanol content as the vehicle isn't designed to run it, let alone a high concentration.
Even with the e-gas here, my 3.0L taurus weighs in at nearly two tons base weight and still manages 25-30mpg on highway trips (55-65mph).
