as far as I know I always filled up with the 87 unleaded gas, where are you guys getting all this Ethanol, no Ethanol gas ? not sure if I ever even heard of such thing..... unless its the normal gas and I am just confused.

 

Alot of gas now has some ethanol in it, next time your at the pump look around for a small sticker that says some thing like "may contain up to 10% ethanol".

 

at 75 mph on the interstate I have never broken 16.5mpg
13.5 in city

dealer said I would need to keep a driving log for 30 days before they can even help
does anyone get gas mileage like me at all?

 

Another thing to watch out for is idle time. My 07 mustang GT has a gas mileage meter and I took it down to Atlantic city (100 miles) and was getting 27MPG (being very light footed). I pulled in for a car wash and after 15 minutes of idling with the AC on I was down to 17MPG for the trip!

Another note is coasting down hills and not accelerating towards red lights. In my mustang I can get 35 MPG if I put the clutch in going down hills on my way to work but normally I get 22 MPG.

Its hard to tell whats going on in my H3 since it doesn't have real time feed back but the principles still apply. My first tank is 18MPG but I have not tried a full highway trip yet.
