I just got back from an exhaustive 9 day 3,426 mile trip to Florida from NY and various places in-between. I thought this would be the perfect time to gauge the actual gas mileage I'm getting on my '06 Element 4wd EX.
Note: Car is tuned up, no external mods (for draft), and all gas used was name-brand 87 octane for the entire tankful with non-stop driving (except for restrooms). I only used complete fill-up -to- yellow fuel light "on". I also let the pump stop automatically (no topping off). Ethanol was not taken into consideration.
1. Using the AC on the highway costs me 2 MPG
2. Going from 80 to 85 is very inefficient
3. 70-75 seems to be the "sweet spot" which just so happens to co-inside with the maximum posted speed limit of 70 in most places.
4. Doing all this kept me sane when driving alone.
It figures AFTER I post I come across a better place for this thread.
Sorry Mods, I know you'll probably "move" this
