I have been getting AT LEAST 700 miles per tank for months. My average F/E has been over 43MPG. I find that the F/E shown times the tank capacity is a very accurate indicator of cruising range. I can count on about 100 miles more after '0' on the cruising range.

The disturbing part is that the low fuel light is on, and the guage is WELL below 'E'.

I run 0W-20 and have a mostly highway commute of 96 miles daily.

Good Luck!
