I should have said $4 a tank not gallon. I also don't drive as much as you do Suspect2. I average around 12K a year. Lucky me I guess, my work is about 8 miles away.

The premium fuel thing is no big deal for me anyway I have always run premium in the hotter months in all my Nissan's since 92'.

Look here if you want to see what others are getting as far as fuel economy or lack there of can be. http://www.xterraownersclub.com/cgi-local/ultimatebb.cgi?ubb=get_topic;f=70;t=000158
