Awesome mileage for your trip, Tony! Too bad your city mileage suffered while you were there. I get about the same as you regularly see in the city. I see about 27-29 for my commutes through the metro Phoenix area. The lowest tank I've ever seen was 22, but I think that was a combination of filling up too early as I think I only put about 90 miles on the car before filling it up that time. So the error may lie in the inaccuracy of when the fuel service station pumps decide when to 'click' off.

However, driving around metro Phoenix isn't quite like driving through metro New York. I'm sure my mileage would take a hit up there.

Any reason why you use 5W-30? I've been using 5W-20. Luckily, both my vehicles take it, so I get it in bulk.
