75% city driving, some hills, I get 12-13mpg and have a tad over 700 miles on the truck.
Not to flame, but this is a truck. With a v8. And 4x4. If fuel economy was a concern then I'm not quite sure how you ended up with a Titan.
If you needed a truck and had no choice, sure, I can see wanting to save a few bucks on gas if you could. Some quick math...
My G35 got about 17MPG city and took premium gas. My commute is 5 miles each way.
My Titan gets 13MPG. Same commute, cheap gas.
100 miles every 2 weeks.
100 / 17 = 5.88 gallons * $2.69/gal = $15.82 = $0.158/mile
100 / 13 = 7.69 gallons * $2.49/gal = $19.14 (+$3.32) = $0.19/mile
A more average commute of 30 miles each way, highway driving. G35 = 26MPG, Titan = 20MPG. 600 miles every 2 weeks.
600 / 26 = 23.08 gallons * $2.69/gal = $62.09 = $0.10/mile
600 / 20 = 30 gallons * $2.49/gal = $74.70 (+$12.61) = $0.125/mile
Did I cringe at the difference in fuel economy between my G35 and my Titan? A little. Am I worried about it? Not really. For me, it doesn't work out to be a huge difference. If I want to "save" money and come out even on my fuel costs I just skip eating at McD's once.
The bottomline for me is...it is what it is. I more than make up the money I've lost due to worse gas mileage with the money I save on car insurance.
Edit: Instead of looking at pure MPG figures, you need to calculate TCO (Total cost of ownership) and cost-per-mile, taking into account routine maint, car insurance, wear and tear, etc. Once my insurance policy is up I'll be changing carriers and saving $1300/yr. That savings alone is equal to getting over 37MPG or paying $0.865/gal for gas based on 13MPG and 10,400 miles per year. Find me anything else on the market that drops the price of gas so low or increases MPG by 285%.
