I have a 2008 Prius. We bought it new and have 40,000 miles on it. Our average gas mileage in the winter is right around 42 and about 37 in the summer. We live in the southern California desert and right now everyday is about 110. This is the kind of mileage the car has been getting from day 1. I was just wondering if this is normal with high heat climates. It seems a little low to me. I change the oil every 5 thousand miles with full synthetic oil, I change the air filter and I have pirelli p5 cinturato tires. Other than that nothing big has been done. I'm a very conservative driver and rarely if ever mash on the gas. Any tips, tricks, or recommendations?

Google Hypermiling, but check your tire pressures and put them at 40 PSI all around, remove any unneeded weight.

Well I guess the car doesn't like me talking bad about her. Since I posted this I've been averaging 28 mpg. Does anyone else have similar performance in really hot humid places (110+ with 40%+)? Should I take it in?
