Re: Help! Starting to HATE my new SRX :-(

With highway diriving, you should get better fuel mileage. I get around 18 at 75 mph. I've found that about every 5 mph I change from there, it goes up about 1 mpg until about 45 mph, where it tops out around 24/25mpg. It definitely sounds like an air leak. I had one when I first got mine as the rubber coupling that connected the MAF to the intake manifold had come off on the bottom so air was leaking in past the MAF, so I was getting a "too lean" code. I am pretty sure I caused it when I was messing around with the air filter. Obviously there is no way of know what your vehicle has really been through, but I bought mine used with 40k miles on it, have put another 40k on it since, and have never had a problem with it. Good luck!

PS. I forgot to mention my wife now drives the SRX and she gets around 14.5mpg in the city. When I drove it, I got around 15.5 in town.
