72k....yeah....air filter....plugs normal stuff....plus u now have the winter blend gas out so thats a killer

 

air filter gets changed every oil change, doesnt need it but its cheap enough that its good insurance. Dealer claims they dont need tuneup or plugs til 100k, may just go ahead and do it and see. The mileage drop started late summer while the good gas was out, got better and now has gone back down hill. Any other suggestions? I sure did like oklahoma gas that was ethanol free.

 

What year? If an 06 there were some programming upgrades that might be beneficial....

 

mine is an 07

 

So could I date programming to get better mpgs?

 

My wife's did the same thing around 80k. Cleaned the throttle body and all is well. MPGs went back up, so did power.

 

Asked my dealer about 07 and he knew nothing..well, didnt now about 06 either..so..others here though found a factory update that addressed different issues..

 

well I have been getting a consistent 23.7 for the last two months. Had it in the shop Monday, had them put a new filter in, alignment and new shocks and just got back from a trip and 30.1. I also switched gas stations since I had someone check the ethanol content at 18%
