Fuel economy on highway is 25 mpg
My Buick Le saber gets 25 to 30 on the hi way depending how far I drive but around town I get 12 to 18. The reason is short trips the engine does not warm up so your choke automatically kicks in and does not shut down till the engine is up to temperature. Also Short runs means a lot of changing gears so the engine is reving and slowing down for stop lights etc. To get good milage the engine has to maintane a constant even speed.

EPA mileage figures are estimates, and seldom does it have anything to do with the real world, My new car is rated at 19 city and 28 hiway, it gets 22 MPG max. The only thing you can do is make sure the pressure in the tires is correct and run the recommened oil, keep the car in good running order.

CHANGE YOUR AIR FILTER!!!! INSTALL A PUEROLATOR OR FRAM AIR FILTER FOR THE MODEL YEAR OF YOUR CAR. I DID THAT FOR MY 2007 CAMRY AND I PROBABLY PICKED UP 3-4 MPGS. THE TOYOTA FILTER MIGHT BE TOO RESTRICTIVE!!!

Hello;
Looks like the coolant temp sensor for the ecm has started to go out. Test and replace, clear codes and should be ok.
Thanks;

Sounds like you might have an oxygen sensor problem. Your catalytic converter(s) maybe defective or dirty. That in turn can dirty up the oxygen sensor. A defective oxygen sensor will send faulty info to the computer, interpreting the fumes as cold (even when the engine warms up). That causes the computer to adjust the fuel mixture to very rich, giving you poor gas mileage and the fuel smell. Hope it helps.
