Well i broke the 14mpg mark this past week. I think this may be due to the fact that it is starting to get warmer in NJ and i only let it warm up for 30 sec or a minute before i take off in the morning. I took it to the dealer a few weeks ago for a free oil change, so i had them check it out to see whats the deal is with the mileage. The said that it is normal due to the ethanol they put in the gas in the winter. Thats definitely BS. I don't know what im gonna do with this thing...its a nice truck but this really pisses me off. Glad i kept my old taco!
