So I just went to the gas station because my low light came on at 164 miles.... I thought it was BS, or either someone else was syphaning gas out of my tank because now I am getting 10 mpg.... This fricken sucks, I have no idea what can be causing such ****ty gas miles. Air filter has been changed, spark plugs seem fine, wires were changed last year. The only thing else I can think of is I have remote start on it, but I dont let it run no more than 10 mins before I drive it. I do know that cold air will have an effect but before I was getting 16-18mpg and I was complaining then...

 

Carbureted or FI.

 

What,!? what does that mean!?! hehehehe jk I have Fuel injected

 

Making sure,you never know.
When was the last time the fuel filter was changed,same with 02 sensor.

 

Everyone will notice a small drop in fuel economy in the winter months because of the way that fuel is mixed diferently in the colder months. On top of that if you idle your truck for ten mins. each morning thats right at a hour a week. I don't think that this is making the 6 MPG difference that you are seeing but it isn't helping either.
