I have a 2001 SCrew and have had the truck for a little over a month know.

When I first got the truck the fuel milage appeard to be a average with everyone else 14MPG. In the last month it has dropped to about 11MPG. Is there some pointers you all can give me as to why it would change so quickly??

 

computer adjusting for cold weather

 

Is that something I do or does it do that automatically?

 

the colder it gets the mpg go to poo. the computer richens the air-fuel mixture because the air is more dense. nothing you can do

 

also the gas station might have swapped blends, summer to winter blend, try a different gas location, but get used to the bad mpg

 

Thanks fellas...I will try a different station.
