I live in Minnesota, and the last two summers averaged around 34 mpg. Last winter I averaged 30 mpg, and it seems like it will be the same this winter. Tire pressure comes out fine, and my driving patterns haven't changed. I do spend a lot of time at higher RPM's though, as it takes a good 5 minutes for the cold engine light to switch off and overdrive to kick in.

Is this something normal for winter driving, to see a mpg drop? Thanks.

 

yes colder air is denser so you use more fuel. plus all the warm up times and such.

 

Have u tried putting nitrogen in ur tires?

 

I fully understand why you would want to put nitrogen in your tires...but how would I go about doing that? I'll have to ask next time I go in for fuel.....lol.

 

Tire rotation places r good ,tire places also

 

Simply using nitrogen in your tires is not going to offset the loss in MPG due to changes in temperature/fuel composition.

Something else to take note of is the increased ethanol content of fuel in the winter months.

 

Tru,but it will make sure u got stable pressure .I have done of my own choosing to fill my tires up with 38 p.s.i. instead of the drab factory 29 p.s.i. that Toyota suggest.I have the Bridgestone Potentza's on my Scion that have a max p.s.i. of 44.I have chosen to increase my mileage by filling them up with nitrogen instead of air to 38 p.s.i to give them some stability and not 44 p.s.i .to not overinflate them causing distrasterous control issues.Now 38 p.s.i. is my personal choice. Most shops reccommend 35 p.s.i. and say 38 p.s.i. gives a bumpy ride but ,I have found it not so.
