If you live in an area where it gets cold in the winter, be prepared for lower MPG. When the engine is cold, it uses more gas. Winter gasoline is blended in such a way that it gives you lower MPG. You can't do much about those things, but you can keep an eye on tire pressure.

As temperatures drop, so does tire pressure. When colder weather comes your way, check your tire pressure. You'll have to add air. Driving with softer tires uses more gas.

You can use an engine block heater to let the engine warm up quicker, but the cost of electricity will negate any savings at the pump.

 

Thankfully I'm in Texas, we still haven't been consistently under 90!

 

That's a bit too warm for me. We had a relatively cool summer - seldom in the 90's.

 

From Wisconsin - my 2011 Fit lost about 5 mpg during the below 20 degree months. Expecting the same from the 2015.

 

Leaving it running overnight will do that.

 

winter? whuzzat

 

Oh, don't worry, it's a bit warm for me as well, just saying, we don't really have to worry about low MPG, except in Summer when we have to blast our AC.

 

Yep, It definitely goes down a few MPG in winter...

Shokan, NY!! Real close to an old stomping ground of mine... Lived off Maverick Rd in Woodstock back in grade school!

 

Let's look at that. Tire pressure is proportional to the absolute temperature. Let's say you set your pressure at 32PSI on a day when it is 70F out and then the temperature drops to freezing. In absolute terms, the temperature went from 530R to 492R. Pressure drops proportionally so it will drop to 30PSI! It is a pressure drop that should be corrected, but it isn't like the tire is going flat! You experience a much greater pressure change when the tire warms up from rolling which is why they tell you not to bleed pressure from hot tires.

I should check my pressures. It only got up to 85 here today.

 

It's best to air up after all the tires have been sitting in the shade for awhile, long enough after driving for them all to cool down. If you air up tires sitting in the sun, they'll be lower in pressure than the shaded side once out of the sun.

 

You should only air them up after dark, when the outside air temperature is 68F, atmospheric pressure is 29.92 inches and only on a new moon....

Let's not get silly here. Most tire problems are caused by underinflation. As long as the tires are at the specified pressure before the car is driven you will be fine.

 

You moved away from a beautiful area.

I see your two white Fits. We almost wound up with two silver ones, for lack of choice. It's bad enough keeping track of two Fits, let alone two of the same color.

 

<OT> Hey, it's quite nice here, too. Living on the Salish Sea (aka Puget Sound/Strait of Georgia) with Mount Baker on the horizon... You won't hear me complaining!
