MPG and cold weather

MPG and cold weather

Postby swervin36 [OP] » Dec 15 2010, 9:47pm

It may be just me but it seems that my truck is loosing 1-2 mpg's since the weather started getting cold. Just wondering if anyone else has noticed this.

Same here, and I am in Michigan where it has been very cold for the past few days. that and 'winter blend" fuels contribute to this.

I'm in NE Pa. and drive into the Poconos every day for work. It's been just a little on the chilly side here too.

you will mostly lose mpg's when its cold out. every vehicle will. they idle a lot higher at start up to warm up so you lose more gas that way obviously lol

Yes it's normal. Between winter blend fuels, cold starts and more slow speed driving.

If you've dropped only 1-2 mpg's, I'll trade you trucks!!! I've dropped about 4. Right now I'm averaging 12.5 - 13 mpg at most and that is extreme conservative driving. I'm trying not to run 4-wheel drive much either unless absolutely necessary. Even with the icy roads, 4-wheel drive is not going to help. Good Luck and be safe out there!

Between the winter fuel, slower speeds and most of us using 4-wheel drive we will all see a decrease. Mine has been going up slowly with each fuel up but last I checked I was getting 15-16 on the HWY. This all assumes i stay out of the throttle....

I've been running in auto 4WD most of the time. We have so much black ice around, it's hard to know when I am going to start sliding. That, the extreme cold, the winter fuel, I am getting about 15MPG right now, which is a loss of 3.5.

I talked to my grandfather that used to haul and fill tanks for marathon oil company and he said the winterblend is a wivestale. Now for deisel there is a winter addative to keep it from gelling but for normal gasoline there is no winterblend. As for getting less milage I could see like others have said about running 4x4 and wheel spin. Plus taking longer to warm up and fighting to stay warm. I have noticed my oil psi even at operating temp is still running a lil higher by 4-8 psi.
