    Does any one else's fuel mileage drop? I have an 06 Volvo with an isx Cummins, I noticed yesterday it was in the 40s and my dash said I was averaging 7.8 today with the same load same terrain lower 30s high 20s I can't get out of the 6 range. Now the sad thing is my dash average is high so that 7.8 was really 5.7 so that meens my 6.3 is probably ouch. If it is the cold weather doing it is there any way to help it? Maybe blanket the front end like I see some trucks? Thanks for everyone's cents put in.

    Head wind and A tail wind will make some difference.

    Low temp has many things that it brings with it that a winter front won't help. Thickness of the air, usually wind too. Diesel runs less efficiently in colder temps.

    Cold trans and diff oil is thicker. Some cold days with a light load the gauges won't even break 100°.
    Cold air is more dense, harder to push through.
    Tires colder, so less flexible and less pressure.

    Fuel is also a crap shot. The farther north you are the more Kero it probably has in it.
    In the northern states in jan- feb it can be as high as 70%. Kero is good for cold weather fuel problems, but hurts mpgs......
