Cold weather MPG sadness

Think of all the extra resistance there are on cold turning bearings and cold thick oils among other things such as blowing head winds and idling to stay warm to name a few.

 

In off road conditions, the crossmember bolts get loosened up. BEfore retightening, take those out and replace them with fine thread flange bolts class 10.9 or grade 8. Say goodbye to a boring life

 

I've seen on here in several places that the winter blend fuels will cause a .5 or more mpg decrease. I actually just asked this in a different thread and someone posted that mpg will rise in the summer due to the fuel mix. Kerosene was also mentioned there. The post is in ask an owner operator under poor fuel mileage.

 

Due to a mix of # 1 and # 2 diesel. The more #1, the colder you can go but MPG goes down. Beats gelling up.

 

This is the correct answer. I used to deliver diesel.

 

Mine usually tanks .5 to 1 mpg in the winter. I track my fuel tank to tank - last 5 years, religiously. Never fails.

 

Yeah kinda sucks all around. Winter fuel is less efficient, but hopefully your bunk heater will off set that. Summer fuel gets better mileage, but you may see more idle which off sets it. ####'d if you do, ####'d if you don't.

 

I got 2mpg running thru a nice 40-50 mph headwind in south dakota last weekend . Had the pedal on the floor and couldnt get it out of 11th gear .

 

It stays 4.5mpg year round. Just start hauling 120k gross and you won't even notice
