factoring the weight of fuel and you.

OK, dumb question here: Don't the tank heaters keep the fuel from gellin even in subzero weather? Or don't you have tank heaters?

I've got a few years of trucking under my belt, but I've never had to run midwest or up north in really cold weather. I've been around zero many times, but to my knowledge never much below that for any length of time.

 

many of the newer trucks don't have fuel heaters anymore. they use the fuel to cool the injectors so the fuel returning to the tank is hot. The switch on the dash for fuel heater is actually a fuel filter heater. the only real fuel heaters have valves on the motor that need to be turned on just like the heater core. Older mechanical motors need these as the returning fuel is cold.

I've have many many loads, in fact the majority of my loads when I was running produce were so heavy I could only take on 50 or 100 gallons of fuel.

 

Summer blend diesel weighs 6.9 lbs to the gallon. Winter blend diesel weights 7.2 lbs to the gallon.

I am out of the game, now. I was out there when weigh-in-motion scales were installed. Before that, some scales consisted of four platforms that could be totaled for the gross. The driver was instructed to "split the tandems". Most of us had to almost stand up to see the crack between the two drive axle scales in our mirror. When the drive axles were split correctly, the steer axle and the trailer were in place on platforms of their own. You can imagine what a back-up this would cause with today's truck traffic.

 

Thanks for the info both Brickman and MedicineMan.
