+30 years tracking fuel efficiency, I have always seen around a 1 mpg drop during the cold winter months. This year I’ve seen no drop in fuel efficiency this winter, why? Improved low viscosity lubricants, improved fuel treatment chemistry, improved aerodynamics specific tractor trailer gap, improved rubber compounding used in modern low rolling resistance tires, and improved weight biasing non torque reactive drive axle suspensions that significantly reduce slip in cold slippery conditions.
