Best fuel economy I ever got towing, was my 6bt cummins after I installed fresh injectors, rebuilt the turbo and adjusted pump timing+bumped up fuel pressure.
I got 17 mpg, towing a 20 ft twin axle trailer full of 30 windows, steel roofing and tounge n groove flooring. A Toyota engine gives that type of fuel economy towing NOTHING.
Fkn Toyota fan boys, I used to be one of yas.
Best cold start was 57 below zero while the coolant looked like a green slushy: 6bt cummins.
