Scania R470 Fuel Consumption

i run a scania r470 and before that i ran 2 other 470’s and i regularly get 10mpg round trip, at the moment i’m running mostly around 6 ton and am getting over 11mpg.
if your heavy out and empty back you should get 10 if you have your truck set up right.
i have a low height fifth wheel which keeps my trailer height down a few inches, i regularly check the tyre pressures and run at 110psi on the drive axle and 127psi on the steering axle, i also have the crossfire system fitted to my drive axle which makes keeping my eye on the tyre pressures easy and putting air in even easier, i also carry an airline which i can use from the air tank supply under the grill as most of the air lines in the uk only seem to go to 80 psi.
