John is aware that competition is great within the industry and any slight advantage over his competitors is worthwhile. How can he improve fuel efficiency?

Explanation: • By pulling high-cube trailers whenever possible: No. A high-cube trailer will be higher and present a high, flat face to the air thereby increasing fuel usage.
• By under-inflating his tyres: No. this will increase drag and adversely affect fuel consumption.
• By holding on to the lower gears for longer: No. doing this will mean the engine is running at higher RPM for longer - and will cause a reduction in fuel efficiency.
• By fitting low-rolling resistance tyres and fitting a roof air deflector to his cab : Yes. these steps could improve fuel consumption by reducing energy losses from the tyres and by improving the aerodynamics of the vehicle.
