Maintenance programs can reduce average fuel consumption rates by ensuring that vehicles are tuned for optimal performance. The potential for fuel savings and emissions abatement may be as high as 5%. Improving the way vehicles are maintained can also increase their resale value. 1
The use of low-viscosity lubricants in maintenance programs can reduce friction and energy losses. The combined effect of low-viscosity synthetic engine oils and drivetrain lubricants can improve fuel economy by at least 3%, saving nearly 2,200 litres of fuel per year for a typical combination truck. 2
There are regular formal maintenance checks that drivers should carry out, such as monitoring tyre pressures. Truck tyres inflated 10 psi below recommended air pressure levels can lower truck fuel efficiency by 0.5% to 1%3 by increasing rolling resistance. Under-inflated tyres can also increase tyre wear, create irregular tread wear and reduce casing durability.4 Regular monitoring by drivers can generate instant savings. Automated monitoring and tyre-inflation systems are also available.
