Fierce competition, unrelenting inflation, high truck prices, and skyrocketing operating costs are forcing many fleet operators to run leaner and keep their vehicles in service longer. To do this requires rigid preventive maintenance and overhauling of worn components. Also, truck component suppliers have recognized the demand for extended service life and are developing new products that are more durable and easier to service. Engine builders are responding to the demand for better fuel economy with low-rpm engines. The low-speed diesel engines are in turn leading to simpler transmissions with greater use of 7, 9, and 10-speed transmissions, compared to 13 and 15-speed gearboxes. Both component suppliers and fleet operators agree that probably the single most important factor in extending the life of mechanical components is proper lubrication, so there is strict adherence to regular oil and filter change intervals by those truck users who want to get long life out of their engines.
