Fuel efficiency is a significant consideration in the design of heavy-duty trucks, as it directly impacts operational costs. Manufacturers continuously innovate to improve fuel economy, with advancements in engine technology, aerodynamics, and weight reduction strategies. Additionally, many heavy-duty trucks now comply with stringent emissions regulations set by environmental authorities, incorporating technology such as selective catalytic reduction (SCR) and diesel particulate filters (DPF) to minimize harmful emissions.

The primary function of engine oil is to reduce friction between the countless moving parts within the engine. This friction, if left unchecked, can lead to wear and tear, resulting in costly repairs. Engine oil not only lubricates but also cleans the engine, preventing the buildup of sludge and varnish that can impede performance. Additionally, oil helps in sealing the gaps between pistons and cylinder walls, preventing combustion gases from escaping and optimizing engine power.
