Heavy-duty diesel vehicles that collect and transport waste and recyclables in urban environments, and which work at transfer station sites, material recycling facilities (MRFs) scrapyards and landfills, operate under tough conditions. In these settings, fleet managers are required to maintain high levels of monitoring on specialized vehicles to ensure optimum performance and safety of their employees.
Constantly stopping and starting, waste fleets work in unique conditions where there is often a wide operating temperature range. These varied environments can result in increased engine wear - resulting in unplanned maintenance and downtime. This, combined with heavy loads that further accelerate engine wear, can significantly impact a business' bottom line, where every day a vehicle is down can result in lost revenue. For waste fleet managers, selecting the correct lubrication is crucial for ensuring the protection of vital engine components to prevent unscheduled maintenance and breakdowns.
A closer look at the role of heavy-duty engine oils
Before considering the factors that influence lubricant choice for heavy-duty vehicles, it's good practice to understand the crucial role that engine oils play in vehicle maintenance.
Reducing pumping and spinning losses as well as minimizing frictional losses between moving components, heavy-duty engine oils protect engine components while improving fuel economy and reducing viscous drag.
Supported by the move to lower-viscosity oils, newer engine oils reduce frictional resistance and drag in the engine even further. Simply put, this means that the engine does not have to consume as much fuel or work as hard to provide the same level of power. This allows the engine to run more efficiently and offer improved levels of wear protection, and helps improve fuel economy, which in turn reduces carbon emissions.
