In recent times, awareness of our collective impact on the environment has increased demand for fuel saving initiatives. In fact, many countries have specific plans to reduce the rate of fossil fuel consumption in heavy duty vehicles.
However, it’s not just the environment that will benefit from these changes.
Fuel is one of the leading operating costs for heavy duty trucking fleets – often accounting for 30-40% of your overall costs – and even small decreases can have a significant impact on your bottom line.
Switching to low viscosity engine oil is just one of the ways you can reduce your overall fuel consumption.
How do low viscosity engine oils work?
Lower viscosity engine oils reduce viscous drag on moving parts and enable oil to flow more efficiently through the engine, which can improve fuel economy. The results are even more impressive in colder climates, where lower viscosity engine oils can reduce the time it takes for engines to warm up.
The new standard
PC-11, the next American Petroleum Institute (API) commercial engine oil performance category, is now known as API CK-4 and FA-4 performance categories. This new category has placed a heavy focus on improving fuel economy.
Many Original Equipment Manufacturers (OEMs) are already benefitting from fuel economy focused products. In fact, in 2013, Kenworth announced it would use SAE 10W-30 oil as its standard factory fill for new Class 8 diesel trucks. Many other OEMs, such as Mercedes-Benz, Volvo, Detroit Diesel and Cummins now also recommend or have allowed lower viscosity grade oils, such as SAE 10W-30 and 5W-30.
SAE 10W-30 and SAE 5W-30 engine oils have demonstrated fuel economy savings and are available today without significant capital expense.
