increases are possible by friction modification. This translates to a huge contribution in vehicle parc fuel savings and CO2


reduction.


Acceptance and adoption of high efficiency, low viscosity and durable lubricants is becoming more widespread. In Europe, SAE 5W-30 lubricants at 3.5cP HTHS viscosity have displaced the commonly utilised grades of SAE 15W-40 or 10W-40 in factory fill engine lubricants for new commercial vehicles. Several OEMs are now looking to take this a step further and are utilising SAE 5W-20 and 0W-20 lubricants at 2.6cP. Lubrizol studies demonstrate that utilising a SAE 5W-20 lubricant instead of SAE 10W-40 can save up to 1,900 MT CO2


with durable and efficient lubricants. However, servicing of the vehicle provides multiple choices for the quality and viscosity grade of the lubricant that can be used. Commercial vehicle operators may place greater value on convenience and lubricant cost as opposed to environmental impact and CO2


efficiency.


Conventional viscosity grade lubricants can still be used rather than more efficient oils which provide tangible efficiency benefits. Ideally, the same quality and viscosity of fluids should be used for certification, initial fill, and service fill of the vehicle throughout its life. The use of lower quality fluids for ageing vehicles should be discouraged.


per annum for


a fleet size of 1,000 vehicles. This is the equivalent annual carbon footprint of 290 average European people. If all lubricants used for on road applications in Europe were to move to an SAE 5W-20 at 2.6cP HTHS viscosity, the total annualised saving could be 11.2 million MT CO2


in avoided emissions.


What more can be done to enable the commercial vehicles of today and tomorrow to move cleaner?


New commercial vehicles are first filled in the factory


Now more than ever, the lubricants industry needs to demonstrate and clearly communicate how it can extract maximum efficiency from the commercial vehicle powertrain of today and tomorrow. Durable and efficient lubricants with low HTHS viscosity are readily available and effectively allow for tangible efficiency benefits and proven performance in the field for commercial vehicles.
