Truck drivers and fleet managers make difficult decisions every day, from the route they take, the speed at which they drive, to how they choose to manage and track their vehicles. These decisions can be informed by drawing on operational data and experience. When it comes to investing in new trucks based on alternative fuels, it鈥檚 not always possible to draw on this data and experience, especially when you consider the dynamic marketplace and wide range of options available. A range that will certainly be needed given the drive towards decarbonisation coupled with the maturity and availability of the hardware and infrastructure solutions available.

With demand for road-transported goods predicted to triple by 2050¹, potentially leading to there being 80 million heavy-duty trucks on the road opposed to just 45 million today, it鈥檚 clear that these alternative-powered, lower-emissions vehicles are likely to play an important role in the industry鈥檚 future.² 

Much of the transition to alternative fuels is helping the industry to meet the decarbonisation challenges and targets head on through the development of new powertrain technologies that offer lower-carbon alternatives to traditional diesel internal combustion engines (ICE).

While Karin Haumann, Shell Product Application Specialist for Heavy-Duty Engines in North America, agrees, she also suggests that the route ahead won鈥檛 be entirely straightforward:

鈥淣o single truck manufacturer will be placing all their efforts on one technology alone, meaning there will be a mix of options depending on the application. It will then come down to a case-by-case decision by the customer on what to buy, considering the investment required, available infrastructure and the suitability of the technology for individual business operations e.g., those making long vs short-haul journeys.

Here, Haumann touches on one of the most important aspects of the transition facing road transport: infrastructure. As such, to capitalise on the emergence of these new technologies, the whole industry ecosystem must keep pace. Fleet operators must be clear on the benefits and potential blockers of each option available. For example:

Though these sustainability benefits understandably play a leading role in the fuel switching decision process, they are not the only consideration.

鈥淥ne of the most prominent things that is driving the customer at the fleet level is the cost of fuel. It can be their largest expense, so they will always be looking at options available to them through a lens of reducing that expense,鈥� suggests Haumann. 鈥淭hat could be something as drastic as buying an electric vehicle and all of the things that go into that, such as installing charging capabilities, or it could be as simple as exploring the impact of low friction tyres or aerodynamic trailer configurations.鈥�

Fortunately, one way to keep costs under control is to ensure the right lubrication is in place to help unlock the full potential of these fuels.

However, while industry awareness of the expanding fuels mosaic is increasing, perhaps less well known are the lubricant variations and specifications that must be considered to get the most out of these engines and fuel types, for instance:

Thankfully, the picture is a little clearer in that regard, as Haumann explains: 鈥渨hatever the application, the right lubricants will be there, so lubrication will not be a blocker to progress.鈥�

What鈥檚 more, the technology is developing at a rapid pace. In terms of electrification, for example, the industry is developing new lubricants for the second and even third generation of electric powertrains, which might require new products due to different designs.

鈥淲hat drives the customer at the OEM level when it comes to lubrication are the regulatory requirements,鈥� Haumann states. 鈥淭hey are under pressure to design more efficient engines, and one of the requirements of that is lower viscosity engine oils. Minimising friction from the engine by utilising the lowest viscosity oil is a huge incentive.鈥�

For instance, when new platforms are developed and a lubricant is needed to meet its specifications, OEMs typically start with what went before and then, as development occurs, modify certain elements. LNG or CNG is a good example, given there is now a different specification for natural gas engines due to the different needs of the lubricant in this case.

There are regional differences that dictate the pace of these developments too. While European fleets are generally used to lower viscosity oils, having recently introduced 0W-20 and 5W-20 grades 鈥� thanks in part to regulatory developments like , the European Commission鈥檚 mandatory simulation tool to determine CO₂ emissions and fuel consumption from heavy-duty vehicles with a gross vehicle weight above 3500kg 鈥� the US is more likely to use 15W-40 engine oils. 

With that being said, the US market is in the midst of an engine oil specification upgrade industry wide, with regulations due to be implemented in 2027 that will require an increase in efficiency from the engine alone. 

Today鈥檚 decarbonisation efforts are arguably making the road freight transport sector a more dynamic space than ever before, with the development of a wide-ranging, lower-carbon fuels mosaic having knock-on effects for other important areas like lubrication.

As these developments continue to evolve, while at the same time operational costs and conditions change, it will be increasingly important for fleets to work with trusted experts. Shell Lubricant Solutions, for example, has the breadth, scale, and first-hand experience to recognise specific business needs and provide advice on how to succeed, both today and tomorrow.

鈥淥ne of the best things about the dynamic nature of the road freight transport sector,鈥� Haumann concludes, 鈥渋s that we get to work with OEMs throughout these development stages, effectively co-developing the lubricant to ensure that any unique needs of the oil are met.鈥�

And it鈥檚 exactly this level of collaboration that will make the decision-making process easier for fleets, as they look to take the next step in their decarbonisation journey.
