Reducing consumption throughout the vehicle’s operating life

Even if it is well set up, well driven and well monitored, a truck also has to be well maintained, and this must be done employing the Renault Trucks network’s know-how and experience, and you must also obtain the latest technical innovations (Optifuel Retrofit) in order to maintain its fuel efficiency throughout its entire operational life.

Optifuel Retrofit
In order to allow its customers to benefit from solutions designed to reduce consumption that can be applied to their entire fleets, Renault Trucks offers a service called Optifuel Retrofit. This involves installing the latest fuel saving options on trucks that are already operational. For example, the Optiroll pack can be installed as an aftersales feature. By taking maximum advantage of the vehicle's inertia and the "controlled freewheeling" function, Optiroll can reduce consumption by around 1%. Similarly, it is possible for the power mode to be deactivated on a vehicle already in service, just as the automatic engine cutout can be installed. Finally, Optifleet, the Renault Trucks on-board fleet management IT solution can also be installed as an aftersales feature.
Furthermore, maintaining vehicles in line with Renault Trucks' recommendations, using the manufacturer's original spare parts and the range of Fuel Eco lubricants from Renault Trucks Oils, can enable customers to reduce their total fuel bills by a significant amount. The specific formulae used for these lubricants based on low viscosity and friction modifying additives combine to reduce overall friction and therefore consumption.
All these possibilities are ways of enabling vehicles already in service to enjoy a second lease of life.

Optifuel Workshops (France only)
Even when it is well configured, well driven and well monitored, a truck still needs to be well maintained to preserve its low consumption performance throughout its lifetime. To meet this need in France, Renault Trucks offers a service known as Optifuel Workshops (Ateliers Optifuel). These can carry out a number of different interventions to reduce the consumption of trucks already on the road and enable them to take advantage of the latest advances in this field.
First of all, in order to determine the action to be taken, technicians from the Renault Trucks network download data from the Optifuel Infomax software's consumption measurement and analysis tool to find out why excessive quantities of fuel are being consumed. Following this, a number of different measures can be implemented.
In particular, these concern adjustments to the chassis and engine. The Renault Trucks technicians first of all adjust the vehicle's geometry and then the rocker arms on the engine. Depending on the vehicle in question, they may subsequently suggest fitting specific fuel saving tyres to the customer as well as installing and appropriately adjusting deflectors. But the services provided by the Optifuel Workshops go even further and can incorporate the possibility of adding the latest technical innovations designed to further reduce fuel consumption as an aftersales feature.


Reducing fuel consumption is not something to be improvised or imposed. A precursor and leader in this field for many years, Renault Trucks has a global approach to this issue embodied in its Optifuel Solutions.

In order to achieve substantial and sustainable results in this area, Renault Trucks recommends users to correctly configure their vehicles, particularly their mode of propulsion, train their drivers properly, carefully measure and analyse their consumption and then optimise their fleets by regularly maintaining and updating them.

Optifuel Solutions are one of the cornerstones of Renault Trucks' All For Fuel Eco approach, which aims to mobilise the energy of the manufacturer's entire workforce, from the design stage right through to vehicle sales or repair. As a result, it will be possible for customers to be offered concrete and efficient ways of continually driving down their fuel consumption.
