A challenge, such as the Dakar, stands for toughness and highest demand and it is an excellent testing bench for Repsol lubricants and fuels that have already shown their efficiency in high level competition achieving world championship titles in several classes of Road Racing World Championship. The Dakar is, as all fans know, the hardest test for drivers, riders and mechanics and requires the use of specific products to guarantee the highest reliability.
Under these extreme conditions, where engines often have to perform at the highest level for very long periods of time, it is fundamental to protect them with lubricants adapted to these conditions, having to provide:
Highest protection to the most needed mechanical pieces, such as pistons and the crank and connecting-rod bearings.
High detergency to avoid the formation of deposits in the segments and thus keep the engine compression throughout the race.
Adequate viscosity and a high viscosity index to guarantee lubrication under the most extreme heat and cold conditions.
Specific additives to avoid premature wear due to the heavy dust and sand covered areas.
The experience of a group of experts such as the team at the Technology Centre Repsol YPF has established in Móstoles (Madrid) can set the difference.
With regard to fuels, regardless of obtaining high performance in all uses, it is fundamental to guarantee the engines cleanness during the whole race. The following criteria are set-up:
Use of refinery currents obtained from state-of-the-art refinery processes.
Inclusion of state-of-the-art multi-functional additives to keep all admission systems clean, especially valves and injectors.
Minimising deposits in combustion chambers to avoid abnormal combustions.
