Indeed. From the first refueling, Optimum is able to eliminate particulate deposits that accumulate in the fuel system, as well as an improvement in engine start-up and greater comfort when filling the tank due to its anti-foaming capacity. Our product contributes to keeping the engine clean and in the same condition as on the first day, extending its useful life and reducing fuel consumption and maintenance costs.

We have carried out very rigorous tests that demonstrate the benefits that Optima fuels have on vehicle engines and the results are as follows:

Keeps the engine clean: Optimum incorporates detergent agents that not only help to keep clean those areas of the engine that come into contact with the fuel, but also eliminate existing dirt. It is also a product that remains stable to oxidation by the action of temperature, thus reducing the formation of sediments that can damage the components of the injection system.

Maximum reduction of pollutant emissions: Optimum Fuels allow you to reduce your CO2 emissions per kilometer traveled, compared to ordinary quality fuel.

Reduction of the noise level: Thanks to a higher cetane number compared to conventional quality diesel. Optimum Diesel thus provides greater driving comfort by facilitating engine stabilization more quickly and allowing better starting. Savings in maintenance costs, thanks to the fact that its components, in addition to keeping the engine clean, make maximum use of energy.

Thanks to all these benefits, engine performance is maintained, helping to keep the engine running as it has since the first day.

The age of the engines does not influence when it comes to obtaining all the benefits we have mentioned. It is advisable to make a continuous use of Optimum fuels in order to appreciate all the benefits, as they will clean the engine and improve its performance.

Optimum Fuels will help you to maintain its performance and extend the useful life of the engine thanks to its anticorrosive properties and the use of a product that is more stable to oxidation.

With Optimum Diesel a cleaning of up to 80% is achieved on already fouled injectors. With Optimum Gasolines, up to 88% of deposits caused by conventional gasoline are eliminated.

Yes, Óptima is CEPSA's commitment to the environment, for the following reasons:

• 1. The new formulation contains detergent molecules that control the formation of deposits in the fuel system, keeping the engine clean and contributing to the reduction of fuel consumption and, therefore, of polluting emissions into the environment.
• 2. Thanks to its cetane number improver, it facilitates cold engine starting, reduces noise and vibrations, as well as pollutant emissions into the environment.
• 3. In the case of gasoline, it also contains a friction modifier, which means that it reduces energy losses due to friction of the metal parts of the engine, resulting in higher engine performance, lower consumption and reduced pollutant emissions.
