Discover the three-in-one power of TotalEnergies' premium fuel

Excellium's true strength lies in its rigorous selection and precise dosage of three main additives:

up to 99% less deposit build-up
up to 38% less friction
class A protection

Anti-deposit

With its enhanced cleaning power, Excellium is even more effective: it fights grime, preventing up to 99% ¹ of engine fouling. It also eliminates existing deposits that can impair engine performance.

Wear-resistant

With its lubricating power, our premium fuel reduces friction between the engine's metal components by up to 38% , thus reducing the risk of wear on sensitive parts in the injection pump, which can extend engine life.

Anti-corrosion

Excellium protects engine components against corrosion 3 by preventing the development of rust in the presence of water (condensation, rain, sea spray, etc.).

1 Excellium helps prevent up to 99% of fouling in a petrol or diesel engine, compared to a fuel without specific additives. Tests carried out by an independent body.

2 Excellium reduces wear on parts in a gasoline engine by up to 38% and enhances the lubricating properties of diesel fuel compared to fuel without specific additives. Tests performed using an internal method.

3 Excellium has an A performance rating for corrosion protection in gasoline and diesel engines compared to non-specifically additive-treated fuel. This corresponds to the highest level according to the international NACE (National Association of Corrosion Engineers) rating system.

Excellium cleans your engine for tangible benefits!

The quality of TotalEnergies' fuels is a priority. Throughout the supply chain, right up to the service station, Excellium fuel is monitored to verify its quality and conformity: procedures are in place to check for any potential fuel degradation (contamination by another substance, product, presence of water, oxidation, etc.). Regular quality checks are also carried out at service stations.

By choosing Excellium fuels, you are opting for a product of consistent quality, regardless of the type of fuel chosen, petrol or diesel.
