At Repsol Lubricants we know that caring for the engine is a priority for those who trust in us, so we work every day to offer the best quality. We are pleased to announce that we have updated the formulas of two lubricants in the Leader range: Neo 0W-20 and Neo 5W-20

With these improvements, we optimize the performance of your car while adapting to the current needs of efficiency and protection, since the Neo products in the Leader range are characterized by always having the highest quality available from API and ILSAC. Below, we tell you everything you need to know about these new versions.

Leader Neo 0W-20: designed to bring out the best in your engine

Leader Neo 0W-20 is a synthetic lubricant designed for those looking for a perfect balance between performance and engine protection. Thanks to its formulation with 3E Technology (Excellent Engine Efficiency), this oil protects the engine against wear and deposits. In addition, its low viscosity helps reduce fuel consumption by up to 3.9% (according to the Sequence VIE ASTM D8114 test).

This product complies with API SQ and ILSAC GF-7A quality and is specially designed for gasoline and hybrid vehicles, including those models from Fiat, Lancia, Ssangyong, and Toyota that recommend the ILSAC GF-6A level. In addition, its compatibility with engines that use fuels with ethanol up to E85 makes it a versatile and reliable option.   

Leader Neo 5W-20: efficiency and protection in every kilometer

Leader Neo 5W-20 has also been reformulated to offer superior performance. This synthetic lubricant combines advanced protection with energy efficiency, achieving a reduction in fuel consumption of up to 2.6% (according to the Sequence VIE ASTM D8114 test), so you can enjoy longer and more efficient journeys without compromising your engine’s durability.

Like the Neo 0W-20, this product is recommended for gasoline or hybrid cars and meets API SP and ILSAC GF-7A standards, ensuring its quality and reliability. In this way, it protects the engine against the formation of sludge and deposits, keeping it clean and in optimal condition.
