Repsol updates the Leader Neo 5W-30,10W-30, and 10W-40 formulas

After the improvements made in June to Leader Neo 0W-20 and 5W-20oils, at Repsol Lubricants, we continue to work on the evolution of our range of oils for gasoline and hybrid passenger vehicles. We are happy to announce that Leader Neo 5W-30 ,10W-30, and 10W-40 have raised their level to API SQ quality. In addition, in the cases of 5W-30 and 10W-30, they have incorporated the new ILSAC GF-7A specification.

API SQ, a quality evolution designed for the most modern engines, was incorporated into the API specification update for gasoline engine oils in March 2025, representing a step up from API SP. This new category offers improved energy efficiency, greater control over low-speed pre-ignition (LSPI) in direct-injection turbo engines, optimized component cleaning, and increased oil durability during use.

In parallel, ILSAC GF-7A follows GF6A and introduces significant improvements in engine protection and fuel efficiency, as well as contributing to reducing deposit formation. This new quality is incorporated into Leader Neo 5W-30 and 10W-30.

This brings the whole family in line with the latest regulations for gasoline and hybrid engines, with a focus on efficiency and protection.
