GReddy F3 RE-SPEC 10W40 – Mazda RX-7 & RX-8 Rotary Engine Oil

The GReddy F3 RE-SPEC 10W40 is a high-performance engine oil specially developed for Mazda rotary engines. Designed to meet the demands of RE Turbo and RE NA engines, it ensures optimal protection for rotors, seals, and internal components while providing the characteristic responsiveness of rotary engines.

Thanks to its advanced synthetic formulation, GReddy Synthetic Composite Formulation, this oil offers excellent thermal stability, enhanced lubrication, and high resistance to stresses encountered during sporty use and high RPMs.

Its high-performance, low-ash additives limit the formation of deposits and sludge on the rotors and crankcase walls, while reducing wear on the seals. Its optimized viscosity also promotes rapid acceleration and improved engine response.

Specifically developed for rotary engines, this oil is ideal for sporty road use, lightly modified vehicles, and more demanding applications.
