Gulf Roadster 5W-40 100% Tri Synthetic Engine Oil for 3.7L Gasoline-Powered 4-Wheel Vehicles

Exclusively for the Mazda Roadster A special ester has been added to the existing PAO + Ester formula to create a triple synthetic formula. This special ester not only protects the engine during dry starts, but also improves adhesion to metal surfaces and significantly reduces friction. Even as the oil temperature rises in the Roadster's engine compartment, which is prone to heat buildup and high temperatures, a uniform, strong oil film is maintained on the metal surface. A 5W-40 viscosity grade is used for the engine's highly engineered design and relatively narrow oil lines (oil passages). Thicker oils may not penetrate the HLA (lash adjuster) during cold starts in the B6-ZE, causing a rattling noise. The low viscosity of the Gulf Roadster oil reduces noise and extends engine life. The Gulf Roadster oil is formulated and adjusted for a high high-temperature, high-shear viscosity (HTHS). This means a stronger oil film at high temperatures and less wear on engine parts. It's not enough to simply use a low-viscosity oil; Gulf's technical expertise, backed by a long history, has made it possible to create a special oil that suppresses oil degradation while bringing out the best in your Roadster's engine performance and extending its lifespan. This oil is ideal for everything from stock to fine-tuning, and for driving in urban areas or on the circuit. Founded in Texas, USA in 1901, Gulf is a global oil brand with over 100 years of history. It develops high-quality, high-performance engine oils, delivering race-proven performance for everyday use. This new, even higher-performance oil has been released specifically for the Mazda Roadster, adding a special ester to the existing PAO + Ester formula to create a triple synthetic blend. This special ester not only protects the engine during dry starts, but also improves adhesion to metal and significantly reduces friction.
