Shell Rimula R4 X 15W-40 is distinguished by a unique formulation that has been tested in real operating conditions, guaranteeing the efficiency and durability of engines. This oil provides effective protection against corrosion thanks to significantly improved neutralization of acidic substances formed during fuel combustion. High thermal stability of the oil provides excellent protection against deposits on the pistons, and the use of high quality dispersants results in effective protection against the formation of sludge and deposits in the engine. The combination of active anti-wear additives and elements ensuring high engine cleanliness minimizes wear, extending its durability, maintaining power and efficiency, and also reducing maintenance costs.
