Penrite Full Synthetic 10W-40 is a premium nonfriction modified 10W-40 engine oil featuring Penrite's Full Zinc Technology. Penrites Full Zinc additive package creates a sacrificial layer on critical engine components to protect them from metal to metal contact and cold start wear. With a combination of a low shear rate viscosity modifier this oil provides additional protection against wear, corrosion, oil oxidation, piston deposits and sludge formation under higher ambient temperatures and severe operating conditions. Suitable for use in modern multi-cam and multi-valve petrol, LPG, E10, and diesel vehicles without diesel particulate filters (DPF). Can also be used in four stroke motorcycles with wet clutch assemblies and E85 fuelled vehicles providing more frequent oil drain intervals are adhered to.
