Shell Gadinia AL 40 is a premium-quality, SAE 40 marine diesel engine lubricant specifically engineered for highly rated, medium-speed trunk piston engines operating on distillate fuels (ISO 8217 DMX, DMA, DMZ). Delivered in a robust 209-liter industrial drum, this advanced formula is optimized for high-stress marine propulsion and auxiliary power systems where keeping engine components pristine, controlling oil consumption, and avoiding liner lacquering are critical priorities. With its 15 TBN (Total Base Number) formulation, Shell Gadinia AL 40 provides strong acid-neutralization properties, effectively insulating engine internals from corrosive wear caused by fuel sulfur combustion byproducts. The higher SAE 40 viscosity grade ensures an incredibly stable and thick oil film under extreme heat and heavy loads, providing enhanced wear protection for pistons, liners, and bearings. Its excellent thermal and oxidation resistance prevents varnish, sludge, and carbon buildup in the critical piston ring belt. The 209-liter bulk volume is perfect for commercial shipping fleets, passenger ferries, power generation plants, and offshore rigs, offering long service life, extended drain intervals, and reliable machinery protection.
