Viscosity results of used lubricating oil samples are compared to the original equipment manufacturer’s (OEM’s) requirements whenever possible. If this is not feasible, the generally accepted limit for viscosity change is ±15% of the fresh oil value at 40°C. For large diesel engines, an increase of the engine oil’s kinematic viscosity ...
It shows the ISO viscosity grade, AGMA grade, SAE crankcase grade and SAE gear grade. The viscosities of these are shown as the kinematic viscosity in centiStokes at 40 and 100°C, and the Saybolt viscosity in Saybolt universal seconds at 100 and. 210°F.
High-performance engine oil for highly rated, high-speed diesel engines that meet the latest API and ACEA specifications Suitable for engines burning distillate fuels with a sulphur content of up to 1.0 %wt.
High quality, multifunctional diesel engine lubricants designed for the most severe service main propulsion and auxiliary marine trunk piston engines burning distillate, hybrid and biofuels with a sulphur content up to 1%.
Viscosity index (VI) The viscosity of lubricating oil changes with temperature and the rate of change depends on the composition of the oil. Naphthenic base oils change more than paraffinic base oils. Certain synthetic lubricants change much less than paraffinic oils.
Mobil Delvac MX oil provides reliable performance across engine types. It is recommended for use in modern marine high-speed diesel engines, including demanding, low-emission designs.
