Shell Industrial Product Identification
Through their industrial product portfolio, Shell offer a range of lubrication solutions for a variety of business sectors. Understanding the differences between these products is key in determining which product is best suited to a particular application, and the below information is designed to provide an initial framework for product selection.
Tier – Grade of Oil
The grade of oil is identified by an ‘S’ followed by a number. The higher the number, the more efficient the protection provided by the lubricant.
So for example, Shell Omala S4 provides more efficient protection than Shell Omala S2.
Suffix Letter – Application Indicator
Following the tier, there is an additional letter, the meaning of which differs depending on the product family. These letters indicate unique characteristics around that sub set of lubricants and can also identify the specific applications they suit:
ISO Grade – Viscosity
The number that follows the suffix letter indicates the viscosity. This is the thinness or thickness of the material, and is measured using the ISO Viscosity Grade system.
NLGI Grade – Shell Gadus
As the brand name for the grease family, the Shell Gadus range has an additional number to identify the NLGI. This is consistency of the grease, and ranges from 000 (fluid) to 6 (block). More information on NLGI can be found in our Greases Explained article here.
