Shell Tellus
The Shell Tellus range of hydraulic fluids has been developed to enable equipment operators to select the oil that can help deliver optimum value to their operations through enhanced wear protection, long oil life and high system efficiency.

Old and New Names
When ISO standardisation was introduced for measuring oil viscosities, Shell renamed all of their oils from their old pre-ISO names to new ISO-VG names. Many old machine manuals specify the old pre-ISO grade, and you need to understand how they were renamed to get the right oil. Don't assume that Shell Tellus 33 (Pre ISO) is "close enough" to Shell Tellus 32 (ISO), as the two numbers mean different things.
The table below should help you understand how they were renamed.
