CAS number reference

[GregH]

Where do you guys get the info on the CAS numbers on the MSDS on oils. After finding that Valv uses group 1 in their HM oils, makes me want to be a little more observant on what I purchase.
THanks in advance

Maxlife latest MSDS does not show Group I anymore.

Search the CAS number on this site and on Molakule. If he defines it, you can be pretty sure it's right.

Thanks guys for the prompt info. I think some of you sit and wait for questions from dummies such as myself.
Thank again

How would you go about determing what group base stock this oil is?

From the description "hydrotreated heavy paraffinic" means it is a group II or III or a mixture of both. It depends on the viscosity index.

Bruce 381 (a Lubrication Engineer) has stated that just about anything that is solvent refined is Grp I. There may be a few rare exceptions to this.
