The Group IV and Group V base oil charts shown in our Global Lube Base Oil Specification Quick Reference Center, listed in the right hand column of the OEM/Lube News, have been revised. Several base oil manufacturers/ refineries have been added, as well as updates to the products which the listed companies produce and market.
These modifications include the following:
Group IV base oils - addition of (Tafneft, for example) and deletion of (for example, Idemitsu Kosan, who has, at least for now, exited the PAO business) companies, as well as the addition (ChevronPhillips Chemical Synfluid mPAO, for example) and deletion (ExxonMobil Chemical SpectraSyn Ultra, for example) of many base oil cuts and modification of some of the viscosities. To view the chart, click here or click the Group IV link under Global Lube Base Oil Specification Quick Reference Center in the right hand column of the OEM/Lube News.
Group V base oils - addition of (Clariant esters and PAGs and Calumet POEs, for example), as well as significant additions and some deletions of many base oil cuts and modification in some of the viscosities. To view the chart, click here or click the Group V link under Global Lube Base Oil Specification Quick Reference Center in the right hand column of the OEM/Lube News.
Please note that the Group V listing includes all naphthenic base oils together at the end of the Group V synthetic basestock listing.
Also, by clicking on the logo of certain base oil refiners (those where noted underneath the data in red letters) within these charts will take you directly to their base oil web page or to their complete base oil data sheet. For example, please click on the Inolex logo in the Group V chart or the ExxonMobil Chemical logo in the Group IV and the Group V chart to view how this feature works.
We would like to take the opportunity to thank the many oil companies that contributed to this study by providing detailed data to us. If any modifications to these charts are necessary, please advise.
