Lubricating oils, petroleum, C20-50, hydrotreated neutral oil-based, high-viscosity

Quote:

---

A complex combination of hydrocarbons obtained by treating light vacuum gas oil, heavy vacuum gas oil, and solvent deasphalted residual oil with hydrogen in the presence of a catalyst in a two stage process with dewaxing being carried out between the two stages. It consists predominantly of hydrocarbons having carbon numbers predominantly in the range of C20 through C50 and produces a finished oil having a viscosity of approximately 112cSt at 40.degree.C (104.degree.F). It contains a relatively large proportion of saturated hydrocarbons.

Was wondering if this is quality oil for general lubrication, and what group this might fall under. It is in a product that I use, and the description is different than most. Any info would be appreciated.

sounds like Chevron RLPO 600 Nuetral oil a GPII.

Thanks yet again Bruce. The oil in question has a 40C cst of 47.3 and a 100C of 7.0. That is final product with esters and additives added.

The Chevron 220R (GrpII) is close to this spec. Is there a major difference between the 600R and 220R besides viscosity? (Refining, content, etc.)

Sorry, one more thing. What is "vacuum gas oil"? I've never heard that mentioned before.

vaccuum gas oil comes from vaccum distilling the crude in the early/first process of making fuel or lube.
Finda first seperation of useful products from crude simple distilation.
