Technical issues in base oil manufacture

SAE 0W-20 and 0W-30 full Group III oils tend to be borderline or

needed PAO partially on both low temperature viscometrics and

volatility

Base oil properties controlled through feedstock selection and

manufacturing process

Refiners continue to search for innovative ways to maximize

iso-paraffins and small-ring paraffins

- Increasing hydrocracker severity

- Waxy feeds

Gulf(now Chevron) introduced lube oil hydro-treating technology (Idemitsu Kosan, Chiba, 1965)

Shell introduced severe hydro-treating for HVI base oil (1972), and VHVI base oil from slack wax (1978)

BP was the first VHVI base oil manufacturer from fuels hydrocracker residues (1984)

Chevron designed lube oil complex for HVI base oils (1983-1984), Iso-dewaxing (1991) and VHVI base oils (1996)

SK Energy integrated fuels hydrocracker and lube catalytic dewaxing (1995)

Summary

New YUBASE has superior properties in low temperature fluidity

and volatility

Higher VI Group III base stock, New YUBASE

SAE 0W-20 and 0W-30 PCMO can be formulated by New YUBASE

without PAO treatment

There is no advisable effect on low temperature low shear property and seal compatibility

Need further study to confirm fuel economy in 0W-XX, 5W-XX

PCMO formulations
