Chevron UCBOs deliver synthetic performance and are ideal blending
stocks for achieving the low-volatility standards required for many
crankcase engine oil applications. Chevron UCBOs are the logical choice for:
- Next-generation, premium engine oils
- Extended-drain transmission and gear fluids
- Severe-duty hydraulic and power transfer fluids
- Long-life turbine and industrial oils
Higher VI:
UCBOs have very high viscosity indices ranging from 120 to 140 VI compared to
conventional neutral base oils at about 95 VI.
Higher Purity:
All Chevron base oils are produced by all-hydroprocessing which lowers the level
of undesirable components such as aromatics, sulfur and nitrogen, resulting in a
chemically pure, clear base oil.

Exceptional Oxidation Stability:
The higher purity and VI levels of Chevron UCBOs make them exceptionally resistant
to oxidation. In tests, Chevron UCBOs produce oxidation stability approaching that
of polyalphaolefin synthetics, making them ideal for lubricants where longer life
is required, even under the highest operating temperatures.

More Stable Viscosity:
Chevron UCBOs have very high VIs, providing more stable viscosity at extreme
temperatures. So lubricants thicken less at cold temperatures and thin less
at high temperatures - providing better wear protection and longer
equipment life.

Lower Volatility:
The higher VIs of Chevron UCBOs also help make them much less volatile, or
less prone to evaporation.
- Engine oils that provide lower oil consumption
- Industrial oils and power transmission fluids that have less fluid loss
- Lubricants that show less thickening.
