Ultra-STMSeries

The Ultra-STM hydroisomerised base oils are ideal

for blending high performance automotive &

industrial lubricants. They have superior low

temperature fluidity coupled with low volatilityand outstanding oxidation stability.

Ultra-STM4, 6 & 8 will enhance the performance

of low viscosity engine oils, premium ATFs, low

viscosity Automotive Gear oils, premium turbine

& compressor oils.

Features of the Ultra-STM Series.

SAE 5W30 and 5W40 engine oils, meetingthe latest ACEA, API, ILSAC and OEM

specifications, can be blended using Ultra-STM

4, 6 & 8 as the sole base stocks.

SAE 10W40engine oils can have their lowtemperature fluidity and oxidation stability

enhanced by the inclusion of up to 30 % of

Ultra-STM oils.

Low temperature fluidity. When Ultra-STMoils are used in low viscosity engine oil and

driveline lubricant formulations, the Cold

Crank Simulator and Brookfield dynamicviscosities are substantially improved.

Noack Volatility: The hydroisomerisationrefinery process of the Ultra-STM base oils

ensures that superior volatility performance is

established compared with conventionally

refined oils.
