Ultra engine oils – top class from Rolf
The Ultra Series
Rolf Ultra – an advanced fully synthetic oils
Rolf Lubricants GmbH advanced developments have manifested in the Ultra lubricant line. These oils are formulated on the basis of combination of high-quality GTL (gas-to-liquid) and PAO (polyalphaolefins) fully synthetic base stocks remarkable for their excellent low- and high-temperature characteristics.

Excellent Cold Resistance
In particular, the Rolf Ultra products retain pumpability even at extremely low temperatures. Depending on the formulation, the pour point of an oil based on GTL + PAO can be up to -65°С. Such excellent results have been demonstrated in the tests with the cold-cranking simulator (CCS) and the mini-rotary viscometer. This means that these oils ensure a reliable start of the internal combustion engine at temperatures below -30°С due to a quick supply of the lubricant to the friction elements and their protection against wear.

Heat Protection and Low Volatility
Rolf Ultra oils demonstrate low volatility (NOACK) and excellent oxidation resistance at high temperatures and pressures (PDSC – Pressure Differentiation Scanning Calorimetry and MB Oxidation Test). This ensures protection of modern thermally-loaded engines with high output per litre ratings, as well as other power trains whose cooling systems are unable for different reasons to dissipate the excessive heat.

Rolf Ultra Oils = Long Life
The advantage of GTL + PAO base oil combination lies in the fact that it unties the best features of each base oil: low temperature parameters of PAO and the ability to dissolve additives of the GTL . As a result we get an almost perfect base oil with unique low-temperature characteristics and very high thermo-oxidative stability.
This provides the properties of the engine oil to be retained throughout all service interval and even much longer. This is why we can confidently label them as “The Long Life Engine Oils”.

Compliance with standards and exceeding them
According to the complete trials carried out at the independent research center ISP Salzbergen GmbH & Co. KG (Salzbergen, Germany), which conducts lubricants testing for the leading global car manufacturers, Rolf Ultra oils fully comply with the requirements of European and international quality standards and even significantly exceed them for in a number of indicators. In particular, our oils are much ahead of the standards in tests for oxidative stability, low-temperature pumping viscosity and resistance to oxidation under the oxigen pressure.
