ULTRAgrade® 15 and 19 oils result from a new process. Most manufacturers use a solvent refining process, whereas these oils are produced by a unique hydrotreating process. This process eliminates nitrogen, sulphur and oxygen and the aromatic hydrocarbons, leaving a clear base stock essentially free of impurities.

• When combined with additives, the ULTRAgrade® gives improved vacuum performance, thermal and oxidation stability and rust inhibition
• The anti-oxidants included in the oil enable the pump to withstand high operating temperatures without oil degradation, so extending intervals between oil changes
• The properties of the oil allow them to be used in a wide range of applications
