Total Lubricants launches next-generation oils
Total Lubricants has announced the arrival of its latest generation of heavy-duty engine oils, branded Rubia Optima.
The oils, whose specifications have been driven by legislation and OEM requirements, are said to deliver improvements in engine protection and fuel economy, while also lowering CO2 emissions.
“With regulators setting stricter greenhouse gas emission limits, engine manufacturers need to make diesel engines cleaner and more fuel-efficient than ever before,” said Total Lubricants.
“In turn, lubricant manufacturers need to produce new oils for these new engines. OEMs are also looking for improvements in oil oxidation control, aeration control and shear stability.”
The company continued: “Both specifications [API CK-4 and FA-4] deliver superior performance over current oils. The former will protect new and older engine models, while the latter is designed to provide optimised fuel economy for 2017 engines and beyond.
“CK-4 oils replace CJ-4 oils with the same viscosity grades and oil types (mineral/synthetic) and are backwards compatible down to CF-4. FA-4 oils are lower in viscosity grades to help maximise fuel economy without compromising durability for next generation engines. However they are limited in backwards compatibility.”
The new categories of oils are said to be the result of years of collaborative effort between the oil and additive industries and diesel engine manufacturers, in an effort to make diesel engines cleaner and more fuel-efficient.
“The new Total Rubia Optima oils bring huge benefits to customers, not just through reducing emissions and improving fuel economy, but also by providing better protection against wear and a greater resistance to breakdown,” said Total.
“The robust new oils provide greater shear stability when coping with higher loads and the risk of oil pressure loss is diminished. Bubbles in the oil can reduce the ability to cool and protect an engine so the new changes now provide improved aeration control.”
The new oils also provide improved oxidation stability, the firm adds; oxidation degrades the oil, causing harmful sludge and viscosity increase, but the new formulas enhance resistance to oxidation.
“With improved aeration and oxidation stability, the new oils are designed to provide greater protection and efficiency for vehicles working in the harshest of environments, and extreme temperatures.
“These product benefits all combine to bring significant benefits to the customer, ranging from reduced emissions, cost savings on fuel, extended oil drain intervals and lower maintenance costs.”
