Look up the patent. It is claimed to be a patented Titanium additive. I doubt Blackstone knows anything about it.

BP Magazine meets the Castrol team behind a new lubricant molecule that responds to the demands of the latest vehicle engines - where oils are under more pressure than ever before

What are the factors that will most influence the design and manufacture of tomorrow’s cars? It doesn’t take a crystal ball to predict that drivers in the middle of the 21st century will likely be behind the wheels of cleaner, faster and cheaper vehicles. Certainly, the automobile industry is already well on the road to pursuing many of these goals, often driven by government legislation and consumer demands.
Today’s technology has allowed car manufacturers to produce smaller, yet more powerful and efficient engines. Their aim is to deliver increased fuel economy, reduced emissions and high performance. But the focus on down-sizing, turbo-charging and advanced designs have meant engine pressures have almost doubled over the last 30 years.
With the highest pressures found in the camshaft – the area of the engine where parts called lobes meet the valves and push them open – these parts need protection when they come into contact. That comes from a very thin layer of oil.
Today’s engine oils operate under higher temperatures and greater stress than ever before. To address these challenges, BP’s chemists and engineers in its lubricants business have generated a new molecule to provide extra strength in the oil films of its Castrol EDGE product range.
The right chemistry
This technology journey began several years ago in a laboratory in New Jersey, US. “We’re always looking at different chemistries or components that may allow us to enhance performance attributes of our lubricants,” says Mario Esposito, Castrol’s team leader for polymer development and passenger car oils, at the Wayne Technology Center.
“Our research initiatives are essential,” he adds. “We formulate our lubricants around individual, proprietary ingredients, creating a ‘hand crafted’ differentiated offer, and with Castrol EDGE, we aimed to develop a performance additive that made the lubricant stronger.”
Castrol’s team of chemists built that molecule from scratch, as polymer research manager, Richard Sauer explains: “We were assessing a range of transition elements, trying to identify which one would bring value to a finished oil. We needed to assess the advantages of each element, looking at factors such as engine deposits and wear control.
“We looked at how a metal may be incorporated onto a polymer to complete a finished engine oil with the desired performance attributes. Generally speaking, functional polymers bring extra performance characteristics to a completed formula. As well as identifying the chemistry, we also had to work on putting together a viable commercial process.”
"To synthesize a molecule and make it a commercial reality takes a huge global effort over many years."

Through their analysis, the chemists pinpointed a titanium molecule that displayed the sought-after characteristics: the additive changes the freezing pressure of the lubricant under extreme pressure and it actively thickens and reinforces the oil film. In an engine, that means it offers greater protection at high-pressure contact points, giving the oil the ability to keep metal surfaces apart more effectively with a cushioning effect.
The laboratory results needed rigorous testing in the real world to make sure that the claims could be substantiated. Castrol’s team in Pangbourne, UK, led this phase of development to formulate the oil and test the effects of titanium to reduce friction and resist film breakdown.
“The next stage involved blending the new formulation with our laboratory technicians to optimize the viscosity of the product and later run the prototype formulations through engine tests,” says Simon Gurney, automotive engineer and senior development technologist. “We test parameters such as impact on engine wear, sludge build-up and piston cleanliness. Some tests can take several weeks to run – the longest was a 900-hour engine test. These are extreme by nature, creating conditions that will never be seen in a car on the road.”
Tests also followed with original equipment manufacturers (OEMs) and other research facilities. “We worked with a Scottish university to independently test the additive under very high pressure,” says senior technologist, Gareth Dowd. “This confirmed that adding the titanium improved fluid strength by changing its physical behaviour.”
