Castrol reinvents the oil change with Nexcel

The revolutionary technology that makes oil changes quick, smart and simple

In 2015 Castrol launched Nexcel, a new revolutionary technology that marks one of the most significant oil change innovations in automotive history.

The Nexcel oil cell is an easy-to-change unit containing both engine oil and filter. It’s been designed to reduce tailpipe CO2 emissions(1), to improve vehicle servicing and to increase the recycling of used oil for road cars of the future.

Nexcel: What is it?

The Aston Martin Vulcan track-only supercar is the first vehicle to feature Nexcel technology.
Richard Parry-Jones, automotive industry leader and Chairman of the Nexcel Advisory Board said: “If you look back through the whole of Castrol’s history they’ve been innovators, using science to improve the performance of their lubricants and lead their industry. Nexcel represents one of its most significant innovations. It offers a solution to a problem that is increasing on the radar scope of manufacturers and when the Nexcel technology becomes standardised, people will wonder why we did it any other way.”

When engineered into the powertrains of the next generation of hybrid and internal combustion engined cars, the system will offer manufacturers and motorists three primary benefits in CO2 reduction, sustainability and servicing:

  • Nexcel has been designed to reduce tailpipe carbon dioxide (CO2) emissions by ensuring a precise oil-engine match and helping the oil to warm up more quickly.
  • The plug’n’play oil cell slots in and out under the bonnet, changing oil & filter in one quick, clean step taking about 90 seconds and allowing installers to offer more flexible and convenient service options to customers.
  • In western Europe, it is estimated that today up to 25% of used engine oil is not collected by licensed waste disposal operators.(2) The sealed Nexcel oil cell ensures that used oil is collected safely & can be recycled back into high quality engine oil products .
When the Nexcel technology becomes standardised, people will wonder why we did it any other way.

The Nexcel system has been tested on a range of engines from very small city cars to cutting-edge high-powered racing engines in the most extreme of conditions. It functioned smoothly even under severe braking of up to 1.8G, the equivalent of a vehicle travelling at 100km/h stopping dead in 1.6 seconds. Additionally, the system oil flow has been tested up to 600 litres a minute –10 to 20 times greater than seen in a conventional passenger car engine. A Nexcel oil cell and dock has been fitted in a trial hybrid vehicle to demonstrate the packaging potential in a 2018 Toyota Prius plug-in hybrid.
Testing of the latest Nexcel active engine oil management system across three different engine types demonstrated the system’s potential to reduce CO2 emissions by 2 g/km. The reduction is delivered by ensuring a precise oil-engine match, helping the oil to warm up more quickly and boosting the oil’s active components in-between oil changes.

2 g/ km is a useful contribution for the car manufacturers in helping them to achieve the EC’s proposed CO2 targets for cars post-2020. The saving adds up over a car’s lifetime, amounting to a total reduction equivalent to reducing a car’s weight by a third.
