Advancing low carbon can involve finding new and innovative approaches to long-established methods. For example, Castrol has developed a way to transform the manner in which engine oil is changed – not only making the process simpler and quicker but also helping to reduce tailpipe carbon dioxide (CO2) emissions.


The Nexcel oil cell is an easy-to-change unit containing both engine oil and filter. The 'plug-and-play' oil cell slots in and out under the bonnet, meaning that oil and filter are changed in one quick, clean step that takes around 90 seconds to complete.


Nexcel reduces tailpipe CO2 emissions through a combination of thermal management – faster engine warm-up – and new bespoke oil formulations. We have tested the latest Nexcel active engine oil management system across three different engine types and demonstrated that the system has the potential to reduce CO2 emissions by 2 g/km. The sealed oil cell also means that used oil is collected safely and can be re-refined into high quality engine oil. The cell itself is then re-useable.


The new technology is currently standard fit on the limited edition Aston Martin Vulcan and other Aston Martin race cars. BP is working with a number of global car manufacturers to introduce the technology into more engines, with first road car applications intended soon after 2020.
