Millers Oils CFS 10w40 Fully Synthetic Engine Oil

This is a competition, fully synthetic oil suitable for petrol and diesel engines. CFS 10w40 has been formulated with 100% synthetic base fluids, as well as a mixture of three esters which combine the latest additive technology for peak performance.

CFS 10w40 is particularly suitable for smaller capacity rally and race engines, but also turbocharged engines used on fast road and track days. It can be used as a high-performance alternative to a conventional oil, where the specification recommended by the manufacturer is 10w40.

This Millers engine oil utilises their original NanoDrive low friction technology, which boosts overall power. Load carrying capacity is also increased, particularly in comparison to that achieved with a mineral oil. It also contains a high film strength for ultimate protection.

Friction is reduced by up to 26%, while wear is decreased when compared to a standard engine oil. At start up, CFS 10w40 has outstanding cold flow properties and excellent oxidation resistance and thermal stability.

Using both polyalphaolefins (PAO) and ester synthetics, which have been specially selected to minimise polymer content, the lubricant film provided is more resistant to ‘shear’ and viscosity loss, especially in highly stressed areas. The ester blend also provides improved lubricity and reduced friction, enhancing the oil’s performance.

Millers Oils
Established in 1887, Millers Oils are a leading independent blender of oil and fuel additives. They have a wide range of different transmission and engine oils, as well as fuel treatments. Each is formulated to deliver outstanding performance and increased engine longevity.

We've tried to keep all other shipping costs as low as we can.

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).

  • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
