Millers Advanced Oils and Fuel Treatment

With over 135 years of experience creating advanced lubricants, Millers Oils Ltd can be trusted to keep your engine performing at its best, whatever you drive. Their innovative formulations don’t just lubricate but they also actively reduce friction, protect against wear, and deliver measurable power improvements.

Modern engines face increasing demands with higher temperatures, pressures, and tighter tolerances. Millers’ advanced additive technology creates a protective layer using specialised nanoparticles that adhere to metal surfaces, preventing destructive metal-to-metal contact even under extreme conditions.

This technology combines with triple ester chemistry to achieve remarkable results. Laboratory testing shows friction reductions of over 50% compared to conventional oils, with corresponding improvements in power output, fuel economy, and component life.

Millers engine oil falls into three main ranges: CFS (Competition Fully Synthetic engine oil) for maximum performance applications, EE Performance for high-performance road use, and Classic for vintage vehicles. At Cox Motor Parts, we stock the complete range and can help you find the perfect Millers oil for your needs.

At Cox Motor Parts, we’ve spent years supplying quality engine oils for all types of vehicles. Our carefully selected Millers range includes premium synthetic formulations designed to keep your engine running smoothly, lasting longer, and performing at its peak.

Millers Car Oil FAQs

Millers Oils is a British independent oil blender founded in 1887 and based in Brighouse, Yorkshire. The company has been providing high-quality lubricants and advanced oil technology for over 100 years, making them one of the most experienced oil manufacturers in the world.
Millers and Castrol produce excellent oils, but have different needs and applications. The choice depends on your requirements, driving style, and what you want from your engine oil. Millers oils excel in high-performance applications where maximum power gains and protection are priorities. Castrol offers a broader range that covers everyday driving needs with excellent reliability and wide availability. Both brands provide excellent protection for standard driving, but for modified engines, track use, or where maximum performance is essential, Millers' specialised formulations often provide advantages that justify the investment.
The right Millers oil depends on your vehicle's specifications and how you use it. Check your owner's manual for the required viscosity grade (like 5W-30) and performance standards (like ACEA A3/B4). For everyday driving in modern cars, the EE Performance range offers excellent protection with advanced low-friction technology while meeting manufacturer specifications. The CFS range provides maximum power gains and protection if you have a high-performance or modified vehicle or do track days in motorsport. Our technical team can help identify the perfect Millers oil for your specific vehicle. For expert advice,just contact us with your registration number or vehicle details
