Product Information
Full details
This Millers Oils COR (Competition Oval Racing) 20W50 engine oil is designed for short circuit racing engines and large capacity V8s, offering maximum power and wear protection through its semi-synthetic formula with Nanodrive technology. While providing a significant 15% reduction in friction over previous versions, users should ensure their engine specifications are compatible with a 20W50 oil and high ZDDP content.

FAQs
What is Nanodrive technology?
Nanodrive technology is a proprietary lubrication system developed by Millers Oils that uses advanced additives to significantly reduce friction within the engine, leading to increased power and reduced wear.
Is this oil suitable for everyday road cars?
This oil is specifically designed for racing applications. While it may work in some older, high-performance road engines, it is generally not recommended for modern road vehicles, especially those with catalytic converters, due to its high ZDDP content.
What does 20W50 mean?
20W50 refers to the oil's viscosity. '20W' indicates its flow characteristics at cold temperatures (Winter), and '50' indicates its viscosity at operating temperature. This is a relatively thick oil suitable for high-temperature and high-load conditions.
Why is high ZDDP important for classic engines?
Classic engines often use flat tappet camshafts that rely on the anti-wear properties of ZDDP (Zinc Dialkyldithiophosphate) for protection. Modern oils often have reduced ZDDP to protect catalytic converters, which can lead to premature wear in older engines.
How often should I change this oil in a racing application?
For racing, oil condition degrades much faster. It is recommended to change the oil more frequently than in a road car, often after every few race days or as per your specific racing team's or engine builder's recommendation.
Can I mix this oil with other brands or types of oil?
It is generally not recommended to mix different brands or types of engine oil, as it can compromise the performance and protective properties of the formulation. If changing oil types, it is best to flush the system.
Troubleshooting
Oil pressure is lower than expected.
Verify the oil level is correct. Check for any leaks in the oil system. Ensure the oil viscosity is appropriate for the operating temperature; a 20W50 may be too thin if severely overheated.
Engine sounds noisy or shows signs of wear.
Confirm the oil is not past its service life. Check if the oil is suitable for the engine type (especially if it's a classic engine requiring high ZDDP). Ensure the oil filter is not blocked and is functioning correctly.
Oil appears excessively dark or foamy.
Dark oil can indicate normal operation under heavy load, but if extremely dark or sludgy, it may be time for an oil change. Foaming can indicate air entering the system or issues with the oil's anti-foaming agents; check the oil level and look for potential aeration sources.
Pros and Cons
Pros
- Significantly reduces engine friction for improved power.
- Provides superior wear protection for critical engine components.
- Specifically formulated for high-performance racing applications.
- Enhanced protection for engines with flat tappet camshafts due to high ZDDP content.
- Durable semi-synthetic base for extended oil life under stress.
Cons
- May not be suitable for modern engines with catalytic converters due to high ZDDP content.
- Requires verification of compatibility with specific engine requirements.
- The 20W50 viscosity may be too thick for some standard road engines, especially in colder climates.
- Performance benefits are most pronounced in demanding racing conditions.
Setup, Compatibility & Care
Compatibility:
This oil is recommended for short circuit racing engines, large capacity V8 engines, and classic engines such as Ford Pinto and X-Flow. It is crucial to verify that your specific engine's design and performance requirements are compatible with a 20W50 viscosity and a high ZDDP content. Modern engines with sensitive emission control systems (like catalytic converters) may not be suitable due to the high ZDDP levels, which can cause catalyst poisoning. Always consult your vehicle's owner manual or a qualified mechanic.
Oil Changes:
Follow the manufacturer's recommended oil change intervals for your specific application. For racing use, more frequent changes may be necessary depending on the severity of the operating conditions. Ensure you use the correct quantity of oil as specified for your engine.
Storage:
Store the oil in its original container in a cool, dry place, away from direct sunlight and extreme temperatures. Keep the container tightly sealed to prevent contamination.
