Millers Oils CRX NT+ is a 75W90 fully synthetic gear oil designed for use in manual transmissions,...Millers Oils CRX NT+ is a 75W90 fully synthetic gear oil designed for use in manual transmissions, hypoid differentials and transfer boxes which require a GL-4 or GL-5 oil and are subjected to high loads. This makes it ideal for transmissions in competition or high performance road cars. CRX NT+ contains Nanodrive technology which provides a significant reduction in wear and friction compared to standard gear oils which reduces power loss and increases component protection. Exceptional cold flow properties for easier gear changes High film strength for maximum component protection Significantly reduces friction, temperature, wear and minimises power loss Ideal for Motorsport or high performance road cars Millers Oils CRX NT+ is recommended for use in modern transmissions where a synthetic oil with a GL-4 or GL-5 performance is specified. Ideal for use in manual transmissions with synchromesh or dog engagement including sequential gearboxes. It is also suitable for use in transfer boxes or hypoid differentials without plate type LSD's. What is NanoDrive Technology? NanoDrive technology uses spherical nanoparticle structures within the oil. Configured in a similar sort of composition to an onion, with 'skins', the Nano particles retain their protective properties under load, even under extreme pressure and will only 'shed' a layer without overall particle failure and loss of viscosity. The nanoparticles 'fill' any rough metallic surfaces to create a super smooth surface which ensures minimum wear on components and minimum power loss. Specifications: API GL-4, GL-5, MT-1, MIL-PRF-2105E Recommendations: ZF TE-ML-02B / 05B / 07A / 12B / 16F / 17B / 19C / 21B

FAQs
What is Nanodrive Technology?
Nanodrive technology uses spherical nanoparticles that create a super-smooth surface on metal components, dramatically reducing friction and wear, even under extreme pressure. These particles provide a protective layer that minimizes power loss and extends component life.
Can I use this oil in my limited-slip differential?
Millers Oils CRX NT+ Nanodrive 75W90 is suitable for hypoid differentials without plate-type LSDs. It is not recommended for differentials that use plate-type LSDs.
Is this oil suitable for daily driving?
Yes, it is suitable for high-performance road cars for daily driving, offering enhanced protection and smoother operation. However, its primary design is for high-load and performance applications.
What is the difference between GL-4 and GL-5 oil?
GL-4 oils are typically used in manual transmissions with yellow metal components (like brass synchros), while GL-5 oils offer higher extreme pressure protection for hypoid differentials. CRX NT+ meets both specifications, making it versatile.
How often should I change this gear oil?
For competition or severe use, more frequent changes are advised. For regular road use, adhere to your vehicle manufacturer's recommended service intervals for gear oil replacement.
Will this oil improve my car's performance?
Yes, by significantly reducing friction and power loss, it can lead to a marginal improvement in drivetrain efficiency and power delivery. Its main benefit is enhanced component protection and smoother operation.
Where can I buy Millers Oils CRX NT+?
This product is available through authorized Millers Oils distributors and specialist automotive parts retailers.
Troubleshooting
Difficulty engaging gears, especially when cold
While CRX NT+ has excellent cold flow, ensure the correct oil level. If the problem persists, check for internal transmission wear or synchro issues.
Increased noise from transmission or differential
Check the fluid level and for any signs of leaks. Excessive noise could indicate internal wear; inspect components if possible or consult a specialist.
Oil appears milky or contaminated
This can indicate water ingress. Drain and refill the unit immediately and investigate the source of contamination (e.g., seals).
Gear changes feel notchy or rough
Ensure the oil is fully circulated by driving for a few minutes. If the issue persists, it might indicate wear on synchromesh rings or other internal components.
Pros and Cons

Setup, Compatibility & Care
Setup:
Ensure the vehicle's transmission, differential, or transfer box is drained of old fluid.
Verify that the correct fill and drain plugs are accessible and clean.
Using a suitable fluid pump, carefully fill the component with Millers Oils CRX NT+ Nanodrive 75W90 until it reaches the manufacturer-specified level (usually up to the bottom of the fill hole).
Replace and tighten the fill and drain plugs securely.
Compatibility:
Recommended For: Manual transmissions, hypoid differentials, and transfer boxes specifying API GL-4 or GL-5 performance. Also suitable for ZF TE-ML-02B / 05B / 07A / 12B / 16F / 17B / 19C / 21B.
Not Suitable For: Differentials with plate-type Limited Slip Differentials (LSDs).
