This heavy-duty 75W140 fully synthetic gear oil from Millers Oils, the CRX LS NT+ Nanodrive, is designed for competition and high-performance manual transmissions and axles, particularly those with plate-type limited-slip differentials (LSDs) requiring GL-4 or GL-5 oil. Its key benefit is the inclusion of Nanodrive technology, which significantly reduces wear and friction, leading to lower power loss and enhanced component protection. A potential consideration is its specialized nature, making it most suitable for performance applications rather than standard road vehicles.

Nanodrive technology uses microscopic spherical nanoparticles that fill imperfections on metal surfaces. This creates an ultra-smooth layer, significantly reducing friction and wear, even under extreme pressure, without compromising the oil's overall viscosity.
While it meets GL-4 and GL-5 specifications, CRX LS NT+ is optimized for high-performance and competition use. For standard road cars without LSDs or high-power demands, a less specialized gear oil might be more appropriate and cost-effective.
GL-4 oils are generally suitable for manual transmissions with synchromesh, while GL-5 oils are typically used for differentials, especially hypoid differentials, and offer higher extreme pressure protection. CRX LS NT+ covers both specifications, making it versatile for gearboxes and LSD-equipped axles.
For competition use, it's recommended to change it after every event. For high-performance road use, a guideline is every 20,000-30,000 miles, but always refer to your vehicle's specific service recommendations.
Yes, the Nanodrive technology significantly reduces friction and wear on internal components, extending the lifespan of your gearbox and differential, especially under demanding conditions.
Yes, the CRX LS NT+ includes specific friction modifiers designed for optimal performance in plate-type limited-slip differentials, promoting smooth lock-up and minimizing chatter.
Ensure the correct oil viscosity (75W140) and specification (GL-4/GL-5 with LSD modifiers) is being used. The exceptional cold flow properties of CRX LS NT+ should improve this, but check for any mechanical issues within the gearbox.
Verify that the CRX LS NT+ is being used, as it contains specific friction modifiers for plate-type LSDs. Ensure the correct quantity of oil has been added and that the LSD itself is in good working order.
While CRX LS NT+ reduces wear, persistent noise may indicate existing mechanical damage. Check for low oil levels or other underlying issues. Nanodrive technology helps protect components, but cannot repair existing damage.
Ensure the drain and fill plugs are tightened to the correct torque specifications. Check that the sealing washers are in place and in good condition. Replace if damaged.
Compatibility:
This oil is recommended for use in modern transmissions and axles where a synthetic oil with a GL-4 or GL-5 performance is specified. It is ideal for use in LSD-equipped axles and transaxles, as well as manual transmissions with synchromesh or dog engagement, including sequential gearboxes. Always consult your vehicle's owner's manual or a qualified mechanic to confirm compatibility before use.
Setup:
When changing gear oil, ensure the vehicle is safely supported on jack stands. Drain the old oil completely from the gearbox or differential. Remove any old sealant or debris from the drain and fill plugs. Using a suitable pump or funnel, fill the gearbox/differential with the correct amount of Millers Oils CRX LS NT+ Nanodrive 75W140 until it reaches the specified level (usually indicated by the bottom of the fill hole). Reinstall and tighten drain and fill plugs to the manufacturer's specified torque. It is recommended to have this procedure performed by a professional mechanic if you are not experienced with automotive driveline maintenance.
Care:
Gear oil does not have a fixed service interval as it depends heavily on application and driving conditions. For competition use, it is advisable to change the oil after each event or a set number of hours/miles. For high-performance road use, consult your vehicle manufacturer's recommendations or consider changing the oil every 20,000-30,000 miles, or sooner if experiencing any signs of wear or performance degradation. Store the unused oil in its original container in a cool, dry place, away from direct sunlight.
