The Millers Oils CRX LS NT+ 75W90 is a fully synthetic gear oil designed for high-performance manual transmissions and axles, particularly those with plate-type limited-slip differentials (LSDs) requiring GL-4 or GL-5 specifications. Its key benefit is the advanced Nanodrive technology, which drastically reduces wear and friction, leading to lower power loss and enhanced component protection. A potential caveat is its specialized formulation, which may not be suitable for all gearbox types; always consult your vehicle's manual.

'LS' stands for Limited Slip, indicating that the oil is formulated with specific friction modifiers to ensure optimal performance and smooth engagement in limited-slip differentials.
Yes, while it's specifically designed for LSDs, the CRX LS NT+ can be used in manual transmissions and axles without an LSD if they require a GL-4 or GL-5 specification. The Nanodrive technology will still provide superior wear protection and reduced friction.
GL-4 oils typically contain less extreme pressure additive and are suitable for synchronized manual transmissions. GL-5 oils have higher levels of extreme pressure additives, designed for heavily loaded gears like those in differentials, and can sometimes be too corrosive for yellow metals found in older synchronizers. CRX LS NT+ meets both specifications, offering a balance for mixed applications.
It is recommended to follow the oil change intervals specified by your vehicle manufacturer. For high-performance or motorsport use, more frequent changes are advisable, typically between 10,000-20,000 miles or annually, depending on usage severity.
It is generally not recommended to mix different types of gear oils, especially fully synthetic with mineral oils or oils with different specifications. For best performance and to ensure the integrity of the Nanodrive technology, use Millers Oils CRX LS NT+ as a standalone fill.
Nanodrive Technology uses advanced spherical nanoparticles that create a super-smooth, low-friction surface on metal components. These particles provide exceptional protection under extreme pressure by 'filling' microscopic imperfections without compromising the oil's overall viscosity or performance.
Ensure the correct oil viscosity (75W90) and specification (GL-4/GL-5) are used. The CRX LS NT+ is designed for improved cold flow, but extremely low temperatures might still affect shifting. Check for any physical obstructions or wear in the gearbox linkage.
While CRX LS NT+ contains friction modifiers for smooth LSD operation, some initial noise may occur as the oil seats. If persistent, verify that the LSD is indeed a plate-type unit and that no other mechanical issues are present. Ensure the oil is filled to the correct level.
Check that all drain and fill plugs are securely tightened to the manufacturer's recommended torque. Inspect seals and gaskets for damage or wear; if damaged, they should be replaced. This oil is fully synthetic and generally safe for most seals, but always confirm compatibility if using in a very old or modified system.
Compatibility: This oil is recommended for modern manual transmissions and axles that specify a synthetic oil with API GL-4, GL-5, or MT-1 performance. It is particularly suitable for gearboxes and differentials equipped with plate-type limited-slip differentials (LSDs). Always consult your vehicle manufacturer's service manual or a qualified technician to confirm the correct oil specification before use. It is compatible with ZF TE-ML specifications 02B, 05B, 05D (limited slip), 07A, 12B, 16F, 17B, 19C, and 21B.
Setup: Ensure the gearbox or axle is completely drained of old oil. Remove the fill plug and drain plug. Allow the old oil to drain fully. Replace the drain plug, tightening to the manufacturer's specified torque. Fill the unit with the correct amount of Millers Oils CRX LS NT+ 75W90 through the fill hole until the oil level reaches the bottom of the fill hole (or as specified by the manufacturer). Replace the fill plug, tightening to the specified torque.
Care: Store the oil in a cool, dry place, away from direct sunlight. Keep the container tightly sealed to prevent contamination. While the Nanodrive technology provides superior wear protection, regular oil changes according to your vehicle's service schedule are still recommended, especially for high-performance or track use vehicles.
