Idemitsu CVT Type N3 Transmission Fluid — 6×1 Qt Pack, NS-3 Spec & Anti-Shudder

Idemitsu CVT Type N3 (NS-3) Transmission Fluid is a factory-compatible, high-performance fluid formulated specifically for Nissan CVTs that require NS-3 specification, sold here as six 1-quart bottles.

This Idemitsu NS-3 fluid is designed to meet the precise friction and sealing needs of many Nissan continuously variable transmissions. It balances smooth belt/pulley operation with anti-shudder properties and thermal stability so the transmission runs cleanly across a wide range of temperatures. The concentrate below explains what makes it suitable for NS-3 applications, what to expect during use, and who should choose this six-quart pack.

Which vehicles and transmissions is this Idemitsu CVT Type N3 fluid compatible with?

This fluid is intended for Nissan CVT units that explicitly call for NS-3 (also shown as Type N3) specification. It is not a universal transmission oil and should not be substituted for automatic, manual, or other CVT specifications unless your vehicle manual allows it.

• Specifically formulated to match Nissan NS-3 requirements.
• Suitable for CVT systems using belt/pulley friction control tuned to NS-3 chemistry.
• Not recommended for non-NS-3 transmissions or hybrid-specific CVT variants unless confirmed.

How does this fluid protect against shudder, heat, and deposits?

Idemitsu’s NS-3 formulation targets friction stability and resistance to oxidation, which reduces shudder and thermal breakdown. By maintaining consistent friction characteristics and resisting varnish formation, the fluid helps preserve smooth engagement and component cleanliness over time.

• Engineered friction modifiers to minimize belt or chain shudder.
• High oxidation resistance for extended service life under high temperatures.
• Deposit control additives to prevent sludge and varnish buildup inside the CVT.

What maintenance benefits come from using a six-pack of 1-quart bottles?

Buying this six-pack gives you enough fluid for routine service intervals or a single drain-and-refill for many Nissan CVT models. Individual 1-quart bottles make measuring and storing fluid simpler and reduce waste during partial top-ups or controlled service jobs.

• Six one-quart bottles for flexibility during service or multiple vehicles.
• Smaller bottles reduce overfill risk and make pouring cleaner during service.
• Cost- and time-efficient for DIYers and independent shops handling routine CVT service.

Are seals and internal components protected when using this Idemitsu NS-3 fluid?

The formula includes seal-conditioning agents to maintain elastomer flexibility and reduce the chance of leaks caused by shrinkage or hardening. Using the recommended NS-3 fluid helps preserve factory seal compatibility and reduces long-term leak risk compared with non-specified fluids.

• Seal conditioners help prevent drying and cracking of gaskets and O-rings.
• Maintains compatibility with OEM materials for reliable sealing performance.
• Reduces potential for service issues related to incompatible chemistries.

Who is this product for? This Idemitsu CVT Type N3 (NS-3) Transmission Fluid six-pack is aimed at Nissan owners, independent mechanics, and DIY enthusiasts who need OEM-spec CVT fluid for routine maintenance or complete fluid replacement. Choose it if your vehicle manual specifies NS-3, if you perform regular CVT services and prefer smaller, easy-to-store containers, or if you require an ISO- and IATF-certified fluid that focuses on friction control, thermal stability, and seal care. Avoid using it in transmissions that call for different specifications, and consult your owner’s manual or a technician if you’re unsure which fluid your model requires.
