Nissan 80W90 oil: which one to choose for the transmission and how to replace it correctly

Gear oil 80W90 - one of the most common options for manual transmissions, axles and gearboxes of cars Nissan. But why is this particular viscosity recommended by the manufacturer, and what nuances should be taken into account when choosing? In this article we will analyze not only the technical characteristics of the oil, but also tell you how to distinguish the original Nissan MT-XZ 80W90 from counterfeit, which analogs can be used without risk to the transmission, and how to properly replace it yourself.

Many owners Nissan Qashqai, X-Trail or Navara They are faced with the question: is it possible to fill in synthetics instead of mineral water, or should you adhere to the factory recommendations? We analyzed reviews from mechanics, technical bulletins Nissan and the results of laboratory tests of oils to provide clear recommendations. You will also find out what consequences await the transmission when using oil with unsuitable additives or exceeding the replacement interval.

What does the 80W90 marking mean and why does Nissan recommend it?

Marking 80W90 decrypted according to the standard SAE J306 and indicates the viscosity-temperature properties of the oil:

• 🔹 80W — winter viscosity class, guaranteeing oil pumpability at temperatures up to -26°C (real tests show that high-quality oils remain fluid even when -30°C).
• 🔹 90 — summer class, which determines viscosity at 100°C (usually in the range 13.5–18.5 mm²/s).

Manufacturer Nissan recommends this viscosity for manual transmissions (Manual transmission), transfer cases and rear axles of most models, including Pathfinder R51, Terrano II And NP300 Hardbody. The reason is simple: 80W90 oil provides an optimal balance between gear protection under high loads and ease of gear shifting in cold weather. For example, in Nissan Almera N16 with Manual transmission FS5W71C The factory provides this exact oil - more liquid options (like 75W80) can lead to accelerated wear of synchronizers.

However, it is important to understand that 80W90 is not a universal standard. For some models (eg Nissan Juke with Manual transmission JH3) the manufacturer may recommend 75W85, and for Patrol GR Y61 with locking differential - 85W140. Always check the manual!

Original Nissan MT-XZ 80W90 oil: composition and part numbers

Official gear oil from Nissan is called MT-XZ 80W90 and comes in two packaging options:

• 📦 KE900-90032 - canister 1 l (the most common item for retail sale).
• 📦 KE900-90042 - barrel 20 l (for service stations and dealer centers).

According to independent laboratories (including reports Oil Club), Nissan MT-XZ refers to semi-synthetic oils with a package of additives based on sulfur and phosphorus (Sulfur-Phosphorus). This provides:

• 🛡️ High oxidation resistance (service life up to 100,000 km under moderate loads).
• 🔧 Good compatibility with copper synchronizers (important for Manual transmission FS5R30A in Nissan Primera P12).
• 🌡️ Stable viscosity at temperatures from -30°C to +150°C.

However, there is a nuance: the original oil Nissan not produced by the company itself, but to order from Idemitsu Kosan (Japan) or Eneos. This means that the color (from amber to dark brown) and smell may vary slightly between batches, but this does not affect the quality.

⚠️ Attention: There are often fakes on the market Nissan MT-XZ in cans with uneven seams or misprinted labels. The original always has a holographic sticker on the lid and the production date stamped on the bottom of the canister.

Analogues of 80W90 for Nissan: what can be filled instead of the original

If the original oil is not available or its price seems too high, you can consider certified analogues. Main rule: oil must meet specifications API GL-4 or GL-5 (depending on transmission type). For most Manual transmission Nissan fits GL-4, and for bridges with hypoid gears (for example, in Nissan Patrol) — GL-5.

Brand	Oil name	Specification	Application	Average price (1 l)
Motul	Gear 300 80W90	API GL-4/GL-5	Manual transmission, transfer case, axles	1 200 ₽
Liqui Moly	Hypoid-Getriebeoil TDL 80W90	API GL-5	Axles with hypoid gears	1 100 ₽
Castrol	Axle EPX 80W90	API GL-5	Rear axles, gearboxes	950 ₽
Mobil	Mobilube HD 80W90	API GL-4	Manual transmission without hypoid gears	800 ₽

Important: if in your Manual transmission there are brass or copper synchronizers (as in Nissan Sunny B14), avoid high sulfur oils (GL-5), as they can accelerate wear. In this case it is better to choose GL-4 or specialized oils for synchronized gearboxes, for example, Red Line MT-90.

💡

Before purchasing an analogue, check its compatibility with the seal materials of your box. Some oils (such as polyalphaolefin oils) may cause rubber seals to swell in older models. Nissan (until 2005).

When and how often to change 80W90 oil in a Nissan transmission

Official recommendations Nissan according to oil change intervals Manual transmission and axles vary depending on the model and operating conditions:

• 🚗 Moderate climate, city driving: every 90,000–120,000 km.
• 🏔️ Severe conditions (off-road, towing, extreme temperatures): every 60,000 km.
• ❄️ Operation at temperatures below -30°C: replacement once every 2–3 years regardless of mileage (oil loses low-temperature properties).

However, there are models where the oil is in Manual transmission is considered "filled for life". For example, in Nissan Juke (2010–2019) with box JH3 the manufacturer does not provide for an oil change, but in practice after 100,000 km it loses its properties, and switching becomes less clear. Mechanics recommend replacing them once every 80,000–100,000 km regardless of the regulations.

Signs that it's time to change the oil:

• 🔊 Crunching or grinding noise when changing gears (especially when cold).
• 🛢️ Darkening of the oil (black color indicates the presence of wear products).
• 💨 Smell of burning (indicates overheating of the box).
• 🔄 Difficulty shifting gears (for example, first or reverse “do not go” the first time).

Drain the old oil (pre-heat the box to 50–60°C)|Check the drain and filler plugs for metal shavings|Rinse the box with a special liquid (if the oil is heavily contaminated)|Fill in new oil to the level of the filler hole|Check the operation of the box after replacement (switching should be smooth)-->

Step-by-step instructions for changing 80W90 oil in a Nissan manual transmission

To change the oil in a manual transmission Nissan you will need:

• 🔧 Key by 24 (for drain plug).
• 🔧 Key at 17 or hexagon (for the filler plug, depending on the model).
• 🛢️ Oil 80W90 (see table below for volume).
• 🧤 Gloves and container for working out (5 l).
• 🔥 Heat gun or hair dryer (to warm up the box if the oil is thick).

Oil volume for popular models Nissan:

Model	Box type	Oil volume (l)	Note
Nissan Qashqai J10	Manual transmission FS5R31A	2.8	The filler hole is located on the side
Nissan X-Trail T31	Manual transmission FS6R31A	3.2	Removal of engine protection required
Nissan Navara D40	Manual transmission FS6R51A	3.5	Drain plug under the back of the box
Nissan Almera N16	Manual transmission FS5W71C	2.5	Filler hole under the hood

Step by step process:

1. Warm up the box (drive 10–15 km or let the engine run 10 minutes at idle).
2. Lift the car on a lift or drive it into a pit. Remove protection (if any).
3. Unscrew the drain plug (key by 24) and drain the oil into a container. Attention: the oil will be hot!
4. Wipe the magnet of the drain plug from metal shavings (its presence is normal for used boxes > 100,000 km).
5. Screw on the drain plug with a new gasket (part no. 31397-31X01 for most models).
6. Unscrew the filler plug and use a syringe or funnel to fill in new oil up to the level of the hole.
7. Tighten the filler plug and check the operation of the box while driving.

⚠️ Attention: In boxes Nissan with a transverse engine (for example, Juke or Note) the filler hole may be on the passenger side. Do not confuse it with the hole for the speed sensor!

What to do if the oil does not drain?

If the oil does not flow even after warming up, the drain hole may be clogged or the plug is stuck. In this case:

1. Try gently tapping the cork with a hammer through a wooden spacer.

2. Use a penetrating lubricant (eg WD-40) and wait 10–15 minutes.

3. If it doesn’t help, contact service, as there is a risk of breaking the thread.

Typical mistakes when changing oil and their consequences

Even experienced car owners sometimes make mistakes that can lead to box failure. Here are the most common:

• 🚫 Overfilling or underfilling oil.
  — Consequences: Excess oil leads to foaming and loss of lubricating properties, too little leads to oil starvation of the gears.
  — How to avoid: Fill the oil strictly to the level of the filler hole.
• 🚫 Using oil with the wrong specification.
  — Consequences: GL-5 in a box with copper synchronizers will accelerate their wear, and GL-4 in an axle with hypoid gears will not provide sufficient protection.
  — How to avoid: check the requirements in the manual or on the plate under the hood.
• 🚫 Ignoring flushing when changing oil type.
  — Consequences: mixing mineral water and synthetics can cause the formation of sediment that clogs the channels.
  — How to avoid: when switching from mineral water to synthetic water, use flushing oil (for example, Liqui Moly Getriebe-Reiniger).
• 🚫 Tightening plugs without replacing gaskets.
  — Consequences: oil leakage and a decrease in its level.
  — How to avoid: always use new copper or aluminum gaskets (cost 50–100 ₽).

Particular attention should be paid to gearboxes with a locked differential (for example, in Nissan Patrol or Navara with package Off-Road). Here the oil must match API GL-5 LS (with low sulfur content), otherwise the differential lock will not work correctly.

Owner reviews: real experience of using 80W90 in Nissan

To get an objective picture, we analyzed reviews from owners Nissan on the forums (Drive2, Nissan-Club.ru) and in social network groups. Here are the key observations:

Pros of 80W90 oil:

• ✅ B Nissan Qashqai J10 with mileage 150,000 km after replacing with Motul Gear 300 The crunching sound disappeared when engaging second gear (user review @AlexQQ on Drive2).
• ✅ B Nissan X-Trail T31 with Manual transmission original oil Nissan MT-XZ served 110,000 km without loss of properties (laboratory analysis from Oil-Club).
• ✅ B Nissan Almera Classic oil change for Liqui Moly 80W90 eliminated vibrations at speed 90–110 km/h (review from the forum Nissan-Almera.ru).

Cons and problems:

• ❌ B Nissan Primera P12 after filling with cheap oil API GL-5 (instead of GL-4) through 20,000 km the third gear synchronizers needed to be replaced (user review @PrimeraFan).
• ❌ B Nissan Terrano II with mileage 250,000 km original oil Nissan MT-XZ began to leak through the secondary shaft oil seal - the culprit was a worn filler plug gasket (solution: replace the gasket + sealant Loctite 574).
• ❌ B Nissan Pathfinder R51 after changing the oil to Castrol Axle EPX extraneous noise appeared in the transfer case - the reason turned out to be incompatibility with the seal materials (solution: flushing + replacement with Mobilube HD).

Interesting fact: on Nissan Navara D40 with mileage > 300,000 km some owners use the oil successfully 75W90 (For example, Red Line MT-90), noting easier gear shifting in cold weather. However, this approach requires the synchronizers to be in perfect condition and is not recommended for most cars.

FAQ: Frequently asked questions about Nissan 80W90 oil

Is it possible to mix different 80W90 oils (for example, Nissan MT-XZ and Motul Gear 300)?

Mix oils not recommended, especially if they differ in base (mineral water + synthetics) or additive package. In emergency cases (for example, topping up on the road), you can mix oils of the same brand and specification (GL-4 or GL-5), but perform a complete replacement as soon as possible.

What is the difference between 80W90 oil and 75W90, and is it possible to fill the second one instead of the first?

The main difference is low temperature properties: 75W90 remains more fluid in the cold (up to -40°C), but may be less resistant to high loads. In most boxes Nissan replacement 80W90 on 75W90 acceptable if:

• The box is in good condition (mileage < 150,000 km).
• You live in a region with cold winters (below -25°C).
• Oil meets specification API GL-4 (for Manual transmission).

For axles and transfer cases it is better to stick to 80W90.

How to check the oil level in a Nissan manual transmission without a dipstick?

In most boxes Nissan The oil level is checked through the filler hole:

1. Place the car on a level surface.
2. Unscrew the filler plug (usually located on the side of the box).
3. The level should be at the edge of the hole. If the oil does not flow out, add more.
4. Screw the plug with a new gasket.

In some models (for example, Nissan Micra K13) the filler hole is located under the air filter - it will need to be removed.

What kind of oil should I put in the transfer case of the Nissan X-Trail T31?

For transfer case Nissan X-Trail T31 (models before 2013) officially recommended Nissan Matic D (for automatic dispensers) or Nissan MT-XZ 80W90 (for mechanical ones). Volume - 0.8 l. Important: if your X-Trail equipped with a system All Mode 4x4-i, use only Matic D, since 80W90 not compatible with hydraulic couplings.

What happens if you don’t change the oil in a Nissan manual transmission?

Ignoring oil changes leads to:

• 🔧 Accelerated gear wear (appearance of metal shavings).
• 🔊 Increased noise (howl or hum when moving).
• 🚗 Difficulty shifting gears (especially when cold).
• 💥 Box jamming (in critical cases).

Service life Manual transmission without an oil change rarely exceeds 200,000 km.
