Gear oil MT XZ Gear Oil 75W-80 - one of the most recommended solutions for manual transmissions Nissan, but its selection and replacement often raise questions among owners. Why this particular viscosity? How does the original oil differ from analogues? And how to replace it correctly so as not to damage the transmission?
In this article we will look at technical specifications oils MT XZ Gear Oil 75W-80, compare it with popular substitutes (including Nissan KE908-99932 And Mobilube 1 SHC 75W-80), and we will also give step-by-step instructions for replacement, taking into account the characteristics of the models Nissan Qashqai, X-Trail, Juke and others. We will pay special attention critical errors when choosing oil, which can lead to premature wear of synchronizers or bearings.
What is MT XZ Gear Oil 75W-80 and why is it recommended for Nissan
MT XZ Gear Oil 75W-80 - this is semi-synthetic gear oil, developed specifically for manual transmissions taking into account the requirements of Japanese car manufacturers, including Nissan. Its key feature is stable viscosity in a wide temperature range: from -40°C to +120°C, which is critical for regions with sudden climate changes.
Why exactly 75W-80? This classification according to SAE means that the oil remains fluid in cold weather (index 75W) and provides reliable lubrication under high loads (index 80). In comparison, thicker oils (e.g. 80W-90) can make it difficult to change gears in the cold, and too fluid (for example, 75W) - unable to cope with stress in hot weather.
- ✅ Compatible with synchronizers: Special additives prevent wear of brass parts, which is important for manual transmissions Nissan with aluminum crankcase.
- ✅ Oxidation resistance: Extends the replacement interval to 80–100 thousand km (under normal operating conditions).
- ✅ Noise reduction: Reduces bearing noise and grinding noise when changing gears over 150 thousand km.
However, not all oils are labeled 75W-80 are the same. For example, MT XZ Gear Oil meets the standard API GL-4, while some analogues (for example, Castrol Syntrans Transaxle 75W-90) have a class GL-4/5, which may be excessive for most manual transmissions Nissan and even harmful to synchronizers.

Original vs analogs: comparison of MT XZ Gear Oil with popular substitutes
Original oil Nissan MT XZ Gear Oil 75W-80 (article KE908-99932) are often compared with analogues from Mobil, Castrol And Liqui Moly. To make an informed choice, consider their key differences in the table:
| Parameter | MT XZ Gear Oil 75W-80 | Mobilube 1 SHC 75W-80 | Castrol Syntrans Transaxle 75W-90 | Liqui Moly Hochleistungs-Getriebeoil 75W-80 |
|---|---|---|---|---|
| Basic basis | Semi-synthetics | Full synthetic | Semi-synthetics | Synthetic (Pao) |
| API class | GL-4 | GL-4/5 | GL-4/5 | GL-4 |
| Pour point | -45°C | -50°C | -42°C | -48°C |
| Price (1 l), rub. | ~1 200 | ~1 500 | ~1 300 | ~1 600 |
| Features | Nissan Approved, Synchromesh Optimized | High temperature stability, suitable for automatic transmissions with wet clutch | Versatile, but can be aggressive to brass | Increased wear protection, recommended for turbocharged engines |
⚠️ Attention: Oils with class GL-5 (or universal GL-4/5) contain an increased amount of sulfur and phosphorus, which accelerates the wear of synchronizers in manual transmissions Nissan. If the car manual states GL-4 only, avoid all-purpose oils!
For most models Nissan (For example, Qashqai J10/J11, X-Trail T31/T32) the optimal choice remains the original MT XZ Gear Oil or its full analogue - Mobilube 1 SHC 75W-80 (if improved thermal stability is required). For older models (eg Almera N16) can be considered Liqui Moly taking into account its high extreme pressure properties.
Which Nissan models require 75W-80 oil: complete list
Oil MT XZ Gear Oil 75W-80 Recommended for most manual transmissions Nissan, but there are nuances depending on the model and year of manufacture. Below is a list of cars for which this viscosity is mandatory (data from service manuals):
- 🚗 Nissan Qashqai (J10, J11) - manual transmission
RS6F92A,RS6F94R(oil volume: 2.8–3.0 l). - 🚙 Nissan X-Trail (T31, T32) - manual transmission
RS6F92A,FS6R31A(volume: 2.9–3.2 l). - 🚘 Nissan Juke (F15) - manual transmission
RS6F92A(volume: 2.6 l). - 🚖 Nissan Almera (N16, G15) - manual transmission
RS5F92A(volume: 2.7 l). - 🚕 Nissan Note (E11, E12) - manual transmission
RS5F92A,RS6F92A(volume: 2.5–2.8 l).
⚠️ Attention: For models with manual transmission FS5R50A (For example, Nissan Primera P12) oil required 75W-90, not 75W-80! Using the wrong viscosity will result in increased bearing wear and difficult gear shifting in the cold.
Also note oil volume: For full replacement in most boxes Nissan 2.8–3.2 liters are required, but in some cases (for example, after repairs) up to 3.5 liters may be needed. Always check the level using the inspection hole!
How to check the oil level in a Nissan manual transmission?
1. Place the car on a level surface.
2. Unscrew the control plug (usually located on the side of the manual transmission housing).
3. The oil level should be at the bottom edge of the hole. If the oil does not flow out, add more.
4. Tighten the plug with a torque of 35–40 Nm (do not overtighten!).
Step-by-step instructions for changing the oil in a Nissan manual transmission
Changing transmission oil in manual transmission Nissan - a procedure that can be performed independently if there is an inspection hole or a lift. The main thing is to be consistent and use the right tools.
10 mm square wrench (for drain plug)|24 mm socket wrench (for fill plug)|Oil syringe or funnel with flexible tube|New MT XZ Gear Oil 75W-80 (3-3.5 L)|New sealing washer for drain plug|Rag and waste container (minimum 4 L)
-->
Step 1. Preparing the car
Warm up the engine to operating temperature (5-10 minutes of driving) so that the oil becomes more fluid. Place the car on a viewing hole or lift. Turn off the engine and secure the wheels with the hand brake.
Step 2. Drain the old oil
Place a container under the drain hole (usually located at the bottom of the manual transmission housing). Using a 10 mm wrench, unscrew the drain plug and wait until the oil is completely drained (may take 15–20 minutes). Pay attention to the color and consistency of the waste:
- 🟢 Light brown — the oil is in good condition.
- 🟡 Dark with metal particles - washing required.
- ⚠️ Black with a burnt smell — critical wear of the box, diagnostics are needed.
Step 3. Filling with new oil
Tighten the drain plug with a new sealing washer (tightening torque: 35 Nm). Unscrew the filler plug (usually located above the drain, closer to the passenger compartment). Using a syringe or funnel with a tube, add new oil until it begins to flow out of the inspection hole. Tighten the plug.
⚠️ Attention: Do not use flushing fluids for manual transmission! They can damage the synchronizers. If the oil is heavily contaminated, perform double replacement: after the first drain, fill in new oil, drive 500 km and repeat the procedure.
If the gear shifts are difficult after changing the oil, check the oil level - you may have overfilled it. Excess oil creates excess pressure in the crankcase and makes it difficult for the synchronizers to operate.
Common mistakes when choosing and changing oil
Even experienced car owners make mistakes that can reduce the life of a manual transmission. Here are the most critical of them:
- ❌ Using GL-5 oil instead of GL-4: Leads to corrosion of synchronizers (especially important for gearboxes
RS6Fseries). - ❌ Mixing oils from different manufacturers: Even if the viscosity is the same, the additives may react and form sediment.
- ❌ Failure to comply with replacement intervals: In city conditions, oil ages faster - it is recommended to replace it every 60–80 thousand km, and not 100 thousand km, as the manufacturer indicates.
- ❌ Ignoring the inspection hole: Overfilling or underfilling oil by 200–300 ml impairs bearing lubrication.
Another common mistake is buying fake oil. Original MT XZ Gear Oil Supplied in plastic canisters with a holographic sticker and production date on the bottom. Fakes often have:
- 🔹 Uneven seams on the canister.
- 🔹 Lack of serial number.
- 🔹 The consistency is too liquid (you can check by dropping oil on paper - the original does not spread instantly).
If you doubt the originality of the oil, buy it only from official Nissan dealers or trusted suppliers such as Exist.ru or Autodoc.
