Manual transmission oil <em>Nissan Note</em>: how to choose and replace correctly

Manual transmission Nissan Note (in bodies E11 And E12) is famous for its reliability, but only subject to timely maintenance. One of the key points is selecting and changing oil in manual transmission - a procedure that many owners underestimate, believing that “the mechanics do not require attention.” This is a dangerous misconception: improper lubrication or its degradation accelerates the wear of synchronizers, bearings and gears, which leads to loss of clarity of switching and even breakdown of the gearbox on runs over 150,000 km.

In this article we will look at what kind of oil is poured into the manual transmission. Nissan Note from the factory, which analogues are suitable for replacement, and how to carry out the procedure yourself - taking into account the nuances of the design. We will separately dwell on common mistakes that even experienced car owners make, and provide a checklist for quality control of work.

Original manual transmission oil for Nissan Note: What's in it from the factory?

From factory to mechanical boxes Nissan Note (including models with engines HR15DE, HR16DE And K9K diesel) transmission oil is filled Nissan MT-XZ Gear Oil 75W-80 (article KE908-99931). This is a synthetic oil with a package of additives optimized for gearboxes RS5F92A And RS6F94R, which are installed on Note different generations.

Features of the original oil:

• 🔹 Viscosity 75W-80 — ensures stable operation at temperatures from -40°C to +40°C, which is critical for Russian conditions.
• 🔹 API Specification GL-4 - Suitable for synchronized boxes where moderate sulfur and phosphorus content is required.
• 🔹 Long life — under normal operating conditions, does not lose properties up to 90,000 km (but the recommended replacement interval is 60,000 km).

Important: original oil Nissan MT-XZ is not "lifetime" despite what some dealers claim. In urban conditions (frequent traffic jams, short trips), it degrades faster due to heating and wear products.

⚠️ Attention: If your Nissan Note used in regions with extremely low temperatures (below -30°C), original oil 75W-80 may thicken. In this case, it is permissible to use oil with a viscosity 75W-90, but only if compatibility with the box is confirmed!

Analogues of the original oil: what can be filled instead Nissan MT-XZ?

Original oil is expensive (from 1,500 rubles per liter), so many owners are looking for high-quality analogues. Main rule: Oil must meet API GL-4 specification and viscosity 75W-80. Below are proven options:

Brand and name	Article	Viscosity	Specification	Notes
Mobil Mobilube 1 SHC 75W-80	152620	75W-80	API GL-4/GL-5	Suitable for synchronizer boxes made of copper and its alloys
Castrol Syntrans Transaxle 75W-90	157AF9	75W-90	API GL-4+	Higher viscosity - only for warm climates
Liqui Moly Hochleistungs-Getriebeoil 75W-80	3941	75W-80	API GL-4/GL-5	Good wear protection, but more expensive than analogues
Motul Gear 300 75W-80	105784	75W-80	API GL-4/GL-5	Popular among owners Note with mileage >100,000 km

When choosing an analogue, pay attention to:

• 🔧 Compatible with synchronizers - oils GL-5 may be aggressive to copper parts.
• 🔧 Temperature range - better for Siberia 75W-80, for the south is acceptable 75W-90.
• 🔧 Availability of certificates — avoid “no-name” brands without a confirmed specification.

When to change manual transmission oil Nissan Note: signs and intervals

Official regulations Nissan does not require manual transmission oil changes throughout the entire service life of the vehicle. However, this is only true for “ideal” operating conditions, which practically do not exist in Russia. Actual replacement intervals:

• 🚗 60,000 km — during city driving (frequent starts/stops, traffic jams).
• 🚗 90,000 km — with a mixed cycle (highway + city).
• 🚗 120,000 km - with predominantly highway operation.

Signs that it's time to change the oil immediately:

• 🔊 Crunching or grinding noise when changing gears (especially when cold).
• 🔊 Difficulty turning on 1st or reverse gear.
• 🔊 Extraneous vibrations at idle speed with the clutch depressed.
• 🔊 Darkening of the oil (visible on the dipstick or when draining) or the presence of metal shavings.

⚠️ Attention: If after changing the oil in the manual transmission Nissan Note appeared bearing hum, this may indicate wear. In this case, diagnostics of the box is required - new oil does not mask mechanical faults!

Step-by-step instructions: how to change the oil in a manual transmission Nissan Note on your own

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

• 🔧 New oil (2–2.5 liters, depending on the box).
• 🔧 Key on 10 mm (for drain plug).
• 🔧 Key on 24 mm (for filler plug).
• 🔧 Funnel with flexible hose (diameter ~8 mm).
• 🔧 Capacity for working out (volume of at least 3 liters).
• 🔧 Gloves and rags.

Sequence of actions:

1. Warm up the box: drive 5–10 km so that the oil becomes less viscous.

2. Raise the vehicle on a lift or ramp. An alternative is a jack with stops (but this is less convenient).

3. Remove the crankcase protection (if installed). The drain plug is located on the bottom of the box.

4. Place the container and unscrew the drain plug with a key 10 mm. Be careful - the oil will be hot!

5. Wait until it drains completely (10–15 minutes). Inspect the waste: if there are a lot of metal shavings in it, the box needs diagnostics.

6. Tighten the drain plug (tightening torque - 30–40 Nm).

7. Unscrew the filler plug (key on 24 mm, located on the side of the box).

8. Pour new oil through the funnel. Volume:

   • 🔹Box RS5F92A — 2.0 l.
   • 🔹Box RS6F94R — 2.3 l.

Screw in the filler plug and check the level: it should be at the bottom edge of the hole.

Check for new oil and tools|

Warm up the box (drive 5–10 km)|

Make sure there are no oil seal leaks|

Prepare a container for processing (minimum 3 l)|

Check the tightening torque of the plugs (30–40 Nm) -->

If after changing the oil continues to leak, check:

• 🔧 Condition of the drive shaft seal (a common cause of leakage).
• 🔧 Tightening the drain and filler plugs.
• 🔧 Integrity of the box body (cracks or damage after impacts).

Typical mistakes when changing oil in a manual transmission Nissan Note

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

1. Overfilling or underfilling oil. An insufficient level leads to oil starvation and accelerated wear, and an excess level leads to increased pressure and leaks through the seals. Optimal level - along the bottom edge of the filler hole.

2. Using oil of the wrong viscosity. For example, 80W-90 instead of 75W-80 impairs the performance of synchronizers in cold weather.

3. Ignoring metal shavings during mining. If chips are visible in the drained oil, the box requires flushing or repair. A simple oil change will not help here.

4. Tightening plugs without a torque wrench. Too much force can strip the threads in the aluminum box housing.

5. Mixing different types of oils. For example, mineral water with synthetics. This leads to foaming and loss of lubricating properties.

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

Long-term operation with old lubricant leads to:

- Wear of synchronizers (difficult gear shifting).

- Corrosion of gears and bearings (due to the accumulation of moisture and oxidation products).

- Increased transmission noise (hum, howl in neutral).

- In critical cases - jamming of the shaft or destruction of bearings, which requires major repairs (from 50,000 rubles).

Manual transmission flushing Nissan Note: when is it needed and how to do it?

Flushing the gearbox is required in three cases:

• 🔧 When switching from one type of oil to another (for example, from mineral water to synthetic).
• 🔧 If there are a lot of metal shavings in the drained waste or it has a strong burning smell.
• 🔧 After purchasing a used car with an unknown service history.

How to flush a manual transmission:

1. Drain the old oil (as described above).

2. Fill in flushing oil (For example, Liqui Moly Getriebe-Reiniger or Wynn’s TransFlush).

3. Raise the front wheel (box side) and start the engine. Engage 1st gear and let it run for 2-3 minutes.

4. Drain the flushing oil and fill with new transmission oil.

⚠️ Attention: Do not use for cleaning manual transmissions. Nissan Note kerosene, diesel fuel or aggressive solvents! They destroy oil seals and seals, which will lead to leaks.

Answers to frequently asked questions (FAQ)

Is it possible to use 75W-90 oil instead of 75W-80?

Yes, but only in warm climates (winter temperature not lower than -20°C). Oil 75W-90 thicker, which can impair the performance of synchronizers in the cold. Optimal for most regions of Russia 75W-80.

How much oil to fill in manual transmission Nissan Note E12?

The volume depends on the type of box:

• 🔹 RS5F92A (5-speed) - 2.0 l.
• 🔹 RS6F94R (6-speed) - 2.3 l.

Always check the level at the filler hole!

Do I need to flush the transmission when changing the oil?

Flushing is only necessary if:

• 🔧 There are a lot of shavings in the drained oil or it is black with a burning smell.
• 🔧 You are switching from mineral water to synthetics.
• 🔧 The vehicle's service history is unknown (for example, after purchasing a used one).

In other cases, a standard replacement is sufficient.

What kind of oil should I fill in a Nissan Note manual transmission with a K9K engine (diesel)?

For diesel versions Nissan Note with box RS5F92A The same oil is suitable as for gasoline - Nissan MT-XZ 75W-80 or its analogues (Mobil Mobilube 1 SHC, Motul Gear 300). Diesel does not impose additional requirements on gear oil.

What to do if the gears are difficult to engage after changing the oil?

Possible reasons:

• 🔧 Incorrect oil viscosity (for example, flooded 80W-90 instead of 75W-80).
• 🔧 Air entering the system (you need to drive the gearbox in all gears).
• 🔧 Synchronizer wear (needs renovation).

First check the oil level and type. If the problem remains, diagnose the box.
