Manual transmission oil <em>Nissan Almera N16</em>: how to select and replace without errors

Nissan Almera N16 with a manual transmission is a reliable car, but its transmission requires proper maintenance. Many owners mistakenly believe that the oil in a manual transmission does not need to be changed, but this is a myth: over time, the lubricant loses its properties, which leads to increased wear of synchronizers and bearings. In this article we will look at which oil is suitable for manual transmission Almera N16, how to replace it correctly and what mistakes can shorten the service life of the box.

Feature Almera N16 (2000–2006) is that its manual transmission (RS5F31A or RS5F32A) is sensitive to oil quality. The manufacturer recommends using only certain types of lubricants, but there are worthy analogues on the market. We analyzed data from manuals, reviews from owners and advice from technicians to create a complete guide - from choosing oil to the nuances of replacement.

Original oil for manual transmission Nissan Almera N16: what is filled from the factory

From factory to manual transmission Almera N16 oil is poured Nissan MT-XZ Gear Oil 75W-85 (article KE908-99932). This is a semi-synthetic gear oil with a package of additives optimized for gearboxes Nissan with synchronizers made of brass. Its key features:

• 🔹 Viscosity 75W-85 — ensures stable operation at temperatures from -40°C to +45°C.
• 🔹 Specification API GL-4 - Suitable for boxes with moderate loads.
• 🔹 Compatibility with synchronizers made of non-ferrous metals - prevents their premature wear.

However, the original oil Nissan has two drawbacks: high price (from 1,500 rubles per liter) and limited availability in the regions. Many owners have success using analogues, but it is important to consider their compliance with specifications.

⚠️ Attention: Oils with class GL-5 not suitable for manual transmission Almera N16! They contain aggressive additives that destroy brass synchronizers. Use only GL-4 or GL-4/5 marked "for synchronized boxes".

Analogues of the original oil: what to choose for replacement

If the original oil Nissan MT-XZ is not available, you can use proven analogues. The main thing is to maintain viscosity 75W-85 or 75W-90 and class GL-4. The best options in terms of price/quality ratio:

Brand and name	Article	Viscosity	Specification	Approximate price (1 l)
Mobil Mobilube 1 SHC 75W-90	152620	75W-90	GL-4/5	1,200–1,400 rub.
Castrol Syntrans Transaxle 75W-90	156E9	75W-90	GL-4+	1,300–1,500 rub.
Liqui Moly Hochleistungs-Getriebeoil 75W-90	3941	75W-90	GL-4/5	1,100–1,300 rub.
Motul Gear 300 75W-90	105784	75W-90	GL-4/5	1,400–1,600 rub.

Among budget options, oil has proven itself well ZIC G-FF 75W-85 (GL-4, article 162629) - it is cheaper (about 800 rubles/l), but requires more frequent replacement (every 60–70 thousand km).

Oil volume in manual transmission Almera N16: how much to fill

Oil volume in manual transmission Nissan Almera N16 depends on the type of gearbox:

• 🔧 RS5F31A (5-speed) - 2.8–3.0 liters.
• 🔧 RS5F32A (5-speed, less common) - 2.6–2.8 liters.

For a complete replacement with flushing you will need 3.5–4 liters oil (taking into account the remains in the box). If you change the oil partially (without flushing), 2.5–2.7 liters is enough.

⚠️ Attention: Underfilling the oil by 100–200 ml is more critical than overfilling. If the level is insufficient, the shaft bearings run dry, which leads to their destruction. Overfilling (up to 300 ml) is less dangerous, but can cause oil foaming and leakage through the seals.

Important: In boxes Almera N16 With a mileage of more than 150 thousand km, it is not recommended to use oil with a viscosity of 75W-80 - it is too thin for worn synchronizers and can cause noise when switching.

When to change manual transmission oil: regulations and signs of wear

Official regulations Nissan does not provide for manual transmission oil changes Almera N16 — it is considered “filled for its entire service life.” However, in practice this is not the case:

• 📅 First replacement - after 80–100 thousand km (or 5–6 years), even if there are no signs of wear.
• 🔄 Subsequent replacements — every 60–70 thousand km (or 4 years).
• ⚠️ Emergency replacement - when there is noise, difficult switching or metal shavings on the probe.

Signs that it's time to change the oil:

• 🔊 Crunching or grinding noise when changing gears (especially when cold).
• 🛑 Tight engagement of first or reverse gear.
• 💨 The smell of burning from the box (indicates overheating of the oil).
• 🩸 Dark color of oil on dipstick (should be light brown).

Step-by-step instructions for changing the oil in a manual transmission

Changing the oil in a manual transmission Almera N16 does not require special equipment, but an inspection hole or lift is required. You will need:

• 🔧 24 mm wrench (for drain plug).
• 🔧 17 mm wrench (for filler plug).
• 🔧 Funnel with flexible hose (diameter 8–10 mm).
• 🔧 Container for draining (volume of at least 4 l).
• 🔧 Gloves and rags.

Procedure:

1. Warm up the box — drive 5–10 km so that the oil becomes more fluid.
2. Drive the car into the pit and lock the handbrake. Support the rear wheels with chocks.
3. Drain the old oil:
   • Unscrew the drain plug (lower plug on the gearbox housing).
   • Wait until it drains completely (10–15 minutes).
   • Wipe the plug and install a new sealing washer (copper or aluminum).
4. Wash the box (optional):
   • Fill in 1 liter of new oil and tighten the plug.
   • Start the engine, engage 1st gear and let it run for 2-3 minutes.
   • Drain the flushing oil.
5. Fill with new oil:
   • Unscrew the filler plug (located on the side of the crankcase, closer to the passenger compartment).
   • Use a funnel with a hose to fill the oil to the bottom edge of the filler hole.

Check the level - it should be at the level of the edge of the hole (not lower and not higher).

If you don’t have a pit, you can pour oil through the dipstick hole (if your modification has one). To do this:

1. Pull out the dipstick (located next to the battery, under the air duct).
2. Insert a funnel into the dipstick hole and add oil.
3. Check the level using the dipstick - it should be between the marks MIN And MAX.

Common mistakes when changing oil and how to avoid them

Even experienced car owners make mistakes when changing manual transmission oil. Almera N16. Here are the most common:

• 🛢️ Use of oil GL-5 instead of GL-4 — leads to the destruction of synchronizers within 20–30 thousand km.
• 🔧 Re-tightening the drain plug — can break the threads in the aluminum gearbox housing.
• 💧 Not adding enough oil — causes oil starvation of bearings and accelerated wear.
• 🧴 Mixing different oils - even oils that are compatible according to specifications can conflict with additives.
• 🚗 Replacement without warming up the box — the old oil is not completely drained, the residue impairs the properties of the new one.

Another common mistake is ignoring the condition of the transmission breather. If it is clogged, excess pressure is created in the box, which leads to oil leaks through the seals. Before changing the oil be sure to clean the breather (located on the top of the crankcase, next to the speedometer drive).

What happens if you pour GL-5 oil into an Almera N16 manual transmission?

Oil class GL-5 contain sulfur-phosphorus additives that are aggressive to non-ferrous metals. In boxes Almera N16 synchronizers are made of brass, and these additives literally “eat” their surface, causing:

• 🔊 Crunch when changing gears.
• 🛑 Spontaneous speed loss.
• 💥 Breakdown of synchronizers (repair will cost 15–20 thousand rubles).

If you accidentally uploaded GL-5, drain it as soon as possible and flush the box with new oil GL-4.

Frequently asked questions about manual transmission oil Nissan Almera N16

Can I use 80W-90 oil instead of 75W-85?

Yes, but only in hot climates (where temperatures rarely drop below -10°C). Oil 80W-90 thicker in cold weather, which can cause difficult gear shifting during cold starts. In most regions of Russia it is better to follow the recommendation 75W-85 or 75W-90.

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

Flushing is required if:

• 🔄 The oil has not been changed for more than 100 thousand km.
