Manual transmission Nissan Almera Classic (B10) - a unit that, with proper maintenance, is capable of working 200,000+ km without major repairs. However, many owners overlook one critical point: Transmission oil in manual transmission also requires replacement, albeit less often than motor. In the official manual, the manufacturer often indicates that the fluid is filled “for the entire service life,” but in practice this leads to accelerated wear of synchronizers and bearings - especially in Russian roads and climate.

In this article we will analyze which oil is suitable for manual transmission Almera Classic (including analogues of original fluids), how to check its level and condition yourself, and we will also give step-by-step instructions for replacement, taking into account the nuances of the box design. Let us separately dwell on the typical mistakes that owners make during maintenance - from incorrect choice of viscosity to ignoring crankcase flushing.

Official Nissan recommendations: what is filled from the factory

From factory to manual transmission Almera Classic (models 2006–2018) transmission oil is filled Nissan MT-XZ Gear Oil 75W-85 (article KE908-99931). This fluid meets specification API GL-4 and is optimized to work with brass-based synchronizers that are installed in this manual transmission. Important: the use of oils with class GL-5 is unacceptable - they contain aggressive additives that destroy the soft metals of synchronizers.

In some regions (for example, for markets with extremely low temperatures), the manufacturer allows the use of oil 75W-90 same series MT-XZ. However, for most climatic zones of Russia, it remains optimal 75W-85 — it ensures easy gear shifting even at −30°C and maintains a stable film when heated to +120°C.

  • 🔧 Article number of the original oil: KE908-99931 (75W-85) or KE908-99932 (75W-90)
  • 📋 Specification: API GL-4, JASO MA
  • ⚠️ Refill volume: 2.3–2.5 l (depending on year of manufacture)
  • 🔄 Replacement interval: every 90,000 km or 6 years (whichever comes first)
⚠️ Attention: If your box previously used oil of unknown origin or with class GL-5, before replacing it with the original MT-XZ be sure to wash the crankcase with a special liquid (for example, Liqui Moly Getriebe-Reiniger). Mixing incompatible additives leads to the formation of deposits on gears.

Analogs of original oil: what can be filled instead of Nissan MT-XZ

Original oil Nissan MT-XZ It is not always available in regional stores, and its price is higher than that of its analogues. Fortunately, there are several proven alternatives that fully meet the manufacturer's requirements:

Brand and name Viscosity Specification Article Notes
Mobil Mobilube 1 SHC 75W-85 75W-85 API GL-4, JASO MA 152620 Synthetic, improved anti-friction properties
Castrol Syntrans Transaxle 75W-90 75W-90 API GL-4+, JASO MA2 157ABF Suitable for cold regions
Liqui Moly Hochleistungs-Getriebeoil 75W-85 75W-85 API GL-4/GL-5, JASO MA 3031 Versatile, but contains a minimal amount of GL-5 additives
Motul Gear 300 75W-85 75W-85 API GL-4, JASO MA 105777 High anti-wear properties

When choosing an analogue, pay attention to JASO MA approvals — they guarantee compatibility with synchronizers made of non-ferrous metals. Oils with class JASO MA2 (For example, Castrol Syntrans) have improved friction properties, but their cost is 20–30% higher than standard GL-4.

Avoid universal oils labeled “GL-4/GL-5” - they contain a compromise additive package that can negatively affect the service life of the gearbox. Exception - Liqui Moly 3031, where the share of GL-5 additives is minimal.

When and why you need to change the oil in a manual transmission

Manufacturer Nissan in the manual for Almera Classic indicates that the transmission oil does not require replacement during the entire service life of the vehicle. However, this approach is valid only for ideal operating conditions: moderate climate, smooth roads, no towing. In reality, there are several factors that accelerate oil degradation:

  • 🌡️ Extreme Temperatures: Frequent starts at −25°C and above or operation at +35°C and above reduce the life of additives by 30–40%.
  • 🚗 Aggressive driving style: Sharp starts from a standstill, long towing of a trailer or driving at high speeds increase the load on the gears.
  • 💧 Moisture ingress: Condensation that forms during short trips in winter leads to the formation of an emulsion and corrosion of the bearings.
  • 🛣️ Bad roads: Frequent off-road driving or city potholes accelerates the wear of synchronizers, and wear products contaminate the oil.

Recommended replacement interval - every 90,000 km or 6 years. But there are signs that indicate the need for an unscheduled replacement:

  • 🔊 Crunching or grinding noise when changing gears (especially when cold).
  • 🔄 Tight inclusion 1st or 2nd gear.
  • 💨 Burning smell from under the hood after a long trip.
  • 🎨 Dark oil color (black or brown) when checking with a dipstick.
💡

If you buy Almera Classic with mileage, first check the condition of the oil in the manual transmission. Even if the previous owner claims that replacement was not required, the drained fluid is often contaminated with metal shavings or smells like burnt additives.

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

Changing the oil in a manual transmission Almera Classic - a procedure that can be performed independently if there is an inspection hole or a lift. You will need:

  • 🔧 24mm wrench (for drain plug).
  • 🔧 14 mm wrench (for filler plug).
  • 🛢️ Funnel with flexible hose (hose diameter - 8–10 mm).
  • 🧴 Flushing fluid (optional if the oil is heavily contaminated).
  • 🧤 Gloves and rags.

Sequence of actions:

  1. Warm up the box: drive 10–15 km so that the oil becomes less viscous. This will allow the maximum volume of waste to be drained.

  2. Place the car on a viewing hole or lift. Secure the wheels with chocks.

  3. Clean the drain plug (located at the bottom of the manual transmission housing) with a wire brush. Unscrew it with a 24 mm wrench, having previously placed the container for processing.

  4. Wait until the oil is completely drained (10–15 minutes). Pay attention to the color and presence of metal shavings.

  5. If the oil is very dirty, tighten the drain plug and fill in 1 liter of flushing fluid (for example, Liqui Moly Getriebe-Reiniger). Start the engine, engage 1st gear and let it run for 2-3 minutes. Drain the wash.

  6. Install a new sealing washer onto the drain plug (part no. 11026-01M02) and tighten it with a torque of 35–40 Nm.

  7. Unscrew the filler plug (14 mm wrench, located on the side of the crankcase). Using a funnel with a hose, add new oil until it begins to flow out of the filler hole.

  8. Tighten the filler plug with a torque of 25–30 Nm. Take it for a test drive, checking for ease of gear shifting.

Buy oil (2.5 l) and a new washer for the plug|Warm up the box (drive 10–15 km)|Prepare a container for working off (at least 3 l)|Clean the drain and filler plugs from dirt|Check the availability of tools (24 and 14 mm wrenches)-->

⚠️ Attention: Some owners try to fill the oil through the breather valve of the box, but this risks incomplete filling of the crankcase. Filling hole on Almera Classic located exactly on the side, and only through it can the correct level be guaranteed.

Typical mistakes when changing oil and their consequences

Even experienced car owners make mistakes when servicing manual transmissions, which later lead to expensive repairs. Here are the most common ones:

  • 🛢️ Underfilling or overfilling of oil:
    • Underfilling leads to "oil starvation" bearings and gears, accelerating their wear by 2–3 times.
    • Overfilling (more than 2.7 liters) causes the oil to foam, which disrupts lubrication and increases the load on the seals.
  • 🔧 Use of unsuitable additives: Adding third-party additives to the oil (for example, to “improve shifting”) often leads to the formation of deposits on the synchronizers. Original oil MT-XZ already contains all the necessary components.
  • 🧴 Mixing different types of oils: For example, topping up 75W-90 in 75W-85 changes viscosity characteristics, which can cause transmission noise when cold.
  • 🚿 Ignoring flushing: If metal shavings or emulsion are present in the old fluid, the new oil will quickly become contaminated and its properties will deteriorate after 10,000 km.

Another critical error - use of oils with viscosity 80W-90. These liquids are too thick for Almera Classic, especially in winter. This leads to:

  • Stiff gear shifting at −10°C and below.
  • Increased load on synchronizers, which reduces their resource.
  • Increased fuel consumption (up to 3–5%) due to increased friction losses.
💡

If after changing the oil there is extraneous noise in the box, stop using the car immediately. This may indicate incompatibility of the fluid with the synchronizer materials or air entering the system.

How to check the oil level and condition without changing it

Unlike automatic transmission, in manual transmission Almera Classic There is no dipstick to check the oil level. However, you can still control its condition through filler hole. Here's how to do it:

  1. Place the car on a flat surface (no slope).

  2. Clean the filler plug (14 mm wrench) from dirt to prevent debris from getting into the box.

  3. Unscrew the plug. Normally, the oil should be level with the bottom edge of the hole. If it does not flow out, the level is insufficient.

  4. Assess the condition of the oil:

    • ✅ Norm: light brown or amber color, no burning smell, no visible metal particles.
    • ⚠️ Requires replacement: dark brown or black color, smell of burnt oil, presence of chips.
    • ❌ Critical condition: emulsion (whitish tint), strong metallic luster, thick consistency.

  • If the level is low, add the same type of oil through the funnel until it begins to flow out of the hole.

    • It is recommended to check every 30,000 km or when there are signs of a box malfunction. If the oil is in critical condition (point ❌), it will require not only its replacement, but also diagnostics of the box for wear of bearings or gears.

    What to do if the oil in the manual transmission turns dark 10,000 km after replacement?

    Darkening of the oil after a short period of time may indicate:

    1. Poor crankcase flushing — the remnants of the old fluid mixed with the new one.

    2. Intensive wear of synchronizers (for example, due to aggressive driving).

    3. Moisture ingress through a damaged breather or seals.

    In this case, it is recommended to repeat the replacement with mandatory flushing and check the condition of the breather (part number 32026-31X00).

    Frequently asked questions about oil in Almera Classic manual transmission

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

    Yes, but only if you operate the car in a region with extremely low temperatures (below −30°C). Viscosity 75W-90 slightly higher, which may make it slightly difficult to change gears when cold, but will not harm the transmission. For most regions of Russia, it remains optimal 75W-85.

    How much oil is needed for a complete change in the Almera Classic manual transmission?

    The volume depends on the year of manufacture:

    • 2006–2012 — 2.3 l.
    • 2013–2018 — 2.5 l.

    Buy oil with a reserve (3 liters), since some of the liquid will remain in the channels of the box.

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

    The consequences depend on the mileage:

    • 100,000–150,000 km: Stiff gear shifting, crunching noise when shifting into reverse gear.
    • 150,000–200,000 km: wear of synchronizers, increased gearbox noise.
    • 200,000+ km: destruction of bearings, jamming of shafts, the need for major repairs (cost from 30,000 ₽).

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

    Flushing is required in the following cases:

    • If the oil has not been changed for more than 120,000 km.
    • If metal shavings or emulsion are visible in the mining.
    • If you are switching from one type of oil to another (for example, from mineral to synthetic).

    For flushing, use specialized fluids (for example, Liqui Moly Getriebe-Reiniger) or original oil Nissan MT-XZ as a flushing agent.

    What kind of oil is poured into the Almera Classic manual transmission from the factory?

    Filled from the factory Nissan MT-XZ Gear Oil 75W-85 (article KE908-99931). Some batches of cars for cold regions may have used oil 75W-90 the same series. Both options meet specification API GL-4.
