Nissan Almera Classic (also known as Nissan Sunny B10 in some markets) is one of the most reliable budget sedans, but even its manual transmission requires regular maintenance. Many owners mistakenly believe that manual transmission oil is filled “for its entire service life,” however The manufacturer's regulations provide for replacement every 90–120 thousand km - especially if the car is operated in difficult conditions (city traffic jams, frequent switching, towing).
In this article you will find step-by-step instructions for changing the oil in a manual transmission Almera Classic, including choosing the right transmission fluid, the tools needed, and common mistakes newbies make. We will also look at why ignoring this procedure can lead to premature wear of synchronizers and bearings - problems that cost many times more than timely maintenance.
When to change the oil in a Nissan Almera Classic manual transmission?
Official regulations Nissan for models with manual transmission (including FS5W71C, installed on Almera Classic) provides checking the oil level every 30 thousand km, and replacement - once every 90–120 thousand km. However, these figures are relevant for “ideal” operating conditions. In reality, the time frame is reduced:
- 🚗 City mode with frequent starts/stops - replacement every 60–70 thousand km.
- 🏔️ Driving on off-road or mountain serpentines — check the level every 15 thousand km, replace it every 80 thousand km.
- 🔥 Extreme temperatures (hot climate or frosts below −30°C) - reduce oil life by 20–30%.
- 🚛 Towing a trailer or overloading a vehicle — increases the load on the gearbox, requiring replacement every 50–60 thousand km.
How to understand when it's time to change the oil ahead of schedule? Pay attention to the symptoms:
- 🔊 Crunching or grinding noise when changing gears (especially when cold).
- 🔄 Tight inclusion first or second gear.
- 💨 Burning smell from under the hood (may indicate oil overheating).
- 🛢️ Darkening or cloudiness of oil on the dipstick (if your modification has one).
⚠️ Attention: If found in oil metal particles (shavings, sawdust), this is a signal about critical wear of gears or bearings. In this case, changing the oil will not solve the problem - diagnostics of the box is required!
What kind of oil should I fill in the Nissan Almera Classic manual transmission?

Step-by-step instructions: how to change the oil in a manual transmission
Procedure for changing oil in a manual transmission Almera Classic takes 40–60 minutes (without rinsing). Follow the algorithm:
Step 1: Warm up the oil
Start the engine and let it run 5–10 minutes, or drive 10–15 km. Warm oil drains faster and more completely. Don't overheat — the oil temperature should not exceed 60°C (you can check it with your hand on the dipstick).
Step 2: Drain the old oil
1. Drive the car to pit or lift (you can use a jack, but be sure to secure the car with jack stands!).
2. Clean drain plug (located at the bottom of the box) with a wire brush to remove dirt.
3. Place the container and unscrew the cap using the key 24 mm. Be careful - the oil may be hot!
4. Wait until it drains completely (10–15 minutes). If the oil is dark or contains chips, it is required flushing.
How to check chips in oil?
Place the magnet in the drained liquid for 5-10 minutes. If metal particles remain on it, this is a sign of gear wear. Large chips (visible to the naked eye) indicate the need to repair the box.
Step 3: Wash the box (optional)
If the drained oil is dirty or contains wear debris:
- Screw in the drain plug.
- Fill through the filler hole 1.5–2 liters of flushing fluid.
- Start the engine and let it run 5–10 minutes in neutral gear.
- Drain the wash and repeat the procedure with clean oil (if there are any chips left).
Step 4: Add new oil
1. Make sure that the drain plug is tightened (the tightening torque is 30–40 Nm).
2. Unscrew filler plug (17 mm wrench, located on the side of the box).
3. Use a syringe or funnel with a flexible tube to add oil. Volume - 2.8–3.0 liters (until it starts to flow out of the filler hole).
4. Tighten the plug (torque - 25–30 Nm).
If you don’t have a syringe, you can use a plastic bottle with the bottom cut off and a hose attached to the neck. Fill the oil slowly to avoid air pockets.
Step 5: Checking the Level
In most modifications Almera Classic no dipstick — the level is checked through the filler hole. If the oil does not flow out when the plug is unscrewed, add more 100–200 ml.
After changing the oil, avoid sharp acceleration and towing for the first 100–200 km - this will help the new oil to be evenly distributed throughout the transmission.
Typical mistakes when changing oil in a manual transmission
Even experienced car owners make mistakes that can lead to oil leak or box failure. The most common:
- 🔧 Cork retightening - leads to thread failure or deformation of the copper washer. Use a torque wrench!
- 🛢️ Underfilling or overfilling of oil:
- Underfilling (< 2.5 l) causes oil starvation and accelerated wear.
- Overflow (> 3.2 l) creates excess pressure and can squeeze out the seals.
- 🔄 Using GL-5 oil instead of GL-4 — destroys synchronizers.
- 🧴 Ignoring flushing If the oil is heavily contaminated, new additives will not be able to compensate for wear.
- 🚗 Changing the oil to cold — up to 300–500 ml of old oil remains in the box.
Another critical error - using sealant on plug threads. This leads to:
- 🔩 Difficulty unscrewing during the next replacement.
- 💧 Sealant particles getting into the oil (clogs the channels).
⚠️ Attention: If after changing the oil there is noise or vibration When driving, immediately check:
- Oil level (possibly underfilled).
- Tightening the plugs (may be leaking).
- Oil quality (fake or incorrect specification).
How much does it cost to change the oil in an Almera Classic manual transmission?

Frequently asked questions about changing the oil in a Nissan Almera Classic manual transmission
Is it possible to mix different oils in a manual transmission?
No! Even if both oils meet specification GL-4, their additives may react, leading to loss of properties or the formation of sediment. If you need to add oil, use same brand and viscosity, which was filled in earlier.
What happens if you don’t change the oil in your manual transmission?
Over time, the oil loses its lubricating properties, which leads to:
- 🔊 Increased noise when the box is working.
- 🔄 Difficulty shifting gears (especially when cold).
- 🛠️ Wear of synchronizers (repair cost - from 15,000 ₽).
- 🔥 Overheating of the box and bearing failure.
Do I need to flush the transmission when changing the oil?
Flushing is required if:
- Drained oil dark or cloudy.
- Visible in oil metal shavings.
- The oil has not been changed more than 120 thousand km.
- The car was used in difficult conditions (taxi, off-road).
In other cases it is enough double flush: after the first drain, fill in 1 liter of new oil, turn the box in neutral (start the engine for 2-3 minutes), then drain and fill the full volume.
How to check the oil level in a manual transmission without a dipstick?
B Almera Classic level is checked through filler hole:
- Place the car on flat surface.
- Unscrew the filler plug (17 mm wrench).
- If oil does not leak - its level is below normal. Top up until a leak appears.
- Tighten the plug.
What kind of oil is poured into the Almera Classic manual transmission from the factory?
From factory to box Nissan Almera Classic (2006–2018) oil is added Nissan KE908-99932 (75W-80, GL-4). However, when replacing, you can use analogues from Mobil, Castrol or Liqui Moly with the same specifications (see table above).
