Nissan Almera Classic (known in some countries as Samsung SM3) is one of the most popular budget sedans in the post-Soviet space. Despite the simplicity of the design, even such a reliable machine requires timely maintenance, especially when it comes to manual transmission. Many owners mistakenly believe that the oil in the manual transmission Almera Classic filled “for the entire service life”, but this is far from true.
In this article we will analyze what oil does the manufacturer recommend?, what analogues can be used without risk to the box, how often to change it and what will happen if you ignore the replacement. You will also find step-by-step instructions with photos, how to change the oil yourself, without resorting to the services of a service station. We will pay special attention critical errors during replacement, which can lead to failure of the manual transmission after 10–15 thousand km.
Official Nissan oil recommendations for Almera Classic manual transmission
Manufacturer Nissan in the manual for Almera Classic (body B10, 2006–2012) indicates that the oil in the manual transmission does not require replacement during the entire service life of the vehicle. However, this statement is true only for “ideal” operating conditions: moderate climate, smooth roads, no overloads. In reality:
- 🔥 High temperatures (hot climate, traffic jams) accelerate oil degradation by 2–3 times.
- ❄️ Frost below -20°C make the oil thick, increasing the load on the synchronizers.
- 🚗 Aggressive riding (sharp starts, towing) leads to overheating of the box.
- 💧 Moisture ingress through the breather or seals causes corrosion of gears.
Therefore, experienced technicians recommend changing the oil in the manual transmission. Almera Classic every 60–90 thousand km (or once every 4–5 years), and in severe conditions - every 40–50 thousand km. Ignoring this procedure risks:
⚠️ Attention! With a mileage of over 100 thousand km without changing the oil in the manual transmission Almera Classic the risk of bearing chipping and synchronizer wear increases by 70%. The first symptoms are a crunching sound when switching to 2nd or 3rd gear, as well as spontaneous shifting of gears.
Now about the oil itself. The official manual instructs to use gear oil with API GL-4 classification and viscosity 75W-80 or 75W-90. Original liquid from Nissan has the article number:

Top 5 analogues of original oil for Almera Classic manual transmission
Original oil Nissan is expensive (from 1,200 rubles per 1 liter), so many owners choose high-quality analogues. The main thing is that the product meets the specification API GL-4 and had a viscosity 75W-80 or 75W-90. Below are time-tested options:
- 🔧 Mobil Mobilube 1 SHC 75W-90 - synthetics with excellent low-temperature properties. Suitable for regions with frosts down to -30°C.
- 🔧 Castrol Syntrans Transaxle 75W-90 — semi-synthetic, optimal in terms of price/quality. Article:
157ABD. - 🔧 Liqui Moly Hochleistungs-Getriebeoil 75W-90 — German quality, protects against wear under high loads.
- 🔧 Motul Gear 300 75W-90 — ester oil for sport driving conditions. Expensive, but justifies itself on runs over 150 thousand km.
- 🔧 ZIC G-FF 75W-85 - a budget Korean option, suitable for moderate climates.
Important: do not use oils with API GL-5 classification! They contain aggressive additives that destroy manual transmission synchronizers Almera Classic. Also avoid generic oils like 80W-90 - they are too thick for this box, especially in winter.
Before purchasing oil, check its authenticity! Counterfeit transmission fluids are often sold in non-original cans with typos on the label. Pay attention to holograms and fonts.
Oil volume in Almera Classic manual transmission and how to check it
To a manual transmission Nissan Almera Classic (models with engines 1.6 And 1.4) is poured 2.8–3.0 liters of oil. The exact volume depends on the year of manufacture and modification:
- 📌 2006–2008 — 2.8 l (box
RS5F32V). - 📌 2009–2012 — 3.0 l (box
RS5F32Vwith a modified crankcase).
Check the oil level in the manual transmission Almera Classic possible through inspection hole, which is located on the box housing. To do this:
- Drive the car onto a pit or overpass.
- Clean the surface around the plug (to prevent dirt from getting inside).
- Unscrew the plug with the key to
24 mm. - The level should be at the bottom edge of the hole. If the oil is not visible, topping up is required.
⚠️ Attention! If, when checking the level, you find metal shavings or black sediment on the plug, this is a sign critical wear of gears or bearings. In this case, the oil needs to be urgently changed and the gearbox diagnosed!
What to do if the oil in the manual transmission turns black?
Blackening of the oil indicates its oxidation or the ingress of wear products. If the mileage after the last replacement is less than 30 thousand km, the reason may be counterfeit oil or overheating of the box. In both cases, a complete replacement with flushing is required.
Step-by-step instructions: how to change the oil in an Almera Classic manual transmission with your own hands
Changing the oil in manual transmission Almera Classic - The procedure is simple, but requires accuracy. You will need:
- 🔧 Key on
24 mm(for drain and filler plugs). - 🔧 Funnel with flexible hose (diameter ~10 mm).
- 🔧 Drain container (minimum 3 l).
- 🔧 New oil (3 l).
- 🔧 Gloves and rags.
Procedure:
Warm up the box (drive 5–10 km)|Drive the car into a pit/overpass|Prepare tools and oil|Put on gloves-->
- Draining old oil:
Unscrew the drain plug (bottom of the crankcase) and drain the oil into a container. Be careful - the liquid will be hot! Wait until it drains completely (10-15 minutes).
- Flushing (optional):
If the oil is very dirty, you can add 0.5 liters of new oil, tighten the plug, start the engine, engage 1st gear and let it run for 2-3 minutes. Then drain and refill with fresh water.
- Filling with new oil:
Screw in the drain plug. Pour new oil through the filler hole (upper part of the crankcase) until it begins to flow back out. Tighten the plug.
- Check:
Start the engine, drive 1–2 km and check the level. Top up if necessary.
Important: do not use sealant on the threads of plugs! In the crankcase Almera Classic Copper O-rings are provided to ensure a tight seal. If the ring is damaged, replace it.
After changing the oil, avoid sudden starts and overloads of the box for the first 100–200 km. This will help the new oil to be evenly distributed throughout all components.
Frequent mistakes when changing oil in Almera Classic manual transmission
Even experienced car owners sometimes make mistakes that can lead to box breakage. Here are the most common:
- ❌ Overfilling or underfilling oil:
Excess oil leads to foaming and loss of properties, and too little leads to oil starvation of the gears. Optimal level - along the bottom edge of the filler hole.
- ❌ Using automatic transmission oil:
Liquid type Nissan Matic Fluid D or
ATFincompatible with manual transmission! They have a different viscosity and additive package, which leads to synchronizer slipping. - ❌ Late replacement of O-rings:
Old rings on the plugs can allow oil to pass through, causing it to leak. They cost pennies (
11026-01M02- original article), but they forget to change them. - ❌ Changing the oil with a cold box:
Cold oil is thick and does not drain completely. Always warm up the box before replacing!
One more critical error - ignoring flushing the box when switching to another oil. For example, if you filled in mineral water and decided to switch to synthetics, the remnants of the old oil may react with the new one, forming a sediment. In this case it is required double replacement:
- Drain the old oil.
- Fill with flushing (or cheap mineral) oil.
- Drive 50–100 km.
- Drain the flushing oil and fill with new oil.
Signs that it’s time to change the oil in the Almera Classic manual transmission
If you haven't tracked your mileage or bought Almera Classic hands, pay attention to the following symptoms:
| Sign | Probable Cause | What to do |
|---|---|---|
| Crunching noise when shifting into 2nd or 3rd gear | Synchronizer wear due to old oil | Urgent oil change + transmission diagnostics |
| Difficulty shifting gears (especially when cold) | The oil has thickened or lost its properties | Changing oil to synthetic oil with the correct viscosity |
| Extraneous noises (howling, humming) when moving | Bearing wear due to lack of lubrication | Oil change + bearing check |
| Spontaneous speed loss | Critical wear of gears or shift fork | Overhaul of the box |
If you notice any of these signs, don't put off changing the oil. In some cases (for example, when speeding up), delay can lead to complete breakdown of the box, the repair of which will cost 30–50 thousand rubles.
To extend the life of the manual transmission, avoid holding the clutch for a long time at traffic lights (this increases the load on the release bearing) and do not engage gears with a “crunch” - it is better to double squeeze.
Answers to frequently asked questions about oil in the Almera Classic manual transmission
Is it possible to mix different oils in a manual transmission?
Mix oils not recommended, especially if they are from different manufacturers or with different bases (mineral water + synthetics). As a last resort, you can add something similar according to the classification (API GL-4) and viscosity (75W-80), but perform a complete replacement as soon as possible.
What happens if you fill in 80W-90 oil instead of 75W-80?
Oil 80W-90 thicker, so in winter the box will shift “tighter” before warming up. In summer there is almost no difference, but long-term use of such oil can accelerate the wear of synchronizers due to insufficient fluidity.
Is it necessary to flush the manual transmission when changing the oil?
Flushing is only necessary in two cases: if the oil is very dirty (black, with sediment) or if you change the type of oil (for example, from mineral water to synthetic). In other cases, it is enough to drain the old oil and fill in new oil.
How often do you check the oil level in a manual transmission?
Check the level every 10–15 thousand km or before long trips. Also be sure to check the level if you notice oil stains under the car in the box area.
Is it possible to fill oil through the breather rather than through the filler plug?
Technically it is possible, but it is inconvenient: the breather is located high, and the oil will flow slowly. In addition, there is a risk of overflow. It is better to use a filler hole with a funnel and hose.
