Nissan Almera G15 - a popular sedan with a manual transmission, which is famous for its reliability. However, even the most durable manual transmission requires maintenance, and the key point here is the right oil. Many owners mistakenly believe that transmission fluid in mechanics is “eternal” and does not need to be replaced. This is a myth: over time, oil loses its properties, which leads to accelerated wear of gears and bearings.

In this article we will look at what kind of oil is poured into the manual transmission Almera G15 from the factory, which analogues are suitable for replacement, how often to carry it out and how to do everything yourself. You will also find an oil compatibility table, warnings about common errors and answers to frequently asked questions.

Original oil in the Nissan Almera G15 manual transmission: what was filled in from the factory?

From factory to manual transmission Nissan Almera G15 (models 2013–2019) filled gear oil Nissan MT-XZ Gear Oil 75W-80. This is a synthetic fluid that meets the standard API GL-4. It is optimized to work with synchronizers and gearbox bearings, ensuring smooth gear shifting even at low temperatures.

Important: original oil MT-XZ is not “lifetime”. In the instruction manual Almera G15 indicated that replacement is required every 90–120 thousand km (or once every 5–7 years with gentle operation). However, in the conditions of Russian roads and climate, it is better to reduce this interval to 60–80 thousand km - especially if the car often drives in traffic jams or in cold weather.

  • 🔧 Article number of the original oil: KE916-99932 (1 l canister) or KE916-99931 (4 l).
  • 🔍 Specification: API GL-4, viscosity 75W-80.
  • ⚠️ Not compatible with oils GL-5 — they are aggressive towards synchronizers!
⚠️ Attention: If you buy original oil Nissan MT-XZ, check the packaging for the presence of a hologram and production date. Counterfeits are often found in online stores with suspiciously low prices.

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

Original oil is not always available or its price seems overpriced. Fortunately, there are worthy analogues from trusted brands. The main thing is to comply viscosity 75W-80 and standard API GL-4.

Here are the tested options:

Brand and name Article Viscosity Standard Notes
Mobil Mobilube 1 SHC 75W-80 152644 75W-80 API GL-4/GL-5 Suitable for cold climates, but contains GL-5 - do not overdo the replacement frequency.
Castrol Syntrans Transaxle 75W-90 15669A 75W-90 API GL-4+ Thicker than the original, but protects well under high loads.
Liqui Moly Hochleistungs-Getriebeoil 75W-80 3941 75W-80 API GL-4/GL-5 Optimal price/quality balance, often recommended by craftsmen.
Motul Gear 300 75W-80 105777 75W-80 API GL-4 The best choice for aggressive riding is high thermal stability.

If you choose between 75W-80 And 75W-90, give preference to the first option - it is better suited for Almera G15 with its synchronizers. Oils with index GL-5 acceptable, but only if they are certified and under GL-4 (like Liqui Moly or Mobil).

Oil volume in manual transmission Nissan Almera G15: how much to fill?

Oil volume in manual transmission Almera G15 depends on the type of gearbox. Two modifications were installed on this model:

  • 🔄 JR5 (5-speed manual transmission) - the most common version. Refill volume: 2.8–3.0 l.
  • 🔄 JH3 (5-speed manual transmission in some markets) - less common. Refill volume: 2.5–2.7 l.

To accurately determine the type of box, look at the nameplate under the hood or check the VIN code through the service official Nissan decoder. When changing oil, it is recommended to buy 3.5 l - this is enough for a complete replacement with flushing.

⚠️ Attention: Do not add oil by eye! Overfilling is just as harmful as underfilling: excess pressure can squeeze out the seals, and too little will lead to oil starvation of the gears.
💡

Always drain the oil after a trip when the box is warm - this way it will drain out as completely as possible.

When to change the oil in the Almera G15 manual transmission: signs and frequency

Official regulations Nissan prescribes the first oil change in a manual transmission to 90,000 km, but this is an optimistic scenario. Real operating conditions dictate other rules:

  • 🚗 City mode (frequent traffic jams, short trips) - replacement every 60,000 km.
  • ❄️ Extreme temperatures (frost below -30°C or heat above +35°C) - reduce the interval to 50,000 km.
  • 🏁 Aggressive riding (sharp starts, towing a trailer) - check the condition of the oil every 40,000 km.

How do you know when it’s time to change the oil, even if the mileage has not reached the specified mileage?

  • 🔊 Crunching or grinding noise when changing gears (especially when cold).
  • 🖐️ Tight inclusion first or second gear.
  • 🩹 Oil leaks on the box housing or near the seals.
  • 🟤 Dark oil color (on the dipstick or when draining) and a burning smell.
💡

If you bought Almera G15 with mileage and don’t know when the oil in the manual transmission was last changed, replace it immediately - it’s cheaper than repairing the transmission.

Step-by-step instructions: how to change the oil in an Almera G15 manual transmission yourself

Changing the oil in a manual transmission Almera G15 - The procedure is simple, but requires accuracy. You will need:

  • 🔧 Key for 10 (for drain plug).
  • 🔧 Key for 24 (for filler plug).
  • 🛢️ Funnel and hose (~8 mm in diameter).
  • 🧤 Gloves and rags.
  • 🚗 Pit, overpass or lift.

If you don’t have an inspection hole, you can get by with a jack, but this is less convenient and safe.

Warm up the box (drive 5–10 km)|Drive the car into the pit and lock the handbrake|Prepare a container for draining (at least 3 liters)|Wear gloves - the oil will be hot|Check for a new sealing washer for the drain plug-->

Step 1: Drain the old oil

1. Unscrew drain plug (lower plug on the gearbox housing) with a 10 key. Be careful - the oil will be hot!

2. Wait until it drains completely (about 10–15 minutes). If the oil is dark with metal shavings, this is a signal of increased wear.

3. Wipe the plug and magnet (if any) from dirt. Replace the sealing washer.

Step 2: Flushing (optional)

If the oil is very dirty, you can wash the box. To do this:

1. Fill 0.5–1 l new oil.

2. Start the engine, engage first gear and let it run for 2-3 minutes.

3. Drain the flushing oil and start filling in new oil.

⚠️ Attention: Do not use aggressive “5-minute” washes - they can damage the seals and synchronizers!

Step 3: Add new oil

1. Unscrew filler plug (located above the drain, closer to the motor).

2. Insert the hose with funnel and slowly fill in the oil. Check the level - it should reach the bottom edge of the filler hole.

3. Screw the plug with a new seal. Tightening torque: 30–40 Nm.

Check the operation of the box: shifts should be smooth, without crunching. If strange sounds appear, the oil may not be suitable or its level is incorrect.

What to do if you overfilled the oil?

If the oil level is higher than normal, it needs to be drained. To do this:

1. Unscrew the drain plug and drain the excess (it will flow out first).

2. Tighten the plug and check the level through the filler hole.

3. If oil continues to flow out after tightening the plug, replace the sealing washer.

Typical mistakes when changing oil in Almera G15 manual transmission

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

  • 🛑 Use of oil GL-5 instead of GL-4 - this will accelerate the wear of the synchronizers.
  • 🛑 Savings on sealing washers - An old washer may leak oil.
  • 🛑 Unheated box before draining — cold oil does not drain completely.
  • 🛑 Filling oil through the breather (not through the filler hole) - this can lead to dirt getting in.
  • 🛑 Ignoring leaks after replacement — if oil oozes, you need to urgently eliminate the cause.

Another common mistake is incorrect tightening torque. Too little tightening will lead to leakage, and too much will lead to thread breakage. Use a torque wrench!
