Owners Nissan Almera N16 With a manual transmission, people are often faced with the question: what kind of oil should be poured into the manual transmission in order to extend the life of the unit and avoid costly repairs? This model, released in 2000–2006, was equipped with two types of manual transmissions - RS5F31A (for 1.5/1.6 l engines) and FS5R30A (for 1.8 l), each of which requires a specific approach to maintenance.

The manufacturer specifies strict requirements for viscosity and oil standards, but in practice, owners are faced with a shortage of original fluids and the need to choose among analogues. In this article we will look at official Nissan recommendations, let's analyze compatible analogues from Mobil, Castrol, Liqui Moly and other brands, and also reveal the nuances of changing the oil that even experienced technicians ignore. We will pay special attention critical errors during replacement, which can damage the gearbox within 10–15 thousand km.

Official Nissan requirements for oil for the Almera N16 manual transmission

According to service documentation Nissan, for mechanical boxes Almera N16 It is prescribed to use gear oils with the following characteristics:

  • 🔹 SAE Viscosity: 75W-80 or 75W-90 (depending on climatic conditions).
  • 🔹 Quality standard: API GL-4 (for RS5F31A) or API GL-4/GL-5 (for FS5R30A).
  • 🔹 Original oil: Nissan MT-XZ Gear Oil (art. KE908-99932) or its analogue Nissan Matic S (for some markets).
  • 🔹 Refill volume: 2.3–2.5 l (the exact volume depends on the type of box and replacement method).

Important: Nissan does not recommend using oils with grade GL-5 for box RS5F31A, since they contain aggressive additives that destroy synchronizers made of non-ferrous metals. The exception is the box FS5R30A, where allowed GL-4/GL-5, but with reservations.

⚠️ Attention: The manuals for the European market indicate API GL-4, and for Asian - GL-4/GL-5. This is due to differences in synchronizer materials. Usage GL-5 in RS5F31A leads to accelerated wear of 2nd and 3rd gears.

Top 5 oils for manual transmission Almera N16: original vs analogues

Original oil Nissan MT-XZ difficult to find in retail, and often overpriced. Below are proven analogues that meet the manufacturer’s requirements:

Brand and name Viscosity Standard Article Notes
Nissan MT-XZ Gear Oil 75W-80 API GL-4 KE908-99932 Official recommendation, ideal for RS5F31A.
Mobil Mobilube 1 SHC 75W-90 75W-90 API GL-4/GL-5 152660 Suitable for FS5R30A, but undesirable for RS5F31A.

Oil change intervals: when and why is it critical?

The manufacturer claims that the oil in the manual transmission Almera N16 filled for the entire service life, but in practice this is not the case. Real operating conditions (city traffic jams, aggressive driving, climate) reduce oil life by 2–3 times.

Recommended replacement intervals:

  • 🔧 60–80 thousand km - for oils API GL-4 (optimal interval for most regions).
  • 🔧 40–50 thousand km — when used in difficult conditions (taxi, frequent towing, off-road).
  • 🔧 100 thousand km — maximum permissible mileage for synthetic oils GL-4/GL-5, but with the risk of wear of the synchronizers.
⚠️ Attention: If there is a crunch or a hard shift when shifting gears, the oil needs to be changed. immediately - This is a sign of additive degradation. In 80% of cases, delay leads to damage to the 2nd and 3rd gear synchronizers.

How can you determine when it’s time to change the oil without measuring mileage?

  • 🔍 Darkening of the oil (light amber → dark brown).
  • 🔍 Metal shavings appear on the magnet of the drain plug.
  • 🔍 Increased gearbox noise in neutral gear.
💡

Before changing the oil, warm up the box to operating temperature (10–15 km). This will reduce the viscosity of the oil and allow you to drain up to 90% of the waste instead of the standard 70%.

Step-by-step instructions for changing the oil in the Almera N16 manual transmission

Changing the oil in a manual transmission Almera N16 does not require special equipment, but has a number of nuances. You will need:

  • 🔧 Key on 24 mm (for drain plug).
  • 🔧 Key on 17 mm (for filler plug).
  • 🔧 Oil syringe (or funnel with flexible tube).
  • 🔧 New oil (2.5–3 l including flushing).
  • 🔧 New sealing washer for the drain plug (11026-01M02).

Replacement algorithm:

  1. Place the car on a viewing hole or lift. The box must be horizontal for complete drainage.
  2. Remove the crankcase protection (if installed).
  3. Clean the drain plug from dirt and unscrew it with a wrench 24 mm. Be careful - the oil is hot!
  4. Wait until the oil is completely drained (15–20 minutes). Inspect the plug magnet for chips.
  5. Screw on the drain plug with a new washer. Tightening torque - 35–40 Nm.
  6. Unscrew the filler plug (key on 17 mm, located above the drain).
  7. Fill in new oil with a syringe to the level of the lower edge of the filler hole.
  8. Tighten the filler plug and check the level after 5–10 km.

A critical mistake of many owners - underfilling or overfilling of oil:

  • 🚫 Underfilling leads to oil starvation of bearings and accelerated wear.
  • 🚫 Overflow increases pressure in the box, squeezing out the seals and leading to leaks.

Common mistakes when choosing and changing oil

Even experienced car owners make mistakes that reduce the life of a manual transmission. Almera N16. Here are the most common:

  1. Use of oil GL-5 in a box RS5F31A — destroys brass synchronizers. Symptoms: crunching noise when shifting into 2nd and 3rd gears.
  2. Oil change without flushing in case of heavy contamination. Old oil leaves deposits that mix with new oil and reduce its properties.
  3. Ignoring the magnet on the drain plug. If chips have accumulated on it, they must be removed and the plug cleaned.
  4. Application of universal oils GL-4/GL-5 excluding box type. For example, Liqui Moly 75W-90 suitable for FS5R30A, but not for RS5F31A.
  5. Tightening plugs without a torque wrench. Excessive torque (>40 Nm) leads to thread failure in the aluminum crankcase.
What happens if you mix oils from different brands?

Mixing oils GL-4 And GL-5 (even of the same viscosity) leads to a chemical reaction of the additives, which results in the formation of flakes and sediment. This clogs the lubrication channels and accelerates bearing wear. In critical cases, the box may “stand up” after 5–10 thousand km. If you had to add another oil, a complete replacement with flushing after 1–2 thousand km is recommended.

Another typical problem is counterfeit oils. Up to 30% of gear oils on the market are counterfeit. How to distinguish the original:

  • 🔍 Check the label: Nissan MT-XZ hologram with a changing pattern when tilted.
  • 🔍 The canister must have a bottling date (on the bottom or neck).
  • 🔍 Lower price 800–1000 rub./l - a reason for suspicion.

Signs of manual transmission malfunction related to oil

If the oil is in the box Almera N16 does not meet the requirements or has not been changed for a long time, characteristic symptoms appear:

Symptom Probable Cause Consequences
Crunching sound when shifting to 2nd gear Degradation of additives in oil or use GL-5 Worn synchronizers requiring box repair
Difficulty shifting gears when cold Thickened oil (incorrect viscosity or older than 80 thousand km) Increased load on forks and gears
Noise (howl) in neutral gear Oil starvation of bearings Destruction of shaft bearings, metal shavings in oil
Oil leaking from seals Increased pressure due to overflow or foam in the oil Drop in oil level, risk of box jamming

If you notice any of these symptoms, do not delay diagnosis. For example, a crunch when switching to 2nd gear at a mileage of 100+ thousand km in 90% of cases means wear of the synchronizer, which will require replacement after 10–20 thousand km.

💡

Use of oil API GL-4 with viscosity 75W-80 - the best choice for most Almera N16 with box RS5F31A. It provides easy switching to cold and protection of synchronizers.

Answers to frequently asked questions (FAQ)

Is it possible to use oil 75W-140 for hot climates?

No. Boxes Almera N16 not designed for such viscosity. Oil 75W-140 will create excess resistance at low temperatures and accelerate wear of the synchronizers. The best choice for hot climates is 75W-90 with a package of additives for high temperatures (for example, Castrol Syntrans Transaxle).

What to do if there is noise in the gearbox after changing the oil?

Noise after oil change may be caused by:

  1. Insufficient oil level (add to the lower edge of the filler hole).
  2. Using oil with an unsuitable viscosity (for example, 80W-90 instead of 75W-90).
  3. Air entering the system (you need to flush out the oil by shifting gears with the engine off).
  4. Bearing wear, which became noticeable after an oil change (diagnostics required).

If the noise does not disappear after checking the level and a short run-in (50–100 km), contact a specialist.

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

Flushing is required in three cases:

  • When switching from one type of oil to another (for example, from GL-4 on GL-5).
  • If metal shavings are visible in the drained oil or it has a burning smell.
  • If the mileage on old oil exceeds 100 thousand km.

For flushing, use special flushing oil (for example, Liqui Moly Getriebe-Reiniger) or fresh transmission oil, which is poured in for 5–10 minutes of operation of the box, and then drained.

What kind of oil is poured into the Almera N16 manual transmission from the factory?

From factory to box Almera N16 poured:

  • RS5F31A (1.5/1.6 l) — Nissan MT-XZ 75W-80 (API GL-4).
  • FS5R30A (1.8 l) — Nissan Matic S 75W-90 (API GL-4/GL-5).

However, after 15–20 years of operation, factory oil loses its properties, and its replacement becomes mandatory.

Is it possible to pour motor oil into a manual transmission in emergency cases?

Absolutely not. Motor oils do not contain additives necessary to protect synchronizers and gearbox gears. Even short-term use of motor oil (e.g. 5W-40) leads to:

  • Accelerated wear of bearings.
  • Synchronizers jamming due to lack of anti-wear additives.
  • Foaming and loss of lubricating properties.

If topping up is urgently required, use only transmission oil of the same type that is already poured into the box.
