Nissan Almera Classic - one of the most popular foreign cars on the Russian secondary market, known for its reliability and unpretentiousness. However, even such an “indestructible” car has components that require regular maintenance. Manual transmission (Manual transmission) is exactly the element that is often left unattended until it begins to “signal” problems with creaking, difficult switching or leakage. Correct oil volume and its timely replacement is the key to a long transmission life.

In this article you will find exact data on oil volume for manual transmission Almera Classic (including modifications with 1.5 and 1.6 liter engines), recommendations for choosing lubricants, as well as step-by-step replacement instructions. We will also look at typical mistakes that owners make when servicing the box and give tips on how to avoid them. If you're planning to change the oil yourself, here's everything you need to know, from tools to the nuances of draining old fluid.

What kind of oil to fill in manual transmission Nissan Almera Classic?

Choosing oil for a manual transmission is not just a matter of brand, but technical necessity. Manufacturer Nissan recommends using gear oils that meet the standard API GL-4 or GL-5, with viscosity 75W-80 or 75W-90. Why these particular parameters?

The point is that Almera Classic (especially in the back B10) was equipped with gearboxes of the type RS5F31A (for 1.5 l engines) and RS5F32A (for 1.6 l). These units are sensitive to the quality of the lubricant: oil that is too thick in winter will make it difficult to shift gears, and oil that is too thin will not provide adequate protection for the gears under high loads. The best option is synthetics or semi-synthetics with the above characteristics.

  • 🔹 Original oil: Nissan MT-XZ Fluid (article KE908-99932) is an ideal choice, but expensive.
  • 🔹 Analogues: Mobil Mobilube 1 SHC 75W-90, Castrol Syntrans Transaxle 75W-90, Liqui Moly Hochleistungs-Getriebeoil 75W-90.
  • 🔹 Budget option: ZIC G-FF 75W-85 (suitable for temperate climates).
  • 🔹 What to avoid: oils with markings GL-5+ or MT-1 - they contain aggressive additives that can damage synchronizers.
⚠️ Attention: If you operate your car in regions with frosts below -30°C, give preference to oil with a viscosity 70W-80. It remains fluid at extremely low temperatures, but requires more frequent replacement (every 60 thousand km).

Table: oil volume in manual transmission Nissan Almera Classic by model

The amount of oil in the gearbox depends on the type of transmission and the year of manufacture of the car. Below is a table with exact data for the most common modifications Almera Classic (including restyled versions). Please note: values are for complete replacement (with draining of old oil and flushing).

Model/Engine Manual transmission type Oil volume, l Recommended viscosity
Almera Classic B10 (2006–2012), 1.5 L (K4M) RS5F31A 2.8–3.0 75W-80 / 75W-90
Almera Classic N16 (2012–2018), 1.6 l (HR16DE) RS5F32A 2.5–2.7 75W-80
Almera Classic (restyling 2015+), 1.6 l RS5F32A (modified) 2.6 75W-90
Almera Classic with power steering (all engines) RS5F31A / RS5F32A +0.1 l to base volume 75W-80

Important: If you are unsure of the exact type of box you have, check the label on the case (usually located on the top or side). Also note that when partial replacement (without flushing) 0.3–0.5 liters less oil will be required, since some of the old fluid remains in the unit.

How to check the oil level in a manual transmission?

Unlike automatic transmissions, manual transmissions Nissan Almera Classic They do not have a dipstick to check the oil level. This means that control is carried out through filler pluglocated on the body of the box. The procedure is simple, but requires care:

  1. Place the car on flat surface (lift or inspection hole).
  2. Clean the area around the filler plug of dirt (to prevent debris from getting inside).
  3. Unscrew the plug with the key to 24 mm.
  4. The oil level should be at the level of the bottom edge of the hole. If it is lower, topping up is required.
  5. If the oil is not visible at all, urgently add it and check the box for leaks.

Please note: it is better to check on warm box (after 10–15 km of driving), since cold oil may give inaccurate readings. If oil starts to flow out when you unscrew the plug, the level is normal.

⚠️ Attention: Do not confuse the filler plug with drain! The drain plug is located at the bottom and usually has a magnet to collect metal shavings. Unscrewing it without preparation will lead to complete drainage of the oil.
💡

If you are not sure about the purity of the oil, drop it on a white paper napkin. The presence of dark particles or metal dust is a signal for replacement, even if the level is normal.

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 with a minimum set of tools. The main thing is to maintain consistency and not skimp on consumables. Below are detailed instructions taking into account the nuances for different modifications.

Warm up the box (drive 10–15 km)|Prepare a container for drainage (at least 3 l)|Buy new oil with a reserve (3–3.5 l)|Prepare 24 mm and 10 mm wrenches|Stock a new sealing washer for the drain plug-->

Step 1. Drain the old oil

  1. Drive the car onto a pit or lift. Make sure it is completely horizontal.
  2. Remove the crankcase protection (if equipped) using the wrench on 10 mm.
  3. Place a container under the drain plug (it is located at the bottom of the box).
  4. Carefully unscrew the plug using the key 24 mm. Be prepared for the oil to start leaking out under pressure.
  5. Wait until it drains completely (usually takes 10–15 minutes). Assess the condition of the oil: if it is black or has metal particles, the box needs diagnostics.

Step 2: Flushing (optional)

If the oil is very dirty or you do not know when it was last changed, flushing is recommended. To do this:

  1. Screw in the drain plug.
  2. Fill through the filler hole 1–1.5 l of flushing oil (For example, Liqui Moly Getriebe-Reiniger).
  3. Start the engine and let the transmission run for 5-10 minutes in neutral gear.
  4. Drain the flushing fluid and start filling in new oil.

Step 3. Filling with new oil

Use a funnel with a flexible hose or a special syringe for transmission oils. Algorithm:

  1. Screw in the drain plug with a new sealing washer (copper or aluminum).
  2. Slowly pour new oil through the filler hole until it begins to flow back out.
  3. Screw in the filler plug. Make sure the O-ring is intact.
  4. Drive 5–10 km and recheck the level.
💡

Do not overfill the oil! Excessive levels cause the fluid to foam, which impairs gear lubrication and can cause seal leaks.

Typical mistakes when changing oil in a manual transmission

Even experienced car owners sometimes make mistakes that can lead to serious problems with the gearbox. Here are the most common of them:

  • 🚫 Using oil of the wrong viscosity. For example, fill 80W-90 instead of 75W-80 will lead to difficult gear shifting in winter.
  • 🚫 Failure to comply with replacement intervals. The manufacturer recommends changing the oil every 90–100 thousand km, but in Russian conditions (dust, temperature changes) it is better to reduce the interval to 60–70 thousand km.
  • 🚫 Ignores metal shavings. If a lot of particles have accumulated on the drain plug magnet, this is a sign of wear on the synchronizers or bearings. Diagnostics required!
  • 🚫 Filling oil without flushing when the old fluid is heavily contaminated. This is equivalent to mixing dirty and clean oil.
  • 🚫 Pulling traffic jams. Excessive tightening force may damage the threads or deform the seal.

Another common mistake is use of sealant on the threads of the plugs. This is unacceptable: the sealant can get inside the box and clog the channels. Use instead new sealing washers (copper or aluminum).

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

Long-term operation with old oil leads to:

- Accelerated wear of synchronizers (crunching and difficult gear shifting will appear).

- Corrosion of gears due to the accumulation of moisture and oxidation products.

- Damage to bearings (manifested by hum or vibration in neutral gear).

- In critical cases - jamming of the box. Repairs will cost 30–50 thousand rubles, while an oil change costs 1–2 thousand rubles.

When is an unscheduled oil change required?

In addition to the regulatory intervals, there are situations when the oil in the manual transmission Almera Classic needs to be replaced ahead of schedule. Ignoring these signs can lead to costly repairs:

  • 🔧 After purchasing a used car. You don’t know what kind of oil the previous owner filled in and when he changed it.
  • 🔧 After repairing the box. For example, after replacing the clutch or seals, a foreign substance (dust, fibers from gaskets) could get into the box.
  • 🔧 When a leak is detected. If the oil level drops for no apparent reason, look for leaks around the seals or gaskets.
  • 🔧 After driving through deep puddles or in very dusty conditions. Water and abrasive particles reduce oil life.
  • 🔧 When extraneous noise appears. A hum, grinding or crunching sound when switching is a reason to check the condition of the oil and gearbox.

If you notice that the oil in the box has become cloudy or has burnt smell, this is a sign of overheating or severe wear of parts. In this case, a regular oil change may not be enough; diagnostics by a specialist will be required.

Answers to frequently asked questions (FAQ)

Is it possible to mix different oils in a manual transmission? Almera Classic?

Mix oils of different manufacturers or viscosities not recommended, as this may lead to a chemical reaction of the additives and loss of lubricity. An exception is adding a small amount (up to 10% of the volume) of oil of the same type and viscosity in emergency cases. Perform a complete replacement as soon as possible.

What to do if the gears are difficult to engage after changing the oil?

This can be caused by several reasons:

  1. Oil filled unsuitable viscosity (too thick).
  2. Left in the box air (you need to drive 10–20 km and check the level again).
  3. Faulty synchronizers or shift forks (diagnostics required).

If the problem does not disappear after 100–200 km, contact service.

How often should you check the oil level in a manual transmission?

The manufacturer does not set strict deadlines, but it is optimal to check the level every 10–15 thousand km or before long trips. This is especially true for cars with a mileage of more than 150 thousand km, when the risk of leakage through the seals increases.

Is it possible to use automatic transmission oil in a manual transmission? Almera Classic?

Absolutely not! Oils for automatic and manual transmissions have different compositions and properties. Automatic transmission fluid (for example, ATF) will not provide adequate protection for the gears and synchronizers of the manual transmission, which will lead to their accelerated wear.

What tools are needed to change the oil yourself?

Minimum set:

  • Key on 24 mm (for drain and filler plugs).
  • Key on 10 mm (to remove crankcase protection).
  • Container for draining (volume of at least 3 l).
  • A funnel with a flexible hose or a syringe for pouring.
  • New sealing washers for plugs (copper or aluminum).
  • Rags and gloves.
