Crossover Nissan X-Trail second generation (body T31, 2007–2013) remains a popular choice among owners due to its reliability and unpretentiousness. However, even such a proven car requires competent maintenance - especially when it comes to changing engine oil. Errors here can lead to accelerated engine wear, overheating, or even turbine breakdown (if there is one).

In this article you will find Accurate oil volume data for all X-Trail T31 engines, including QR25DE (2.5 l), MR20DE (2.0 l) and diesel options. We will also look at what kind of oil to use (synthetic or semi-synthetic), how often to change it depending on operating conditions, and why “overfilling” is just as dangerous as “underfilling”. If you are planning a replacement yourself, here are step-by-step instructions with nuances for T31.

Technical characteristics of X-Trail T31 engines: how much oil is needed

Cars Nissan X-Trail T31 equipped with three main types of engines: gasoline QR25DE (2.5 l), MR20DE (2.0 l) and diesel M9R (2.0 l). The oil volume for each of them is different - and these are not just numbers from the manual, but a critical parameter that affects the lubrication and cooling of parts.

Important: the data in the table below is valid for complete oil change with filter replacement. If you drain the oil without flushing or use the vacuum method, the volume may differ by 100–200 ml.

Engine model Oil volume (l) Oil type (viscosity) Features
QR25DE (2.5 l, petrol) 4.4–4.6 5W-30, 5W-40 Sensitive to oil quality; overfilling may cause leaks through the seals
MR20DE (2.0 l, petrol) 4.3–4.5 5W-30, 0W-30 Less demanding, but with mileage >150 thousand km, 5W-40 is recommended
M9R (2.0 l, diesel) 5.4–5.6 5W-30 (Low SAPS) Requires approved oil RN0700, otherwise there is a risk of the diesel particulate filter becoming clogged

⚠️ Attention: For diesel M9R use of oil without approval RN0700 or RN0710 leads to failure of the particulate filter (DPF) already after 30–50 thousand km. This is not a warranty case!

If you are not sure about the engine type, check it by VIN number or find the marking on the cylinder block (front, under the hood). For example, QR25DE will be designated as QR25DE XXXX, where XXXX - serial number.

What oil to pour into X-Trail T31: viscosity, brands and tolerances

Choosing oil for Nissan X-Trail T31 depends not only on the type of engine, but also on climatic conditions, mileage and driving style. The manufacturer recommends adherence to standards API SN (for gasoline) and ACEA C3/C4 (for diesel engines), but there are nuances.

For gasoline engines (QR25DE, MR20DE):

  • 🔹 5W-30 — the optimal choice for most regions of Russia (from –30°C to +35°C). Suitable for new and moderately worn engines.
  • 🔹 5W-40 - preferable for cars with mileage >100 thousand km or with aggressive driving. Better protects against wear under high loads.
  • 🔹 0W-30 — relevant for northern regions (below –35°C), but requires frequent replacement (every 7–8 thousand km).

For diesel M9R:

  • 🔹 5W-30 Low SAPS - a prerequisite for maintaining the particulate filter. Oils high in sulfur and phosphorus (SAPS) destroy DPF.
  • 🔹 Tolerances: RN0700 (for petrol versions with catalyst) or RN0710 (for diesel engines).

Recommended brands (based on reviews from owners and service centers):

  • 🏆 Mobil 1 ESP 5W-30 — universal choice for gasoline and diesel, compatible RN0700.
  • 🏆 Motul Specific DEXOS2 5W-30 - suitable for MR20DE with mileage.
  • 🏆 Liqui Moly Top Tec 4200 5W-30 - optimal for diesel engines M9R.
  • 💰 Nissan Strong Save X 5W-30 — original oil, but more expensive than analogues.
💡

If you live in a region with sudden temperature changes (for example, -25°C in winter and +30°C in summer), use oil with the index 5W-40 all year round. It flows worse in the cold than 5W-30, but protects more reliably in the summer.

When to change the oil in the X-Trail T31: regulations and real terms

Official regulations Nissan requires oil changes every 15,000 km or once a year, whichever comes first. However, these figures are relevant for “ideal” conditions: moderate climate, high-quality fuel and a quiet ride. In reality, the intervals should be shortened:

  • 🚗 10,000 km — for gasoline engines during urban use (frequent traffic jams, short trips).
  • 🚜 7,000–8,000 km - for diesel M9R or when using low quality fuel.
  • ❄️ 5,000–6,000 km — if the car is operated in extreme conditions (severe frost, dusty roads, towing a trailer).

⚠️ Attention: Diesel engines M9R extremely sensitive to oil aging. If replacement is ignored, the oil viscosity increases, which leads to clogging of the oil passages and rotation of the liners (repairs will cost 150+ thousand rubles).

How to understand when it's time to change the oil ahead of schedule:

  • 🔍 The oil on the dipstick has become dark and thick (even if the mileage is less than 10 thousand km).
  • 🔊 The engine runs louder than usual when cold.
  • 💨 Blue smoke comes from the exhaust pipe (especially relevant for diesel engines).
  • 📉 Fuel consumption has increased for no apparent reason.

Step-by-step instructions: how to change the oil in the X-Trail T31 yourself

Changing the oil in Nissan X-Trail T31 - a procedure that even a beginner can handle if you follow the instructions. You will need:

  • 🛠️ New oil (see the table above for volume).
  • 🔧 Oil filter (original art. 15208-9F600 for gasoline, 15208-ED00A for diesel).
  • 🔩 14 mm wrench (for drain plug).
  • 🧰 Oil filter puller (or belt/chain).
  • 📦 Capacity for working out (minimum 5 l).
  • 🧻 Rags and gloves.

Step 1: Warm up the engine

Start the car and let it run for 3-5 minutes. Warm oil drains faster and more completely. But do not overheat - the oil temperature should be ~50–60°C (to avoid getting burned).

Step 2: Drain the old oil

  1. Lift the car on a lift or drive it into a pit.
  2. Unscrew the drain plug (14 mm wrench) - it is located at the bottom of the pan.
  3. Place the container and wait until the oil drains (10–15 minutes).

Step 3: Replace the oil filter

The filter is located to the right of the engine (when viewed in the direction of travel). Unscrew it with a puller, lubricate the rubber ring of the new filter with fresh oil and install it in place. Screw by hand - don’t overtighten!

Step 4: Fill with new oil

  1. Tighten the drain plug (tightening torque: 35–40 Nm).
  2. Fill ~80% of the required volume of oil through the filler neck.
  3. Start the engine, let it run for 1-2 minutes, then turn it off.
  4. Check the level on the dipstick and add to the mark MAX.
What happens if you overfill the oil?

Overfilling the oil (>500 ml from the norm) leads to foaming and loss of lubricating properties. B QR25DE this is fraught with leakage through the crankshaft oil seal, and in M9R - increased pressure in the system and squeezing out gaskets. If you overfilled, drain the excess through the drain plug.

Common mistakes when changing oil and how to avoid them

Even experienced car owners sometimes make mistakes that reduce engine life. Here are the most common ones for X-Trail T31:

  1. Using the wrong oil

    For example, fill 10W-40 instead of 5W-30 worsens cold starts and increases wear. For diesels M9R using oil without Low SAPS leads to clogging of the particulate filter.

  2. Underfilling or overfilling of oil

    Underfilling by 0.5–1 liters impairs lubrication, and overfilling (>300 ml) creates excess pressure. IN QR25DE this often causes the crankshaft rear seal to leak.

  3. Saving on oil filter

    Cheap filters (for example, without a check valve) do not retain oil in the system after the engine is stopped. This leads to oil starvation at startup.

  4. Ignoring flushing when changing oil type

    If you are switching from semi-synthetic to synthetic or changing viscosity (for example, from 5W-30 on 5W-40), the engine must be flushed with a special liquid (Liqui Moly Oil-Schlamm-Spulung).

⚠️ Attention: In diesel X-Trail T31 with particulate filter (DPF) do not use flushing oils or additives! They contain aggressive components that destroy the catalyst.

💡

The most dangerous mistake is ignoring oil tolerances for diesel engines. M9R. Unlabeled oil RN0700 or RN0710 leads to failure of the particulate filter (DPF) and turbines.

How to check the oil level in X-Trail T31: nuances

Checking the oil level seems like a simple procedure, but even here there are pitfalls. For X-Trail T31 The following rules apply:

  1. Test on a flat surface

    If the car is parked on a slope, the dipstick readings will be inaccurate.

  2. The engine should be warm but turned off

    It is optimal to check 5–10 minutes after stopping the engine. If you check “cold”, the level will be underestimated.

  3. Wipe the dipstick before checking

    Remaining oil on the dipstick distorts the result. Use clean rags.

  4. The level should be between MIN And MAX

    Ideal - closer to MAX, but not higher. B QR25DE An overflow of 0.3–0.5 liters is already critical.

If the oil level drops faster than usual (for example, you have to add >1 liter per 5 thousand km), this is a sign:

  • 🔧 Wear of piston rings or oil seals.
  • 🔥 Leaks through the valve cover gasket or seals.
  • 💨 Problems with the turbine (relevant for diesel engines M9R).

In such cases, diagnosis is required. For X-Trail T31 normal oil consumption - up to 300 ml per 10,000 km.

FAQ: answers to frequently asked questions about oil in X-Trail T31

Can I use 10W-40 oil instead of 5W-30 in a petrol X-Trail T31?

Technically possible, but not recommended. Oil 10W-40 thicker when cold, which impairs engine starting in winter and increases wear. The exception is cars with mileage >200 thousand km, where the gaps in the friction pairs are increased.

How much oil should I pour if I don't change the filter?

When replacing without a filter, 0.2–0.3 liters less is required (see table above). However, it is not recommended to do this - ~100–150 ml of dirty oil remains in the old filter, which will mix with the new one.

What kind of oil is poured into the new X-Trail T31 from the factory?

From the factory, gasoline engines were filled with Nissan Strong Save X 5W-30 (art. KE900-90132). In diesel - Total Quartz INEO ECS 5W-30 (tolerance RN0700). However, after 100 thousand km it is better to switch to oil with a higher viscosity (for example, 5W-40).

What happens if you don’t change the oil for more than 20 thousand km?

For gasoline engines (QR25DE, MR20DE) this is fraught with:

  • Formation of sludge in oil channels.
  • Increased fuel consumption by 10–15%.
  • Wear of the turbine (if any) and main bearings.

For diesels M9R the consequences are more serious: the particulate filter becomes clogged (DPF), fails EGR, the piston rings may be stuck.

Is it possible to mix oils from different brands?

Mix oils you canif they:

  • Have the same viscosity (for example, both 5W-30).
  • Meet the same standards (API SN, ACEA C3 etc.).
  • They are synthetic or semi-synthetic (do not mix with mineral ones!).

However, it is better to avoid mixing - make a complete replacement as soon as possible.
