<em>Nissan X-Trail T31</em>(2007–2013) Fuel Capacities: A Complete Guide to Fluids and Fuel

Nissan X-Trail T31 is one of the most popular crossovers on the Russian market, combining reliability, cross-country ability and comfort. Owners of this model are often faced with the question: what fluids and in what quantity should be filled during maintenance? Not only the service life of the engine and transmission, but also safety on the road depends on the correct refueling volumes.

In this article we have collected manufacturer's official data for all fluids - from engine oil to brake fluid, and also took into account the nuances for different types of engines (MR20DE, QR25DE, diesel M9R And YD25DDTi). We paid special attention difference in volumes for models with all-wheel drive and front-wheel drive, as well as options with a variator Jatco and manual transmission.

If you are planning independent maintenance or simply want to control the operation of the service, this information will be useful. We've also included practical tips, warnings about common mistakes, and answers to frequently asked questions.

1. Engine oil: volumes and recommendations for Nissan X-Trail T31

Engine oil volume X-Trail T31 depends on the type of power unit and operating conditions. The manufacturer recommends using oils of the class API SL/SM or ILSAC GF-4 with viscosity 5W-30 or 5W-40 for gasoline engines. For diesel engines (M9R, YD25DDTi) oil with approval is required ACEA C3 and viscosity 5W-30.

It is important to consider that when complete oil change with flushing the volume may increase by 0.3–0.5 l due to residues in the oil channels. Below is a table with exact data:

Engine	Oil volume (l)	With filter replacement	Oil type
MR20DE (2.0 l, petrol)	4.3	4.5	5W-30, 5W-40
QR25DE (2.5 l, petrol)	4.8	5.0	5W-30, 5W-40
M9R (2.0 l, diesel)	5.4	5.7	5W-30 (ACEA C3)
YD25DDTi (2.5 l, diesel)	6.2	6.5	5W-30 (ACEA C3)

⚠️ Attention: When changing oil on diesel engines Nissan X-Trail T31 be sure to check the level 10–15 minutes after filling - due to the design of the pan, errors in the dipstick readings are possible.

2. Transmission fluids: CVT, manual transmission and transfer case

Nissan X-Trail T31 equipped with three types of transmissions: CVT Jatco RE0F10A, manual transmission FS6R31A and all-wheel drive system All Mode 4x4-i. Each unit requires different fluids:

• 🔧 CVT (CVT): original liquid Nissan NS-2 or NS-3 (volume - 7.9 l with a full replacement, 5.4 l with a partial replacement). Replacement is required every 60,000 km.
• ⚙️ Manual transmission: oil API GL-4 (viscosity 75W-85 or 75W-90), volume - 2.8 l.
• 🔄 Transfer case (4WD): liquid Nissan Matic S or equivalent ATF D-III, volume - 1.1 l.
• 🛡️ Rear differential: oil API GL-5 (viscosity 80W-90), volume - 1.0 l.

⚠️ Attention: When replacing fluid in the variator Nissan X-Trail T31 prohibited use universal ATF fluids (for example, Dexron III). This leads to belt slippage and cones failure.

For all-wheel drive versions, an additional check of the level in the transfer case and rear differential is required - these components are often forgotten to be serviced, which leads to accelerated wear.

3. Cooling system: antifreeze and replacement nuances

Antifreeze volume in Nissan X-Trail T31 depends on the engine type and configuration. The manufacturer recommends using green antifreeze based on ethylene glycol (specification Nissan L250 or analogues G11). Total volume of the cooling system:

• ❄️ Gasoline engines (MR20DE, QR25DE): 7.0–7.5 l.
• ⛽ Diesel engines (M9R, YD25DDTi): 8.0–8.5 l (due to additional charge air cooler).

When replacing antifreeze, it is important to consider:

1. The liquid must be drained when cold engineto avoid thermal burns.
2. After adding new antifreeze, you must bleed the systemby opening the heater tap to maximum.
3. For the first 500 km after replacement, keep an eye on the level - hidden air pockets are possible.

⚠️ Attention: Mixing antifreeze of different colors (for example, green G11 and red G12) leads to the formation of sediment and clogging of the radiator. When switching to another type of fluid, it is required complete flushing of the system.

What happens if you add water instead of antifreeze?

Use of water in the cooling system Nissan X-Trail T31 leads to corrosion of aluminum parts (cylinder head, radiator), overheating of the engine in winter and the risk of rupture of pipes when freezing. Even short-term use of water requires subsequent flushing and refilling with antifreeze.

4. Brake system and hydraulics

Brake fluid in Nissan X-Trail T31 must comply with the standard DOT 4. System volume is 0.8–1.0 l depending on the configuration (with or without ABS). The manufacturer recommends replacement every 2 years or 40,000 km, since the liquid is hygroscopic and loses its properties.

When replacing brake fluid, follow the algorithm:

Remove the master cylinder reservoir cap

Draw out old fluid with a syringe

Fill with new fluid to the maximum

Bleed the brakes according to the following diagram: rear right → front left → rear left → front right

Check for air in the system -->

⚠️ Attention: If after replacement the brake pedal becomes “soft”, this is a sign air in the system. Re-pumping is required. Also check the condition of the brake hoses - X-Trail T31 they often crack after 100,000 km.

For models with ESP (electronic stabilization system) the volume of liquid can increase to 1.2 liters. In this case, bleeding must be carried out using a diagnostic scanner to activate the ABS valves.

5. Fuel system: tank volume and recommendations for gasoline/diesel fuel

Fuel tank volume Nissan X-Trail T31 is the same for all modifications - 65 liters. However, the actual range depends on the engine type and operating conditions:

• ⛽ Gasoline engines (MR20DE, QR25DE): recommended gasoline - AI-95. Usage AI-92 allowed, but may lead to detonation under high loads.
• ☣ Diesel engines (M9R, YD25DDTi): requires diesel fuel with a cetane number of at least 51. In winter, the use of anti-gel is mandatory.

⚠️ Attention: On diesel X-Trail T31 with mileage over 150,000 km often clogs diesel particulate filter (DPF). If the car is used primarily in the city, it is recommended to go on the highway every 5,000 km to forced regeneration (20-30 minutes of driving at speeds above 2,500 rpm).

For gasoline versions, it is critical to monitor the condition fuel filter — its replacement is required every 40,000 km. On diesel engines, the filter is changed more often: every 20,000 km or when the water sensor in the separator is activated.

6. Power steering (power steering): fluid and volumes

Power steering system in Nissan X-Trail T31 requires liquid type PSF-2 or ATF D-III. System volume - 1.0 l, but when replacing, 0.8–0.9 liters is enough, since complete draining is impossible without disassembling the rack.

Signs that power steering fluid needs replacing:

• 🔊 The pump creaks or hums when turning the steering wheel.
• 🛢️ Darkening of the liquid (a sign of oxidation).
• 🔄 Increased effort on the steering wheel during maneuvers.

⚠️ Attention: On X-Trail T31 with a mileage of more than 150,000 km they often wear out rack seals. If after replacing the power steering fluid the level drops quickly, diagnostics for leaks is required.

To change power steering fluid:

1. Raise the front of the car (to make bleeding easier).
2. Drain the old fluid through the return hose.
3. Pour in new fluid in small portions, turning the steering wheel from lock to lock.

7. Other fluids: air conditioning, windshield washer, shock absorbers

In addition to basic fluids, Nissan X-Trail T31 Maintenance of other systems is also required:

• ❄️ Air conditioning: refilling with freon R-134a (500–600 g). Change the oil in the compressor - every 2 years.
• 💦 Windshield washer: tank volume - 5.0 l. In winter, use a liquid with a freezing point no higher than -25°C.
• 🔧 Shock absorbers: rear struts (if they are oil-based) may require adding special oil Nissan Shock Absorber Oil.

⚠️ Attention: When refilling the air conditioner Nissan X-Trail T31 Be sure to check the oil level in the compressor. Its deficiency leads to jamming of the clutch and failure of the climate system.

For shock absorbers it is critical to use only original oil — replacement with universal analogues worsens the characteristics of the suspension and can lead to leakage of seals.

FAQ: Frequently asked questions about filling volumes

❓ How much oil to pour into the engine QR25DE when replacing without a filter?

When changing the oil without filter replacement into the engine QR25DE required 4.5 l. However, it is recommended to always change the filter, since up to 0.3 liters of old oil with contaminants remains in it.

❓ Is it possible to use antifreeze G12++ instead of the original Nissan L250?

Yes, antifreeze G12++ (red or purple) compatible with Nissan L250, but required complete flushing of the system before replacement. Mixing different types of antifreeze is unacceptable.

❓ How often should the fluid in the variator be changed? Jatco RE0F10A?

Official regulations - every 60,000 km. However, when operating in difficult conditions (towing, off-road), the interval is reduced to 40,000 km. Use only Nissan NS-2 or NS-3.

❓ What happens if you exceed the volume of oil in the engine M9R?

Excessive oil level in diesel engine M9R leads to foaming, increased pressure on the seals and the risk of oil squeezing out through the crankcase ventilation. The maximum permissible level is 5 mm above the MAX mark on the dipstick.

❓ What kind of brake fluid to fill in X-Trail T31 with ABS?

For models with ABS And ESP brake fluid required DOT 4 with a boiling point not lower 230°C. Suitable brands: Nissan Brake Fluid, ATE SL.6, Castrol React DOT4.
