The Nissan QR25DE is a 2,488 cc, inline‑four naturally aspirated petrol engine produced between 2001 and 2017. It features an aluminium block and head, dual overhead camshafts (DOHC), and 16 valves with electronic fuel injection. This engine was designed for a balance of smooth power delivery and reliability in Nissan's global compact SUV and sedan platforms.
Fitted to models such as the X — Trail (T30/T31), Qashqai (J10), and Sentra (B15/B16), the QR25DE was engineered…
Production years 2001–2007 meet Euro 3 standards; 2008–2017 models meet Euro 4 depending on market (Nissan Technical Service Bulletins, EU Directive 98/69/EC, 2002/80/EC).
The Nissan QR25DE is a 2,488 cc inline‑four naturally aspirated petrol engine engineered for compact SUVs and sedans (2001-2017). It combines electronic fuel injection with a DOHC 16-valve valvetrain to deliver smooth, linear power. Designed to meet Euro 3 and Euro 4 emissions standards, it prioritizes durability and everyday drivability.

The Nissan QR25DE was used across Nissan's T30/J10 platforms with transverse mounting. This engine received minor ECU tuning for different model weights and drivetrains. All adaptations are documented in OEM technical bulletins.
The QR25DE's primary reliability risk is timing chain tensioner wear on high-mileage examples, with elevated incidence in vehicles using lower-quality oil. Nissan service data indicates tensioner failure is a common cause of cold-start rattle after 150,000 km, while ignition coil failure can occur if maintenance is neglected. Extended service intervals make adherence to OEM oil specifications critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The QR25DE is generally a very reliable and durable engine. Its simple design and robust construction contribute to longevity. The main long-term concern is the timing chain tensioner, which requires good oil maintenance. With regular servicing using the correct oil, many QR25DE engines have comfortably exceeded 300,000 km.
The most frequent issues are timing chain tensioner wear (causing a cold-start rattle), ignition coil failures, valve cover gasket leaks, and, on very high-mileage engines, oil consumption due to piston ring wear. These are well-documented in Nissan service manuals and are typically straightforward to address with OEM parts.
The QR25DE was used in a wide range of Nissan vehicles, including the X-Trail (T30 and T31), Qashqai (J10), Sentra (B15/B16, particularly the SE-R and Spec V trims), and the Rogue (US market equivalent of the X-Trail). It was Nissan's primary 2.5L petrol engine for over 15 years.
The QR25DE has modest tuning potential. Basic modifications like a performance air filter, free-flow exhaust, and ECU chip tuning can yield gains of 10-15 kW. More significant power increases require internal modifications like camshafts or forced induction, which are often not cost-effective for this engine.
Fuel economy is moderate for its size. Expect figures around 9.0–10.5 L/100km in combined driving for an SUV like the X-Trail. Real-world consumption varies based on driving style and vehicle weight, with highway driving being more efficient.
Yes. The Nissan QR25DE is an interference engine. If the timing chain were to fail or jump significantly, the pistons can collide with the open valves, causing severe internal engine damage. While the chain itself is robust, a failing tensioner can lead to chain slack and potential jump.
Nissan originally specified API SL or SM grade oil, typically in 5W-30 viscosity. Modern, high-quality API SN or SP oils in the same viscosity range are suitable and often provide better protection. Always consult the owner's manual for the specific recommendation for your vehicle and climate.
