The Peugeot 118 (XL5) is a 1,124 cc, inline‑four naturally aspirated petrol engine produced between 1983 and 1988. It features a single overhead camshaft (SOHC) with two valves per cylinder and a single — barrel carburetor. This engine delivered outputs of 44 kW (60 PS) and 88 Nm, prioritizing straightforward mechanics and cost — effective ownership for compact family cars.

Production years 1983–1988 predate formal Euro standards; emissions compliance is based on national regulations of the era .
The Peugeot 118 (XL5) is a 1,124 cc inline‑four naturally aspirated petrol engine engineered for supermini applications (1983-1988). It combines a simple carburetor with a robust SOHC valvetrain to deliver economical and reliable performance. Designed for pre‑Euro emissions regulations, it prioritizes low cost and ease of maintenance.

Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the XL5 engine is known for its mechanical simplicity and durability when properly maintained. Its low power output and robust design mean it's rarely stressed. Key to longevity is regular oil changes, valve clearance checks, and keeping the carburetor in good order. The distributor drive gear is the most common specific wear item.
The most frequent issues are wear of the distributor drive gear causing timing problems, carburetor malfunctions leading to poor running, and noisy tappets due to neglected valve clearance adjustments. Oil leaks from the rocker cover gasket are also common on older examples. These are well-documented in Peugeot service manuals.
The XL5 engine was used exclusively in the first-generation Peugeot 205, specifically in the 1.1 and 1.1 GR trim levels, from its launch in 1983 until 1988. It was not fitted to any other Peugeot or Citroën models, making it unique to the early 205.
Minor power gains are possible through carburetor and exhaust upgrades, but significant increases are difficult due to its small displacement and restrictive 8-valve head. It's better suited to its role as an economical runabout than a performance project. A well-tuned standard engine offers the best balance of economy and reliability.
Good for its era. Expect around 7.5 L/100km (city) and 5.5 L/100km (highway), translating to approximately 38 mpg UK (combined). Real-world figures often fall between 35-45 mpg UK, making it a very economical choice for urban commuting and short trips.
No. The XL5 is a non-interference engine. This means if the timing chain were to fail or jump, the pistons will not contact the valves. While this prevents catastrophic engine damage, a broken chain will still leave you stranded and require repair.
Peugeot originally specified a mineral 15W-40 engine oil. While a good quality semi-synthetic 10W-40 can be used for added protection, a full synthetic is unnecessary. Regular changes (every 10,000 km or annually) are more important than the oil type for this engine.
