Artigo atualizado em 27 de July de 2026 por João Daniel

Changing the oil on schedule and using the exact specification recommended by the manufacturer is the number one rule for preserving the mechanics of your Citroën, maintaining fuel economy and avoiding severe damage, from classic 2.0 16V engines to modern turbocharged units with oil-bathed belts.

If you have any questions about What is the best oil for Citroën?Check out the official PSA/Stellantis standards, the recommended viscosity for each engine type in Brazil, and the best brands on the market.

The Golden Rule: Understanding the PSA/Stellantis Standards

Before choosing a lubricant brand, the most critical factor is to check the PSA approval standard Printed on the packaging label. Citroën designs its engines to work with specific additives that protect everything from seals and turbines to internal belts.

Main PSA Standards for the Brazilian Market:

• PSA B71 2290: Standard for modern Flex and gasoline engines of the brand, with Low SAPS (low ash emission) technology. Essential for engines with modern catalytic converters and complex emission systems. Typical viscosity: 5W30.
• PSA B71 2312: Developed for maximum energy efficiency and protection against low-speed pre-ignition (LSPI). Highly recommended for turbocharged engines and modern PureTech engines. Typical viscosity: 0W30.
• PSA B71 2296: Classic standard focused on high thermal resistance and wear protection in older design engines and severe use. Typical viscosity: 5W40.
• PSA B71 2010 / Fiat 9.55535: Used in the recent line with Firefly and Turbo 200 engines. Typical viscosity: 0W20 or 5W30.

Citroën Engine Recommendation Table

Detailed Specifications: 2.0 16V and 1.6 THP engines

1. 2.0 16V Naturally Aspirated Engine (EW10A Block)

Very present in classic models of the brand in Brazil such as C4 Pallas, C4 Hatch, C5 and Xsara PicassoThe 143/151 hp EW10A engine is robust, but requires attention to viscosity to ensure the correct functioning of the hydraulic tappets and the variable valve timing (VVT) system.

• Ideal Viscosity: 5W40 Synthetic
• Main Standard: PSA B71 2296 (for 5W40)
• Maintenance Tip: Avoid using mineral or semi-synthetic oils (such as the old 10W40). Using unsuitable oil in the 2.0 engine causes tappet noise when cold and sludge formation on the valve cover.

2. 1.6 THP Turbo Engine (EP6 Family – Gasoline and Flex)

Equipping high-performance models such as C4 Lounge, C4 Cactus THP and the DS line (DS3, DS4, DS5)The THP engine features direct fuel injection and a twin-geometry turbocharger. It is a thermal assembly that operates under high temperature and pressure.

• Ideal Viscosity: 0W30 Synthetic or 5W30 Synthetic (both must be 100% synthetic).
• Main Standard: PSA B71 2312 (preferably 0W30) or PSA B71 2290 (for 5W30).
• Special Attention: The turbocharger uses the engine’s own oil for lubrication and shaft cooling. Oils outside of specifications oxidize rapidly under high temperatures, generating carbon in the turbine feed pipe (aerotube) and carbon buildup on the intake valves due to direct injection.

Engine Care for the 1.2 PureTech (Oil-Bath Timing Belt)

If your model is the C3 equipped with the 1.2 PureTech 3-cylinder engine, the accuracy must be absolute. The timing belt operates submerged in engine oil..

The use of lubricants that do not meet the standard. PSA B71 2312 This causes chemical degradation of the belt rubber. The released residue clogs the oil pickup screen, leading to loss of lubrication pressure and severe damage to the block. Use exclusively approved 0W30 synthetic oil.

The Best Oil Brands for Citroën

Leading brands in the market that have product lines specifically certified to meet PSA/Stellantis requirements:

1. TotalEnergies (Quartz Ineo / Quartz 9000 Line): Long-standing partner of Citroën. Products such as the Quartz Ineo First 0W30 (for THP and PureTech) and Quartz 9000 5W40 (for the 2.0 engine) were developed in conjunction with the automaker.
2. Mobil (1 ESP / Super 3000): It offers excellent thermal stability in turbocharged engines and optimal protection against cold wear.
3. Motul (8100 Eco-clean / X-cess line): Highly recommended by enthusiasts and workshops specializing in French-style engines, especially for remapped or heavily used THP engines.
4. Castrol (EDGE / Magnatec): It offers an excellent protective film during cold starts, reducing initial engine wear.

Recommended Replacement Interval

• Normal Conditions (Road/Mixed Use): Every 10,000 km or 12 months.
• Severe Use (Heavy urban traffic, short daily trips less than 8 km): Reduce the interval to 5,000 km or 6 months.

Always replace the oil filter Changing the oil along with the lubricant. Keeping the old filter contaminates the new oil immediately with accumulated residue and metal shavings.

Summary: The best oil for your Citroën depends directly on the engine under the hood. While the 2.0 16V engine works perfectly with a 5W40 PSA B71 2296THP and PureTech engines require oil technology. 0W30/5W30 with PSA B71 2312 or B71 2290 approval.. Adhering to the standard guarantees a durable and high-performance engine.
