Best Engine Oil for Peugeot 2008 1.2 PureTech Turbo (100/130 HP)
The second-generation Peugeot 2008 (2020 onwards) transformed Peugeot’s compact crossover from a raised supermini into a genuinely distinctive small SUV. Its most popular petrol engine is the 1.2 PureTech turbocharged three-cylinder (EB2ADTS), available in 100 HP and 130 HP outputs. The 2008 weighs approximately 1,200 kg — heavier than the 208 hatchback but lighter than the 3008. This positions it in the middle of the PureTech range for oil stress, but the wet timing belt inside the engine makes oil selection a matter of engine survival regardless of vehicle weight.
Quick Answer: Recommended Oil
For Peugeot 2008 1.2 PureTech (100/130 HP):
- Recommended viscosity: SAE 0W-30
- Oil capacity: 3.5 litres with filter (3.2 L without)
- Required norms: ACEA C2, PSA B71 2312
Critical: Only use oil with explicit PSA B71 2312 approval. This specification protects the wet timing belt. Generic ACEA C3 products will damage the belt rubber.
The Wet Timing Belt in the 2008
The EB2ADTS uses a toothed rubber timing belt running inside the engine, permanently submerged in sump oil. This belt-in-oil design was engineered to eliminate conventional belt replacement intervals, but it has become the PureTech’s most documented failure point. Fuel dilution from direct injection degrades the oil, which attacks the belt rubber, causing it to swell, shed particles, and clog the oil pump strainer. Engine seizure follows.
The 2008’s typical UK usage — urban commuting, school runs, short suburban trips — maximises fuel dilution because the engine rarely reaches full operating temperature. PSA B71 2312 oil is formulated to remain chemically neutral to the belt rubber even under fuel contamination.
Stellantis recall and compensation: PSA issued recalls from 2021 covering PureTech belt inspections. Stellantis’s 2025 compensation programme acknowledges systemic belt failures. Budget for precautionary belt replacement at 60,000-70,000 miles (£400-600).
Oil Consumption Monitoring
Some PureTech engines exhibit elevated oil consumption (0.5-1.0L per 1,000 miles) from carbon-clogged piston ring drain holes. On the 3.5-litre sump, losing 0.5L represents 14% of total volume. If the level drops far enough, the wet belt loses its oil immersion and degrades rapidly. Check the dipstick fortnightly.

Oil Change Intervals
Peugeot Official: Variable service indicator, up to 20,000 miles / 24 months.
Recommended: 10,000 miles or 12 months maximum. For short-trip urban driving, reduce to 6,000-8,000 miles. Drive warm regularly — 30-minute motorway runs evaporate fuel from the sump.
Conclusion
The Peugeot 2008 1.2 PureTech requires SAE 0W-30 meeting PSA B71 2312, with 3.5 litres capacity. The wet timing belt makes this one of the most oil-sensitive engines in the compact SUV segment. Confirm B71 2312 on the label, check the dipstick fortnightly, and change at sensible intervals.
