Best Engine Oil for Peugeot 107 1.0 (68 HP)
The Peugeot 107 carved out a loyal following among British drivers looking for honest, affordable urban transport. Produced between 2005 and 2014, this tiny hatchback offered Peugeot’s characteristic styling flair on a platform developed jointly with Toyota and Citroen. Under the bonnet sits the Toyota-designed 1KR-FE three-cylinder engine, a unit praised for its reliability but one that places specific demands on lubricant quality. With an oil capacity of just 3.1 litres including the filter, every millilitre matters — degraded or incorrect oil has an outsized effect on engine health compared to larger-displacement power units. This guide walks through the correct oil specification, viscosity choices, and practical ownership considerations specific to the Peugeot 107.
Quick Answer: Recommended Oil
For Peugeot 107 1.0 (68 HP):
- Primary viscosity: SAE 0W-20
- Alternative viscosity: SAE 5W-30 (for reduced oil consumption)
- ACEA norm: C2
- Oil capacity: 3.1 litres with filter (2.8 L without)
Key decision: 0W-20 delivers the best fuel economy and meets the manufacturer’s primary recommendation. However, many experienced 107 owners prefer 5W-30 to address oil consumption — a legitimate trade-off that sacrifices a marginal fuel economy gain for greater peace of mind between services.
The 1KR-FE Three-Cylinder Engine
The 1KR-FE is a 998cc aluminium three-cylinder unit producing 68 horsepower at 6,000 RPM and 93 Nm of torque at 3,600 RPM. Toyota engineered this powerplant for maximum efficiency and minimal weight, and all Peugeot 107s rolled off the production line at Toyota’s Kolin plant in the Czech Republic alongside their Citroen C1 and Toyota Aygo siblings. Despite the shared mechanicals, the Peugeot ownership experience differs in several meaningful ways — from dealer network and parts pricing to the specific maintenance culture that develops around a French-branded vehicle.
The engine features a timing chain with a hydraulic tensioner rather than a cambelt. This eliminates a major scheduled maintenance cost, though the chain tensioner relies on consistent oil pressure to function correctly. Low oil level or heavily degraded oil can allow chain slack, producing a characteristic rattle on cold starts that many 107 owners report. The cure is straightforward: maintain the correct oil level and change it regularly.
A known weak point across all vehicles using this engine is the plastic water pump housing, which becomes brittle over time and can crack without warning. While not an oil-related failure, a sudden coolant loss event that causes overheating will rapidly destroy oil film integrity in such a small-capacity engine. Keeping an eye on coolant condition is a sensible companion habit to regular oil maintenance.
Understanding the Viscosity Debate: 0W-20 vs 5W-30
This is the single most discussed topic among Peugeot 107 owners in the UK, and for good reason. The manufacturer’s primary recommendation of 0W-20 delivers measurable fuel economy benefits — potentially 1-2 mpg in mixed driving — and provides excellent cold-start protection during British winters. For an engine that is often asked to make short journeys in urban settings, rapid oil circulation at low temperatures is genuinely valuable.
However, the 1KR-FE has a documented tendency toward oil consumption, particularly as mileage accumulates beyond 60,000 miles. With only 3.1 litres of total capacity, losing even 500ml between services represents a significant proportion of the engine’s oil volume. Thin 0W-20 is more likely to pass worn valve stem seals and piston rings than a heavier 5W-30 grade.
Many pragmatic 107 owners in the UK settle on 5W-30 meeting ACEA C2 as their preferred choice, accepting a negligible fuel economy penalty in exchange for a stable oil level between services. This is not a controversial position — it is a practical response to the realities of an ageing, high-mileage small engine. If your 107 has fewer than 50,000 miles and shows no signs of consumption, 0W-20 remains the optimal choice. Beyond that threshold, monitoring the dipstick after each fill will tell you whether stepping up to 5W-30 makes sense.
Whichever viscosity you select, the critical requirement is ACEA C2 compliance. This low-SAPS (Sulphated Ash, Phosphorus, Sulphur) specification protects the catalytic converter and ensures compatibility with the engine’s emissions systems.

Premium Alternative: Mobil 1 ESP x2 0W-20 ExxonMobil’s ACEA C2-compliant 0W-20 brings exceptional thermal stability and shear resistance. The advanced synthetic base oils maintain viscosity over extended periods, which matters when you are working with just 3.1 litres of total capacity. Slightly more expensive at £38–48 for 4 litres, but a strong option for owners who want maximum protection within the 0W-20 bracket.
Strong Contender: Shell Helix Ultra Professional AS-L 0W-20 Shell’s PurePlus technology uses natural gas-derived base oils for outstanding purity and consistent molecular structure. The AS-L variant meets ACEA C2 requirements and provides reliable protection across the full temperature range. Priced at £35–45 for 5 litres, it represents solid value with proven performance credentials.
Budget-Conscious Pick: Castrol EDGE 0W-20 Castrol’s Fluid Titanium technology reinforces oil film strength under pressure, addressing the concern some owners have about thin oils in an ageing three-cylinder. ACEA C2 approved and readily available at £28–38 for 4 litres from most UK motor factors and online retailers. A sensible choice for owners performing frequent DIY changes who want dependable quality without premium pricing.
Oil Change Intervals
Peugeot Official Recommendation: 12,500 miles or 12 months, whichever comes first.
Recommended Practice: 6,000–8,000 miles or annually.
The official interval is generous for an engine with such limited oil capacity. Over 12,500 miles, those 3.1 litres absorb a significant concentration of combustion byproducts, fuel dilution from cold starts, and moisture from condensation — particularly if the car is used for short urban trips, which is exactly the driving pattern most 107s endure.
Halving the official interval is inexpensive insurance. A quality ACEA C2 oil and filter for the 107 costs under £30 total, making this one of the cheapest engines to service in the entire UK market. The oil change itself is straightforward: the sump plug and filter are easily accessible, and the small capacity means the job takes fifteen minutes with basic tools.
Reduce intervals further if:
- The car covers mostly short trips under five miles
- It sits idle for weeks at a time between uses
- Oil consumption is noticeable between services
- The engine has covered more than 80,000 miles
Why Correct Oil Matters in a Low-Capacity Engine
The Peugeot 107’s 3.1-litre oil capacity is roughly 40% less than a typical family car engine. This simple fact has practical consequences that are easy to underestimate.
Contamination concentration: Every engine produces combustion byproducts that end up in the oil. In a larger sump, these contaminants are diluted across a greater volume. In the 107, the same quantity of soot, fuel, and acids is concentrated in significantly less oil, accelerating additive depletion and viscosity breakdown.
Thermal cycling: Less oil means less thermal mass to absorb heat. The oil in a 107 reaches operating temperature faster, which is beneficial, but also suffers greater temperature swings under varying loads. Quality synthetic oils with stable base stocks handle this cycling far better than budget mineral alternatives.
Chain tensioner health: The hydraulic timing chain tensioner depends on consistent oil pressure to keep the chain taut. Low oil level or heavily degraded oil with reduced pressure characteristics can allow tensioner bleed-down overnight, producing the chain rattle that many 107 owners hear on morning start-up. Persistent rattling accelerates chain and sprocket wear — a repair that dwarfs the cost of regular oil changes.
Dipstick discipline: With margins this tight, checking the oil level fortnightly is not excessive. It takes thirty seconds, costs nothing, and provides the earliest warning of developing consumption or leaks. The dipstick on the 1KR-FE is clearly marked and easily accessible — there is no excuse for neglecting this basic check.
The Peugeot 107 Ownership Perspective
The 107 occupies a particular place in the UK car market. It was bought by a broad mix of drivers — newly qualified teenagers, city commuters, retirees wanting economical local transport, and budget-conscious families running it as a second car. What unites these owners is the desire for minimal running costs, and the 107 delivers spectacularly well on that promise.
Parts are abundant and cheap. Insurance groups are rock-bottom. Road tax is negligible. And oil changes, even with premium synthetic lubricant, cost less than a modest restaurant meal. The 1KR-FE engine, maintained with the right oil at sensible intervals, will reliably cover well over 150,000 miles. Neglected examples suffer chain rattle, increased consumption, and eventually terminal bearing wear — failures that are entirely preventable with basic care.
For owners performing their own maintenance, the 107 is among the most accessible cars to work on. The engine bay is uncluttered, the drain plug and filter require no special tools, and the small oil volume means even the most expensive synthetic on the market costs under £25 per change. Spending a few extra pounds on ACEA C2-compliant oil from a reputable brand is the single most cost-effective thing any 107 owner can do.
Conclusion
The Peugeot 107 1.0 requires ACEA C2-compliant engine oil in either SAE 0W-20 (primary) or SAE 5W-30 (alternative), with a total capacity of 3.1 litres including the filter. For low-mileage examples, 0W-20 from Total Quartz INEO First or Mobil 1 ESP x2 provides the best combination of fuel economy and protection. For higher-mileage cars showing signs of oil consumption, stepping up to a quality 5W-30 meeting ACEA C2 is a perfectly sound strategy.
Change the oil every 6,000–8,000 miles, check the dipstick fortnightly, and use a reputable ACEA C2 product. At under £30 per service, this modest investment protects the timing chain tensioner, minimises consumption, and keeps the little three-cylinder running cleanly for years to come. The Peugeot 107 asks very little of its owner — the least it deserves is the right oil.
