The 1.2 PureTech engine in the Peugeot 208 is known for its efficiency. The engine is also known for increased oil consumption from around 75,000 kilometres. Contamination of the intake ports and worn valve stem seals are often at the root of this problem, which can lead to camshaft shift and crankshaft damage. Fortunately, the problem can be prevented and solved. Read how to recognise this and what you can do about it.
Why does the PureTech engine use so much oil?
Oil consumption in PureTech engines can rise sharply. Peugeot itself uses a standard of 1 litre per 1,000 kilometres, but owners regularly report even higher consumption of 1 litre per 750 to 1,750 kilometres. This points to a structural problem in certain model years of the Peugeot 208.
The primary cause is contamination of the intake ports and intake valves. This process works like a downward spiral. Deposits build up in the ports and on the valves. These deposits result in poorer combustion of the air-fuel mixture. That incomplete combustion leads to even more contamination. This contamination eventually reaches the piston scraper rings. As a result, the engine becomes even dirtier. Oil consumption increases further.
A second common cause is wear of the valve stem seals. These components are also called valve stem rubbers. The rubbers seal the valve stem. They prevent engine oil from leaking into the combustion chamber. The rubbers are exposed to heat and ageing. As a result, they can dry out and harden. They then lose their sealing function, allowing oil to enter the cylinder and be burned along with the fuel.
‘ With serious oil consumption, the MOT test will also cause problems. ’
How do you recognise oil consumption in your Peugeot 208?
There are clear symptoms that point to increased oil consumption. The most noticeable sign is blue or grey smoke from the exhaust, especially when you accelerate. Engine oil is being burned along with the fuel in the cylinders. This causes the blue colour. A burning oil smell around the car after driving is also a warning sign.
In addition, the oil level drops more and more between service intervals. Check the level regularly with the dipstick. Under normal use, the level hardly drops between two services. With severe oil consumption, the MOT test will also cause problems. Exhaust emissions will then be excessive.
The link with camshaft shift
Oil consumption and camshaft shift are closely related. With camshaft shift, the camshaft moves in relation to the crankshaft position. The engine contains too little oil because of increased consumption. Lubrication of moving parts is therefore reduced. The camshaft is sensitive to this. The crankshaft system is also sensitive to it. This system includes the crankshafts that control the engine movements. Insufficient lubrication leads to accelerated wear. This ultimately results in the camshaft shifting relative to the crankshaft position.
This problem is made worse by incorrect use of oil. Deferred maintenance also aggravates the problem. The PureTech engine requires specific oil specs that meet PSA B71 2290 and ACEA C2 standards. PSA B71 2290 is the quality standard of car manufacturer PSA for this engine. ACEA C2 is a European standard for low-viscosity oil. Some oils do not meet these requirements. These oils provide insufficient protection under high load and high temperatures.
Camshaft shift manifests itself in poor engine performance. An irregular idle speed is also a symptom. Faults in the variable valve timing occur. This system adjusts the valve opening dynamically to the engine’s needs. In severe cases, the engine can seize completely. Regular oil checks are therefore essential. Correct maintenance prevents this damage.
Which oil should you use?
For the 1.2 PureTech engine, the correct oil specification is important. Fanfaro XTR 0W30 is often recommended. This oil meets the PSA B71 2290 and ACEA C2 requirements. PSA B71 2290 is the quality standard of car manufacturer PSA for this engine. ACEA C2 is a European standard for low-viscosity oil. This oil helps prevent sludge formation. The oil provides extra protection under high load.
For a standard oil change you need an average of 3.25 litres. The recommended interval is every 15,000 kilometres or annually. Changing the oil more frequently is sensible if you do a lot of short journeys or drive under heavy conditions. Short journeys cause more condensation and contamination in the engine. This worsens the oil consumption problem.
Solutions for increased oil consumption
The approach depends on the cause. If contamination of the intake ports and valves is the problem, a professional cleaning improves the situation. This is a solvable issue. It prevents further damage. The cleaning removes deposits. As a result, the engine burns more efficiently again.
If the valve stem seals are worn, replacement is necessary. Valve stem seals are also called valve stem rubbers. These are rubbers that seal the valve stem. Replacement is the only definitive solution. It stops oil consumption caused by leaking valve stem rubbers. Replacement prevents several problems:
- Progressive oil consumption and increased maintenance costs
- Engine damage due to oil shortage and reduced lubrication
- Damage to the catalytic converter caused by burnt engine oil
- MOT failure due to excessive exhaust emissions
Maintenance and prevention are decisive
Acting early makes all the difference. If you notice abnormal oil consumption, have it checked immediately by a specialist. Do not wait until the problem gets worse. Regularly checking the oil level between services is a simple but effective measure.
Always use the correct oil. The oil must meet the PSA B71 2290 and ACEA C2 standards. PSA B71 2290 is the quality standard of car manufacturer PSA for this engine. ACEA C2 is a European standard for low-viscosity oil. If in doubt, choose the specifications from the handbook of your Peugeot 208. Some alternatives are cheaper. These alternatives do not meet these requirements. Do not use them. That makes the problem worse.
During services, explicitly ask for attention to the intake ports, valves and valve stem seals. Have the mechanic check these components. The mechanic checks for contamination. The mechanic also checks for wear. Early detection saves expensive repairs to the camshaft later on. It also saves repairs to the crankshaft system. This system includes the crankshafts that control the engine movements.
What to do if you notice symptoms
You notice blue smoke from the exhaust. A burning oil smell is also a symptom. The oil level drops quickly. First check the oil level. Top up with the correct oil if necessary. Do not continue driving with too little oil. That will immediately lead to serious engine damage.
Then book a diagnostic check at a garage. Choose a garage that is familiar with PureTech problems. They determine the cause. They assess whether cleaning is sufficient. They also assess whether the valve stem seals need to be replaced. Ask about experience with this specific engine problem. Not every garage is equally familiar with the typical weak points of this engine.
Also keep track of your maintenance history. This is documentation of all your services, repairs and oil top-ups. Record the following data:
- When you top up oil
- How much oil you top up
- Which symptoms you notice
This information helps the mechanic with the diagnosis. The information is later useful in warranty cases. This documentation is also valuable when selling the car.

Frequently asked questions
The main causes of increased oil consumption in the Peugeot 208 PureTech are contamination of the intake ports and intake valves, which causes poorer combustion of the mixture and eventually contaminates the piston scraper rings. In addition, the valve stem seals (valve stem rubbers) wear or harden, allowing oil to leak into the combustion chamber.
You can often recognise early problems with camshaft shift (VVT) by an irregular or rough idle, loss of power when accelerating, poorer cold starting and sometimes an engine warning light with fault codes relating to camshaft position/VVT control. Rattling or ticking engine noises when starting or at a certain engine speed can also indicate wear or contamination in the camshaft adjuster. If the camshaft no longer adjusts correctly or responds slowly, torque and power deteriorate, especially at low or high revs, and fuel consumption increases. Driving for a long time with these issues can cause additional mechanical wear, a contaminated combustion chamber and ultimately serious engine damage.
Always use the prescribed oil (for example 0W30 according to PSA B71 2290/ACEA C2) and, if necessary, shorten the oil change interval (maximum 15,000 km or yearly, preferably more often if you mainly drive short journeys) to limit sludge and contamination. Between services, regularly check the oil level and top up in good time to avoid driving with an oil shortage – and thus extra wear to, among other things, the camshaft and piston rings. Have the intake ports and valves inspected periodically and professionally cleaned if necessary, to combat contamination that leads to poorer combustion and increased oil consumption. React immediately to signs such as blue/grey smoke, the smell of burning oil or ticking noises in the valve and camshaft area, and have valve seals and other wear parts replaced in good time if needed.
Diagnosis of camshaft shift problems usually costs several hundred euros, depending on the test and disassembly time required. Repair costs can range from around €500–€1,500 if cleaning and minor parts are sufficient, to well over €2,000 when, for example, valve stem seals or other internal engine parts need to be replaced. First have a targeted diagnosis carried out by a specialist with experience of PureTech engines, including reading fault codes and checking for contamination and wear. The advice is not to wait too long with repairs once problems have been confirmed, in order to prevent further engine damage and higher costs.
The increased oil consumption in the 1.2 PureTech engine of the Peugeot 208 occurs regularly and is regarded as a structural problem in certain model years, especially at higher mileages. This can lead to additional maintenance costs (cleaning intake ports, replacing valve stem seals) and an increased risk of engine damage if oil is not topped up in time. Used-car buyers are aware of this, so cars with demonstrable oil problems are less popular. In practice, this depresses the resale value compared with similar models without a known oil consumption problem.
