DS 4 Oil Burning & Oil Consumption Prevention Kit (1.6 THP)

DS 4 Oil Burning and Oil Consumption Problem

The 1.6 THP (EP6) engine of the DS 4 (2011-2018, premium hatchback) is known for the chronic oil consumption of the Prince family developed jointly with BMW. The cause is usually worn valve stem seals and piston rings: oil seeps into the combustion chamber and burns. Consumption of 0.5-1 L per 1,000 km and blue smoke at idle are typical. Keeping the oil feeding the turbo clean is also critical; dirty oil quickly wears the turbo and the chain tensioner. The correct viscosity + additive is decisive in bringing consumption under control.

Oil Burning Prevention Kit for the DS 4

• DS 4 that consumes oil → 5 L Brava Extreme 9000 5W50 + A980 NanoComplex — a thicker film that noticeably reduces oil escaping past the valve seals/rings and cuts consumption.
• No consumption / protection → 5 L Brava Extreme 9000 5W30 (PSA B71 2290 factory viscosity) + A980 NanoComplex.

The kit contains 5 litres (capacity ~4.2 L, with a reserve); that comfortably covers you between two oil changes.

How Does A980 NanoComplex Reduce Oil Consumption?

It strengthens the oil film and reduces oil escaping past worn valve seals and thin rings, cuts oil passage into the combustion chamber and noticeably reduces consumption. It also keeps the oil feeding the chain and turbo clean.

Which Motor Oil for the DS 4?

The PSA 1.6 THP requires a fully synthetic oil approved to PSA B71 2290; the factory viscosity is 5W30. If your car consumes oil, 5W50 is recommended (a thicker film); if it does not, 5W30. Both are offered in the kit as Brava Extreme 9000 fully synthetic.

DS 4 Oil Capacity

• Engine: 1.6 THP (EP6) — premium hatchback
• Oil capacity: ~4.2 L (with filter; may vary by engine code)
• Approval: PSA B71 2290 · Viscosity 5W30 (5W50 when consuming oil)
• Kit: 5 L Extreme 9000 + A980 NanoComplex 300 ml

DS 4 Oil Burning Symptoms

• Blue-grey smoke from the exhaust at idle / when pulling away
• A visible oil level drop every 500-1,500 km
• Chain rattle when cold
• Oil level/pressure warning, oil-fouled spark plugs

Other Common Problems of the DS 4

• Chain tensioner / chain stretch (the main chronic issue): On the EP6 THP there is a metallic rattle on cold start; the permanent fix is renewing the chain and tensioner, which is a job for an authorised service centre. Clean, correct oil extends chain life.
• Carbon build-up (direct injection): Carbon builds up behind the valves, causing idle/performance problems. A clean fuel system and additives help.
• Thermostat housing / water pump: Leaks from the plastic thermostat housing are common on the EP6 — the cooling system should be checked.
• High-pressure fuel pump / injectors: These can fail on direct injection; a clean fuel system extends their life.

Note: This kit targets the oil side of the DS 4 (consumption control + protection); mechanical repair of the chain or valve seals is a job for an authorised service centre.

Complete Maintenance and Additive Recommendation for the DS 4

Frequently Asked Questions

Why does the DS 4 burn oil?

On Prince 1.6 THP engines, worn valve stem seals and piston rings let oil into the combustion chamber; oil consumption is the known chronic problem of this family.

Which oil does the DS 4 use?

A fully synthetic oil approved to PSA B71 2290, factory fill 5W30. 5W50 if it consumes oil. The kit contains Brava Extreme 9000 (5W50/5W30) + A980.

What is the oil capacity of the DS 4?

Approximately 4.2 litres (with filter); the kit contains 5 litres (with a reserve).

Are the chain noise and oil burning on the DS 4 related?

Yes — dirty or low oil wears the chain tensioner. Clean oil in the correct viscosity + A980 both reduces consumption and protects the chain; advanced chain damage is a job for an authorised service centre.

Will this kit completely end oil burning on the DS 4?

Unless there is severe mechanical damage it reduces consumption substantially; if the valve seals/rings have deteriorated, service intervention is required.
