Opel Astra Oil Burning & Oil Consumption Prevention Kit (1.4 Turbo)

Opel Astra 1.4 Turbo Oil Burning and Oil Consumption Problem

The 1.4 Turbo (A14NET) engine of the Opel Astra (Astra J (2009-2015) and Astra K (2015-2019) 1.4 Turbo) is known for oil consumption; it can reach 0.6 litres per 1,000 km. On most cars the main cause is a fault in the crankcase ventilation (PCV) system together with oil leaks from the turbo and its seals. The correct viscosity and clean oil are critical in bringing consumption under control.

Oil Burning Prevention Kit for the Opel Astra

• Astra that consumes oil → 4 L Brava Extreme 9000 5W50 + A980 NanoComplex — a thicker film that noticeably reduces consumption.
• No consumption / protection → 4 L Brava Extreme 9000 5W30 (dexos2 viscosity) + A980 NanoComplex.

How Does A980 NanoComplex Reduce Oil Consumption?

It strengthens the oil film and reduces leakage around the rings and seals, cuts oil passage into the combustion chamber and noticeably reduces consumption, while protecting the turbo.

Which Motor Oil for the Opel Astra?

The 1.4 Turbo requires a fully synthetic oil of the dexos2 / 5W30 class. If your car consumes oil, 5W50 is recommended; if it does not, 5W30. Both are offered in the kit as Brava Extreme 9000 fully synthetic.

Opel Astra Oil Capacity

• Engine: 1.4 Turbo (A14NET)
• Oil capacity: ~4.0 L (service fill ~3.5 L)
• Kit: 4 L Extreme 9000 + A980 NanoComplex 300 ml

Opel Astra Oil Burning Symptoms

• Blue/grey smoke from the exhaust
• Frequent oil top-ups, a low oil pressure warning
• A whistle/noise from the turbo
• Rough idle caused by the PCV

Other Common Problems of the Opel Astra 1.4 Turbo

• Crankcase ventilation (PCV/CGV) failure: The main problem seen on almost every A14NET engine; when the PCV diaphragm fails, oil is drawn into the combustion chamber, oil consumption rises and a low oil pressure warning may appear. Renewing the valve cover/PCV is a job for an authorised service centre; the correct oil and A980 reduce consumption.
• Turbo actuator / seal leak: The turbo bypass actuator spring weakens over time and oil can leak from the seal. Clean oil in the correct viscosity protects the turbo.
• Note: the timing chain on this engine is reliable — the real oil consumption comes from the PCV and the turbo.

Note: This kit targets the oil side of the Opel Astra; PCV/valve cover and turbo work is a job for an authorised service centre.

Frequently Asked Questions

Why does the Opel Astra burn oil?

Most often a crankcase ventilation (PCV) failure and a turbo/seal leak; oil is drawn into the combustion chamber. The correct viscosity + A980 reduces consumption.

Which oil does the Opel Astra use?

A dexos2 / 5W30 fully synthetic oil; 5W50 if it consumes oil. The kit contains Brava Extreme 9000 (5W50/5W30) + A980.

What is the oil capacity of the Opel Astra?

Approximately 4.0 litres (service fill ~3.5 L); the kit contains 4 litres.

Why does the low oil pressure warning come on in the Opel Astra?

Usually because of a PCV failure and a level drop caused by oil consumption; have the level and the PCV checked. The correct oil matters.

Will this kit stop oil burning on the Opel Astra?

A980 + the correct viscosity noticeably reduces consumption; unless there is a mechanical PCV/turbo fault, most cars come close to normal.
