Oil Capacity

Why engine oil capacity varies so much

Oil capacity is the volume of engine oil a specific engine holds, and it is a property of the engine, not of the badge on the car. A single model year of one model can span three or four engines with capacities that differ by more than two litres. Getting it wrong in either direction causes real damage, which is why the figure belongs in the service record rather than in memory.

Two numbers are published for most engines and they are not interchangeable:

• With filter change — the volume needed after draining the sump and fitting a new filter. This is the figure that matters at a normal service.
• Without filter change — drain and refill only. Lower, because the filter and its housing retain oil.

Capacity is not the same as specification

Capacity tells you how much. Two further things tell you what:

• Viscosity grade such as 0W-20 or 5W-30, chosen by the manufacturer for the bearing clearances and the oil pump in that engine.
• Approval or standard such as an API service category, an ACEA sequence, or a manufacturer-specific approval. Modern engines with particulate filters or long service intervals often require a specific approval, and a bottle that merely lists a viscosity may not carry it.

Pouring the right quantity of the wrong specification is still the wrong oil change.

Overfilling and underfilling

Underfilling starves the pump at high load and on sustained cornering. Overfilling is the more common workshop error and is not harmless: the crankshaft can whip the oil into foam, foam does not carry load, and the excess pressure pushes oil past seals and into the intake through the crankcase ventilation system. On engines with a particulate filter, oil drawn into the exhaust stream shortens filter life.

How to verify before you pour

• Identify the engine, not just the model. The engine code is usually on the block, on a sticker under the bonnet, or decodable from the VIN.
• Fill to roughly 80 percent of the published capacity, run the engine briefly, let it settle, then top up to the mark on the dipstick or by the electronic gauge.
• Check the level on level ground and at the temperature the manufacturer specifies. A reading taken immediately after shutdown on a slope means nothing.
• On engines with no dipstick, follow the vehicle procedure exactly. The electronic measurement is valid only under the conditions it was calibrated for.

What these pages contain

Each model-year page below lists the oil capacity figures we hold for that vehicle, separated by engine where the manufacturer publishes separate values, with the with-filter and without-filter distinction preserved rather than collapsed into one number. Sourcing and correction handling are set out in our methodology and editorial policy.

Treat these figures as a cross-check against your owner manual and the service documentation for your market. Where they disagree, follow the manufacturer document for your vehicle and tell us through the contact page so we can review the record.
