Diesel vehicles with diesel particulate filter (DPF)
For diesel cars fitted with a DPF it may be essential to use one of the latest 'low SAPS' (Lower levels of Sulphated Ash, Phosphorous and Sulphur) motor oils. 

C1 Low SAPS (0.5% ash)  catalyst compatible in vehicles with DPF and TWC. Also fuel efficient
C2 Mid SAPS (0.8% ash)   catalyst compatible in vehicles with DPF and TWC. Also fuel efficient
C3 Mid SAPS (0.8% ash)   catalyst compatible in vehicles with DPF and TWC.
C4 Low SAPS (0.5% ash)  catalyst compatible in vehicles with DPF and TWC.

WARNING:- These oils are unsuitable for use in some engines. Always consult the vehicle handbook.

DPF;- Diesel Particulate Filter
TWC:- Three way catalyst

Always consult the vehicle handbook

The vehicle handbook includes information about the specification of engine oil  suitable for your engine.
ACEA/API specifications are marked clearly on the oil container label.

Where a manufacturer's own specification is quoted in the handbook then you must look for this on the oil container label. In some cases manufacturers will specify an acceptable equivalent ACEA or API specification too. This might be for 'emergency top-up only.
