Low SAPS Oil (Low-Ash Oil)
Low SAPS oil contains reduced sulphated ash, phosphorus and sulphur to protect particulate filters and catalytic converters.
What is Low SAPS Oil (Low-Ash Oil)?
ACEA C classes are low or mid SAPS oils. It is required for most modern diesels with a DPF. Many petrol cars with particulate filters also need it. Using the correct low-SAPS oil also helps protect catalytic converters from phosphorus poisoning.
How it works
Fewer metal-based additives mean less ash builds up in the filter, which cannot be burnt off.
Why it matters for your car
Using high-ash oil shortens DPF life. Follow the manual’s specification.
