What is a Diesel Particulate Filter and why does it effect the engine oil requirement for my engine?


A Diesel Particulate Filter (DPF) is an emmission control device fitted to the exhaust stream of some modern diesel engines. It traps any soot that is present in the exhaust gases. All engines allow some amount of engine oil into the combustion chamber through cylinder lubrication, breathers etc. This oil is burnt and enters the exhaust stream. It is important to use oils with the correct levels of additive to prevent blockage of the DPF. Lows SAPS oils are generally recommended for DPF fitted vehicles. Consult your vehicle handbook or the Nulon Lube Guide (mobile version) for correct oil selection.
