DL-1

JASO DL‑1 is a Japanese technical standard that defines the requirements for motor oils for passenger car diesel engines aimed at low emissions. Oils that meet DL‑1 must have a low content of sulfate, aromatic and phosphorus compounds (SAPS), provide high detergency, oxidation resistance and an excellent viscosity index, which guarantees stable operation over a wide temperature range. The specification provides compatibility with after‑treatment emission systems, in particular particulate filters (DPF) and catalysts, preventing their clogging. Therefore, DL‑1 is suitable for modern passenger‑car diesel engines, including turbocharged and direct‑injection models, as well as for some hybrid diesel power units that require low‑ash lubricants. When selecting oil on xenum.ua, the JASO DL‑1 label helps quickly find a product that meets these requirements, such as the synthetic XENUM PRO‑F 5W30.
