DEUTZ DQC III-18 LA

DEUTZ DQC III‑18 LA approval defines a motor oil with a viscosity equivalent to SAE 10W‑40/15W‑40, providing stable operation at high temperatures and wear protection in heavy-duty diesel engines. The III designation indicates compliance with medium load and torque requirements, and the number 18 denotes a base viscosity of 180 cSt at 100 °C, suitable for trucks, agricultural machinery and generator sets. The letter designation LA stands for “Low Ash”, i.e., a low content of sulfate, aromatic and phosphorus compounds, making the oil compatible with exhaust after‑treatment systems (DPF, catalysts) and allowing operation under standards E9‑E11. Oils approved to DQC III‑18 LA meet the requirements for oxidation stability and corrosion protection, extending engine service life and reducing fuel consumption. On xenum.ua you will find XENUM DIESEL POWER 10W40 and 15W40 products, which fully comply with this standard and can replace oils with previous DQC III‑18 approvals without LA.
