DTFR 13C140

DTFR 13C140 is an approved DAF Trucks technical specification for lubricants, intended exclusively for their medium‑ and heavy‑duty turbo diesel engines. The specification requires a base viscosity of SAE 15W‑40, high oxidation stability (TBN ≥ 12 mg KOH/g), effective soot dispersion and low SAPS content, which ensures safe operation of after‑treatment emission systems DPF and SCR without damaging the catalyst. Additionally, DTFR 13C140 guarantees wear protection under high loads, maintenance of oil pressure under high torque, and support for fuel economy in continuous operation conditions. The specification is a direct continuation of the previously approved DTFR 13C120/13C130, so lubricants that meet those older requirements are generally compatible, but the optimal choice remains products labeled DTFR 13C140. When selecting oil on xenum.ua, the “DTFR” filter quickly shows all five products that have passed this approval, providing long‑lasting engine and emission system protection in DAF trucks.
