Volvo 1161540

Volvo 1161540 is a technical approval from the Volvo Group for automatic transmissions, defining requirements for viscosity, thermal stability, oxidation resistance and wear protection. A fluid meeting this standard provides stable friction behavior over a temperature range from –40 °C to +120 °C, retains its properties under high load and prevents deposit formation in valve components. The specification is targeted at Volvo automatic gearboxes VCC, VDS‑3/4/4.5 installed in passenger, commercial and hybrid models, including diesel units with DPF, where compatibility with after‑treatment catalysts is important. Products marked Volvo 1161540 also meet the previous Volvo 97308‑97310 requirements, allowing their safe use in older models without loss of warranty coverage.
