Toro Dingo Hydraulic Oil for Toro models TX220, TX320, TX427, TX525 and TX-1000 Dingo's. Toro’s hydraulic oil recommendation for your Dingo changed in 2011. This was necessary due to a change in the formulation for the latest diesel motor oil API specification, CJ-4. It has a reduced amount of ZDDP anti-wear additive and no longer meets the hydraulic system requirements. Please review the Hydro Oil Chart for your Dingo
