Hydraulic oil for excavator | Heavy Equipment Forums

Sep 26, 2012 · ISO VG32 hydraulic oil is actually quite a bit lighter than an SAE 10W "engine grade" hydraulic oil. In reality a 10W oil (with a viscosity of around 42 cSt) is actually much closer to an ISO 46 hydraulic oil than a 32. I would say a 10W hydraulic oil for preference, it's what the factory recommends. For top-ups an ISO 46 oil would be the best

How to solve hydraulic system overheating problems

Hydraulic oil temperatures above 180°F (82°C) damage most seal compounds and accelerate degradation of the oil. While the operation of any hydraulic system at temperatures above 180°F should be avoided, oil temperature is too high when viscosity falls below the optimum value for the hydraulic system's components.
