What the AI looks for in Hydraulic Oils

ISO viscosity grade: Match the specified ISO VG. 32, 46 and 68 are the most common, with 32 often used in cold climates and 68 in hot or high-load conditions. The wrong viscosity affects pump efficiency, wear and how sluggish the system is in cold weather.
Anti-wear type: Choose AW (anti-wear) hydraulic oil for most gear and vane pump systems, unless the equipment calls for an R&O or zinc-free fluid. Pump makers specify additive chemistry, and some systems need zinc-free or ashless fluid.
Tractor or wet-brake systems: Use a universal tractor hydraulic fluid (UTTO) that meets the OEM spec, such as John Deere J20C or Hy-Gard, when the hydraulics share oil with the transmission and wet brakes. Plain AW hydraulic oil lacks the friction properties for wet brakes and clutches and causes chatter.
Multigrade for outdoor use: Choose a high-viscosity-index (HV) fluid for equipment that works across wide temperature swings. High-VI fluid keeps response consistent from cold starts to full operating heat.
Jacks and lifts: Use hydraulic jack oil or the specified AW grade. Never use brake fluid or motor oil. Brake fluid attacks the seals in jacks and lifts.

Mobil DTE: Widely specified AW industrial hydraulic oil range.
Chevron Rando: Common anti-wear hydraulic oil line in ISO grades.
Shell Tellus: Industrial hydraulic oil range in standard ISO grades.
John Deere Hy-Gard: OEM tractor hydraulic and transmission fluid for shared-sump equipment.
Valvoline: Retail-available AW hydraulic oils and UTTO fluids.

AW means the oil contains anti-wear additives, and 32 is the ISO viscosity grade. Both need to match the equipment spec.
