Always check the OEM spec first. ISO 46 is the most common grade for mobile equipment; ISO 32 suits cold climates and lighter systems; ISO 68 is for hot industrial duty.
| ISO Grade | Typical Equipment | AMSOIL Product |
|---|---|---|
| ISO 22 | Cold-climate mobile equipment, log splitters, low-pressure systems | AWG / HVG |
| ISO 32 | Mobile hydraulics, scissor lifts, lighter mobile equipment | AWH / HVH / HCG32 |
| ISO 46 | Excavators, skid steers, dump trucks, industrial presses (most common) | AWI / HVI / HCG46 / BHO (biodegradable) |
| ISO 68 | Hot-climate industrial presses, injection molding, sawmills, stationary power | HVJ / HCG68 |
| Tractor UTTO | Tractors, combines, ag equipment with shared hydraulic/transmission sump | ATH / TCGSB |
Hydraulic fluid powers nearly every industry that lifts, pushes, digs, or presses. AMSOIL synthetic hydraulic oil ships nationwide to operators in:
Tractors, combines, balers, sprayers, manure spreaders. Use ATH Tractor UTTO for shared-sump equipment.
Excavators, skid steers, backhoes, telehandlers, wheel loaders. ISO 46 (AWI) is the workhorse grade.
Hydraulic presses, injection molding machines, machine tools, automation. ISO 46 or ISO 68 depending on temperature.
Log splitters, skidders, processors, chippers. BHO biodegradable hydraulic oil for environmentally-sensitive sites.
Dump trucks, garbage packers, snow plows, street sweepers, bucket trucks. Long-drain AWI cuts service stops.
Wreckers, dump trailers, hooklift trucks, liftgates. Synthetic stays in grade through hot summer duty.
AMSOIL Synthetic Anti-Wear Hydraulic Oil is engineered for service intervals up to 12,000 hours — approximately 6x longer than conventional anti-wear hydraulic oil. Actual life depends on filtration quality, contamination, and operating temperature; pair with high-efficiency filters and periodic oil analysis to maximize uptime.
Yes — synthetic hydraulic oil delivers superior shear stability, oxidation resistance, low-temperature fluidity, and wear protection. That translates to longer drain intervals, less pump and valve wear, less varnish, and reliable cold starts on excavators, skid steers, and tractors that run year-round.
ISO viscosity grade 46 is the sweet spot for the vast majority of mobile equipment — excavators, skid steers, dump trucks, telehandlers, and industrial presses. It pumps reliably at cold start, holds film strength at full operating temperature, and stays in grade under the high-pressure shearing inside piston pumps. AMSOIL AWI ISO 46 covers most of these applications with a single bottle.
If your equipment operates in or near waterways, forests, farmland, or municipal areas, AMSOIL Biodegradable Hydraulic Oil (BHO) protects against the cost and liability of a hydraulic leak. It meets EPA Vessel General Permit (VGP) requirements as an Environmentally Acceptable Lubricant and biodegrades per OECD 301B — without sacrificing the wear protection or service life of a premium synthetic.
Most modern tractors share a single reservoir for hydraulics, transmission, wet brakes, and PTO. AMSOIL Synthetic Tractor Hydraulic/Transmission Oil (ATH) is a Universal Tractor Transmission Oil (UTTO) that meets John Deere J20C/D, Case MS 1207/1209/1210, New Holland 134D, and Kubota UDT specifications — one bottle for the whole fleet.
