  • Rapid biodegradation rate
  • Certified carbon neutral footprint
  • Matches petroleum fluid performance


  • Triple the price of standard fluids

If your landscape equipment operations prioritize eco-friendly credentials, Bio Universal deserves a close look as an environmentally conscious substitute for Toro transmissions and hydraulics. Its unique vegetable oil base fluid achieves impressive sustainability targets without compromising hydraulic system protection abilities.

Being three times more expensive than conventional mineral oils keeps overall running costs high though. Castrol Bio Universal makes most sense for commercial operators invested in maximizing green principles across their fleet.

Phillips 66 Hydraulic Oil AW

Phillips 66 Hydraulic Oils AW are budget-friendly anti-wear hydraulic fluids intended for standard stationary and mobile hydraulic system applications – not specialized transmission duties like Toro’s. But they offer reliable protection when operating conditions aren’t overly demanding.


Phillips 66 Hydraulic Oil AW
  • Most affordable price tier
  • Good viscosity range choices
  • Meets minimum anti-wear standards
  • Acceptable oxidation resistance


  • Much lower performance ceilings
  • Shorter fluid life than premium oils

Due to more basic formulations focused on affordability over performance extremes, Phillips 66 HO AW fluids cap out at moderate protection abilities and fluid change intervals compared to Toro HYPR-OIL 500.

But for lighter household mowing use or seasonal commercial landscaping fleet duties, they offer “good enough” shielding for hydraulics at the most attractive per-gallon pricing among major hydraulic oil brands, while carrying major manufacturer approvals.

Cam2 Pro Max Hydro Toro

A niche player in the hydraulic fluid space, Cam2 offers its Pro Max Hydro Toro premium hydraulic oil range specifically designed to meet or exceed Toro’s HYPR-OIL 500 performance specifications – at around half the price.

FAQ on Toro Hydraulic Fluid Specs

To close out this guide, here’s more detail around Toro equipment hydraulic fluid technical specifications in case you need to cross-reference fluids mentioned above or confirm alternate hydraulic oil grades:

What Specific Grades Can Substitute Toro HYPR-OIL 500?

Toro HYPR-OIL 500 hydraulic fluid has an ISO 46 anti-wear hydraulic oil viscosity grade with operating temperatures ranging around -26°C to 98°C when used in Toro hydrostatic transmissions.
Any hydraulic fluid substitutes should fall within a +/- one viscosity grade to best match system specifications – so ISO 32, 46 or 68 grades that show hydrostatic transmission approval meet the viscosity criteria.
Toro also offers HYPR-OIL 600 for certain products, which is an ISO 68 hydraulic oil grade.

Do All Toro Models Use HYPR-OIL 500 for Hydraulics?

Most major Toro commercial and residential mowers, compact utility loaders, trenchers and turf renovation equipment with hydrostatic transmissions use Toro’s specially formulated HYPR-OIL 500 hydraulic fluid as factory fill during manufacturing.
But some entry residential products may allow regular ISO 46 hydraulic oils since hydraulic system pressures and stress factors are lower. Always consult specific operator’s manuals to confirm approved fluids for your Toro landscape machine.

What About Gasoline-Powered Toro Dingo Models – Can They Substitute?

Unlike diesel-powered Toro Dingo compact utility loaders requiring HYPR-OIL 500 for their hydraulic reservoirs, gasoline-powered Dingo models use the engine’s motor oil for their hydrostatic drive systems in order to simplify maintenance.
So gasoline Dingos filled from the factory with standard 10W-30 or 5W-30 conventional motor oils don’t need HYPR-OIL 500 substitutes – just stick with the same viscosity grade engine oil during fluid changes.

Will Using Non-Approved Fluids Void Toro Equipment Warranties?

While Toro doesn’t explicitly void warranties if non-OEM fluids are used in their landscape equipment, they do “highly recommend” factory-fill fluids like HYPR-OIL 500 or approved substitutions to “best protect Toro products and maximize performance.”
So while you can get away with substitute hydraulic oils, Toro hints that equipment issues arising later related to inferior fluid performance likely won’t be covered by warranty terms. Stick to prescribed factory fluids when possible.

Closing Remarks

Hopefully these further Toro hydraulic fluid usage details help reinforce the optimal fluid options uncovered above for keeping your landscape equipment’s demanding hydrostatic systems performing reliably long term.
