Bobcat machinery is built tough, but it relies heavily on one crucial fluid: hydraulic oil. Choosing the right hydraulic oil keeps your equipment running strong and safely. In this guide, we’ll dive into the Bobcat hydraulic oil equivalent chart, offering comparisons, specs, and trusted alternatives to save you time and money without risking performance.

How to Choose the Right Hydraulic Oil
Consider these key points:
- Match the ISO viscosity (usually ISO 46 for Bobcat)
- Check your machine manual for OEM specs
- Consider operating temperatures
- Evaluate synthetic vs mineral oil needs
Hydraulic Oil Viscosity Explained
Viscosity is how thick or thin a fluid is. Most Bobcat machines use ISO VG 46, a mid-weight oil suitable for most climates. Using the wrong viscosity can damage pumps and hydraulic components.

Top Factors to Consider Before Replacing Oil
- Machine Age – Older units may benefit from synthetic oil.
- Usage Frequency – Heavily used machines need high-resistance oil.
- Weather Conditions – Use low pour point oil in freezing temperatures.
- Brand Compatibility – Always use fluids that meet or exceed Bobcat specs.
Tips for Hydraulic Oil Maintenance
- Check oil levels weekly
- Inspect for leaks regularly
- Replace filters on the schedule
- Avoid mixing brands unless confirmed compatible
- Store oil in a dry, clean area

FAQ
What hydraulic fluid is compatible with Bobcat?
Bobcat machines typically require ISO VG 46 hydraulic oil, also known as AW46 or ISO 46. Compatible alternatives must meet or exceed Bobcat’s OEM specifications. Reputable equivalents include:
- Mobil DTE 25
- Shell Tellus S2 M 46
- Chevron Rando HDZ 46
- Valvoline AW 46
- Amsoil ATH Synthetic Hydraulic Oil

Can you use AW46 in a Bobcat?
Yes, AW46 (Anti-Wear 46) hydraulic oil is compatible with most Bobcat equipment, particularly if your machine calls for ISO VG 46 fluid. AW46 offers:
- Excellent anti-wear protection
- Oxidation stability
- Good performance in moderate temperature conditions
Just make sure the oil brand you choose meets Bobcat’s performance specifications.
What is ISO 46 equivalent to hydraulic oil?
ISO 46 is a viscosity grade for hydraulic oil defined by the International Standards Organization (ISO). It’s equivalent to:
- AW46 hydraulic oil (common North American label)
- Mid-range thickness oil suitable for temperatures between -20°F to 120°F
- Ideal for systems like loaders, excavators, and backhoes
So, ISO 46 = AW46, as long as they meet the anti-wear and oxidation resistance standards.
What is the number for Bobcat hydraulic oil?
Bobcat hydraulic oils are often identified by names like:
- HT100 (OEM synthetic blend)
- Bobcat Hydraulic/Hydrostatic Fluid
- Bobcat part numbers may include:
- #6903117 – Bobcat HT100
- #7334046 – Hydraulic/Hydrostatic Fluid
Always use part numbers from your Bobcat dealer or manual to order exact fluids.
What is the best oil for a Bobcat?
The best oil depends on your machine’s usage and climate:
- HT100 or Mobil DTE 25 – Great for general use
- Shell Tellus S3 V 46 – Excellent for variable temperatures
- Amsoil ATH – Best for all-weather and heavy-duty applications
- BioFlo AW 46 – For environmentally sensitive areas
In short, look for ISO VG 46 hydraulic oils that meet Bobcat OEM specifications.
Is ATF compatible with hydraulic fluid?
No, ATF (Automatic Transmission Fluid) is not a recommended replacement for hydraulic oil in Bobcat machines. While both are lubricants:
- ATF has different additive packages
- Viscosity levels and detergents differ
- It can cause seal wear, foam, or overheating
Only use ATF if the manufacturer specifically permits it (which Bobcat does not for most equipment).
