With all those brands on the shelf, hydraulic fluid might well seem like a matter of preference. To a degree, it is. You may not actually need the brand that’s specified on your equipment, so long as the fluid you choose is up to spec with your machinery’s needs.
However, the lubricants and fluids you choose must also come down to performance, uptime, and protecting the investment you’ve made in your heavy equipment. The qualities and capabilities of the fluid will play a direct role in how well your equipment runs and how often it needs repair. This is going to be true whether you’re running excavators on a construction site, maintaining a municipal fleet, or operating harvesters in the field.
How Hydraulic Fluid Selection Impacts Your Vehicle
At their most basic functional level, hydraulic fluids transfer power. That’s their purpose. However, they also lubricate components, manage heat, and protect against rust and oxidation. A sub-optimal type for your vehicle or use case can shorten the lifespan of expensive equipment or result in unnecessary maintenance and lost time and money.
On the flip side, a well-matched hydraulic fluid helps to:
- Reduce friction and wear on pumps, valves, and motors
- Prevent component failure caused by contamination or thermal breakdown
- Maximize performance under load and in changing temperatures
- Extend service intervals and lower total cost of ownership
For those managing large fleets or heavy workloads, the right fluid spec can add up to big savings.
4 Things to Consider When Choosing Hydraulic Fluids
There’s no single one-size-fits-all guideline for comparing your options. Things like equipment type, operating environment, OEM specs, and budget will all play a role. Here are some key considerations our lubrication expert walks through with every customer:
1. OEM Requirements vs. Local Availability
Many operators think they need the exact brand listed on the equipment manual. But in most cases, you don’t. We can often match your spec with an equivalent fluid from Chevron or another top brand that’s in stock at our warehouse. That means less time waiting on shipments and fewer headaches when you're servicing 40 or 50 machines at once.
2. Viscosity and Temperature Range
Work in freezing mornings and scorching afternoons? You’ll need a fluid with the right viscosity index to stay stable under those temperature swings. Thicker isn’t always better—our team helps you dial in the right balance for your conditions.
3. Anti-Wear and Oxidation Resistance
Higher-pressure systems and longer service intervals demand high-quality additives. AW (anti-wear) hydraulic oils with strong oxidation resistance can protect your systems over the long haul. We recommend top-tier fluids that meet or exceed major OEM standards.
4. Compatibility With Other Lubricants
Switching fluids? Be careful. Not all products mix well. Our CLS can walk your team through proper procedures and product compatibility to avoid costly contamination issues during changeouts.
