CAN I MIX HYDRAULIC FLUIDS? As far as possible, it is always best to avoid mixing different hydraulic fluids. This is because the technical properties could be spoiled by chemical reactions between different additives.
Key difference between hydraulic fluid & hydraulic oil is that hydraulic fluid consists of various kinds of fluid such as water-oil emulsion, salt solutions or even plain water. Hydraulic oil is also a fluid but used, for example, in car’s braking system and power steering system.
Most are compatible, but if they aren’t, you risk ruining every rubber part in the system (o-rings, rod seals, shaft seals, etc) In general, no, do not mix hydraulic fluids. There are various seal materials and there are some fluids which will attack some seal materials.
Therefore, the mixing of hydraulic oils with differing water separation characteristics may cause a reduction in emulsification characteristics or eliminate these characteristics altogether, thereby causing undesirable operating conditions.
What happens if you mix hydraulic oils?
“Is it all right to mix an R&O hydraulic oil with an AW hydraulic oil in a hydraulic application?” Mixing oils with different additive packages is never recommended. Doing so could compromise the additive performance of both constituents, cause corrosion of component surfaces and lead to increased mechanical wear.
Is hydraulic oil different than hydraulic fluid?
Hydraulic oil is a non-compressible fluid that is used to transfer power within hydraulic machinery and equipment. Otherwise known as hydraulic fluid, hydraulic oil can be synthetic- or mineral-based.
Are all hydraulic fluids compatible?
Most hydraulic systems can operate using many different fluids, including multigrade engine oil, automatic transmission fluid and more conventional antiwear (AW) hydraulic oil. Which oil or fluid you choose depends on your equipment and how you plan to use it.
Can you mix ISO 32 and ISO 46 hydraulic oil?
Yes as above no problems mixing them.
Can synthetic and regular hydraulic oil mix?
Mixing oils with different additive packages is never recommended. Doing so could compromise the additive performance of both constituents, cause corrosion of component surfaces and lead to increased mechanical wear.
Can you mix synthetic and non synthetic hydraulic oil?
So, in the end, conventional and synthetic oils are comprised of the same, compatible components – it’s just that the components in synthetics are much higher quality. While you can safely mix synthetic and conventional oils, you’re doing nothing more than diluting the performance of the synthetic oil.
Are all hydraulic oils compatible?
Although new hydraulic fluids may be compatible, in-service fluid of the same type may be degraded or contaminated to such an extent that the new fluid added may not be compatible with the system fluid.
What happens if you use the wrong hydraulic fluid?
Whether it is changing hydraulic filters too often or using the wrong type of hydraulic fluid, these errors can lead to serious problems such as unnecessary maintenance costs, increased repair costs, system downtime, premature wear of components, and even catastrophic failure.
Is gear oil and hydraulic oil the same?
Gear oil and hydraulic oil are two different fluids that come under the category of lubricants. The formulation of these lubricating oils varies significantly according to their applications in equipment.
Can you mix transmission fluid with gear oil?
Whilst some manual gearboxes do use transmission fluids in place of gear oil, the same cannot be said for putting gear oil into an automatic transmission. Gear oil is much too viscous for these systems and will cause clogging between components.
What happens if you mix gear oils?
Mineral oils, PAOs and esters may all be mixed together. Only polyglycol type synthetic oils (PG or PAG) may not be mixed with the other lubricant types. They can react together and form gum gels in the casings. Furthermore, they can sometimes be incompatible and immiscible with other polyglycols.
Can I use regular oil for hydraulic oil?
Engine oil can work satisfactorily as a hydraulic fluid. However, if a multigrade engine oil is being used in the hydraulic system specifically for its high viscosity index (VI), then it’s not the correct solution. The reason is the additives used to improve viscosity index.
More Answers On Can You Mix Hydraulic Oil And Hydraulic Fluid
In a hydraulic system, can I mix two hydraulic oils in a tank?
All will mix, but motor oil is made to absorb moisture and take it to hot places where it will evaporate instead of puddle or bubble. Most industrial hydraulic oils are made do separate the water and drop it to the bottom of the tank so it can be drained. You will end up with a mixture of those two characteristics, not wanting to do either.
Understanding Hydraulic Oil Compatibility – Machinery Lubrication
As a result, the mixing of hydraulic oils with different anti‑foam agents may actually increase the foaming of the oil. Some hydraulic oils may be blended to allow water to mix or emulsify with the oil. On the other hand, some oils are formulated to ensure that the water separates from the oil.

Jun 3, 2022When you use a metal working fluid, you can mix ISO 46 and 68 hydraulic oil. These grades are similar to SAE 20 weight lubricants, but with different viscosity characteristics. The difference between them is in the degree of viscosity and the thickness of the fluid. For this reason, ISO 46 and 68 hydraulic oil are often interchangeable.
mixing hydraulic fluid? – Heavy Equipment Forums
I too just recently purchased a J.D. 250. I was at the dealer today, and the guy at the parts counter told me, that they recommend a /15w40 for hydraulic fluid.
