Bought a new log splitter? Or using a log splitter for a while? Either way, here is what you need to know about Log Splitter Hydraulic Fluid Change, which is the key performer.
If you want your log splitter to keep splitting for many years to come, do check the hydraulic fuel regularly.
How often should you change the hydraulic fluid? Whether it’s gas or electric log splitter, it is recommended to change the hydraulic fluid every 100 hours of work. You need to change the log splitter hydraulic oil filter in addition.
Before moving forward, let’s make things clear. What does hydraulic fluid do in a log splitter?
Yes, this question is very common. Hydraulic fluid is the main power transfer source in a log splitter. Hydraulic log splitters depend on the power/pressure generated by the hydraulic fluid to push the wedge.
A motor is used for pumping the hydraulic fluid and the fluid gets pressurized as it is concealed in a hollow fluid pipe and cylinder. This pressure moves log against the piston.
I’ve written an in-depth article reviewing the best log splitter you can get. Read that if you are thinking for an upgrade.
Kind of Hydraulic Fluids Used in a Log Splitter:
Log splitters can use a different number of hydraulic fluids in their operation. However, you should use the oil recommended by the manufacturer. Using the recommended fluid is the best way to avoid damage to your log splitter.
- Non-Flammable: This fluid is considered non-flammable and this comprises of some natural chemicals that will not form a foam. An absence of foam in the hydraulic system while operation means no dirt build-up.
- Flammable: This oil-based fluid gives more power to the hydraulic system. This helps to prevent corrosion but leaves sticky build ups behind.
- Synthetic fluid: This type of fluids are man-made chemical compositions. These are completely non-flammable too. However this type of log splitter hydraulic fluid is responsible for corrosion.

Changing Hydraulic Fluid of Log Splitter
- First of all, place a suitable container under the fluid reservoir to collect the fluid. Splitting oils on the ground is not a good practice.
- Then disconnect the suction hose pipe from the bottom of the fluid reservoir tank. See your manual that came with your log splitter.
- Carefully remove the inlet filter and clean it.
- Unscrew the drain plug. Let the fluid to drain into the suitable container. A hydraulic reservoir tank can have a capacity of 3 gallons and the entire hydraulic system can sustain up to 4.7 gallons of fluid. So make sure the container is a big one.
- Now, the main part. Adding hydraulic fluid to log splitter. Place a funnel in the fill tube and add the desired amount of 10W AW hydraulic fluid to the reservoir. Check the fluid level using the dipstick. Do not overfill.
- If necessary replace the filter and the dipstick. Re-install the filter, dipstick. Tighten the drain plug and screw of the fill tube.
- To help to remove trapped air from the system, engage the wedge with the control handle and move it back and forth several times.
- If necessary, refill the reservoir up to the mark on the dipstick.
Changing Engine Oil of Hydraulic Log Splitter
- Place an oil pan under the engine drain plug.
- Remember to cool down the engine for your safety. This article covers all those.
- Unscrew the drain plug. Let the oil drain from the engine.
- Remove the dipstick. This will help the oil drain faster.
- Replace the drain plug once the fluid is drained from the reservoir.
- Place a funnel in the dipstick hole and fill the reservoir with 10W-30 motor oil. Do not overfill the reservoir.
- Finally, remove the funnel. Check the level of oil. Lock the dipstick in place.

What hydraulic oil do you recommend for log splitters???
This is the most common question that anyone can think using a log splitter. Should I use this or that? Yes, I know there is some good number of log splitter hydraulic oil available on the market. Among them, I have chosen the best one for you.
- Great Value for money
- Virgin Paraffin based hydraulic oil: Great for the system
- 2.5-gallon saver pack
- Has anti-wear protection to save your log splitter cylinder
- Lightweight. Comfortable for log splitter
What is AW 32 Oil?
AW hydraulic oil is a premium grade oil that is designed for use in hydraulic systems. Especially, the systems where anti-wear hydraulic oil is recommended. 32 is an ISO grade.
What is the Difference Between AW 32 and AW 46 Hydraulic Oil?
There is no technical difference between these two except viscosity. There are no good or worse. AW 32 is preferred in log splitter due to the less viscosity over AW46. AW 32 will flow better than AW 46 in cold weather.
Our Recommendation For Log Splitter Hydraulic Filter???
A log splitter hydraulic oil filter is used to filter out the sediments. Sediments can settle down and stick with the hydraulic fluid chamber. This sticky build-up is really harmful to the hydraulic system. That’s why a good oil filter is mandatory. Let’s get a good oil filter here!
- Removes harmful contaminants
- Almost perfect fit for many log splitters
- Most noteworthy is its long-lasting feature
Things You Should Know Before Hydraulic Fluid Change
• A good amount of fluid is drawn into the cylinder and hoses. So, always remember to fill the reservoir. A hydraulic pump should be kept with a filled reservoir. An empty hydraulic pump will lead to damage. This may break the warranty condition.
• Never overfill hydraulic or motor oil. These fluids may overflow due to the heat generated by the system according to the law of fluid expansion. This is how the fluid mechanism works. Hence, never operate the machine without a proper amount of fluid level.
• Whenever you check the fluid level remember to properly tighten the dipstick to prevent leakage or air trapping most of all.
• Do not dispose of used hydraulic or engine oils in the open environment.
• Most noteworthy: Avoid contamination in the fluid at any cost. Contamination can lead to hydraulic system damage or engine corrosion. In conclusion, flush the reservoir or engine pistons with kerosene while servicing.
Log splitter hydraulic fluid change is crucial for a log splitter. So, choose wisely. I have written a guide on the maintenance of log splitter leaking hydraulic fluid.
