The KX033-4 uses the Kubota D1703M-DI-E4 diesel engine, a 1.647-liter three-cylinder engine producing approximately 24.8 gross horsepower at 2,200 rpm.
Kubota KX033 4 Engine Oil Capacity
The Kubota KX033-4 engine oil capacity is 5.3 liters (1.4 US gallons), including the oil filter. The KX033-4 is powered by a Kubota D1703M-DI-E4 1.647-liter, 3-cylinder diesel engine.

Kubota’s official KX033-4 information lists the engine as the D1703M-DI-E4, with 1,647 cc displacement and 24.8 gross horsepower. Kubota’s fluid-capacity information also confirms the 5.3-liter engine oil capacity.
For an oil change, it is useful to have at least 6 liters of suitable engine oil available. However, do not simply pour the entire amount into the engine without checking the dipstick. Add the oil gradually and verify the level after the engine has been run briefly and then shut down.
The actual amount required during a routine service can vary slightly depending on how completely the old oil drains, how long the machine is allowed to drain, and whether the filter has been replaced. The 5.3-liter figure should therefore be treated as the service capacity rather than a reason to fill blindly to a specific volume.

What Engine Oil Does the KX033-4 Use?
The KX033-4 operator’s manual specifies engine oil meeting the appropriate API service classification and recommends viscosity according to ambient temperature. The manual lists SAE 10W-30 and SAE 15W-40 among the suitable options across different temperature ranges.
For normal operating conditions, SAE 10W-30 is one of the viscosities specifically identified by Kubota. SAE 15W-40 is also listed for appropriate temperature ranges.
The correct oil viscosity depends on the operating environment. For example:
Always check the latest operator’s manual and the oil manufacturer’s specifications before selecting oil, particularly if the excavator is being operated outside the temperatures normally encountered in your area.
Does the 5.3-Liter Capacity Include the Oil Filter?
Yes. The 5.3-liter KX033-4 engine oil capacity is specified with the engine oil filter. This is important because changing the filter at the same time as the oil affects the amount of oil required.
A new oil filter should normally be installed whenever the engine oil is changed. The filter retains a small amount of oil, so replacing it means the engine needs to be filled to the correct level afterward.
After installing the new filter and adding oil, run the engine for several minutes, shut it down, wait for the oil to settle, and check the dipstick. The KX033-4 manual specifically instructs operators to check the oil level after an oil change because the level can decrease as oil fills the filter and passages.

How to Check the KX033-4 Engine Oil Level
Checking the engine oil level regularly is one of the simplest ways to protect the D1703 diesel engine.
Follow these general steps:
- Park the KX033-4 on firm, level ground.
- Lower the attachments safely to the ground.
- Stop the engine and remove the key.
- Allow the engine to sit for several minutes so the oil can drain back into the crankcase.
- Locate and remove the engine oil dipstick.
- Wipe the dipstick clean.
- Reinsert it completely.
- Remove it again and check the oil level.
- Add oil if the level is below the specified range.
- Do not overfill the engine.
The operator’s manual states that the machine should be stopped and the key removed before checking the engine oil, and recommends waiting after stopping the engine before checking the level.
Kubota KX033-4 Oil Change Interval
The KX033-4 operator’s manual specifies an engine oil change interval of every 500 operating hours or every one year, whichever comes first.
This means an excavator that accumulates only a few hundred hours during a year should still receive an annual oil change. Heavy-use machines may reach the 500-hour interval considerably sooner.
When changing the oil, it is good practice to replace the engine oil filter at the same time. This helps ensure that the new oil is not immediately contaminated by an old filter.

Why Correct Oil Capacity Matters
Using the correct oil level is particularly important in a compact excavator because the engine may operate under significant load for extended periods. Too little oil can reduce lubrication and increase the risk of engine wear. Too much oil can also create problems, including excessive crankcase pressure and oil aeration.
For the KX033-4, the 5.3-liter capacity provides an important starting point, but the dipstick should always be used to establish the final oil level.
Do not assume that adding exactly 5.3 liters is appropriate under every service condition. If some old oil remains in the crankcase, the amount needed to reach the correct dipstick level may be less.
Other Important KX033-4 Fluid Capacities
The engine oil is only one of several fluids that require regular attention. Kubota lists a 44.6-liter hydraulic oil reservoir capacity and 61-liter hydraulic system capacity, while the fuel reservoir holds approximately 46.9 liters.
These capacities should not be confused with the engine oil capacity. The engine requires only 5.3 liters, whereas the hydraulic system holds considerably more fluid.
Final Answer
The Kubota KX033-4 engine oil capacity is 5.3 liters (1.4 US gallons), including the engine oil filter. The excavator uses the Kubota D1703M-DI-E4 1,647 cc diesel engine. Kubota recommends selecting engine oil based on ambient temperature and the required API classification, with SAE 10W-30 and SAE 15W-40 among the listed viscosity options. The engine oil and filter should be serviced at 500 hours or once a year, whichever comes first. After filling, always check the dipstick and avoid overfilling rather than relying solely on the stated capacity.
