Bobcat S570 Oil Capacity: What to Know Before You Fill
The short answer
No verified oil capacity figure for the Bobcat S570 was available in the source material for this guide, so this article does not quote a number. The authoritative capacity for your loader is listed in the Operation and Maintenance Manual that matches its serial number. Use that figure together with the engine dipstick: fill to the specified amount, then confirm the level sits at the full mark before running the machine.
This gap is significant. A capacity quoted without reference to a specific machine can be wrong for your loader, and both overfilling and underfilling a diesel engine can cause problems.
What "oil capacity" can mean on an S570
On a compact loader like the S570, people searching for oil capacity are usually asking about one of several separate fluid systems. Each has its own capacity and fluid specification, and none of them should be interchanged:
Engine crankcase oil: the lubricating oil for the diesel engine, normally quoted as a refill amount that includes a new oil filter. Hydraulic/hydrostatic fluid: the fluid that powers the lift arms, tilt and auxiliary functions, and drives the hydrostatic drive system. Chaincase oil: the lubricant for the drive chains that transfer power to the wheels on each side of the machine.
Before you buy oil, check which system you are servicing. The fluid type and quantity in the manual differ from one system to the next.
Why the figure depends on your specific machine
The S570 was built over several years, and loaders sold under the same model name can differ in engine configuration and emissions equipment depending on production period and market. Any of these differences can change the oil capacity or the recommended oil grade. For that reason, the serial number on the loader's identification plate is the most reliable way to match the machine to the correct manual and service specifications. A Bobcat dealer can also look up capacities by serial number.
How to fill the engine oil correctly
Park the loader on level ground, lower the lift arms and attachment, and stop the engine. Wait for the oil to drain back into the sump before you read the dipstick. For an oil change, add slightly less than the specified refill amount, then check the dipstick. Top up in small increments until the level reaches the full mark. Do not go above it. Run the engine briefly, check for leaks around the filter and drain plug, shut it off, wait, and recheck the level.
Use the oil viscosity and specification listed in the manual for your expected operating temperatures. The correct grade can change with climate, so check that as well as the quantity.
Where to confirm the number
The best sources, in order of reliability, are the Operation and Maintenance Manual for your serial number, the service decal or maintenance chart on the machine if it is still legible, and a Bobcat dealer's parts or service department. If a figure from a forum, parts listing or generic chart conflicts with your manual, follow the manual and treat the dipstick reading as the final check.
