Bobcat MT100 Engine Oil Capacity: Where to Find the Correct Figure
The short answer
The Bobcat MT100 is a compact mini track loader with a diesel engine. Its engine oil capacity is a documented specification that Bobcat publishes in the machine's Operation & Maintenance Manual and service literature. No verified capacity figure was available for this article, so it does not state a number. Treat any figure you find elsewhere with caution unless it comes from Bobcat documentation that matches your machine's serial number.
Two qualifications change the answer. First, the listed capacity usually assumes the oil filter is replaced at the same time. A drain without a filter change takes slightly less oil. Second, specifications can differ between production years, engine versions or market-specific builds. Use the figure that applies to your serial number range.
Where the documented figure is published
Operation & Maintenance Manual: check the specifications section for fluid capacities and the maintenance section for the engine oil and filter procedure. Service schedule decal: many Bobcat machines carry a maintenance decal listing service intervals, and some also list fluid types. Confirm what the decal on your unit shows. Bobcat dealer parts and service department: a dealer can look up the capacity, recommended oil grade and correct filter part number from your serial number. Engine manufacturer documentation: the engine's own manual may list oil capacity. However, the equipment maker's oil pan and filter setup can make the installed capacity differ from a generic engine figure, so the Bobcat figure takes priority.
How to confirm you have the right machine and configuration
Bobcat sells several mini track loaders with similar names and layouts, including the MT55, MT85 and MT100. Their engines and fluid capacities are not interchangeable. Confirm the model before using any figure.
Model decal: look for the MT100 designation on the machine's bodywork. Serial number plate: record the full serial number from the machine identification plate. The Operation & Maintenance Manual shows the plate's exact location for your configuration. Specifications are often tied to serial number ranges. Engine identification: the engine carries its own identification label showing its make and model. This helps if you cross-check against engine documentation or order filters. Manual match: make sure the manual you are reading covers your serial number range, not just the model name.
Locating the dipstick, fill point and drain
The dipstick, oil fill cap, oil filter and drain point are reached through the machine's engine access covers. Their exact positions and the access procedure were not confirmed for this article. Follow the illustrations in the Operation & Maintenance Manual for your serial number. Open the engine compartment only with the engine stopped, the machine on level ground, and any lift arms lowered or properly supported as the manual directs.
Filling correctly, whatever the listed capacity
The published capacity is a starting point, not a substitute for the dipstick. Old oil left in the engine, the filter's fill state and the machine's angle all affect how much the engine accepts. A cautious approach is to add somewhat less than the listed amount. Then run the engine briefly if the manual allows, shut it down, wait for the oil to settle, and top up in small amounts until the level reaches the full mark on the dipstick. Overfilling can be as harmful as running low.
Use the oil grade and specification Bobcat recommends for your operating temperature range. The recommended viscosity and service classification were not confirmed here. They are listed in the manual's fluid and lubricant section, alongside the oil change interval.
Information gaps in this guide
The numeric engine oil capacity for the MT100, with or without a filter change, was not verified and is not stated. The engine make, model and any differences between production years were not confirmed. The exact locations of the serial number plate, dipstick, fill cap, filter and drain were not confirmed. The recommended oil grade and change interval were not confirmed. For all of these, use the Operation & Maintenance Manual that matches your serial number, or ask a Bobcat dealer.
