*Note that Kubota's engine oil viscosity recommendations differ from those provided by Bobcat. Both Bobcat and Kubota allow for additional oil viscosities to be used, however their operating temperature ranges are narrow and thus they have been omitted. A wide spectrum of ambient operating temperatures are covered by using either a SAE 15W-40 (especially for hotter climates) or SAE 10W-30 (especially for colder climates). For more information on oil options, refer to your Bobcat owners/service manual or contact your Bobcat dealer.

How to Change the Engine Oil in a Bobcat E20 Excavator

• Orient the machine in an appropriate position so that there is room to place a drain pan beneath the engine and the oil will not drain onto the machine itself.
• Place a suitable container (minimum 4 quart capacity) beneath the engine oil pan to capture drained oil.
• Remove the engine oil drain plug (14 mm socket/wrench for this machine).
• Pull the dipstick out slightly or loosen the oil fill cap to allow the engine oil to drain faster.
• Optional - a section of wiring harness running parallel with the fuel inlet line encroaches on the position of the oil filter. Removing the single nut that secures it to the frame of the machine allows the wire loom to be moved out of the way, reducing the chances that it will become oil soaked when the oil filter is removed.
• Place a series of shop rags/towels below the oil filter assembly to reduce spilling.
• Remove the engine oil filter.
• Carefully clean the oil filter base and ensure that there are no remnants of the old oil filter gasket stuck to the base.
• Lubricate the gasket on the replacement oil filter with clean engine oil.
• Install the new oil filter in reverse order; tighten snug by hand.
• Verify that the engine oil has drained completely, then reinstall the drain plug; snug tight.
• Add 3.5 quarts of engine oil through the oil fill tube, then reinstall the oil fill cap.
• Verify the engine oil level is correct using the dipstick.
• Start engine and verify there are no leaks at the oil pan drain plug and oil filter base.
• We've chosen Amsoil Heavy Duty 15W-40 synthetic engine oil for our machine, which is suitable for operation in temperatures as low as 0 °F and beyond 100 °F. If you're equipment is being operated in extremely cold conditions, a 10W-30 would be a more suitable option.
