Typical oil level gauge for C-12 and C12 Marine Propulsion Engines (Y) "ADD" mark. (X) "FULL" mark. (Z) "Effective Length". (Z-LH Service Engines) 642 mm (25.3 inch) (Z-RH Service Engines) 479 mm (18.9 inch) | |
The angle of installation will affect the "ADD" mark (Y) and the "FULL" mark (X) that is engraved on the engine oil level gauge.
The engine oil level gauge must be calibrated after the engine is installed in the vessel. Use a marking pen in order to engrave "ADD" mark (Y) and "FULL" mark (X) on the engine oil level gauge.
Calibration Procedure

Refer to the Operation and Maintenance Manual for more information on lubricant specifications. |
Note: Check the oil. Many engines are shipped without oil.
- Operate the engine until normal operating temperature is achieved. Stop the engine. Remove one of the drain plugs for the engine crankcase. Allow the engine oil to drain.
- Remove the used engine oil filter. Install the drain plug for the engine crankcase. Tighten the drain plug for the engine crankcase to 70 ± 14 N·m (50 ± 10 lb ft).
Note: The engine may be equipped with auxiliary engine oil filters. The extra filters require more engine oil than the standard amounts. Refer to the OEM specifications.
- Clean the sealing surface of the filter mounting base. Ensure that all of the old oil filter gasket is removed.
- Apply clean engine oil to the new oil filter gasket.
- Install the oil filter. Tighten the oil filter until the oil filter gasket contacts the base. Tighten the oil filter by hand according to the instructions that are shown on the oil filter. Do not overtighten the oil filter.
- Add the recommended oil grade and weight of engine oil to the crankcase:
Standard Sump ... 24.6 L (26 qt)
- Start the engine. Ensure that the lubrication system and the new engine oil filter is filled. Inspect the lubrication system for leaks.
- Stop the engine. Allow the engine oil to drain into the engine crankcase for approximately five minutes.
- Check the engine oil level. Use a marking pen in order to engrave "ADD" mark (Y) .
- Add 3.8 L (4 qt) of the recommended oil grade and weight of engine oil to the crankcase. Full volume will now be 28.4 L (30.0 qt). Allow the engine oil drain into the engine crankcase for approximately five minutes.
- Check the engine oil level. Use a marking pen in order to engrave "FULL" mark (X) .
