INSPECTION AND ADJUSTMENT 3.1 CHECKING ENGINE OIL CONSUMPTION Engine oil consumption relates to the engine oil used during combustion in the engine. Since engine oil consumption is affected by driving style and the use to which the vehicle is put, it is also related to average fuel consumption. See "Technical data" for the maximum permissible engine oil consumption. Test conditions An engine oil consumption test is only meaningful after the engine has been run in (approx. 25,000 km). 2. Check the engine carefully for engine oil leakage before carrying out an engine oil consumption test. First repair any leaks. 3. Check the average fuel consumption and engine oil consumption as accurately as possible. 4. Only check the engine oil level when the engine is at operating temperature and only when the engine has been turned off for five minutes. 5. Make sure the vehicle is horizontal before checking the engine oil level. |
