TRUCK ENGINE NEWS, SEPTEMBER 1, 1982, PAGE 4. Some of the information in the article "Excessive Oil Consumption: Check The Accuracy Of The Oil Level Gauge " is not complete. Make a reference in that issue to a new article in this issue with the same title. The new article has all the information from the earlier article plus some new information.
--------------- END SUPPLEMENT ---------------
There are several different causes of excessive (more than normal) oil consumption. One possible cause is overfilling (oil level that is too high). If excessive oil consumption is caused by overfilling, the oil consumption rate will return to normal when the volume of oil in the system has decreased to the correct level.
To prevent overfilling, it is important that the "full " mark on the oil level gauge give an indication of the correct volume of oil needed for the engine.
The procedure which follows and the capacities in the chart can be used to make sure the "full" mark on the oil level gauge is in the correct position.
1. Drain the oil and remove the oil filters. Permit the engine to drain for at least 15 minutes.
2. Install new filters.
3. Add the volume of oil shown in Column A of the chart. Remember to add additional oil, as necessary, to engines equipped with auxiliary filters.
4. Start the engine and operate it long enough to fill the internal passages and filters with oil.
5. Stop the engine and let the oil drain back into the oil pan for at least 15 minutes. Check the level of the oil on the gauge. If the gauge mark is correct, the oil will be at the "add" mark. If it is not at the "add" mark, make a new mark at the location of the oil level in the engine.
6. Add the volume of oil shown in Column B of the chart. Check the level of the oil shown on the oil level gauge. The correct position is at the "full" mark. If it is not at the "full" mark, make a new mark that is the same as the oil level in the engine.
