Engine Oil Level Indicator - Reads Incorrect
File In Section: 6 - EngineBulletin No.: 47-61-37
Date: November, 1994
Subject:
Incorrect Oil Reading from Engine Oil Level Indicator
(Measure Engine Oil Level Indicator Length)
Model:
1995 Oldsmobile Aurora with 4.0L Engine
(VIN C - RPO L47)
Condition
Some vehicle owners may comment that more than 7.5 quarts (7.0 liters) of engine oil are required to fill the engine after an engine oil change.
Cause
This condition may be caused by an engine oil level indicator with insufficient length. This insufficient length may result in adding an additional 1/2 to 1 quart (liter) over the recommended 7.5 quarts (7.0 liters) for engine oil to register correctly on the indicator. This condition will not cause engine damage. The 4.OL engine used in the 1995 Aurora required only 7.5 quarts (7.0 liters) (including filter) engine oil to properly fill the crankcase.
Correction
To determine if the vehicle is equipped with a correct length engine oil level indicator, measure the length of the indicator from the flat on the land or upset above the "O" ring to the word "max" on the tip of the indicator. The length should be 618 mm.
Note:
For an interim period, the new fluid level indicator will have a silver dot under the "T" handle of the indicator.
Whenever it is necessary to check the engine oil level in the engine, make sure the vehicle is on a level surface and, to ensure an accurate reading, make sure the engine temperature is 100~C.
Parts Information
Whenever it is necessary to replace the engine oil indicator, refer to the following part number.
