Subject: RED COLORED ENGINE OIL -
1983 - 1984 VEHICLES
Some late production 1983 and some 1984 vehicles will have red colored engine oil. The red color is due to the red dye which is added to the engine oil to aid in detecting leaks during manufacturing.
The red dye does not affect any lubrication characteristics of the engine oil and, therefore, the oil should not be changed.
Owners should also be made aware of this practice.
