Check engine oil levels regularly. Unscrew and pull out the dipstick (look for a yellow loop handle), and examine it. Before checking the oil, shut off the engine and allow the vehicle to set for a few minutes to allow oil to drain into the oil pan.
The Cadillac Oil Life Monitor (OLM) system is not a simple oil quality sensor, but a software-based, algorithm-driven device that considers various engine operating conditions to determine when the oil needs changing.
Certain driving habits can affect the life of the oil, as well as driving conditions such as temperature and driving terrain. Lighter, more moderate driving conditions and temperature will require less frequent oil changes and maintenance, while more severe driving conditions will require more frequent oil changes and maintenance.
