Proper oil maintenance is crucial for the performance and longevity of your 2020–2023 Cadillac CT4. This model offers two engine options: the L3B 2.7L I-4, which requires 6 quarts of 5W-30 oil, and the LSY 2.0L Turbo 2.0L I-4, needing 5.3 quarts of 0W-20 oil. Regular oil changes not only ensure optimal engine performance but also help maintain the vehicle's overall efficiency.
In addition to oil, it's essential to monitor coolant levels for both engines. The L3B engine has a coolant capacity of 13.7 quarts, while the LSY engine holds 11 quarts. Keeping these fluids at the recommended levels will help prevent overheating and ensure that your Cadillac CT4 runs smoothly for years to come.
