Oil Change Frequently Asked Questions
Q: Should engine oil be replaced every 3,000 miles?
A: Most Cadillac vehicles are equipped with the OLS, which has made the 3,000-mile oil change obsolete. Depending on the age of your Cadillac, driving habits, and road conditions, your advanced engine may be able to go longer than 3,000 miles between oil changes. Always be sure to check your engine oil level regularly, even with an OLS.
Q: Does regularly changing my oil filter help with the life of my engine?
A: Yes. An oil filter helps ensure your engine is lubricated with clean oil, which is important to optimal engine performance. Both your vehicle’s oil and oil filter should be changed at least as often as recommended by your OLS and/or Owner’s Manual.
