Oil Maintenance and Service Tips
Check engine oil level regularly using the dipstick before starting the engine when the vehicle is on level ground. The oil should be between the minimum and maximum marks on the dipstick. Change the engine oil and filter according to the Oil Life Monitoring System display or at minimum every 7,500 miles under normal driving conditions.
Severe driving conditions require more frequent oil changes, including towing, extensive idling, driving in dusty conditions, or frequent short trips in freezing temperatures. Always use dexos1 certified full synthetic 5W-30 oil to maintain warranty coverage and optimal engine protection. When changing oil, replace the oil filter with an ACDelco PF63 or equivalent that meets GM specifications.
The oil drain plug must be torqued to 18 lb-ft to ensure proper sealing without damaging the oil pan threads. Reset the Oil Life Monitoring System after each oil change by following the procedure in the owner’s manual. Dispose of used oil and filters at an approved recycling facility.
| Driving Condition | Oil Change Interval |
|---|---|
| Normal Driving | Every 7,500 miles or 12 months |
| Severe Driving | Every 5,000 miles or 6 months |
Frequently Asked Questions
What kind of oil does a Cadillac XTS use?
The Cadillac XTS requires dexos1 certified full synthetic motor oil meeting GM specifications. ACDelco Dexos1 Full Synthetic or Mobil 1 Advanced Full Synthetic are recommended brands that meet these requirements. Using non-dexos1 oil may void warranty coverage and cause engine damage.
How much oil does a Cadillac XTS take?
A Cadillac XTS takes 6.0 quarts (5.7 liters) of oil with a new filter and 5.5 quarts (5.2 liters) without the filter. This capacity applies to both the standard 3.6L V6 and the twin-turbo V6 V-Sport engine. Always verify the oil level with the dipstick after filling.
What is the recommended oil viscosity for a Cadillac XTS?
The recommended oil viscosity for all Cadillac XTS models is SAE 5W-30. This viscosity grade provides proper engine protection across a wide temperature range. Do not use other viscosity grades unless specifically approved in the owner’s manual for extreme temperature conditions.
What is the oil change interval for a Cadillac XTS?
The oil change interval for a Cadillac XTS is every 7,500 miles or 12 months under normal driving conditions. The Oil Life Monitoring System will alert you when service is needed based on driving habits. Severe driving conditions may require oil changes every 5,000 miles or 6 months.
What oil filter fits a Cadillac XTS?
The Cadillac XTS uses an ACDelco PF63 oil filter or equivalent alternatives including Mobil 1 M1-110A and K&N HP-1017. The ACDelco PF63 is the OEM part number for all XTS model years from 2013 to 2019. Always ensure the replacement filter meets GM specifications.
Can I use synthetic blend oil in my Cadillac XTS?
While dexos1 synthetic blend oil meets minimum requirements, full synthetic oil is strongly recommended for optimal engine protection and performance. Full synthetic oil provides superior high-temperature stability, oxidation resistance, and cold-weather flow characteristics compared to synthetic blends. Many owners report better engine response and fuel economy with full synthetic formulations.
Conclusion
The Cadillac XTS from 2013 to 2019 requires 6.0 quarts of dexos1 certified full synthetic 5W-30 motor oil with filter for all engine variants. Using manufacturer-approved oil specifications ensures proper engine lubrication, maintains warranty coverage, and prevents premature wear. Regular oil changes at 7,500-mile intervals using the correct ACDelco PF63 filter help maximize engine reliability and performance throughout the vehicle’s lifespan.
