If you need to know which oil to use for a 2008 Cadillac DTS, you're in luck. The recommended oil type for this vehicle is 5W-30 for all temperature ranges. Some suitable options include SYNTEC Synthetic Motor Oil 5W-30 and Mobil 1 Advanced Synthetic Motor Oil 5W-30. The oil capacity is 7.5 US quarts when including the filter. Remember to follow the recommended maintenance schedule in the owner's manual for oil and filter changes. It's a good idea to check the oil level weekly with regular driving and top it up as needed.
The 2008 Cadillac DTS runs best with SAE 5W-30 full synthetic oil.
Can I switch from conventional oil to synthetic oil for my second oil change, or do I need to stick with conventional oil?
