Hi everyone, I recently purchased a used Cadillac DTS and I’ve been curious about some aspects of its powertrain. Specifically, I want to know more about the Cadillac DTS engine, its reliability, common issues, and maintenance tips. How does it perform over time, especially in higher mileage vehicles? Are there any known quirks or modifications that improve efficiency or longevity? I’d also like advice on servicing intervals and recommended fluids. If anyone has personal experience or technical insight on the Cadillac DTS engine, your guidance would be greatly appreciated.
