The best and only gas to use to keep your caddy emmission clean is 93' octane. preferably from a Shell's gas station.
The best gas for a 1999 Cadillac STS is premium unleaded fuel with an octane rating of 91 or higher. Using higher octane fuel helps optimize engine performance and efficiency, as the STS is designed to run on premium gas. While regular unleaded may be used in a pinch, it is not recommended for long-term use due to potential knocking and reduced performance. Always consult the owner's manual for specific fuel recommendations.
The Cadillac STS is currently rated with the best gas mileage. The new Cadillac Escalade Hybrid is also top on the list for good gas mileage.

In the 2008 Cadillac STS, the gas tank release button is located on the driver's side, near the floor, just to the left of the seat. It is typically a small lever that you pull up to open the fuel door. If you are having trouble finding it, check around the area near the driver's side door.
