Do I need to use unleaded gas in a Cadillac Deville?

Answer by  Jimbob (2275)

You probably due want to put unleaded gas in your Cadillac. Most modern cars require unleaded gas and even cars that would burn leaded gas will still accept unleaded, but not the other way around. The leaded gas will quickly ruin the sensors and delicate workings of an engine that requires unleaded.

If the car is newer than 1975 and has a catalytic converter, almost certainly. There should be a label on the car telling you what kind of gas to use.

Any gas you buy today from a pump will be unleaded. If you have an older vehicle that was intended to be run on leaded gas you need to modify your internals so you can run modern gas. If it is a newer Cadillac then you shouldn't have any problems as long as you use the right octane.

Yes. All modern gas sold at gas stations is unleaded. Modern cars since the early-mid 1900s have all used unleaded gasoline. So yes, you need to use unleaded gasoline in your DeVille. As long as it is the correct octane, all gas from any major gas station should be fine; unless it is marked as leaded gasoline.
