Hi, I just bought a 1980 deville and I wondered what is too, all it does is indicate that you are using more gas then is required for optimum gas mileage. If all fails look in your owners manual as I did as a last resort.

Yes, it is the economy light. As creeker said, it's simply telling you that the way you a driving right now gives you bad gas mileage. On the '76, and probably the '79, there's one that lights up green if you are doing good.

one thing that i really likle about the caddy is that it has as you know a 425 big block..and ever since i have had this car it has never overheated and im suprised with such a big engine..even when i had my water pump go out and i had anti-freeze shooting all over my engine it still never overheated..i love caddy's

The 425's are one of the most reliable engines Cadillac ever made! One of the 1979's went 600k miles without a rebuid!
