I have a 90 Coupe DeVille and I the digital readout said 1 gallon and i put a little more than 15 gallons in, but i dont know how accurate it is. Answer The 90 Cadillac DeVille holds 18 gallons of premium fuel. I have found the digital fuel monitor system to be very accurate within a tenth of a gallon most of the time but it will read F (full) anywhere above 15 gallons.

A 1990 Cadillac Deville air conditioner should hold 46 oz. R12 Freon. This should be verified through the owners vehicle manual.
The number of miles per gallon that the 1997 Cadillac DeVille can achieve is dependant on a number of factors such as the condition the vehicle is in or the driving style of the driver. However, the Cadillac DeVille is believed to get between 17 and 23 miles per gallon.
it depends on how much gas you got if its empty empty it should take up at least 18-19 gal.
14 in the town and 24 on highway... usually 17 mile / gallon
