I will assume you mean escalade. We have a 2004 Cadillac Escalade that averages between both city and highway 14.0/MPG. This vehicle is not fuel efficient by any means but very fun to drive
I would say between 10 - 17 miles per gallon
The 2013 Cadillac SRX gets about 17 miles per gallon in the city and 24 miles per gallon on the highway. This is an improvement over last years model which got 12 city MPG's and 18 highway MPG's.
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.
You can get 15 miles per gallon in city, 24 miles per gallon on the highway for 2009 model. On average, the Cadillac XLR will range from 20-30 miles per gallon. However, many things depend on the actual gas mileage. Road conditions, traffic, and speed limit will affect how many miles one gets from a gallon of gas.
17 City/26 Highway
30 gallon capacity tank in a 1999 cadillac escalade only 11 miles to the gallon city and 14 highway
17 city / 26-29 highway
That depends on how heavy your driving foot is and the sort of driving you are doing.
City-10-12 Highway-15-18
My 1997 gets about 27 mpg highway, much heavier in city driving.
20 miles to the gallon 20 miles to the gallon
15 miles to the gallon 15 miles to the gallon
