Fuel Economy lacking
By chuck on
2008 Cadillac DTS Luxury II 4dr Sedan (4.6L 8cyl 4A)
I have had several Cadillacs including a 2006 DTS that got good to excellent gas mileage.I use the DTS primarily as a short to long trip car,so it's mostly highway driving.Still the mileage as recorded by the computer fuel monitor is in the low 20's, where the 2006 was in the mid 20's. As far as the looks and comfort of the car,I am well pleased.
