How do you get your 1990 Cadillac Sedan Deville fuel temp and mileage reading off of metric and back to USA standard reading?

EDIT Push the "E/M" button that sticks out of the speedometer display, and looks like the trip reset button.

There isn't a E/M button on this particular model, at least not on my 1990 Cadillac DeVille.

underneath the dash on the drivers side by the ash tray there is a one wire connector. disconnect for English, connect for metric.

This answer worked perfectly. as you are looking at the Ash tray to the left side between ash tray and steering column, the wire is behind the covers on the bottom of the dash. You'll have to take off the two screws holding the cover that covers the steering column. Then, you will see (at least on mine) a connector with 1 wire. A Black wire and ont he other end a baby blue wire. Unhook it and English system. Hook it up, Metric. Thanks!

In all likelihood, the answer to your question is "Yes". When you remove the dipstick, you can validate this by reading the message that is imprinted thereon. (Also this information is in the operator's manual in the service section.)

It is the mileage that is actually on the car. If the odometer is replaced, the correct reading is written down. Add that to the reading of the replacment odometer and you have the actual mileage on the car.

on carfax, last mileage reading was Aug. of 2009. Why no reading more recently?
