Question type: Maintenance & Repair

I just(3 wks ago) bought a 2002 cadillac
escalade and it has run perfect. But last
week i started getting a message saying to
change engine oil. Today The service
engine soon ligjt came on. I checked all
fluids and everything is fine. Is it just telling
me it needs an oil change or could there be
something wrong?

Change the oil message is basically a timer that is reset after every oil change, consult your owners manual on how to reset this or change mileage intervals. However the check engine light is something all together different, it is telling you something is wrong with the engine control systems, most parts stores can pull the codes for you, write them down and then re-post them back here and someone will help you through further diagnosis.
