Look down into the engine, if the parts are still metal looking it's good. If maintenance has been lacking then the metal parts will have a reddish brown buildup. Consider having an engine flush done if you find the latter.
Hi Dux,
With the extended oil changes on the new cars, sludge builds up anyway, even if the oil is changed every 10k, or when ever the maintenance warning comes on. Sludge build up isn't a good indicator of regular oil changes in these extended service cars any more.
