i have a 3.5L, did the first oil change at 5000km. the "change oil" light is supposed to come on to indicate oil changes. when i went in, the dealer said that the dealership recommends changes every 5000km but chrysler canada says 10,000km or when the light comes on. I got my oil changed at brampton chrysler for a total of $48. seems a bit too expensive, i might be looking for some other shop like active green & ross.
