Bought my jeep new 3 months ago.
Dealer sticker on windshield says service due at 5000 kms
Dealership brochure says 6000 kms
Jeep "maintenance book" with dealership sticker says service due at 10000 kms
Manual/warranty/website says 13000 kms
The decal actually says 5000kms, and todays date. I expect a call, at which time I will question why so many contradictory dates.
Of course I changed it myself already last weekend, probably the easiest oil change I have ever done. I haven't decided the intervals I will follow though...
