Warranty an 5k oil service

[craigdub]

Has anyone had to claim on their warranty and not had the 5k oil services done, the dealer, Jeep, have told me if I don't have the oil services done by them then my warranty claims would be rejected!
Anyone know if this is correct?

5k on the SRT unfortunately. It's 630aed, so I suppose not too bad for nearly 10 litres of oil.
