Habtoor insists that we should Change Oil and Filter every 5000 Kms, Nowadays they use synthetic Oil, Uptil 100,000 Kms I changed every 5000 Kms, Keeping the Car for every Oil Change was Pain , and The labor of Habtoor has become very expensive, For couple of last service I changed for 15000 Kms from XADO and I see no problems , and each Time XADO garage flushes the engine, and the Car is smooth, Any advices on oil Change after kilometers.
