How to prevent food sticking on Weber Q1000 grill?

Heavy on the oil directly to the food. Let the meat sear, if you try to move or flip it too soon, it sticks. Let it sit and it will release without tearing off and leaving meat on the grill. After grilling, crank up the heat and after a bit, use a wire brush to clean it for the next use. Sometimes stuff left on the grill will be the cause.
