Welcome to the forum. For me it really took a while until my engine was "loose" and felt broke in. 2K-3K for me until it coasted a little when you turned it off.
The fuel thing is a science in itself. I myself have a thread from a year ago on this topic. Bottom line for me: I have a 4.8 gallon tank. The 30 mile reserve light comes on when I have 1.7 gallons left in the tank.
It seems like everyone's is a little different. When I replace my fuel filter I am going to form the float arm so it is more accurate.
