my opinion to keep fuel tank full is also to avoid the air going to much into your full tank. The reason is because unleaded fuel can easly be vapourised into the air. I used to clean my cylinder block with unleaded and air compressor so i know
in my 40 years in the motor trade petrol has always been used as a cleaner, there is nothing better for cleaning engine components. Fuel will not vaporize if it is correctly sealed.

As for putting rocks in a fuel tank.....that's a new one on me. what advantage would you expect to gain?
