The 3% variance is probably the variance in how much you filled the tank at each fill up. The only way to accurately compare manually from one fill up to another is to fill the tank up to exactly the same level each time. Pretty hard to do on the Z since you can't really see the fuel level down in the tank.

I'd trust the computer.
