Does driving slower save fuel?

Going slower technically saves fuel because at high speed your engine needs to work harder to overcome drag from wind resistance, your tyres and transmission, and that drag increases exponentially the faster you go. Reduce your speed, then less power (and thus fuel) needs to be expended to overcome that drag.

Do cars run better with full tank?

When a fresh, full, cool, tank of fuel is available, the engine computer will be able to advance the timing again, and start the short term fuel trim over from a slightly richer setting, both things contributing to better performance.
