Actually, cold temps increase performance, but warm weather increases MPG.

Weather doesn't really effect "fuel", but it does effect the density of the A/F charge. Cold air is more dense, so lower ambient temps actually increases the amount of A/F into the engine. And you not only get a bigger A/F charge, yoou get an increase in the effective CR...its like free FI.
