I kinda doubt this with more modern engines. Older engines, that didn't run at stoichiometric all the time will obviously use more fuel at higher engine loads. This is much less common in engines today. They run 14.7:1 nearly all of the time unless they are seeing some higher rpms and high load. Smaller engines leads to increased load, and increased load means greater efficiency IF air/fuel ratios are kept the same. Its not absolutely universal, but pretty darn close.
