Mid- to high-30's for me. If I'm really pushing (engine always between 4K and 7.5K), I can get the low-fuel at 110-miles, but typically is more like 125-130. (All US units.) My issue right now is light pinging now and then, even on 91+ premium. I think what everyone says about the engine mgmt. system leaning the system out under steady state is correct - mine pings mostly when I've been dogging it and then give it a good whack of throttle.
