I have an 11 Silverado with 5.3 and installed a Range AFM disable on it, and average about 19 MPG empty, but I do like the truck a LOT better with the afm shut off (wish I had bought the 6.2 that year that did not have the afm). Not much difference in mpg with the afm disabled, and seems a little better actually as I usually averaged about 18 before I plugged in the Range device. Guess this does not have any bearing on the OP questions on the Fords though, but I have always wondered about the longevity of the turbo 6's, I guess time will tell. Myself, I wish someone would build an inline 6, as I always liked inline 6's better than V6 engines. Guess that is out of the question. It is ironic I bought a new truck in 92 with TBI engine, 3:73 rear end, and 5 speed manual, and it got nearly identical MPG as the 5.3 in my '11 with 6 speed auto, and 3:42 rear axle (both were 4x4s)... 20 years later, yet we read about all the increased efficiency in engines.....yeah my 11 is more comfortable, and generally more powerful, but still goes same miles on a gallon of fuel -- go figure. Seems we are fighting a losing battle in some ways, as for every aluminum body panel, or additional overdrive or higher gear ratio they install, they hang another air bag, on that offsets the savings in weight. End of rant.

Today's Featured Article - What Price Enthusiasm? - by Anthony West. Quite frankly, for some time now restorers like myself have become more and more concerned about the rapid increase in the prices of old farm machines here in England. There is now a growing market for "As found" machines. Which as machines get rarer, has found the birth of a new industry....one of the "procurement agent". These agents appropriate as much old machinery as possible then inflate prices at auctions. So at what price enthiusiasm? We are now seeing poor machines which 3 years ago ma
