Planebuilder does allow for you to change the efficiency of the engines on the "Powerplant" page. Altering the efficiency box will change the speicific fuel consumption (in lbs/ hp-hr). Planebuilder gives the "normal efficieny as being between 20 and 25% for piston engines which is a bit off. Example would be the Allison V-1710 with a fuel consumption of 0.66lb/hp-hr (15% eff) the RR Merlin (about 17%). THe really, really good ones can get up to 22% eff or so. For diesels, maybe 24-25% eff.
