The type of work an engine does has a big impact on miles per gallon. Nothing better illustrates this than my 2.2 litre Ford Ranger 6 speed automatic. This is a fairly thirsty engine by today's standards.
On long solo unladen journeys, which it seldom does, it is easily capable of 30mpg. However, my combination of short hard journeys and towing means that it averages between 17gallon tankfuls, how much do you think? 25? 20? No, it varies between 17 and 19mpg.
In isolation that sounds terrible, but it does have 150hp and 350Nm torque and an automatic. It also slightly betters the consumption I got for 22 years from a manual Land Rover 110 pickup with a 2.5 non-turbo engine developing all of 67hp doing the same work but m..u..c..h s..l..o..w..e..r. which would only do 25 at best solo unladen long distance.
