Sure it does. I've had a 182 and now a Bonanza. The 182 wouldn't run
LOP as that term is understood. The problem is that in order to run LOP
all cylinders must get to peak at the same time, or very nearly so. If
you can't accomplish that then LOP flying won't work in your engine,
fuel injected or carb'd. As for fuel savings the book flow for my 520
is 9.3 gph at 45%, I can run all day at about 7.5-7.8 That's a big
savings from the guy who can't go LOP in his aircraft.
