You can't compare a Merlin or TBO's from the 1940's with today's engines. Most Merlin's are modified so that they will be reliable and last some time.

I agree, different oils, fuels and servicing make for revised TBOs, but not by much, the real difference is made by engine management. We take off with 75% throttle on the Mustang, and are surprised to hear that several operators still firewall their throttles for takeoff..

Mike Nixon can give you a quote...

we buy material from the US for our overhaulings: critical components like bearings, pistons, piston rings, valves all contribute to the life expectancy of these engines, but constant monitoring is necessary nonetheless.
