Engine Break-In/urban legend
I always found it curious that car engines are recommended to be broken in gently, no hard acceleration, etc, while new or rebuilt aircraft piston engines are required/recommended to be broken in at full throttle for the first 50 hours.
One of these recommendations are clearly wrong. Someone explain this to me. I wonder which one is the Urban Legend.

maybe they're both right. differences in metals, air-cooled vs liquid-cooled, differences in cylinder taper(if any),piston/ring design, could all result in a very different break-in procedure. also to be considered...an aircraft has an adjustable mixture where during break-in it could be run fairly rich and keep cylinder temps within tolerances. cars don't have this feature.
this is just a guess. anyone know for sure?

Tollerances, mass produced engines need to bed it, for my race engine I never say 'hold on lads, i'm running this baby in, could we perhaps race half throttle for the first 20 laps' 
Also most engines need time to be opperated at correct temp's, if you have to run a cam shaft in at 3000 rpm for 20 minutes you hoping your mixture is somewhere right, and the cooling is up to the job (not always predictable in hot rods), I know every blueprinted engine is running at very specific tollerances and machining variance is eliminated, saying that most new engines that are much better machined do not require running in. Back in the 60's fxrd used to make a pre x-flow engine, when the set the tooling the engines had a dial allocating them to certain engine grade, the 8,9 were for the GT, the 10's were for the lotus twin cam, the 5,6 and 7's were for the GL and anything after then were just junker engines that were put in the base models. I think with advances in machining practice in mass produced engines the ned to 'run in' has been reduced. Just my take on the world.

Link to an Oil Filter study
http://minimopar.knizefamily.net/oilfilterstudy.html
For really good info go to http://bobistheoilguy.com/
Generally Purolator filters are the best things for Fords. (Even motorcraft ones are made by Purolator). I prefer to use Valovine Maxlife Oil filters, since they are cheaper than the motorcraft ones, and are also made by purolator.

I think one must give credit to the manufacturer parts on this one. They are the ones guaranteeing their motor to go 50 k. They really should be given the benefit of the doubt.
Like when toyota says 10k between oil changes or Honda 7000. They are the ones holding the bag, as it were.

Aircraft engines can be compared to 2 cycle lawn equipment engines on trimmers, edgers, etc. They are designed to operate at full throttle, they perform best that way, generally last longer that way, and some even get the best fuel efficiency that way.
I know neither of the above literally always operate at full throttle so don't go there. Instead look at the normal use of those engines as compared to one in a vehicle.
Vehicle engines must put up with up and down RPM's as an almost constant. Changing speeds, idling for various reasons, being started and stopped sometimes many times a day, etc.

That seems to make sense. When I fly a naturally aspirated aircraft, mostly cessna 182 with 470 ci engines , I leave throttle wide open the whole flight until I need to land. Maybe you break in the way you will use.

and here I was telling YOU about mixture....
I'm jealous ken. been wanting to get my license for years now. lack of money or time has thus far thwarted my attempts. have had to settle for R/C flying in the meantime. and of course the sim on the comp.

Man, I tried that R/C stuff, that 's hard. You can really do that? Flying airplanes is easy. Landing is hard,
seriously, if you have a use for it, its not all that expensive. If you just fly around in circles, than it is very expensive. Can't you say the same thing about the aerostar.
