RE: [DML] delorean engines...miles or hours?

["Scott Gardner" <gardners14@xxxx>]

	One thing to keep in mind is that the engines in different
vehicles are used in different ways. In my plane, engine age is
determined in hours, as well, but part of the reason is that the engine
and the props are always turning at a constant speed, with the amount of
thrust being varied by changing the blade angle of the props as they
spin through the air. In this case, engine hours are a pretty good
indication of wear, since one hour is much like the next.
In a car, to use engine hours as a measure of wear, you run up
against the problem of not knowing whether a particular hour was spent
idling, at part throttle, or at full throttle.

Subject: [DML] delorean engines...miles or hours?

Just a curious question about automobile engines. I know the standard
way to 
tell how "used" an engine is is by the mileage. On our cars since many
have 
sat, had broken angle drives or had sporadic periods of use I was
wondering 
other ways to tell how much use an engine has had. Just like the way the
car was 
treated the past 20 years shoud be more important then 81,82 or 83 I
would 
think there are other ways to help judge an engines life.

Since my brother is an avid boater they refer to an engines age by the 
"hours" it has logged. Which made me wonder which is truly more
accurate, hours or 
miles??? Are there ways on an engine that measure things that may be
more 
important then miles? Can you tell how many hours your engine has
logged?..... 
Since I have a relativley high mileage car this tells me he simply drove
it alot 
and it was well maintained to do so....
