Hey everybody,

I have an 04 TJ , 4cyl with auto transmission i bought in June and always
have 12k miles on it ( 80+ miles a day plus frequent road trips)...and
obviously I will be putting a lot of miles on this jeep in a short period of
time....

So I got to thinking, do transmissions and engines fair better or worse if
you put more miles on them sooner, or over time.

For example, if I was to reach 100k miles in 2 years, would it do more
damage than if I did it over 5 years.

Heres my reason for asking....my non-mechanically inclined brain would think
that since the components are "younger" , they could handle more miles. But
an older system would start to break down since its "older" around that
mileage range...is this the case?

Does somebody care to explain the effects of high mileage in short periods
of time on jeeps...

thanks
ed

 

I'm sure others have more specific answers, but I've always experienced that
vehicles with a lot of highway miles (and likely newer) are in much better
shape than their counterparts with the same miles that may be older (if they
were mainly stop-n-go miles).

Typically lots of miles in a shorter period causes less wear than the same
mileage over a longer period. The most significant reason is fewer starts
and stops for the same miles travelled. The bulk of engine (and trans to a
certain extents) wear can be attributed to the few moments at start-up
before lubrication finds it's way to everything. So, the fewer times you
start the engine to drive a given mileage the less wear. Has little if
anything to do with the "youngness" of parts.

Trannies also get roasted by folks that tow too much for too long without
allowing proper rest stops or having an aux cooling coil.
