When you're lugging your motor (i.e. flooring it in too high a gear on a
hill), how exactly are you damaging the motor (disregarding
pre-ignition)?
Are the main bearings being damaged because not enough oil is
circulating,
or are the cyclinder walls being scored for the same reason?
Another question: if you're running your motor on the freeway at 4500
rpm,
are you causing a lot more wear than if you had an overdrive and were
only
using 2500 rpm?
Regarding the first part of your question I have no idea but the engine
does not feel right. The second part, if the car is doing 4500 rather
than 2500 then then engine is wearing quicker because the pistons are
moving up and down twice as often.Therefore if you have been on the road
for an hour the engine has spun 270,000 times rather than 150,000. You
are probably using alot more fuel aswell.
