Robert,
I respectfully disagree with your assessment on two fronts: first, changing
one's oil every 1000 miles is in itself causing undue stress and wear on the
engine, because at startup, it takes almost a minute for the oil to get up to
normal pressure. That's a whole minute that the oil is not circulating
sufficiently through the internals of the motor; second, a petroleum-based
oil is just simply not going to keep the motor clean, suspend harmful
particles away from critical parts and circulate as quickly at startup than a
synthetic oil.
Not to mention that a cheap oil at K-mart is probably going to be an "auto"
oil which is not going to keep your tranny very happy for very long.
