Thanks guys for the great info. Actually, Doug, I was just trying to
find out if an unused diesel that had not been used for three years
COULD still be any good at all.

Oh sure.


Actually the engines are less than 10 years old. I guess I should hope
the oil hasn't been changed the day before I arrive...

If you take a cold oil sample and a hot oil sample, as Jim W suggests, then the results will reveal the oil change.
It's difficult (or impossible) to fool a good analysis tech.
