A point of interest is that the oil on the larger diesels is usually changed

That makes a lot of sense for engines that are running nearly
continuously. It only takes 4 days to get to 100 hours in that kind
of service. There are times when I will do 100 hours in a week, and
others when I won't do that in 6 months.

Wayne,

Oil analysis could be useful in your situation if based upon intervals based
upon days.

Many dealers offer the service locally. Cat & Cummins come to mind but I'm
sure DDA and others do it as well. If interested contact a dealer and see
if they will recommend a program for your engines. Probably won't save you
much $$ but may provide some peace of mind and save you some unecessary
work.

Merry Christmas!
