[C320-list] Perkins M30 Oil Change

[P.F. Ross]

David, timely question since I just changed my oil today.

As others have said, I run the engine for 10 mins or so to heat up the oil
a bit.  I use a West Marine manual pump system that has a stiff plastic
tube that I push down the dipstick tube.  Although it is hard to tell
exactly what the tube is doing as it comes to a stop, I figure that if I
get close to 4 qts of oil out, I must be doing it right.  To double check,
I move the tube up and down a bit toward the end of the process and if all
I hear is a sucking sound (requires some extra pumping), I figure I am
finished.

I have considered using the oil extraction tube but have never thought far
enough ahead to get the correct barbed fitting.  So I just use the dipstick
tube method, works fine.
