[C320-list] Perkins m 30

[Warren Updike]

Don't know about synthetic oil restriction. In any event, DO NOT USE standard oil for gas engines. Diesels require a heavy duty oil. I've found that in auto stores the diesel oils are separated from the other oils. They also cost more. 
The current API code is like CJ-4/SM. You'll see this in a circle stamp usually on the rear label. However, as our Perkins M-30's are now over two decades old, the API standard back then was far lower than now. Therefore, any HD Diesel oil you are likely to find on the market today will be fine. 
I buy 10W40 Rotella T oil in six gallon box at Sam's club at about $10/gal. This is about the same price as cheap diesel oil at an auto store.

Eric,
 Thank you for your reply. I had seen a Perkins notice to not use synthetic oil in their engines but I cannot seem to find it again.

Hi Lew,

  The Perkins M30 is a pretty basic engine.  The oil that is called
for is APICC/SE or APICD/SE; but those are old designations.  We use Castrol
synthetic for diesel engines 10/40W.  To fill it completely uses 3.5 litres
(with filter).
  If the motor has a Hurth HBW 50 gear box then the fluid should
be ATF Type A.  He should change it often.

There are generally four filters
that he should deal with.  There is a strainer on the external/cold water
intake.  This should be removed, cleaned and re-installed.  Second one is a
Racor 024 (probably) on the fuel line.  He needs to replace the canister yearly
(at least, or 100 hrs), and inspect the water separator ‘glass’ after each time
he adds fuel.  Drain it if he sees any water down there.
Third is the small
fuel filter that is on the aft part of the engine (yearly/100hrs).  He should
just look at the number that is on it and get one from any auto supply store. 
Whatever brand he prefers will do.  Same thing goes for the oil filter that sits
on the starboard side of the engine.  It is regular height but a bit narrow.
 
If he has to deal with injectors that are gummy, they can be removed and taken
to an engine shop to be cleaned and reconditioned.
NB If he has to deal with
glow plugs that are faulty he MUST get Perkins genuine glow plugs.  NGK will NOT
work!!!!!!!

There are lots of other questions I could answer.

Good
luck,
Eric
