Just to add a little more debate on engine oils, isn't there just one diesel
engine oil available? That, as far as I'm concerned, is Mobil DELVAC One. I
have no connection to Mobil, but am a believer in their product. There's a
good test report that I can't put my hands on right now where the military put
Mobil DELVAC One through some pretty extensive testing and the results were
enough to confirm my trust in the product.

Before someone complains of the price, at $100 a case (4 gallons), I hardly
call that too much to protect my main and GENSET engines.

I'm sure Alex will have the definitive word here. Just as I know that Gil is
trolling for a bite.

However, Mobil DELVAC 1 is a synthetic oil "approved" for all modern
engines. Then they go on to talk of new engines designed for lower
emissions. They don't talk about my 20 year old Perkins!

I earlier had mentioned an oil for sale at COSTCO - Mobil DELVAC 1300 Super
15W40 for $22.00 a gallon. That's more my and my engines "speed."

If you've got a new common rail (?) super injected computer control
EPA-loving diesel - go DELVAC 1. But don't do it on a Yanmar for the first
250 hours or they won't warrant it - unless, maybe it's one of their new
Scania-block engines with computer controls. Then, you still had better
check with Yanmar, Lugger, or whatever.

engine oil available?

Hi Gil,

Actually, there are dozens of oils available for diesel engine
service. What all of those products (including your choice) have in
common is that they have undergone extensive 'formal' testing in order
to meet API and engine builder specifications AND they have also
successfully protected diesel engines in the real world for literally
tens of millions of hours. With respect to real world service, I think
that you'll find that many of the non-synthetic products have records
that dwarf those of synthetics such as the Delvac 1 you mention.

That's not to say that there's anything wrong with Delvac 1. It's just
that, for service in a recreational trawler, the extra expense is not
justified. OTOH: If you want to spend the money, I won't stand in your
way.

Here are links to a few of the 20 or so messages that I've posted over
the years that address this topic:

Hi Alex

Is it possible that my oil problem stems from the engine running too cold?

I am using a 15W-40 weight diesel engine oil.
My IR themometer comfirms that my engine is ruuning on the cool side of the
temp gauge. Possibly because it was set up for workling in a hot southern
California environment. I had assumed that th ethermostat woul dhve taken care
of that but I suppose if the thermostat got stuck in the open position then the
cooerl would tend to chil down the coolant much more up her in the cool PNw
compared to down in hot S. Cal.
