Stretching Generator Oil Change Interval

Yes, We are using all synthetic on NL 12, 20, BMZ 20 (Isuzu 4LE1) and a kluge D1105, 9.
Oil labs are coming back perfect past 300+ hours.

I believe it was the synthetic oil that saved that D1105 when an intake valve stuck open and fuel washed the lung. The 9 is now all together yesterday and running great & strong.
Yep, I under loaded a 9kw. Frack Me (FM).

I queried NL years ago about synthetic. Official statement was dino oil was only approved under warranty.
After that, no comment or concerns.

We are a big believers in synthetic oils. Just wish it was available in CF-2, 40.

I usually run 200-250 hours on the Cummins powered Ohnos or my Isuzu powered Norpro. But indeed once you have everything handy and setup, 30 minutes is all it takes incl racor and sec. No big deal

Shopping for oil and filters is depressing enough.
Dragging a pail of oil on/off the boat.
Disposing of old filters and oil.
Cleaning up.
15 to 30 minutes uh?

During our vacation, we ran our gen-sets over 1000 hours.
The Isuzu received 3 oil changes while deployed, while anchored, in a hot engine room.
On board; fresh pails of oil.
On board; big box of new filters and oil-sorb pads.
On board; empty pails for the used oil and used filter storage.

That is a lot of logistics time and labor.
I know some resources may be easier for Dockmaster in AK, but during and after his time moving south, his logistics will become more painful.

Removing one or two oil changes a year can help keep an old back happy.

In my opinion (IMO), Synthetic oils may offer a lil longer oil change interval but I believe it offers better engine protection. Greater protection when Bo-Bos happen over dino oil.
Here is where I use my common term; More forgiving..

Here is when oil lab reports are a must when extending change schedules and when Bo-Bos happen.
When in doubt, oil labs have better answers.

I think your missing my point.
Yes, My gen-set oil changes are complete in minutes.
Getting the oil & filters in your hands, then on/off the boat and disposal takes time also. Sometimes the worse part of the job.

Do you charge your customers 15 minutes for changing gen-set oil or you add up all the time I'm trying to illustrate.

Yep, for over 6 weeks.
You forget, we don't touch land when we deploy.
Why go into aqua space to get aweigh, and still make landfall to mingle with, what your escaping from.
I had a great visit on a Dinner Key dock.
Two fuel docks.
One barge fuel stop (that was cool).
One waterfront house visit by Mako.
One dock night at Port Canaveral (never again).
One dock night at Safe Harbor, Ft Peirce (maybe again).
Naw, my feet never touched land.

I'm just not a believer in purposefully stretching oil hours in the generator. **** things work much harder than the mains. I'm fine to run 24 hours on one, switching over daily on the long legs of operation. I'll coordinate that with the operational plan for the water maker as to avoid disturbing a cycle of making water.

Water pump...Northern Lights has always shown me to have a fragile water pump that requires a close eye. I keep new replacements on board, not just impellers.

I did not like them years ago but seems they got their formula rite lately;
We have found the later Globe impellers to be lasting much, much longer than the standard rubber impellers and more forgiving to the cam and pump body.
NL pumps luv this impeller.
I would recommenced you give one a chance. I'm impressed.. ☺

Shutting down, starting up, off, on, hot, cool, hot,,,,, These are the hardest times on any engine.
Yes, properly maintained, run them and keep a load on them; 24 x 7 is sweet.
My Kubota just had a problem during our vacation, Frack Me (F M), under-loaded.
All good now.

Now, aweigh from the boat with A/C running? If all hoses and clamps are fresh; Then run the A/Cs also.
Nice and cool when you return from dinner and dancing.

Was shopping for more synthetic oil over the weekend.
Found a familiar brand very cheap. I ordered 6.

Dino oil priced and will run in almost everything but ole Detroits.
Still wish I could find cf-2 40w in synthetic.

Good information. Thank you. Murphy, however, is a strange *******. When you keep the spares aboard, Murphy often chooses to bypass your boat in favor of the one next door...

Yes, I know.
Three boats on our dock. Murphy gets around.

Took your advice and ordered four Globes. Next impeller change is in about 100 hours. Swap them out with two in reserve. Will let you know if my opinion changes from yours...
