What oil for 12v71 DD's?

[Bubba Bert]

What oil do you run in your detroit's? I've seen so many brands and weights thrown out there, I'm confused. We really don't get "winter weather" so I assume my block heaters will be more than adequate.

What oil has been in her , some people don't change brands/weights.

She was in Topsail, NC. Before I bought her. Different conditions, hence the question

When I was in marine diesel repair school, about 30 something years ago, not only did we get our hands greasy, we did some research Chevron Delo 400 met all manufacturers and military standards. I have been using it in all of my engines since then. I tore an older engine down for rebuild with over 11,000 hours on it, always used Chevron Delo 400 and it was clean as a whistle.

Bubba,

I have seen a wide range but no clear cut favorite in my area (Orange Beach).

Jason, do you work with my mom Sandra? But anyways I am a diesel tec. what we allways use is Rotella!

[Jason@GalatiYachts]

Yes I do she is the greatest.

We used Delo 400 by the drum for all of our 71 series motors. Rotella 30 wt is another good one, don't think it is the same formula as the newer Rotella T for small trucks.
