Amsoil recommends a 1000 mile max interval with this oil and the tbn is only 0.45....
Something else to keep in mind is that the truck gets nearly zero miles since it is a yard truck only. 100 miles in a year is a BIG year, so I can't go by miles. Even 500 miles would take me several years. I go through about 100 gallons of fuel a year usually, but hardly any miles.

If not for the cold I might have done that. But I went for the cold change and tightened the header bolts while it drained. I'm glad I did after seeing what came out.
All the swirls in the oil were shiny and the oil in the pan glittered in the light. Also, this pic was taken after dumping from the red pan and walking away for over a minute. This stuff was so thick that it wouldn't even flow into the drain holes of the drain pan!
I'm glad I changed it out. And the new oil has plenty of additive to take over.

Maybe I didn't report back, the springs are only a few pounds heavier than the Z28 springs once calculated for the correct installed height. So not as bad as initially thought.

Yeh, and replace that daft-and-destructive mini-spool thing with a split handbrake (That was you, wasn't it?)
And paint your diff case, say, green.
Oh wait, you didn't ask about that....
Nope... not me. Factory G80 gov-lock on board here....
