That's a poor example really. Those engines are easy on oil and 10,000hrs is just getting broke in. Doing oil changes at 600hrs on them is excessive. Normal drilling rig service they change the conventional oil every 750hrs, and average engine life between major overhaul is 40,000hrs. I've seen some CAT 3512A still running at 78,000hrs with original turbos even. Their service schedule was original rotella 15/40 changed every 1,000hrs. The big industrial engines are well designed to last and easy on oil. Like an oversized Duramax. Lol
Clearly you don't understand the American (aka BITOG) way of life.
If something is good, then more most always be better.
And if more is always better, then more of more must always be more better!
If you change oil more often, then changing it more often with synthetic has just got to be "better than better", right?
You are correct in that the applications they show for the heavy service diesels is a bit skewed in that those engines don't really tax the lube at those intervals. But, I do see value in the video in that the drilling company at least had their eyes opened in two manners:
1- they realized that their service intervals were too frequent
2- they realized they didn't need syns for the service intervals they intended
So not only were they able to double their OCIs, but also lose the cost of syns. That has to be a HUGE savings. And all while still getting the same wear protection and cleanliness.
How did they come to these conclusions? Well, facts and data were used. While we BITOGers don't have a massive lube company sponsoring our cars, or offering to do a tear down of our engines, we can use things like PCs, UOAs, etc to judge the relative health of our equipment.
How is this relevant to the OPs thread?
If he would stop and assess his current situation PRIOR to making an uninformed change, it might just help him save some money and still get great service from his lube.
a) does he even need a syn for his application?
b) what service interval provides the highest ROI while still assuring good wear protection?
c) what product(s) are needed (not the same as wants ...) to get him there?
