I changed not because I thought it was used up but because it had been 2.5 years.
Clearly I can go for very long OCIs.

I'd stretch it to 4 years and uoa for TAN. With that kind of make up oil you'll probably never run out of TBN.

Hi Charlie,

a great UOA - yes, your OCIs could be extended too

My very kind regards - coming back to OZ anytime soon?

Doug,

Not exactly soon but maybe after a generally eastwards trip through
Europe, Israel, Russia, Mongolia, China, SE Asia...
Shipping to and from Australia was more expensive than shipping to and from Europe by a factor of 10.

I cannot agree with you any more than that!
Very low wear.
Very low contamination.
Excellent TBN/TAN relationship.
etc,etc ...


Extended OCIs are very much a reality here. 2.5 years and this is the result? Excellent example of how the clock is NOT a tool to change oil.

Obviously, Charlie is very-well versed in his application and will not extend without UOA confirmation along the way, but I see LONG OCIs if this is indicative of the performance.

This being the result, I would think even longer use would be something to consider.

Conventionals vs. Synthetics isn't about which is "better"; it's about which lasts longer, while assuring safe operation, in relation to cost. Any product can be over or under utilized. The same applies to filters.
Make an informed decision; first consider your operating conditions, next determine your maintenance plan, and then pick your lube and filter. Don't do it the other way around ...

I think my plan will be to sample this new oil change at 20K and then every 7.5-10K thereafter. The limiting factors could be Fe (the limit on the engine is 200ppm) or viscosity, I doubt it will be TBN.
