Longest OCI on a Gasoline Auto Engine?

[wn1998]

What is the longest OCI on the board without a bypass system?

there was a guy who ran amsoil in a chevy trailblazer for almost 25k. what was impressive, he did it right after he drained the factory fill. haven't heard from him since.

Olympic is shooting for 80,000-100,000km in his Montana minivans using Esso XD-3 0W30 motor oil.

The 40k km UOA came back with the oil 'like new'. 100,000km = 62,500 miles.

My son-in-law just did his third oil change in his GMC Dinali comething or another at 70,000 miles.

I think it's 15k here and 20-25k mi. on some newer VW/Audi's in Europe ONLY with specific oils.

The longest non-bypass OCI I can remember here was around 16k miles in a Nissan.

The general extended OCI's seem to be between 10k and 15k without a bypass setup. Usually the UOA's look pretty good and point to the fact that the oil could've made it longer.

30K on conventional oil in a company car. I think it was a Lincoln Town Car with the 4.6 Liter.
The TBN was completely depleted, but the oil was still lubricating and the wear metals were slightly high, but not catastrophic. Then again Ford's modular motors including the 4.6 liter seem to NEVER show high wear numbers.
It's somewhere in the UOA section.

I lied.
Here's the thread and UOA: http://theoildrop.server101.com/cgi/ultimatebb.cgi?ubb=get_topic;f=3;t=000949#000000

It was 26K on unknown brand 5W30 in a 2001 Lincoln LS. I believe that is probably NOT a record-setting OCI, except that it was on $1.75/qt or less convetional oil in a passenger car.

Heck, if those things have the 3.4 Liter 60-degree V6 I think they do, the limiting factor on OCIs may be intake gasket leaks.
