What evidence do you have that it makes that difference? None, I
suspect, since none exists. I've owned three vehicles that went over
165K miles and all of them ran fine. Their oil was changed every
5000-7000 miles. They were all put to rest for reasons other than engine
problems (body rot, broken transmission, etc.)

Because the benefits go on a curve.

And when you run your car like a taxi, 24/7 with the engine on, those
tests will be relevant to you.

If you drive your car like a stay at home mom, a couple miles here and
there with the engine never getting warm, that would create different
results.

Did CR test those kinds of conditions?

You can't extrapolate the CR taxi test into the normal world where cars
aren't run like taxis.

You asked someone to show you something that could break inside the
engine due to insufficient oil changes. From that page: "If the owner
had left it long enough, the pickup would eventually have choked on the
sludge, causing oil starvation and engine seizure."
