i think you still have a way to go.

Wow... I tend to keep the Gen II Civics below 3K (rpm)s. A lot of
things can be factored in over time including metal fatigue, ka pow!

When you finally retire it, do so with ceremony...

What has that got to do with the question I asked. You said compute mileage
over a 3000 mile interval. Are you saying you "top-up" your gas tank once every
3000 miles?

For some reason you seem to comprehend that measuring gas mileage over small
disjointed intervals would produce inaccurate results. For some reason you
can't comprehend that measuring over small disjointed intervals is even more
inaccurate for determining oil usage.

Do you think I was suggesting your car behaves differently because it knows
your mother is sick?

What your engine did seem to notice was how long you left the oil in this
summer. In case you didn't know there is a very definite relationship between
how much oil an engine uses and how long the oil has been in the crankcase.
This relationship is usually very evident in an engine with more than 300k
miles that is starting to use some oil. That relationship is the exact opposite
of what most your data shows (up until this summer) , which is why I know your
data (up until this summer) is bogus.

Actually, the transmission gear ratios are the same through all models of
the Integra for '90 and for '91. They are different from automatic to
manual, though.

but different ratios are apparently available:

Apparently so, but they all shipped from Suzuka equipped the same way.

Wish I'd thought of asking years ago if there were a taller 5th available.
I see the site you reference shows the B18B as having shipped with taller
5th and diff ratios. What's that, about 7% taller overall than the ratios
listed for the USDM B18A? Not a lot of difference. I'd get 3,880 rpm
instead of 4,000.

Then there's the question of whether the listed gearsets are even
compatible between trannies.

I'd guess the aftermarket also makes gearsets with custom ratios.
