Obviously I misremembered/confused your post with someone
else's. I groups.googled and see your post from a few years
ago where you say you use the Esso (premium in the summer).

There is also no question you have been more meticulous
about your 91 Integra's upkeep than I have with my 91
Civic's. I suppose it's either this or the gasoline or some
combination that have yielded your car's PCV valve staying
so clean. But I really don't know.

I just "discovered" a better junkyard in my area; carefully
organized but customers have the run of the place for a
dollar admission charge. It has several c. 1990 Civics and
Integra. Next trip, maybe I'll pull off a few PCV valves,
noting the mileage of the cars, and see if anything
interesting is revealed.

It was only evident in my Civic's PCV valve in 2003. The new
PCV valve has stayed very clean, excepting my experience
with the STP fuel system cleaner.

I have been under the valve cover several times since
(checking valve lash, replacing the gasket, replacing those
spark plug tube oil seals between cylinder head and rocker
arm), and the rocker arms, tower, etc. look not spanking
clean, but certainly nothing like a sludged engine.

My manual transmissions instructor totally dissed my use of
Pennzoil (exclusively) the other week. Maybe it's a bad
choice. I am not inclined to switch, though, since I have
never seen a consensus against it.

Let me cease to be a hijacker and return this thread to its
original programming. :-)

Do a search on the main relay and you will see lots of comments about
temperature. Hot days really brings the problem on. Good luck.
