Many things can be easily surmised. Sometimes correctly, sometimes not.
There's a lot of conventional wisdom out there - usually based at least
loosely on truth. Sometime, however, the conventional wisdom outlives the
I wonder if this is one of those cases. Is it possible that modern oils,
with their vastly improved anti-corrosion capabilities (as one example) have
made the speed of the warmup of less importance?
For some antecdotal evidence, which certainly proves little, my thermostats
died about 20 years (say 140K miles) ago. At that point the doors stayed
open. At some point I removed them. I replaced my rings some years back,
probably about 40K ago, so the replaced rings probably had 100K on them. I
have never had any blowby problems.
I drive hard. My daily commute has varied from 15 miles to 8 miles to 14
miles each way, depending on my job/house location. The car is seldom
driven if the temperature is below 40 degrees, since it is seldom that cold
here. 140, 4 spd, .040 over, step cut on heads with no cuts on pistons to
lower compression. Oil changes - seldom, but 1qt added per 1000 miles (my
engine always leaks, no matter what I do). Filter changes more often. Dino
oil. Air cleaner usage intermittant. Not exactly textbook maintenance, but
no sign of oil related problems except for the oil soaked cardboard on the
