My understanding is that the natural voscosity ranges of synthetics
negate the need for viscosity improvers and hence the wide range
and long drain intervals are possible. I let the Castrol GTX go for
~5k mi in the ur-Q, where I only let the rotten dino juice go 2k mi.
I'll let the GTX go indefinitely in the '84 4KQ, unitl it's down a quart,
then change it, often >10k mi at ~160,000 miles. The QTW gets a
change every spring & fall, regardless of mileage, but well under
10k mi.
