Not so.
I run regular octane fuel in both of my busses, and they run fine!
I was surprised when, after running Casper on Hi-test for many years,
I discovered he was all OK with regular octane.
-but-
When I rebuilt the engine on NeueBus, I increased the combustion
chamber a bit, and lowered the compression ratio just a bit, as well,
so that regular octane would be acceptable.
With my conservative driving (slow) and the Hull unit electronic
ignition set pretty far advanced, I get 22-23 mpg consistently, and
never a ping.
In the higher altitudes, (+5,000 ft) I know for sure that the timing
will need advanced, and I could possibly discover that the higher
test fuel will again be needed.
Here at 550 ft - 1250 ft altitude, I have no problem.

Absolutely do not run regular gas in an aircooled VW engine. You
will give your mechanic a heart attack. You need more than 90
octane in a VW engine.
