VR6 runs reasonably well with any octane fuel from US gas stations.

Still, there is a noticeable perfomance difference between 86 and 92
octanes.  I checked the gas mileage, too, and it appeared that it got
significantly worse as I was using lower octane fuel (so much for the
savings from using cheaper gasoline!).

Furthermore, 92 octane fuel is supposedly cleaner.  A friend of mine, who is
into car racing, claims that at-the-pump cost is offset by the long-term
cost for maintenace of fuel injectors, pistons, and other internal engine
parts that get clogged up with gunk.  Kinda makes sense, but I don't know if
it's true.

A sticker on my fuel cap says something like "91 or higher octane rating
recommended".  So, for now, I will keep using 91 and 92 octane fuel, unless
someone convinces me otherwise.
