Nobody really answered this from my earlier post about the catalytic
converter.  It does not specifically state what gas to use in the Vanagon.
The manuals seem to act like I am supposed to know.  I have been using
mostly ARCO regular (octane 87) and it seems to be doing fine except for the
degrading converters but I don't know that the two are related.  I know that
alcolol in the gas can be a problem.  What about oxygenated fuel?
