The octane posted on the pumps these days is the average of RON  & MON (research
method and motor method).  RON is approximately 4 points higher than current
pump postings via averaging method.  So, 94 octane posted
is 98 RON.  Sunoco Ultra is 93.5, which I believe is as close as you're
going to find, but it is unleaded.  I've been running that in a Volvo 1800E
which had a 10.5:1 CR before I hopped it up. An occasional tank of leaded
regular mixed in seems to do just fine.  I've seen no problem with
valves etc.
