NoI have used the royal purple booster from the typical suspects,
but try to avoid it.
During the warmer seasons the station in town sells CAM2 leaded 110 octane at the pump
for $10.99 a gallon. I just mix some of that with 93 octane pump fuel.
So one part CAM2 to four parts premium should put you in the 96 octane zone,
and last quite a while.
