Debate that............. Lets have some dissension among Rocket Captains and Rocket Privates (I did say that).....
I burn the cheap ****te. It's a relatively low compression engine with advanced electronic controls and (I presume a knock sensor) so it should be able to compensate for low octane swill. Saying that, I don't know if it would run on Pemex but then I'm not planning any Mexican junkets in the near future anyway.
Now, if I decked it and added high compression pistons or a turbo or Roots type supercharger which would raise the theoretical compression ratio (not both together), then I'd opt for Super Blue or Av. Gas but being what it is, a large displacement lawn mower engine, the swill works fine. Besides, I use the difference in monies to buy Marlboro Reds.
Even my air cooled twin cam Bonnie runs on swill and it's only electronics are the igniter box and the carb heaters.
If it's good for the lawn mower, it's good for the Rocket.
