I filled my CC 123 up with 93 octane and then started wondering if that made sense for a tractor that was build 50 years ago. Any thoughts on what is best for these old engines?
If the topic has already been discussed please point me in the right direction.

I do also but I also run a lead substitute or a valve saver product. When those engines were designed they were build around leaded gasoline. Unless they have had an overhaul update with new valve seats, etc. I would suggest a lead substitute.

High 89+ octane with no ethanol would be ideal but the non-ethanol isn't available everywhere. We try to run 93 octane in most of our stuff along with seafoam additive.

87 octane and a cap full of Marvel Mystery Oil here. I suspect the compression ratio isn't very high in my old motors.

I worry not about the octane, but the corn content. I shoot for 0% ethanol.

For the last year I have been using 100 octane aviation gas, (Ethanol free) in everything I own and I don't ever have any carb issues anymore. All my Kohlers seem to really like the Avgas. I don't remember if it's leaded or not, will check on next file up.
