Octane for a VW?

What octane should I use in my air-cooled VW engine (vintage about 66-67)?

Thanks!

As expensive as it gets. With a 10-13 gallon tank it isn't worth buying the cheap crap that makes your car fart. Spend the extra buck and go 92-93 octane. I remember Carlisle when I bought some cheap crap and it took 2-3 tanks and some carb adjusting to get it to stop. Never again my friend.

Or, you can go the "it depends" route..........

If it is a bone-stock VW engine with no "go-fast" work done on it, it should be quite happy with 89 octane......

I ran 92 octane in my 9:1 comp motor, and it ran great. Could I have gone with a lower octane grade? Sure, but is it worth the wextra few cents and worry? Stock comp? Then go with the 87-89 octane.
Remember, these motors don't have knock sensors.

Thanks, guys! I put premium gas in "Schatze" and she runs better already!

It's a shame no one has came up with a way to have a knock sencer kit for the .oo9 that would self ajust using a vacum advance and a electric air soleniod . But it should be possible.

But there again, to much plumbing stops up the drain!!
