We run more because they’re air cooled gas motors. Water cooled doesn’t need nearly as much unless you’re on alcoholI keep hearing that 8oz/1gal is what you want to mix on a KT100. I’ve always ran 32:1 4oz/1gal, on 2-strokes. Is 8oz/1gal necessary? Thoughts?? I plan on using Klotz or Blenzol.
Now that’s interesting!!I did a test once using my direct-drive Yamaha kart -- just kept adding oil. I was using Castrol R-40 at the time.
Bottom line: the more oil I added, the faster the kart ran (in lap time) -- right up to the point where it became difficult to not foul the spark plug, which happened at about 16oz/gallon.

Hey Pete , what do you think is causing the performance gain , anything beyond just ring seal ? Maybe a lot of residual oil starts running the compression up, something at work there evidently.
Wow! That's tight.Btw: On my direct drive Yamaha, I set that up with .0005" skirt clearance (yes: half a thousandths).

The more oil you add the leaner the fuel mixture.My gut feeling is that the entire piston is sealing better which might be improving the crankcase pumping efficiency. It's only a guess though.
