Yes, I agree. I've been burning the cheap stuff in my cars for a long time. I tried tanks of the expensive stuff here and there on different vehicles to see if they got better mileage or ran smoother. I never saw any appreciable difference in mileage or how smooth the vehicle ran. I stopped buying premium for my cars over 20 years ago.
I only asked the question about gas for the 600's as I have no experience with running small air-cooled engines. ;o)

As has already been said, using a higher octane gas will do NOTHING for your engine. It doesn't clean it. It doesn't recharge it. It doesn't do anything magical or mystical.
Higher octane is designed for engines with higher compression. The kicker is that now adays these higher compression vehicles will self-adjust their timing to compensate for lower octane gas.
Anyway, when I was 18 I thought that 92 Octane was higher quality gasoline, which is what I imagine most Americans think. In reality, however, it isn't.
Unless you have turbo-charged your n600 or maybe dropped in a honda b-series engine, I would not use anything lower than the lowest octane gas...
unless you enjoy wasting money.
What flavor gas do you use in your 600?

Re: What flavor gas do you use in your 600?
Yes, it does make a difference in modern engines.....sometimes. If you are
not doing extreme driving (high altitude, heavy hauling, hot temperatures,
climbing steep hills), the ignition advance system on modern cars has
plenty of variance to compensate for engine knock. The mfg is telling you to
use a particular octane level because they know what their engine needs for
worst case conditions. If you use lower octane gas and start pulling a boat up
a steep hill, the engine will knock and the electronics will not be able to
compensate....it will not have enough range.
Since you are not having any problems, keep using regular. If you are
going to subject the vehicle to extreme conditions, switch back to a higher
octane blend (and make sure your fuel gauge is near empty so the higher octance
level is not being diluted too much by any residual regular gas.
