What type of gas are you running your Forza on?

I see the manual calls for 91 octane (premium).

Can regular 89 octane be used?

My Owners Manual (pg. 33) says to use 86 octane or higher. I've been using 87 octane.

I don't know why, but the online manual says to use 91 octane.

Happy to hear that it runs on the cheaper grade!

Given how little gas these scooters take, it seems a minor quibble. The difference in a fill up will be... what... fifty cents?

Use what the manual recommends for your country.
Octane ratings are not the same across the world.
As for the old question of is a higherrating better, then no, for a scooter there is absolutely no benefit whatsoever using a higher rating than the one listed in the manual.

Doesn't hurt either and doesn't break bank to use higher

Depends on what you mean by doesn't hurt.
If you want less power, worse fuel consumption and a risk of burning your exhaust valve, go right ahead.

Premium is not Avgas.

An understanding of how octane works will put an end to a lot of questions like these.

I just like fuel without ethanol. To get that, I have to buy premium.

Ethanol is great for the environment and jobs for North America were less dependent on the oil country's , also ethanol is usually higher octane but it's corrosive , (most newer cars and motorcycles can use up to 10% ethanol in the gas,)less power per volume,so less fuel economy and some says it doesn't store as long

North America only. It's always about us...... :lol: ;)

Let me see if I understand this,
Add 10% ethanol reduces my mpg approx 10%, so I have to burn 10% more to go the same as before?
I am now burning ethanol which I didn't before and this helps saves the environment?
By diverting a food product to gasoline, I guess this will help the hungry?
It deteriorates auto components faster thus raising the cost of ownership while increasing the parts requirements that otherwise would have been less?
So farmers are subsidized and by increasing consumption, tax coffers are increased.
Did I miss something?

Nope that's pretty much it. Oh wait,...this Ethanol thing is mostly politically motivated.
You did forget to mention that. ;)
