It's a gas! ... question... - LucienLeFranc - 03-31-2026
Had to fill with 91 octane premium ethanol-free gas at my local puregas station, since it's not permitted to fill a vehicle with zero-ethanol "regular" (87 octane) here in Oregon. Owners manual seems to say no problem with higher octane gas, correct? It only specifies gas needs to be over 86 octane, no upper limit, though?

Correct.

What?

The powers that be have decided that regular-grade puregas (87 octane nonethanol) not be taxed in the same way other pumpgas is taxed. So, if you pull up with your bike for a fill-up, your only choice is premium-grade puregas, which is taxed.
The intent, I think, is to have a puregas option for lawnmowers etc. that is not taxed, which is a good thing?
The other option is to fill a gas can with regular puregas and then use the can to fill whatever you choose. The attendant told me that he's seen guys show up with 50-gallon drums to buy regular puregas "for their lawnmower," wink wink.

Strange. I have not come across this yet filling either vehicles or motorcycles.

I haven't seen it here either. We have off-road diesel available a little cheaper than on-road, but I haven't seen that sort of thing in gas. The vendors near me that offer ethanol-free gas all sell 90 octane. The marinas also sell ethanol-free, but I can't remember the octane.

Only if you patronize a station that sells regular (like 87 octane) clear gas and try to fill your road vehicle's tank with it would you be aware of the prohibition.
My usual clear gas station is Gill's, which offers both premium 92 octane and regular 87 octane gas.
If I pull up on my CB, they will happily fill my tank with premium-grade clear gas, and I'd ride off none the wiser.
Likewise, if I show up with a gas can, they will happily fill it with regular-grade clear gas, and I'd drive off none the wiser.
Only if I ask them to fill my CB tank (or any other road vehicle's tank) with regular clear gas will I be denied.
See section 3c here...

...or just call and ask a station that sells regular-grade clear gas if you can fill your CB's tank with it, for example, call Gill's:

In Ireland we have one single Petrol (Gas) Octane so nobody takes any notice of what that is. All cars and bikes from every manufacturer are good for it. It is also E10, no option for anything less, that is it. Lucky you get to choose :-)
