How hard is it to find 91 to 94 octane?
I'll keep this brief. Going on road trip from Victoria, BC to Redding, CA - will be passing through WA, OR, CA. Currently, my Miata is tuned for 94 octane but I will probably be lowering that to 91 assuming 94 will be impossible to find.
Question is: (a) Is 94 impossible to find? (b) How readily available is anything from 91 to 94 in those states?

The Lucas octane booster actually works:

Buy enough bottles to mix up 50% more fuel than you think you need and let it ride.

Oh shiz. I got the car tuned for 91 octane today, still have yet to take it out on the road and actually fill it up with some 91, but we basically added a bit more fuel and brought the boost down from 12 to ~10psi.
I'll pick up some octane booster just in case anyway. You guys in Cali don't always run your cars with octane booster, do you?

No, they just tune for 91 I'm assuming. We're telling you to run the octane booster since it'll be easier and probably safer.
We have 93 here in the Portland area, but I'd suggest filling up south of here in either Wilsonville or Woodburn. Both are right off the freeway, have plenty of places for gas, and avoid the busy cities.
If you fill up in Seattle, then top off in Wilsonville, you should be able to make it down to Grants Pass, then you're only one tank away from Redding.
This is assuming you can get 200-250 on a tank.
edit: And I list Seattle and Wilsonville cause they have 93. Dunno about GP.

Thanks guys. This all really helps.

EZ lazy and effective fix is to log into your tuning software and subtract
1* at 5psi
2* at 8psi
4* at 12psi
5* at 16psi
Interpolate and prepare for slow. Your AFRs will be off by a bit but in the rich direction.

But mixing a concoction of booster/pump gas and hoping it will be somewhat close to what you're tuned for is a recipe for failaidz.
You could run more, even on our camel **** 91, but if you're on a road trip I don't think puttin down every last hp is your 1st priority.

Apparently my car is a tank. Assuming you're talking 200 miles, I think the best I have gotten is around 350 km on the highway and mostly saying out of it.
So it seems to be 50/50 between people that think octane booster is worth it and not...

octane boosters are a joke. You need to uy like ten 16oc bottles to bump up the octane. There are easy formulas on google.
if anything you need a gallon can of toulene or xylene. Go see your paint store.

I used to think they were all snake oil (and for a very long time, they were), but the Torco and Lucas octane boosters are legitimate. A 100:1 ratio of 93 and Lucas makes and honest 96+ R+M/2 octane. Read the article I posted. Dude measured them with lab test instrumentation, then confirmed with a knock engine.

That said this wouldn't be very difficult to test without any meters. Tune your map til it knocks. Back off 2 degrees. Add bottle. Add two degrees, see what happens. The end.
No, light pinging will not be the end of your motor.
