Moving to Oklahoma soon. Will running their 91 Octane damage my setup?

I know lots of guys who tried 87 octane when they were stock (all had issues), and then I know a few modded guys who tried it as well (the had issues as well, but their issues were bigger ones). Then I know a couple of guys who even tried to get away with just 93 when for their boost level (FI cars) they really needed race gas, and detonation caused them to need a rebuild.
I'm sure you are not lying, but I would never use 87 in a stock car, let alone a modded one. They are high CR from the factory and require premium for a reason (and its not just so the oil guys can get more money).

I work at a part store and when that ethonal come the fuel pump business was booming. It was burning the pumps up.
so where abouth in oklahoma you moving. We got some pretty fast cars here in the tulsa area. So if you want some races we can get some cars togather.

Man, now I'm actually interested in getting it on the dyno to see what numbers I'm makin on this 87, LOL. I can also have my buddy hokk up his EFI live & sit in the passanger seat to see what exactly its doin on the 87. I'm sure alot of people would be interested in those results as well as myself.

Most cars it will eat up pumps, lines, rubber connecters ect. Just generally bad. If you do enough research on it, you'll find that running ethanol to save money on gas is a big crock of sh*t. It doesn't save anything by the time fuel is expended to harvest the crop, and transport it to be refined, and to be refined, and to be transported as fuel. Again, biggest benefactors are the farmers (which I guess they deserve a break, but not at a good cost to us IMO).
Anyways, I'll be stationed at Altus. Doubt I'll be up for beating up on the car much unless I can find some 93 octane. But I might get bored and want to spectate sometime.

butt dynos are not tuning tools and definitely not an indication of picking up the minor power differences of most bolt ons, much less fuel
it is likely either pulling timing or just staying in the low adaptive spark table so the timing is less
so if you hook it up don't just look for spark retard, also look at adaptive spark %
my car would not get over 60% into the performance spark table with a mix of 87 and 91 the 1 time I had to put 87 in it

Ethanol in general unless the car was made for it is bad. About the only good thing its for is the farmers (since ethanol comes from corn, the corn crop profit is sky-rocketing), and for cheep fuel, or if you are setup properly to run E85 it can have other benefits.

See thats what i was told as well, that it would just kick me into a "low octane fuel table". Which like I stated I know is costing me some power. But I did notice a difference between ethonol & non-ethonol gas. Take my word for it or not, doesnt bother me.
But my car went from not being able to break them loose thru third to getting a 4th gear scratch, got better throttle response & picked up a decent amount of gas mileage. This is just what I personally observed happen to the car and I drive it everyday so I notice if its not running smooth. Thats what I meant by using my butt dyno.
It should be noted though at the time I made the gas switch, the pumps were not labeled as to ethonol content levels. this was before that was passed, so for all I know I was getting gas with more than 10% ethonol in it.

lol not much for races in Altus honestly. I lived there as a kid, still go visit the parents every month or so...Altus does have a walmart so you can pick up octane booster as some suggested...I don't know of any 93 octane stations unless there is one on base, there are few non-ethanol stations though.
