in md its 87 89 91 or 93 lol

 

Thats what I used to run in my high compression big block. I use Sunoco if Shells not around.

 

Well sunoco is no more here, Petro and sunoco merged and now Petro sells ultra 94, at least in Ontario... Been using it strickly with no issues at all

Octane boosters can definently help, but I see it as a more if I get stuck up north with 91 octane only available...

A good read about octane boosters and which to and not to buy

Good formulas for octane boost

 

Great info indeed... just not 100% sure about doing the mixtures... Whats the worst that can happen with a bad mixture??

 

Explosion

 

Well that could be good as long as it aint pre-ignition or detonation lol

 

I hate you all...I live in california so all we have is 91...or pay 8 bucks a gallon for 98

Anyways, like the OP, I wanted more so I played around with all the off the shelf stuff. the NOS one seems to work if I stick in 2 canister per fill up...but that is an extra 30 bucks a tank. At that point, might as well pay the 8 bucks a gallon and just get the 98 octane race fuel.

 

Mam, I'm pissed. Great Falls, MT only has max of 91....wtf....though I did find a suspect E-85 station . I guess it'll be time to upgrade injectors and fuel pump and find a freaking tuner in the area. I def don't want to run that stuff w/o a tune.
