What's the best fuel for our cars to mix with 91 octane?

Been thinking either MS109 or GT 260 plus...

Need to buy 5 gallon drums for my next track day.

Thanks

are you tuned for race gas? or are you just wanting it to prevent knock?

Looks like Sunoco is top tier, VP isn't.

i think thats for pump gas, vp only sells race fuel iirc.

Ive used VP 103 octane and really enjoyed the ass kicking i did lol.

ahh i dunno if i would call either of those race gas(certainly not 93) but if you are wanting to run a 100 octane file you would probably need something like 115octane to mix with the 91.. if you want to run 93 then 100 octane mixed with 91 will be good.

However if you are wanting to run 100 octane tune with a mix of 91 and 103 you will be under the octane curve making like 95 octane... so you gotta go higher in my opinion if you want to run 100 tune blended.

or completely empty your 91 and fill up with the 103 cans and run your 100 octane tune.
