Check with some of the gas companies like Sunoco, Trick, and VP fuels. They have outlets all over. There's a station near me that sells Trick 101 for about $5.60 a gallon. They are many stations like this.

If you use enough, you can get 55 gallon drums delivered two your house from most vendors. They deliver for almost free if you buy 2.

Streetblaze 103 is the highest street legal unleaded fuel you can get and it's pretty damn good. Not sure how good you'll do NA but it's fantastic for FI

if memory serves it's about $7 per gallon, check their web site for dealers.

I'm running 91 but with Water Methanol injection which has the same effect but it's cheaper especially since I only spray if I need to since it's boost driven

There are some 76 stations around So Cal that offers 100, but it comes around $6 a gallon. On race days, I usually mix about 25% 100 with 91 to get somewhere around the ball park of 93.

There is a noticable difference on how the engine feels, its alot smoother and doesn't feel so rough when you go through the rpm range. You usually get about 7 RWHP gain on the dyno, but not much noticable difference on the 1/4 miles.

Kinda pointless unless you are running a really agressive tune.

In the late 90's, when premium 92 octane was $1.40 a gallon in So Cal, I said I would never pay $3 a gallon for Unocal 100 octane gas. Now I am paying >$3 for 91 octane gas...

According to VP, the MS 109 unleaded is "street legal" also... That's what I run in my hi-comp 20v. Never seen it at the pump though...

so high octane gas doesn't really help performance on NA cars? no point in me wasting tons of $ if that was the case. Just wanted to try it out..

It does if you have an aggressive tune or have extremely high compression that needs it. Other than that it is unnecessary especially on the street
