I have been looking for a real, viable gasoline additive that I can use in my 300SX's to supplement our only 91 octane (R+M/2), non-leaded, non-ethanol gas available in Oklahoma to get to 93 (R+M/2) . I have researched most octane additives currently out there. All, in my opinion fall short. They state they can raise pump gas by "x" points of octane. Note that a point of octane is only 1/10 of an octane rating number in R+M/2 rating. So, 10 "points" only raises our 91 to 92 octane! Don't believe it just read the 'fine print" on the current offerings! Looks like the below link is the real deal! Anybody try this stuff yet?

I didn't read it all, 32oz treats how many gallons

check out boostane

Splash some 110 it smells So good!

I agree check out Boostane. Also the guys on S&F have been running a product called ACES. I have used it for years with no issues. One ounce treats 6 gallons.
Chris Carson and DBR both 2 stroke engine builders have tested it and said it works. It really does not increase octane but lower the combustion temp.
I can get you the number and you can speak wth him about. I do not remember all the details as it was a long time ago when I spoke to him.

RACE GAS
BLENDING CALCULATOR
2 OUNCES OF RACE GAS
WILL RAISE THE OCTANE OF 1 GALLON OF GASOLINE
4 FULL OCTANE NUMBERS (40 POINTS OF OCTANE).

Use the calculator below to determine the appropriate
amount of Race Gas to add per gallon:

1 - GALLON FUEL

Some testing that my shed some light on the snake oil. I believe the ACES IV is a good product to enhance the characteristics of gasoline and I do use it.

I thought about doing this but wasn't sure if it would be safe for my 500efi's. I use to run it in my motorcycle. And if it is ok what do u do like one gallon to a tank full.

VP C5 booster you get 3.3 double it and you can get to 8.0 But you will need a lot of timing to make it burn. not sure if its worth the retuning

2 ounces per gallon
gets you 4 points.

$29.95 for 32 ounces.

100 gal fill up of 91 would be $89.85 to get to 95 octane
