For years, we religiously ran VP C-16. But with it's price now soaring above $21 a gallon here locally, a lot of people are converting to alky with a booster, or E-85. I currently run Shell 93 with 1 can of VP Octanium on my car with alky and it's done just fine. However, there will come a point where higher octane with my tuning will be needed.
Leaded race gas, here's my list.
- VP C-16
- Torco 116
- Rocket brand 116
- Sunoco 114
- Sunoco 110
The highest hp v6's in the country, typically run C-16 or the oxygenated Q-16, if they race in a class that requires gasoline fuel.
Octane boosters:
- Boostane
- Octanium
- Torco
Torco being the harshest of the 3 on leaving deposits on your plugs and O2 sensor.
You can buy VP Octanium at all Autozone stores.

When I ran pure C-16 on a stock engine combo, I ran the OEM replacement Bosch O2. It would live for about 3 full tanks before I started to see it slow down / degrade. A heated O2 will give you a little bit of extra time, but not worth the extra price IMO.
Unleaded race gas is the 3rd option:
- VP-109
- Rocket brand 110
- Sunoco 100
The biggest advantage of leaded race gas / highest octane, is the ability to run very high boost levels (35-40psi) with high timing and hardly ever seeing knock retard. You gotta be careful though when you run the lower grade leaded race gas, as your tune will vary. IE: going from C-16 to say Sunoco 110 / 114.

Oh well. Good to know that it is available.
