But bear in mind, a fuel's ability to prevent detonation is a function of more than just octane. For example, VP's fuels - oxygenated or nonoxygenated - vaporize much better than competitive fuels with comparable octane ratings. This means VP fuels cool the intake charge, burn faster and yield more efficient combustion.

MOTORSPORT 100 is a VP 100 octane fuel. We design it as a professional-grade, unleaded blend for all forms of motorsports. Moreover, it's a spec fuel for IMSA sports car racing in North America.

C12 VP Racing Fuel The best all-around racing fuel made. Recommended for CRs below 15:1, satisfying the needs of 75% of today's race engines. One of the winningest fuels in racing history.

VP Racing Fuel - C14 114 Motor Octane Leaded N/A High RPM Engines 5 Gallon Pail.

We design VP C10 as the best non-oxygenated unleaded racing fuel on the market. To begin with, it does not contain any metal compounds and will not harm catalytic converters or oxygen sensors. Furthermore, it has a proven performance record, which includes numerous past SCCA and Ferrari World Challenge championships.

Bottom line: VP's C12 is the winningest, high-octane, two-stroke racing fuel in motorsports history; however, it is too cool for stock powerplants.

C16's octane rating is actually 117, and you'll know it by its blue hue. Rueckert says C16 works very well in non-intercooled supercharger and turbocharger combinations where there are elevated intake manifold temperatures.

VP C14 is a spec fuel for NMRA and MMCA. Moreover, it's been a dominant fuel in NHRA Championship racing for decades. We recommend our C14 fuel for high RPM engines with ultra-high compression ratios over 14:1.

97 octane rating T4 Racing Fuel is the perfect solution for 4-stroke engine needs. Unleaded and ethanol-free, it contains a 97 octane rating (R+M/2) which improves protection against detonation, delivering up to 2-3% more power and better throttle response than standard or premium pump gas.

F1 cars currently use an E10 fuel, which is 10% ethanol.

E85 fuel can give you a significant boost in power and torque without breaking the bank for racing fuels. It has a base octane rating of 105 and has the bonus of added cooling properties that add even more knock resistance than racing fuels with the same rating.
