One of the very first unleaded non oxygenated fuels on the market. C10 works extremely well in forced induction applications. The higher octane and low RVP have made it a winning formula in a wide array of applications. These include Circuit, Karting, and Motorcycle racing.

NON-OXYGENATED FUEL
tuning info
No added oxygen content keeps fuel delivery behaviour closer to conventional petrol.
Does not require the richer compensation typically associated with oxygenated race fuels.
Still verify calibration with proper AFR or lambda tuning methods.
What is Oxygen Content?
Oxygen content refers to the amount of oxygen within the fuel itself. Higher oxygen content allows more complete combustion, increasing power potential while requiring additional fuel delivery to prevent lean conditions.
STOICHIOMETRIC AFR
14.38:1
98 RON Petrol

C10

Requires Slightly More Fuel Volume Than Standard Petrol
Tuning Info
Stoichiometric AFR is lower than standard petrol, so additional fuel delivery is required.
Still far closer to petrol than oxygenated race fuels, with less aggressive compensation needed.
Always verify calibration with proper AFR or lambda tuning methods.
What is Stoichiometric Air-Fuel Ratio?
The stoichiometric air-fuel ratio defines the ideal mixture for complete combustion. Different fuels require different ratios, meaning fuel delivery must be adjusted during tuning to maintain correct combustion and performance.

C10 0.7650
Pump 98 0.750
C10 is denser than pump fuel, requiring slightly less fuel volume.
Tuning Info
Higher density delivers more fuel mass per volume.
May require slightly reduced fuel delivery to maintain AFR.
What is Specific Gravity?
Specific gravity measures the density of the fuel relative to water. It determines how much fuel mass is delivered for a given volume. Lower density fuels deliver less fuel mass per volume, which can cause a lean condition if not corrected.
Reid Vapour Pressure
4.02 PSI
LOW FUEL VOLATILITY
tuning info
Lower vapour pressure improves fuel stability under heat.
Reduces vapour formation in demanding conditions.
May require attention to cold start behaviour.
What is Reid Vapour Pressure?

RVP Measures the volatility of a fuel and how readily it evaporates at a given temperature.


In forced induction applications, a lower RVP resists vaporisation under boost, reducing the risk of vapour lock. Naturally aspirated engines benefit from a higher RVP, where easier vapourisation improves atomisation and throttle response.
