HIGHLY OXYGENATED FUEL
tuning info
High oxygen content increases combustion efficiency and response.
Requires increased fuel delivery compared to standard petrol.
Fuel volume changes are more aggressive than moderately oxygenated fuels.
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.

Requires Increased Fuel Volume Compared To Standard Petrol
Tuning Info
Lower stoichiometric AFR requires increased fuel delivery versus standard petrol.
High oxygen content further increases fuel demand under load.
Use lambda for accurate tuning across different fuels.
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.
SPECIFIC GRAVITY
0.716
0.70 Specific Gravity Comparison 0.80
C50+ REG 0.716
Pump 98 0.750
C50+ REG is significantly less dense than pump fuel, requiring increased fuel volume.
Tuning Info
Lower density delivers less fuel mass per volume.
Increase fuel delivery to maintain correct 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
10.33 PSI
HIGH FUEL VOLATILITY
tuning info
High vapour pressure enhances evaporation and throttle response.
Supports strong cold start and transient fueling performance.
Monitor temperature and system conditions to manage vapour effects.
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.
