Oxygen content

MODERATELY OXYGENATED FUEL
tuning info
Moderate oxygen content improves combustion efficiency.
Requires a small increase in fuel delivery.
Less aggressive tuning changes than high-oxygen race 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.
STOICHIOMETRIC AFR
13.72:1
98 RON Petrol
14.7
MR Pro 6

Requires Increased Fuel Volume Compared To Standard Petrol
Tuning Info
Lower stoichiometric AFR requires increased fuel delivery versus standard petrol.
Moderate oxygen content may require additional enrichment 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
0.7250
0.70 Specific Gravity Comparison 0.80
MR PRO 6 0.7250
Pump 98 0.750
MR Pro 6 is 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
11.01 PSI
HIGH FUEL VOLATILITY
tuning info
High vapour pressure increases evaporation and responsiveness.
Improves cold start and transient fuel behaviour.
Monitor heat conditions to avoid vapour-related issues.
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.
