A oxygenated fuel blend that offers more protection and consistency than any other unleaded racing fuel on the market. QM25 was manufactured with one goal PROTECTION.

It provides racers with the peace of mind at the race track. QM25 was not formulated to make maximum power.

Racers looking for more power should consider using MS109 REG, or QM106.

MODERATELY OXYGENATED FUEL
tuning info
Moderate oxygen content improves combustion efficiency.
Requires a slight increase in fuel delivery.
Less aggressive adjustments compared to highly 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.

13.86:1
98 RON Petrol

Requires Slightly More Fuel Volume Than Standard Petrol
Tuning Info
Lower stoichiometric AFR requires additional fuel delivery versus standard petrol.
Closer to pump fuel than highly oxygenated race fuels, but tuning adjustment is still required.
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.

QM25 is closer in density to pump fuel, requiring only minor adjustments.
Tuning Info
Specific gravity affects fuel mass delivered per volume.
Only minor fueling adjustments are required compared to pump fuel.
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
4.01 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.
