Which of the two Fuelx products would give the higher octane for the same amount.
For higher octane increases you will need Ultra 110, which will give for street use will give you 6 ron when you add 1 litre to 50-60 litres of fuel. You can add more for race or drag applications
The Race formula uses a similar ratio (5ml per litre) but it does not give a octane figure.
