This is correct... I remember reading that these points are in decimal.Octane Boosters like Liqui Molly only improves Octane number by 0.4 octane numbers. They will advertise it as 4 units. But 10 units is equal to one full octane number. Those companies will never tell you this. New Civics Can run on 92 euro 3 petrol ECU will adjust ( I have used it without boosters ), But it is not recommended in long term.
