This is a very a complicated process.
There are two versions of the octane rating system.
Neither I nor you will be able to calculate octane because of the cost prohibitive tools needed..
it means that the knocking property of petrol is equal to the mixtureof 60% n-heptane and 40% iso-octane.
petrol contains octane :}
High octane gasoline (petrol) only provides better fuel mileage in vehicles that require the high octane. In a normal engine running higher octane provides no benefit.
No, it is not possible; also octane is not soluble in water !
Answer It is to do with the octane levels in the petrol. the higher the star the higher the octane. It used to be 2,3 and 4 star but now its mainly unleaded.
Petrol (gasoline) usually has an octane rating. It is a mixture. Since Octane is C8 a molecule of petrol (gasoline) contains approximately 8 carbon atoms.
Octane is obtained by distillation from petrol.

I would use the lower octane unless the vehicle "pings" excessively and if so use the higher octane
The octane value of LPG is usually regarded to be 100 to 105 RON. However in some cities it can be as low as 96 which is the same as super grade leaded petrol. No additives are added to LPG to increase the octane level. It naturally is a high octane fuel.
Many use standard petrol, some use high octane petrol.
because the petrol is to dirty or low octane
