Don't worry about the octane. You will set the timing to make it work. The big problem in converting is you are going to have to remove the entire fuel injection system. You will have to find a vaporizing carburator that you can adapt and you will need a vaporizor/pressure regulator in the cooling system to feed it. The other big problem is where to put the storage tank. The obvious place is where the gas tank is but then you will have to extend the fill valves so you can reach it. You will also have to figure you will not get the range or mileage you can get with the equivelant amount of gasoline. I would not know how you could make it "dual fuel" so you can run gasoline OR Natural gas. In this case if it is ONLY natural gas, if you run out you are dead, most stations (at least in the US) do not sell natural gas so you may be severly limiting yourself. Natural gas does not like cold weather, how cold does it get in Poland? One BIG advantage natural gas and propane has (at least in the US) is that there is NO road tax on it which makes it MUCH cheaper. Just tell them you are filling your tank for the gas grill if they ask!
