The names of these things varies a lot from country to country. They use the word benzine in Iraq for the normal fuel for a car, which we call gasoline in the US and they call petrol in the UK. We have something called benzine here but I don't know if it's the same as your benzine, and I don't know where you are (Italy?). Certainly don't use gasoline for cleaning your bike, because while it works well, it's unnecessarily hazardous.
