Question: what is the difference between white gas and unleaded gas?
Answer: White gasoline is unleaded gasoline with a maximum of 5% of aromatic hydrocarbons and it has 95 octanes. Instead the standard unleaded gasoline of 95 octanes that you put in your car has around 35% of aromatic hydrocarbons (in the USA and the EU) and that is why it is way cheaper to refine than white gas.
