Fuel for petrol engines
Petrol also known as Motor Gasoline or gasoline is a product derived from crude and used as fuel in internal combustion engines. This fuel is for spark ignition engines like car engines. In some countries Gasoline is mixed with ethanol at some predetermined ratios (like E10 for 10%) and used as an alternative fuel. Gasoline is more volatile than Diesel and Kerosene and hence needs extra precaution on its handling. Octane number ,Vapor pressure and sulfur content are some of the defining characteristics of this product.
