What is the difference between unleaded gas engines and leaded gas engines?

Engines built to use leaded gas generally had higher compreesion ratios that made them more powerful. Unfortunately, the higher compression ratios need higher octane ratings to avoid detonation or "knock." These higher octane ratings in gasoline were achieved by adding tetra-ethyl lead to the gasoline. Lazy engine designers also started relying on the lubricating properties of the lead to reduce engine wear, so these older engines may be prone to rapid valve-seat wear even if you feed them high-octane unleaded.

What is the difference between unleaded and leaded gas?
leaded gas has lead in it, unleaded does not Leaded petrol (or gas as you Americans quaintly call it) contained a chemical called Lead Tetraethyl to improve its performance. It was then discovered that the amount of lead given out by cars (or automobiles) was making city air dangerous to breathe and so its use has been forbidden. All petrol/gas is now unleaded and "green". Car engines have needed to be redesigned to allow them to burn the unleaded fuel.
