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.

How do you tell difference between leaded and unleaded petrol in a can?
I don't think there is a way to visually tell the difference between leaded and unleaded fuel. However, leaded gasoline has become "extinct" and it is more likely that you have unleaded gasoline in the can.
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.
What is the difference between leaded and unleaded fuel type?
Leaded fuel which has been banned for sale in the U.S. has a lead additive added during the refinery process.
What is the different between leaded and unleaded fuel?
leaded fuel contains lead which damages the engine while unleaded fuel contains negligible amount of lead.... on older engines the lead in the gasoline was to lubricate the valve stems in newer cars they have designed that requirement out
what is the more economic fuel leaded or unleaded?
leaded fuel is economic compared to unleaded because more distance is covered with leaded than unleaded
Did 2 liter pinto engines run on leaded petrol?
No, the 2-liter Pinto engines were not designed to run on leaded petrol. These engines, produced in the 1970s and 1980s, were generally designed to operate on unleaded fuel, aligning with the automotive industry's shift towards unleaded petrol during that time. Using leaded petrol could potentially damage the engine's catalytic converters, which were increasingly being used in vehicles to reduce emissions.
Does a 81 Corvette take leaded or unleaded?
unleaded
Will unleaded fuel damage a leaded motor?
Unleaded fuel generally won't damage a leaded motor, as most leaded engines are designed to run on a variety of fuels. However, if the engine has been specifically tuned for leaded fuel, using unleaded might result in slightly different performance characteristics, such as reduced lubrication for certain components that benefited from lead. Additionally, older engines may require adjustments or additives to ensure optimal performance and prevent valve seat wear. Always consult a mechanic or the manufacturer for specific guidance.
Does a 1991 laser uses unleaded or leaded fuel?
Unleaded
What are substitutes of leaded petrol?
unleaded
1984 Chevrolet Corvette leaded or unleaded fuel?
unleaded fuel
What is Specific gravity unleaded petrol verses leaded?
Specific gravity is a measure of the density of a substance compared to the density of water. Unleaded petrol typically has a specific gravity ranging from about 0.71 to 0.77, while leaded petrol generally has a slightly higher specific gravity, around 0.72 to 0.83. The difference in specific gravity is primarily due to the different additives and chemical compositions used in unleaded and leaded fuels. Overall, unleaded petrol is designed to be more environmentally friendly and efficient, reflecting a shift away from leaded fuels.
