If it's a real old engine ( 1979 or older ) they do because the valve seats are soft
not harden,and todays fuel will take the valve seats out of the heads. If you are going to use old heads with todays gas they will have to have hardened seats put
in the heads.
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
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.
leaded fuel is economic compared to unleaded because more distance is covered with leaded than unleaded
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.

Leaded gasoline can cause significant damage to engines by forming deposits on spark plugs and valves, leading to misfiring and reduced performance. The lead compounds can also corrode engine components, resulting in increased wear and tear. Additionally, leaded gasoline can foul the fuel system and catalytic converters, ultimately leading to costly repairs and decreased fuel efficiency. Overall, the use of leaded gasoline can significantly shorten an engine's lifespan and impair its functionality.
Immediately serious damage will be done. Why in the world would you want to use leaded fuel which you cannot even buy in the U.S. Where are you getting leaded fuel and why?
unleaded fuel
Why would you do this? This is difficult to do by accident as the filler nozzle, through which unleaded fuel is delivered, and the filler pipe on the car are both narrow. The wider nozzle used with leaded fuel and diesel just will not fit. Leaded fuel will quickly destroy the catalytic converter and O2 sensors. What other damage will be done is hard to say. Use unleaded and forget leaded fuel.
Leaded fuel which has been banned for sale in the U.S. has a lead additive added during the refinery process.
in the UK, leaded fuel was banned in the year 2000, it was replaced for a limited time by LRP(lead replacement petrol) but nowhere in the UK has any of these pumps in their stations anymore. Other countries would have banned leaded fuel a different times
Unleaded fuel should always be used in a modern engine. Leaded fuel causes a detrimental buildup that will quickly destroy your bike.
