Does a 1991 laser uses unleaded or leaded fuel?

A 1991 Laser uses unleaded fuel. Unleaded fuel is a type of gasoline that does not contain lead, a toxic metal that was once commonly added to gasoline to increase its octane rating. Lead is harmful to human health and the environment, and has been phased out of use in most countries. Unleaded fuel is now the standard type of gasoline used in vehicles.
