Diesel fuel does not have lead added, but it is not the same as unleaded gasoline.Diesel fuel does not have lead added, but it is not the same as unleaded gasoline.
It will do damage to a diesel engine. Drain the tank and flush the fuel lines. Do not run this engine with unleaded gasoline in the tank.
All gasoline ever produced starts out as unleaded. Lead was once added later after refining to control pre-ignition and detonation. There is no way to remove lead from gasoline that already has lead in it.
Unleaded gasoline is regular gasoline. Lead used to be added to gasoline to prevent engine knocking but the practice has been banned in most developed countries. 2nd Answer: There are some engines, a lot of them not in cars, that are made to use regular gasoline. They are designed so that the lead in regular old gasoline will build up on certain moving parts, and keep them sealed against engine pressures. Unleaded gas is not good for this type of engine, at all.
There is no risk in mixing super unleaded gas and regular unleaded gas. Super is just given to the name of a gasoline because of cleaning agents and octane added to the gas not because the gas is completely different.
Actually, the first gasoline was unleaded. Sometime in the 1940s lead was added to increase the octane rating. Environmental legislation in 1975 began the phase-out of leaded gasoline.
It depends what you mean by 'better'. Lead used to be added to gasoline to stop pre-ignition or detonation (which causes engine knock or 'pinking') but it was found to have very bad side effects environmentally and physiologically. most countries have banned the use of leaded gasolines, and modern gasoline have other ways of dealing with detonation. so i guess, unless you like bad air and bad health, unleaded is best.
Catalytic cracking breaks down larger organic molecules in petroleum into smaller pieces. It doesn't in itself produce "leaded" gasoline, though lead antiknock compounds (or other additives) may be added afterward.
it is added to prevent freezing of gasoline
Leaded gas started being phased out in the late 60's. Catatytic converters, which can only burn unleaded gas, were made mandatory in 1975, so that pretty much ended the production of leaded gas.
It will not run or if it is mixed with gasoline it will not run correctly and smoke depending on how much diesel was added.
It gets VERY expensive! Check out "DUI - A Costly Mistake" in the related link I added.
