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.
Regular UNLEADED gasoline, up to 10% ethanol. Does not require high test, not made for E85 fuel.
unleaded gasoline
Where are you at? I haven't seen leaded gas or petrol since I was in grade school. They used to call it "regular" and there was that and diesel until they decided the lead in gasoline was bad for us and started offering unleaded. Eventually, every gas station in the U.S. phased regular gas out. If you have an old car from the days of leaded petrol, you'll probably have to put unleaded in it some time (unless you live in a country where they still have leaded gas at the stations). If you put unleaded gas in an old car, you can get a fuel additive to protect the engine from the harsher fuel. Over time, using unleaded in an old engine can cause some of the gaskets to dry out and start leaking. It won't hurt just one time, but it's an accumulative effect if you do it all the time.

a gasoline engine and a electric moter.
A 1963 Ford Falcon typically uses regular unleaded gasoline. At the time of its production, the vehicle was designed to run on 87 octane fuel, which was standard for most cars of that era. It's advisable to avoid high-octane fuels unless modifications have been made to the engine that require it. Always check the owner's manual for specific recommendations based on the engine type.
An engine that is made to run on E85 differs from a normal gasoline engine in several ways. An engine that is made to run on E85 uses E85 as a biological fuel source whereas a normal gasoline engine that is made to run on normal gasoline runs on or uses gasoline--that is gasoline or natural gas. Both engines' designing mechanisms differ accordingly. For instance, an E85 engine's mechanisms allow it to operate on only ethanol gas but a normal gasoline engine can work on normal gasoline. Notably both engines would look different as their operative mechanisms are designed to operate differently by running on different fuel ingredients and substances. But not necessarily. This may not be likely for an engine's typicality and normality. Engines do look different in many ways but not always; they may also look the same, and in fact they do. In the case of these two engines, the question is not about whether they look different but rather if they work differently. An internal combustion engine--a typical gasoline-based engine--is an example of a normal gasoline engine. It is one of the oldest types of engines used in running motoring machines. Therefore, the many ways in which an engine that is made to run on E85 differs from a normal gasoline engine are functionality, look, design, and capacity in particular. The way in which an engine that is made to run on E85 differs from a normal gasoline engine is in terms of its power source and the way it works or its way of working.
Simply the anser is NO. Only cars that are made to run on E-85 and Regular Unleaded gasoline can do this. E-85 is 85% alcohol, and the fuel delivery system needs to be made to handle this level. Using E-85 in a car not madeto run on it will cause check engine light, codes, drivability problems, poor economy and acceleration, ETC. Tech JK ---------------

The gasoline engine.
The cost of gasoline made their summer plans too expensive. The small engine ran on gasoline mixed with oil.
Since leaded fuel is no longer readily available at most all gas stations, you may have to use an additive. Proper leaded fuel is a little bit better for your engine than non-leaded additives, but hard to get and quite expensive. An additive like Tetraboost adds the lead to unleaded gasoline with lead-scavengers. All vehicles sold in the US from 1971 on are made to run on unleaded gasoline, so there is no need for an additive in your 78 unless you have an older unconverted engine in it. It should run fine on very low octane fuel.
