Yes most likely it will If it is equipped with a catalytic converter. I doubt it is that high tech. If it isn't, don't worry. It might say unleaded, but that is because it doesn't need lead, and also because unleaded is the standard these days. All gasoline engines can run on leaded, unless a catalytic converter is installed.
Unleaded, most vehicles manufactured post 1983, particularly Japanese are made to run on Unleaded
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.
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.
Leaded fule has real lead in it, because the valves or piston rings needed this extra lead for lubrication. Usually it is older cars that use leaded fuels, such as cars made before 1996. Any vehicle equipped with a catalytic converter cannot use leaded fuel.
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.
Your engine says to use leaded gas in it because when it was made, leaded gas was what you got. The lead was there to protect the valves in a four-stroke engine. A two-stroke like yours has no valves, so it needs no lead. Ipso facto, so long as you keep putting a good grade of two-stroke oil in your gas, you can run all the unleaded in it you want.

At first glance, it doesn't make any sense at all.But when you look at it overall, it makes perfect sense.Engine development and gasoline development go hand-in-hand: if you can't get good fuel that doesn't cause knock when it's burned, you can't make powerful engines. Knock tears engines apart.The people who make engines figured out how to make engines that require gas with high resistance to knock faster than the people who make gas figured out how to make that fuel. Enter a man named Thomas Midgley, who learned how to make lead soluble in gasoline. This "tetraethyl lead" (so called because there are four ethyl groups surrounding each lead atom) came packaged with lead scavengers to keep the lead from accumulating in the engine, and when added to fuel it made the antiknock index go up faster, and cheaper, than it would have by just using petroleum distillates. Gasoline that's SUPPOSED to have lead in it is about 60 octane before they put the lead in it.Later, the oil refiners learned to make high-quality chemicals from oil. They could have used these chemicals to make unleaded gas that won't tear your engine apart, but there's more profit in specialty chemicals than in gasoline.So...the answer to your question is, "unleaded gas contains more costly ingredients than leaded gas did, so it needs to be more expensive."AnswerWhen leaded gas was first introduced, you were getting something extra that cost more to produce, so leaded gas cost more. When the government started requiring non-leaded fuel almost all fuel being produced contained lead. The regulations were so strict that if leaded gasoline had ever been in a tank no unleaded gas could be stored in that tank. So, in order to produce unleaded gas the whole refining, transportation, and delivery system had to be duplicated. Another answer is: unleaded was something Americans introduced along with catalytic converters in the 1970's. Europeans and the rest of the world's countries didn't use any other standard gasoline than leaded until mid-1980. It was still standard well up in to the 90's. USA banned leaded gasoline in 1986. In Europe unleaded was unusual. Most cars could run on unleaded, but it was recommended use leaded to get higher octance rating and less engine wear. Some people cared for the environment themselves and used unleaded or even bought a car with a catalytic converter. Therefore the demand for leaded, which was standard everywhere, but in USA, was still high.Not all European stations had unleaded until mid or late 1990. Some European governments increased taxes on leaded gasoline and later made catalytic converters a requirement for new cars to enforce unleaded use of gasoline. In the late 1990's, most European service stations had added potassium as a lead-substitute, but this is also being phased out.

Unleaded petrol is what you have before you add the tetra-ethyl lead (or similar antiknock compound) to the base fuel. The TEL allows a cheaper and lower octane fuel mix to be made. Petrol is combination of various hydrocarbon distillates from very small molecules like butane to very long chained molecules. These are mixed to provide proper combustion in an engine. The rating for this quality is known as the octane number. Leaded compounds, if added, boost the octane rating. ----------------------------------- Leaded petrol is now banned in many countries. The tetra-ethyl lead is extremely toxic and cause pollution. Unleaded petrol may contain methanol, ethanol, MTBE, ETBE, etc.

The most common use of leaded glass is in decorative items. Items such as bowls and figurines are often made from lead crystal. Leaded glass is also used within stained glass patterns.
