The mixture known as gasoline, when used in high compression internal combustion engines, has a tendency to ignite early (pre-ignition or detonation) causing a damaging "engine knocking" (also called "pinging" or "pinking") noise. Early research into this effect was led by A.H. Gibson and Harry Ricardo in England and Thomas Midgley and Thomas Boyd in the United States. The discovery that lead additives modified this behavior led to the widespread adoption of the practice in the 1920s and therefore more powerful higher compression engines. The most popular additive was tetra-ethyl lead. However, with the discovery of the environmental and health damage caused by the lead, and the incompatibility of lead with catalytic converters found on virtually all US automobiles since 1975, this practice began to wane in the 1980s. Most countries are phasing out leaded fuel; different additives have replaced the lead compounds. The most popular additives include aromatic hydrocarbons, ethers and alcohol (usually ethanol or methanol). In the U.S., where lead was blended with gasoline (primarily to boost octane levels) since the early 1920s, standards to phase out leaded gasoline were first implemented in 1973. In 1995, leaded fuel accounted for only 0.6 % of total gasoline sales and less than 2,000 tons of lead per year. From January 1, 1996, the Clean Air Act banned the sale of leaded fuel for use in on-road vehicles. Possession and use of leaded gasoline in a regular on-road vehicle now carries a maximum $10,000 fine in the United States. However, fuel containing lead may continue to be sold for off-road uses, including aircraft, racing cars, farm equipment, and marine engines until 2008. The ban on leaded gasoline led to thousands of tons of lead not being released in the air by automobiles. Similar bans in other countries have resulted in lowering levels of lead in people's bloodstreams.[8] [9] A side effect of the lead additives was protection of the valve seats from erosion. Many classic cars' engines have needed modification to use lead-free fuels since leaded fuels became unavailable. However, "Lead substitute" products are also produced and can sometimes be found at auto parts stores. Gasoline, as delivered at the pump, also contains additives to reduce internal engine carbon buildups, improve combustion, and to allow easier starting in cold climates. In some parts of South America, Asia, Europe and the Middle East, leaded gasoline is still in use. Leaded gasoline was phased out in sub-Saharan Africa with effect from 1 January, 2006. A growing number of countries have drawn up plans to ban leaded gasoline in the near future.
Regular unleaded gasoline.Regular unleaded gasoline.
The best gas mileage from unleaded gasoline or premium gasoline depends on the car. Old cars get better mileage from unleaded.
It takes unleaded I think
Yes, it is unleaded. No gasoline sold for consumer vehicles in leaded.
Yes you can use premium gasoline in unleaded because premium gasoline is also unleaded. The only reason it is called premium gasoline is because it has a higher octance then regular unleaded. Regular unleaded has an octane rating of 87 and premium has an octane rating of 92. Premium gasoline burns slower then regualr gas because it has a higher octane rating.
gasoline that has not been treated with a lead compound
Petrol is the French word for gasoline. Petrol is usually unleaded gasoline. Canadian gas stations advertise gasoline as Petrol, as do many other countries.
Premium gasoline is unleaded. Yes, you can use it, although there may be no actual benefit in it.
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.
The advantages of using premium unleaded gasoline compared to regular unleaded gasoline is its increased efficiency and higher burn rate. It is designed to work in higher combustion engines and will often produce poor performance in vehicles designed for regular gas.

All the 1996 Fords call for unleaded gasoline ( varying octane levels depending on the application )
