When Was Leaded Petrol Banned In Australia?

Due to the dangerous nature of its major constituent, lead, leaded petrol was phased out of Australia on January 1, 2002. Leaded gasoline was a major contributor to high levels of pollution in major cities, according to the Department of the Environment and Energy. 1

Lead has been related to birth difficulties, intellectual impairment in children, and lead poisoning, hence it has an impact on the general public’s health.

Lead has been connected to birth problems, children’s intellectual disability, and lead poisoning, so it has an impact on the general population’s health.


When did leaded gasoline become illegal to buy?

When health concerns about lead became apparent in the 1970s, unleaded gasoline was introduced. Leaded gasoline for use in on-road cars was totally phased out in the United States on January 1, 1996. Leaded gasoline is no longer used in most other countries’ cars. Gasoline is now commonly sold in three grades at retail stores.

Is it possible for ancient cars to run on unleaded gasoline?

Modern unleaded variations don’t operate well with cars designed for lead-based fuels. Lead is required to protect compounds in fuel valves, and without it, aging engines will suffer significant damage and wear. Not only that, but ignition firing can be influenced by current fuels and may need to be reset and altered to function with them.

Pure petrol with a high octane rating is practically extinct in the UK, with only a few providers still selling it at the pumps. Because old automobiles aren’t constructed for current alternatives, which can be far too abrasive in the fuel system, they rely on this type of fuel.

Since the restriction on older-style lead-based gasoline in 2000, fuel businesses have offered normal unleaded combined with a tiny amount of ethanol. Ethanol is added to gasoline to make it more environmentally friendly, but because of its corrosive qualities, it isn’t suitable for older vehicles that weren’t designed to run on it.

Fuel companies have produced new fuels with a higher percentage of ethanol as the government attempts to crack down on petrol and diesel cars. This means that historic car owners will have an even harder time finding a fuel with a low enough ethanol content to use in their vehicles.

Ethanol-based fuels are detrimental for classic cars for a variety of reasons, including:

  • Ethanol is hygroscopic, which means it absorbs water. Moisture can condense in the fuel tank and cause rusting of components, especially if the car is stored for an extended period of time.
  • Ethanol-based fuels provide 30 percent less power than older types of gasoline, so performance of older cars not designed to run on this type of fuel may suffer.
  • Ethanol is a powerful solvent and can corrode materials like rubber and fibreglass, both of which are often found on classics.

Is it possible to use unleaded petrol in older vehicles?

Is Unleaded Gas Harmful to Old Vehicles? Most classic-car owners have no issues with unleaded petrol, but it can be a concern if the vehicle is used frequently, such as when towing a trailer or driving a muscle car. If you suspect a problem, fuel additives might be utilized to protect engines.

In which countries is leaded gasoline still used?

Tetraethyl lead (TEL) is an organometallic chemical that is added to gasoline to raise the octane rating and act as an engine antiknock. Tetraethyl lead has been in use since the 1920s, however it has now been found to be poisonous and is no longer used in most parts of the world. The Earth Summit of 2002 campaigned for a worldwide ban on leaded gasoline. Leaded gasoline was planned to be phased out globally by 2006. The health risks of lead and its damaging effect on the environment are the grounds for the ban on leaded gasoline. Although the majority of countries have adopted the ban, several continue use leaded gasoline. Algeria, Iraq, Yemen, Myanmar, North Korea, and Afghanistan are the countries in question. The conversion from leaded to unleaded petrol has financial implications, which may be the main reason why these countries have been unable to make the switch.

What is the best gasoline for vintage automobiles?

In my classic car, what type of gasoline should I use? Customers frequently inquire about the best gasoline for their historic vehicle. We wanted to share this knowledge with other classic automobile aficionados because the answer is lengthier than the question.

Many older gasoline engines have been designed to run on high-octane leaded gasoline. Fortunately, this fuel is no longer available (for environmental and public health concerns). As a result, classic car owners should consider other options. In this article, we’ll look at the most prevalent gasolines: Euro 95, Super 98, and E10. We also discuss the usage of lead substitutes, high-octane gasoline, and LPG driving.

Euro 95 or Super 98?

Engines with higher compression, on average, require higher octane fuel than engines with lower compression. The lower the octane percentage, the less likely it is to ping or detonate. Pinging is the spontaneous igniting of an air-fuel mixture after the ignition time has passed. In the combustion chamber, this causes opposing forces, resulting in an uneven path and a hammering or beating sound. It may be obvious that this is bad for the engine; it can cause major engine damage.

The decision between Euro 95 and Super 98 is still up for debate. Many classic British automobiles will operate on 95 if the ignition is properly set. In general, with E95, this should be a little later so that no spontaneous combustion happens (too close to the top dead center). Euro 95 is ideal for engines with a lower compression ratio, especially those with a lower compression ratio. This covers sedans, as well as sports vehicles with a lower compression ratio that were delivered to the American market in the 1970s (MGB, TR6). The highest potential octane content will benefit the sportier driver the most. With 98, tuned engines with quicker camshafts perform better and last longer.

E10 gasoline (ethanol)

Ordinary Euro 95 is more than enough for many classic automobiles. It’s crucial, however, to make sure there’s not too much ethanol in the mix. E10 gasoline (which contains 10% ethanol) is, for example, completely unacceptable. Many soft parts in the gasoline system are damaged, including rubber hoses, diaphragms in the fuel pump or carburettor, cork, and zinc. In addition, old gasoline residue can dissolve in E10, resulting in pollutant concentrations elsewhere. Ethanol (a kind of alcohol) is also attracted to water. This can result in moisture and, as a result, corrosion in the tank, especially if the tank is stored for an extended period of time. Euro 95, for example, frequently contains 5% ethanol. If your classic hasn’t been driven in a while, it’s a good idea to refuel it using premium gasoline with the lowest possible alcohol level (Super 98, V-Power, Excellium, etc.).

(In our website, you can get a variety of fuel system wear parts for Triumph and MG sports cars.)

Some providers offer E10 additives that are specifically designed to mitigate the negative effects on our classics. We don’t have any experience with these products, therefore we can’t comment on their long-term effects.

Lead substitute

If the cylinder head has not yet been rebuilt to unleaded specifications, adding a lead substitute makes sense. Softer valve seats are protected by the lead substitute. They will wear faster without the additive, resulting in compression and power loss. We sell a Castrol lead alternative in our online store.

High octane petrol

In Germany, certain gas stations sell 102 grade gasoline. This grade is sold in the Netherlands under the name Competition 102 by Firestone. Although the benefits will be difficult to perceive in most cars, it is comforting to know that this high-octane gasoline contains no ethanol.


Personally, I think gas is fantastic for cooking, but I would never use it in a vehicle. Typically, our classics are not driven enough to compensate for the higher costs of installation and maintenance. Furthermore, I’m an originality freak who despises drilling holes where they don’t belong. Respect your vehicle by removing the LPG installation.

Always store with a full tank

This keeps the inside of the tank free of humidity and rust. Is the vehicle in storage for an extended period of time? Keep in mind that after around 6 months, the average Euro 95 gasoline becomes obsolete. In that situation, it is preferable to refuel with premium gasoline. Always inspect the petrol hoses under the car and in the engine compartment after extended storage, and replace the fuel filter on a regular basis.

What type of gasoline is used in lawn mowers?

Unleaded gasoline with an octane value of at least 87 is the finest choice for your lawnmower (91 RON). Importantly, the ethanol percentage of the gasoline cannot exceed 10%. (E10 petrol). If the fuel contains too much ethanol, it will attract water, which will settle to the bottom of the tank, allowing germs to grow and corroding your lawn mower. Your lawn mower should not run on E15 gasoline.

Because it contains only 5% ethanol, most people use “Super Unleaded 97 or 98 RON gas in their lawn mower. In tiny engines like your lawn mower, premium fuels (such as Shell V-Power) offer minimal benefit.

Can you use E10 petrol in a lawn mower?

Although E10 gas will operate your lawn mower, it is not the greatest sort of fuel to use. Because ethanol attracts water and can cause corrosion and engine damage over time, you should use fuel with as little ethanol as possible. You can use E10 petrol on occasion, but if it’s available where you live, 98 RON Super Unleaded is a preferable option.

E5 fuel (which contains 5% ethanol) is healthier for your engine in the long term than E10, especially if you have an older lawn mower. The older your mower, especially those manufactured before 2010 or so, the poorer it will function using E10 fuel.

Also, avoid leaving E10 fuel in your gasoline tank for long periods of time, as it can thicken with time.

Is it possible to blend old and fresh gasoline?

For a multitude of reasons, old and fresh gas should not be mixed, the most important of which are:

  • Because the old gas degrades with time and has already lost its combustibility, it should not be introduced.
  • It has the potential to cause sputtering.
  • It’s possible that it won’t start.
  • It may prevent the engine from performing to the driver’s expectations.
  • It has the potential to create knocking.
  • Injectors might become clogged as a result of this.

All drivers who have inefficiently blended old and new gas in the past have experienced one or more of the concerns listed above. Fortunately, none of these problems are unavoidable; they may be effectively avoided if one understands how to securely blend old and new gas.

The gas that should not be mixed can simply be judged by its appearance and smell

Only gas that hasn’t lost its combustibility can be blended with fresh gas in a tiny amount to start the engine. As a result, determining whether or not the gas is usable is critical.

The stored gas would have a deeper hue and a strong, odd, and sour odor that should never be mixed with fresh gas. Even in little amounts, the gas that appears foggy and murky in particular situations should not be mixed with new gas.

Is premium petrol better for older cars?

It will not improve the performance, speed, mileage, or cleanliness of your vehicle. Detergent additives in gasoline are significantly more important than octane level since they assist clean your engine and improve performance. Each retailer has a unique mix of additives that are used in all grades.
