LPG. LPG fuel, also known as liquid petroleum gas, is a clean-burning alternative fuel made from natural gas or petroleum.
Otherwise known as Ultra-Premium by some brands, 98 is the highest-octane fuel currently available in Australia. Unleaded 98 provides higher engine power and overall performance in comparison to 91 and 95. It is also responsible for less pollution, according to providers.
Do I get the same fuel economy out of E10 as regular unleaded petrol? At the pump, E10 is generally the cheapest petrol per litre. Because the energy provided by the ethanol is less than the energy provided by pure petroleum, E10 has around 3% less energy than the equivalent amount of RON 91 petrol.
According to NRMA motoring expert Jack Haley, on average 95 RON can give around 4 per cent lower fuel consumption than 91, assuming the engine computer adjusts to take advantage of the octane difference.
So, if your car requires 91 octane then you can use that, or if you're happy to pay a little more for enhanced performance, you can use 95 petrol. The advantage of higher octane fuel is a greater stability under pressure – it is less likely to combust in the chamber before it's supposed to do so.
It is okay to mix fuels (except for diesel) in your car as long as the octane rating is not less than the recommended fuel you should use. For example, if you have a car that takes 91, then mixing with 95 is fine, but not the other way round. A car that takes 95, can only mix with fuels that are higher like 98.
Even if your car is cleared to run on the new E10 fuel, you may choose to run it on super-unleaded anyway. Super-unleaded should prove slightly more economical, so you'll be able to get more miles out of a tank of fuel, and some are said to clean and maintain the internals of your engine.
It is believed that the higher bioethanol content in E10 petrol could dislodge deposits in older engines and fuel systems, causing blockages; it could also cause some seals, gaskets, metals and plastics to corrode.
98RON UPULP generally costs up to 50c per-litre more than E10 so it can be an expensive way to fill your car for very little performance gain, although there are benefits with no ethanol content meaning it is safe to use in all petrol cars, and can help protect the engine on very hot days when there is a risk of poor ...
Unleaded 95
This is primarily used by more high-performance cars, but it can also be used by most vehicles on the road. The main difference between unleaded 91 and 95 is that the premium unleaded fuel can resist pinging longer which is better for the engine.
Ampol Bio E10 Unleaded Petrol is a high-quality unleaded petrol formulated with up to 10% ethanol. It meets the requirements of the Fuel Quality Standards Act 2000. Ethanol is a renewable non-fossil fuel which helps reduce greenhouse gas emissions and reliance on fossil fuels.
The answer is simple: they just have very loyal customers. To purchase their gas, you have to be a member, and membership sales make up about 75 percent of the chain's profit.
Diesel Burns Clean
Diesel fuel engines produce about 95 percent less carbon monoxide than a car with a catalytic converter and a car with a catalytic converter release about 84 percent fewer hydrocarbons into the atmosphere and emit 15 percent less carbon dioxide.
Ethanol. Ethanol is a widely used renewable fuel made from corn and other plant materials. It is blended with gasoline for use in vehicles.
Natural gas one of the safest and cleanest fuels available. It emits less pollution than other fossil fuel sources. When natural gas is burned, it produces mostly carbon dioxide and water vapor -- the same substances emitted when humans exhale.
That said, it recommends avoiding prolonged use of E10 petrol in a non-compatible car as this can result in long term harm to the engine. If you do fill up with E10 fuel, don't panic - just remember to fill up with super unleaded or premium fuel next time.
E10 petrol's higher bioethanol content is corrosive to rubber parts, gaskets, seals, metals and plastics, which causes engine damage, so it could dislodge deposits in older engines and fuel systems, causing blockages. It should only be used with expert advice, which means pretty much never.
- Use of ethanol can be the reason for mileage loss. It is because ethanol (E10 fuel) molecule contains less energy value than petrol. This is the reason why have less energy potential, which hampers the mileage. Water content not good for your vehicle!
Most, but not all, modern cars can use E10, so it's important you check first before filling up with E10 fuel. The Federal Chamber of Automotive Industries says some E10 unleaded petrol blends are marketed as 94 RON. That means they do not meet the fuel standards for cars recommended to use 95 or 98 premium fuels.
If your vehicle is compatible with E10 petrol, there's no reason you can't mix the 2 grades of petrol (E5 97+ and E10 95+). It's perfectly safe to mix them in the same tank or fill up with E5 if E10 is not available.
E5 petrol corresponds to the fuels SP95-E5 and SP98-E5. E5 means that the petrol contains up to 5% bioethanol, blended with unleaded 95 or 98. E10 petrol, or SP95-E10, is unleaded 95 enriched with 10% bioethanol.
Premium unleaded is both 95 and 98. The ethanol-blended e10 (a mixture of up to 10% ethanol in petrol) is a fuel that can be used as a substitute for 91 in most cars. Those numbers – 91, 95 and 98 – encompass the octane rating of the fuel. They're all about the same in terms of the energy in the fuel.
Engine Protection
98 petrol, which is more stable and resistant to 'knocking', is a better choice when it comes to engine protection. 95 petrol works as well, but if your engine is powerful, it will use higher pressures that 95 petrol may not be able to withstand.
Mixing the grades to get 91 or so shouldn't hurt, but it probably isn't saving you much money. Using anything higher than your manual recommends probably won't help your car's performance – but using lower might save you a few bucks, Leroux says. If you notice knocking, you should switch back.
