What are you most concerned about as a family of cars?
Does the car look good? Is the road blocked? Or is the price of oil expensive?
We all know that car oil in Australia is divided into the following types
#91 Unleaded Petrol (ULP)
Most commonly used unleaded gasoline
#95 Premium Unleaded Petrol (PULP)
High-quality unleaded gasoline, usually every oil company will give their home 95, 98 has a specific special name, such as Caltex's Vortex,BP Ultimate
#98 98 RON （Research Octane Number） (RON) of 98
High octane number unleaded gasoline, that is, high number gasoline, the higher the octane number, the stronger the explosion resistance of gasoline, and the better it is to the car.
Disel
Diesel, usually used in designated vehicles
Do you know? There's also a very special kind of gasoline in Australia.
E10
According to official Queensland government data, E10 is a mixture of up to 10 percent ethanol and 90 percent unleaded gasoline. Premium E10 is a similar mixture of ethanol and advanced unleaded fuel.
Over the past 10 years, carmakers have improved engine technology, and today more engines are built on E10 fuel.

So, combined with the official statement,
E10 gasoline is a very green and energy-saving "green" automobile fuel.
But!
Many motorists are being forced to use E-10 gasoline, despite growing scepticism about cost savings and environmental benefits. Other states except New and Queensland have so far been using ethanol-mandatory temptation in boycott, but federal government is considering phasing out or upgrading ordinary unleaded gasoline.
"compared with ordinary unleaded gasoline, drivers who use the E10 do not save more because it has a lower energy density," said vehicle exhaust experts.
"in other words, you need to burn more E10 to drive the same distance as a regular lead-free car."
The latest figures show that many motorists have been forced to buy the higher-priced E-10 unleaded gasoline. The promotion of E10 gasoline was originally intended to make it cheaper, but if you look at the long-term average, it is not cheaper than ordinary unleaded gasoline. The E10 also has an unexpected effect, prompting motorists to buy high-quality fuel. This means they have to pay a higher price every time they fill up with oil.
Emissions experts say the E10 is not economical unless it is at least four cents / litre cheaper than ordinary unleaded gasoline. But long-term average prices show that the price difference between the two is usually 2 cents per litre.
Kunzhou's government requires the E10 to account for 30% of unleaded gasoline sales at gas stations. Next month, the state will raise that to 40%. The E10 accounted for just 2.4 percent of unleaded gasoline sales outside New and Kunzhou, according to the Ministry of Environment and Energy. In Kunzhou, E10 accounted for 17 percent of all unleaded gasoline sold in the first four months of the year-just over half the current 30 percent target but less than half of the 40 percent target that will be enforced in July.
Considering the ecological effects of raw materials, fertilizers, agricultural machinery and production processes, the overall environmental benefits of E10 are variable. From oil wells to wheels, the environmental benefits of ethanol blends have yet to be determined. Its environmental impact is likely to be worse than the use of regular lead-free fuels, depending on its mode of production, "energy experts said.
As part of a review of fuel quality in Australia, the Federal government is considering whether ordinary unleaded gasoline should be further refined to meet modern international standards. Gasoline lobbyists say Australians can use cleaner fuel, but the cost of fuel will be higher. Car companies say they can't run their efficient engines if they use Australia's "dirty" gasoline, which is among the world's top 50.
Ordinary unleaded gasoline in Australia is currently allowed to contain less than 150ppm, while the highest standard in the rest of the world is 10 ppm. In the debate, ethanol-blended gasoline continues to be touted as an alternative fuel. However, independent tests have repeatedly proved that the E-10 does not have the same mileage as the average unleaded gasoline. On highways, the E10 is 4% less energy efficient, while in cities and suburbs, cars using E10 consume 7% more fuel than those using regular unleaded gasoline.
See here editor can not help but ask: not everyone runs the highway every day OK!
Then why are we spending more money on the more expensive E10?
