octane, alcohol, petrol, toluene plus the smell of oil rags and of doing donuts...
NSW'S E10 unleaded fuel mandate is a ''debacle'' and is costing the state's motorists millions, according to an international study.
The Texas Tech University research found motorists had a ''significant aversion'' to the ethanol blended product.
With the push for E10 reducing the availability of regular grade unleaded, motorists had instead flocked to the more expensive premium petrol because of concerns about E10's potential engine damage as well as fuel efficiency.
Most modern engines are constructed to take ethanol in the combustible mix. In my book, ethanol is a dry combustible that is too say it has no lubricating property. None. When used in model aeroplanes 2-stroke engines, ethanol has to be mixed with oil for lubrication and petrol. Pure ethanol burns with far more efficiency and far hotter than petrol.
Under high compression, any sort of oil will burn and explode. In big ships, heavy oils, that would even clog up diesel engines, are used. Most diesel engines can cope with banana oil or french fries oil should they be the only ones available... But in the end it's a question of maximising efficiency and retail management.
One is trying to "save" the environment by using E10, when one actually is doing a service to the sugar cane industry — an industry that is subsidised to make ethanol. Wine does not have ethanol but methanol, which is a different alcohol that has no permanent side effects, except when "abused". Ethanol is made from methanol by a separate chemical process, but ethanol is basically deadly for consumption. It will induce blindness and kill quickly should it be ingested.
As the articles in the picture above point out, the octane rating is one of the most important for engine power. In small aviation, the fuel (petrol) is usually 100 octane (pure petrol — no solvents), though I know that at times some pilots had to call on the 98 octane petrol at power stations when the 100 octane fuel is not available. It demands a different setting for the fuel/air mix (which always needs to be adjusted as altitude varies — the higher the plane, the "thinner" the air is).
As one can see from the advert by shell on the right in the picture, they advertise methyl benzene as a power boost for your engine. Methyl benzene (benzine) is TOLUENE (a solvent). Toluene is used to manufacture paints and other stuff but it burns rather well and in the process of refining naphtha, toluene may settle at the same level as petrol in the "cracking" towers. Though it also can be added to. Most petrol at the pump contains some small proportion of toluene — except in the 100 octane.
The petrol companies may as well sell you the toluene as an engine booster which they do, or simply as a filler part of the lower quality "regular" (91 octane)... One of the draw back is that toluene is classified as an "aromatic substance" and as blended in the petrol is the source of "petrol sniffing" acting like powerful drugs with dire consequences. This is why in most Aboriginal communities, petrol is the low aromatic kind or the 100 octane to minimise sniffing.
When filling up your car at petrol stations, avoid breathing the fumes. It's not the petrol that can damage your brains but the "extra aromatic substances" that will.
