Pure ethanol – 100% ethanol or E100 – could theoretically be used to power cars, but generally isn't, for numerous reasons: Ethanol is bad for cold-starting, because it doesn't burn as quickly as gasoline. (It has a higher octane, if you're interested.) Pure ethanol would be useless as fuel in the winter months.
Ethanol: Contains significantly less energy per gallon than gasoline. Is hygroscopic, meaning it absorbs water out of the air, which means it can damage engines due to excess water content if not handled carefully.
Flexible fuel vehicles (FFVs) have an internal combustion engine and are capable of operating on gasoline and any blend of gasoline and ethanol up to 83%. FFVs have one fuel system, and most components are the same as those found in a conventional gasoline-only car.
One of the biggest threats to the long-term performance of a 2 cycle engine is ethanol, which is blended into most fuels. Many 2 cycle products are on the edge of not being able to function with anything over E10 (10% ethanol, 90% gas), and E15 fuels (15% ethanol, 85% gas) are becoming more common.
Ethanol is Corrosive
Ethanol reacts naturally with oxygen in the air to form acidic compounds which lead to corrosion of fuel system components and engine wear.
Ethanol can damage many parts of your car at concentrations above 10%. Ethanol can destroy gas tanks, fuel pumps, gaskets, and attract moisture into your fuel. Engines can be completely ruined over time if they're not designed for ethanol.
The disadvantages of ethanol and other biofuels include the use of farmland for industrial corn and soy growth, rather than for food crops. Also, biofuels aren't meant for all vehicles, especially older vehicles. There is some resistance from the automotive industry when it comes to adding biofuels to the market.

Due to similar combustion characteristics, ethanol can be used in petrol engines. While some engines use petrol blended with a small percentage of ethanol, others are ethanol-only. There are several advantages of adding ethanol to petrol. Reduction in emissions is one of the key advantages of using ethanol.
Ethanol is known to be an acceptable fuel for gasoline engines because it has a high octane number [13]. Pure ethanol cannot be used in diesel engines, but it can be used by in blends with diesel fuel.
Re: adding methylated spirits to petrol
So they put in additives to make it taste revolting, and print POISON on the bottle, but its ethanol, and absolutely fine for you petrol tank.
The alcohols become more like petroleum fuels as their chemical weights increase. Methyl alcohol has the lowest combustion energy of all the fuels listed. However, it also has the lowest stoichiometric or chemically correct air-fuel ratio. Therefore, an engine burning methyl alcohol would produce the most power.
Ethanol can be extremely damaging to small engines and high-powered sports equipment, leading to corrosion of the engine and fuel system.
Every now and then, though, I get this: Vodka like all other alcoholic drinks is hydroscopic so if you put some in your (gas) petrol tank then it will get into the fuel system and make the engine misfire or stop running altogether. don't do it.
One explanation is that gasoline smells less due to dilution with ethanol. Though some (incorrectly) claimed that this was a government conspiracy to raise gas prices, it is actually true that gasoline can contain added ethanol, at about 10 percent.
ED95. ED95 designates a blend of 95% ethanol and 5% ignition improver; it is used in modified diesel engines where high compression is used to ignite the fuel, as opposed to the operation of gasoline engines, where spark plugs are used.
If your car is E10 compatible you can choose bp Unleaded 91 with up to 10% renewable ethanol when you fill up at a station offering this grade.
The Cabinet Committee on Economic Affairs (CCEA), headed by Prime Minister Narendra Modi raised the price of ethanol extracted from sugarcane juice to Rs 65.60 per litre from Rs 63.45 per litre for the supply year beginning in December 2022.
Putting diesel in a gas car can clog your fuel filters and fuel injectors, making your vehicle suddenly inoperable. This is because diesel fuel is thicker than regular gas, which causes it to gum up your car's internal systems quickly.
Diesel engines with vegetable oils offer acceptable engine performance and emissions for short-term operation. Long-term operation results in operational and durability problems. Straight vegetable oil is not the same as biodiesel and is generally not recommended for long-term vehicle use.
The Government suggests that putting E10 petrol in a non-compatible car on a one-time basis should not result in your car's engine being damaged as a result. 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.
Higher-ethanol blends still produce significant levels of air pollution, reduce fuel efficiency, jack up corn and other food prices, and have been treated with skepticism by some car manufacturers for the damage they do to engines. Growing corn to run our cars was a bad idea 10 years ago.
Ethanol has a higher octane number than gasoline, providing premium blending properties. Minimum octane number requirements for gasoline prevent engine knocking and ensure drivability. Lower-octane gasoline is blended with 10% ethanol to attain the standard 87 octane.
It's better for the environment because it's a sustainable energy source, is clean-burning, and the small amount of odorless CO² it produces – the same CO² that's in the air we breathe – is reabsorbed by plants. Unlike wood and gas, when ethanol burns it doesn't produce any smoke, soot, ash or unpleasant odors.
