How To Test Ethanol Content In Gasoline

How do you test for the presence of ethanol? Add 1ml of 1% iodine solution to it. Add dilute sodium hydroxide solution drop wise until the brown colour of iodine is discharged. Heat the mixture gently in water bath. The formation of yellow precipitate indicates the presence of either ethanol or acetaldehyde or methyl ketone.

How do I know if my fuel has ethanol? Most gasoline that’s available uses ten percent of ethanol in its mixture, and this variation is known as E10; The number that appears after the “E” tells you the percentage of ethanol by volume within the fuel. Any type of fuel that goes over ten percent ethanol by volume will have a label on it such as E15 or E85.

What is a high ethanol level?

The presence of ethanol in blood at concentrations above 30 mg/dL (>0.03% or g/dL) is generally accepted as a strong indicator of the use of an alcohol-containing beverage. Blood ethanol levels above 50 mg/dL (>0.05%) are frequently associated with a state of increased euphoria.

What does 10 percent ethanol mean?

Ethanol is an oxygenate, meaning it adds valuable oxygen to the gasoline. More oxygen in a fuel allows it to burn more completely and cleanly. Ethanol is 35 percent oxygen by weight, so a 10 percent ethanol blend produces gasoline with 3.5 percent oxygen.

So, if you have exactly half a tank of 87-octane gas and half a tank of 93-octane gas, then you’ve just got a full tank of 90-octane gas. Adding higher octane gas to an engine designed to use lower octane gas will never be a problem.

Does removing ethanol from gasoline lower octane?

This phase separation of the gasoline/ethanol mix lowers the octane number and may cause knocking in an engine, while the engine will not run at all on the ethanol/water layer.
