How to Test for the Ethanol in Petrol

TO USE

Pull out the plunger on the trimmed syringe to the 50ml mark and then using the untrimmed syringe draw up your sample from either your tank or can. Now fill up the the trimmed syringe to the zero mark

Here is a simple test kit I have developed to test the amount of ethanol in a sample of petrol. With  increasing amounts being added to fuel and its detrimental effects on older cars. I came up with this kit so you can actually see how much ethanol you have in your tanks I will post up some further information on the effects of ethenol on our cars later but for now, here is how the kit works.

Here is the kit, pretty simple really, just two 60ml syringes, with one having the end trimmed down. I used these firstly because a have a cheap sourse and secondly they are easily portable and fit the neck of a standard petrol can

add petrol add water

Now pull the plunger back further to the 60ml mark and fill to the zero with ordinary tap water, put your thumb over the open end and give it a shake

Now allow the sample a few minutes to settle, the water will go to the bottom the petrol will rise to the top. In the middle you will get the  ethanol which will have reacted with the water and turned a cloudy slightly yellow colour. Its hard to see in this picture but there is definitely a cloudy area between the water and the petrol one segment thick on the scale. If you now double this reading you get a 2% ethanol reading in this sample

When testing the largest percentage I have found so far is 14% from a local ASDA (this sample was taken from my local Morrisons)
