View Full Version : Simple test for Ethanol

I just done a test for Ethanol in petrol using the glass bottle and water method.
You should try it and be horrified.

I had a small bottle with no taper.
Added some water and made a mark on the outside.
Added some unleaded to almost fill the bottle and made another mark.
Gave it a good shake, the water separates immediately and returns to the same level.
It left all of this sit for two weeks, no change.
All of this is very good news.

I have just repeated the test with E10.
Straight away a very milky layer formed between water and petrol.
After a shake the water level has risen, I would say that 5% of the E10 has turned into water.
Also, the water takes a lot longer to separate after being shaken.
The sample will be left to sit for say two weeks and the test repeated.

I am horrified that this rubbish is being sold at all.
It just goes to show how much hold the sugar cane growers and the petrol companies have over our so-called government.
All sample fuel came from a high-turnover Shell petrol station.

You should all do the test and give yourself a good fright.
If you have any doubts about your fuel supply do this test whenever you fill up.

Nah I would say that 5 % of the alcohol or ethanol has mixed in with the water!

So now you have high octane water! but the petrol has a lower octane now.

Pretty sh!t stuff Huh.

if you do it with 100mls of petrol it makes it very easy to work out the %age just remeasure the level afterwards and that gives you reading, problem is we are finding more like 20% when we test but we only wait 10 min

Good info I had a diesel motor rebuilt and poor fuel caused it to run like a dog until new fuel was purchased
