Dave in Oz writes about Ethanol fuel..
I have enjoyed reading your site for many years. I finally got hold of my own listeroid and have been playing with that setting it up.
Many people don’t understand my concern with self sufficiency but I sleep well at night knowing if the lights go out I can put them back on again.
I also have run my Vehicles on WVO for 8 years now and the only problem I had was when I ran low recently and my wife put Diesel in my 4WD. It was obviously rubbish fuel and was blocking filters every day. Annoying when you Run your vehicle on rubbish and have no trouble and then you PAY for ” proper” fuel and it turns out to be the real Rubbish!
Flushed that out, back to the WVO and not a problem Since.
Anyway, I read of your love for Ethanol and that you are getting E15 in the states. I have had the same experience as you with Ethanol Fuel ( I’m in Sydney Australia) It basically buggers everything it goes in.
I have had trouble with mowers and chain saws, It stuffed up the Fuel system on my Harley and gives lousy fuel economy that is no where near offset by the lower price in vehicles.
One of the reasons I went from petrol to Diesel Vehicles.
I blend 5-10% in my WVO for easier starting in winter and to restore the timing of ignition. The ethanol however vaporizing about 20 oC lower than regular petrol gave me problems with vaporisation. I couldn’t understand how so little could cause the problems I was seeing until a friend rightfully pointed out a Liquid going to a gas expands roughly 1000 Times. That meant that 1ML of ethanol was giving me a litre of air in the system.
Made sense why I was having trouble.
Obviously I wanted the ethanol out. I could distill it but I came up with an easier way.
Wash it out.
I get say 20L of E 10 as we have here, throw in say 5L of water and give it a shake. Water and eth goes to the bottom and good, clean pure Petrol to the top.
Takes only a few minutes to separate but I usually leave for an hour or overnight for good measure.
I decant the petrol, not to carefully as I add the dregs to the next batch and repeat.
Water and Petrol DON’t Mix but water and Ethanol love one another.
Nice, easy way to get pure petrol.
The water/ Eth doesn’t go to waste either. I have water injection on my WVO powered vehicles ( a washer bottle with a garden misting nozzle spraying into the intake , $20 all up) and this adds power and keeps the engines Free of any Build-up and dirt from the intake manifold to the exhaust and everything in between.
Since using the washed Fuel I don’t find the lawn mower need water draining out of the carb every time I use it, The other garden equipment starts and runs as it should as well and I just don’t have the problems I was having and never had before the soft of heart and heads made this etha crap mandatory.
The vaporisation problems in my truck when mixing it with WVO disappeared on the first tank full and it was hot weather when I tried it and would not have been surprised if regular non blended fuel Vaporised anyway but not a hint.
You might like to try this George and see how you go. Just get a coke bottle with some E-rubbish, add some water, shake, settle and give the properly refined Petrol a go.
I’m looking to buy a small Cone bottomed plastic tank to make the separation phase easier as I only use petrol in small engines but you can get those tanks in any size so if one wanted to do 50 Gal at a time you could get a suitable sized tank.
May not be worth it for vehicles but for small engines where you want the fuel to last, I think this works real well.
Have Fun George and thanks for a great site.
Dave always good to hear from a Cousin down under.. lots of self reliant DIYer types down your way..
As for the Ethanol fuel, I agree washing out ethanol is easy and works well if you are looking to mix gasoline and WVO together as a fuel..
As for the use in gasoline engines, this may be ok in extremely low compression engines on old equipment, but we may need an octane booster after we strip the Ethanol away. My understanding is one of the few advantages of ethanol is it does raise the octane of the mix a bit.. so removing it means you likely have a lower octane Petrol fuel, and may see destructive pre detonation. WE need beware of how we might improve the octane (if necessary) with after market additives as it might contain more alcohol.
As for the savings with ethanol, they (our governments) rob us from one pocket to make the stuff.. and then charge us more for stuff that gives us less mileage.
One thing we know, Australia and the USA have both have elected officials that like to live well on the public purse.
