Removing ethanol from petrol

It seems to work judging by the amount of fluid drained after 12 hours.
 
Although we don’t like ethanol, it does boost the octane rating. So does this process leave you with a lower octane petrol ?
 
Kaboom !!!!!

Not going to happen here and I do take risks but not with petrol.

Removing the ethanol also lowers the octane so you need to add something to bring that back up.

What could possibly go wrong ? :oops:
 
'Ethanol is a volatile, flammable, colorless liquid with a slight characteristic odor. It is a psychoactive drug, recreational drug, and the active ingredient in alcoholic drinks '

Looks like a ready market for the blue juice, too....
 
According to the RAC website the current average price for normal" unleaded E10 petrol is is £135.33 / L

If the normal E10 does contain 10% Ethanol and you remove it the you will then be paying £135.33 for 0.9 L

Which works out at £150.37 / L

The RAC website staates that the price of super unleaded which altough marked to meet the legal requirements
of the Govenment, but most suppliers say does not contain Ethanol, is £150.37.

So seems a bit of a waste of time, effort and money to remove the Ethanol and have to add an Octane booster ?


Sadly the exception is for Cornwall and see Esso statement below where super unleaded contains up to 5% Ethanol


Although our (Esso) pumps have E5 labels on them, our Synergy Supreme+ 99 is actually ethanol free (except, due to technical supply
reasons, in Devon, Cornwall, North Wales, North England and Scotland). Legislation requires us to place these E5 labels on pumps
that dispense unleaded petrol with ‘up to 5% ethanol’, including those that contain no ethanol, which is why we display them on
our Synergy Supreme+ 99 pumps. There’s currently no requirement for renewable fuel, like ethanol, to be present in super unleaded
petrol although this could change in the future, in which case we would comply with any new legislation.​

 
You have also gotta ensure whatever octane booster you use, to replace the lost octane on the ethanol, does not contain ethanol too !
 
Mind you, the guy was worried about brass components etc., fair comment.. But, for those of us that have 'E5 proofed' our bikes, just what other horrors does another 5% actually hold???
I get the 'storage' problem, but would have been interested to see that jug left for a week/month to see just how much moisture it would pull from the atmosphere...
Would a simple bit of clingfilm or any airtight seal over the tank filler solve that issue? Or am I missing something? (brain... common sense... )
I just hark back to the 'unleaded' saga, when many expected their valves to disappear through their seats overnight....

Don’t forget this is the modern Commando forum…

I suspect the most difficult thing to ethanol proof on these is the plastic tank…
