Ethanol issues

On a 1980 bike i would also be worried about what this is doing inside the engine.

I'm not mechanically minded, but its my first thought?
 
No, producing corn ethanol does not use more energy than it produces; it has a net positive energy balance. While early studies claimed a negative energy balance, more recent research shows a positive outcome due to increased farming and conversion efficiencies. However, the energy return on investment (EROI) for corn ethanol is low compared to other energy sources and is largely due to the energy credit from the co-product animal feed.

does not sound very positive does it and the farmer is only getting a return as the plant material can be fed to livestock and they will convert it into carbon dioxide and methane!

Suspect it's more of an issue on vehicles that are stored/rarely driven as ethanol is hygroscopic and can also break down (oxidise) over time. If preventative measures aren't taken the resulting water and byproducts can cause corrosion. A vehicle that's regularly used probably isn't going to see many issues.
 
So last year I discovered the rubber fuel hoses on my 1980 V50 had perished. Took the bike to a local mechanic who replaced them all along with a quick oil and filter swap. Last week I dragged the bike out from back of the garage to take her for a little run, turned on the fuel taps, and yup...hoses perished again! I only ever use Shell E5 on my 2 Guzzis, so a bit peed off that they failed again so soon.

Bike is now in Twiggers, Loughborough, who has said he will replace the hoses with a top quality hose? Maybe I should ride the bike a bit more?
make sure he keeps the x over in there.

ps , do you think the Italians follow the law . :D
 
OK apply some kind of energy credit to the equation and it's not quite negative anymore. It's still wasteful and anything but green. Back when our EPA started pushing ethanol to be blended into gasoline almost all engines were carbureted and adding alcohol leaned out the mixture making most run just a bit cleaner. This was no longer the case once fuel injected engines with O2 sensors became the norm.
 
Sorry...took a look at previous invoice...nearer 3 years.
As ethanol was added to fuel from what 2008(?) and manufacturers had been preparing for it for some time before then 3 years is no time at all. Plenty of vehicles running around from before then with no issues at all. Basically it still looks like the wrong type of pipe was used.

Possibly. Was probably standard fuel pipe. Twiggers are fitting a better quality pipe apparently. Probably doesn't help that the bike does around 200 miles a year at the most and usually sits at back of garage doing nothing.

My local garage in Lancashire said the last time I was in that his “ ethanol proof’ hose wasn't and it was his customers who told him! He had to bin the lot!

Also as others have said Esso / BP fuel is all regional. Esso Super in Lancashire was no ethanol , Esso Super in Wales is 5% going upto 10%

Possible. But still a stretch. Id say there is a 90% chance it's not proper fuel hose. Or some really old or cheap shit.

Anyone fitting anything but full ethanol compliment fuel line shouldn't be in business.
 
But what does that have to do with adding ethanol in petrol?

it's part of the equation in reducing CO2 as growing the corn removes CO2 from the atmosphere. The carbon atoms in the ethanol come from the atmosphere not black gloop that has been under the ground for millennia

throughout this thread you seem to be focusing on just the use of ethanol as a fuel not the whole rationale behind the concept of biofuel, whether ethanol or seed oils for diesel. Originally a noble aim but has become completely politicised as I have mentioned earlier in this thread. due to economic interests and polarised ideology.
 
Less CO2 released from mineral oil.
Plants suck up CO2 and the same amount is released through burning it.
Less CO2 less global warming, more stable climate, less or no sea level rise, fewer catastrophic weather conditions.....

But ethanol is bad for bike tanks, fuel lines, your fuel consumption goes up as ethanol is less energy dense compared to mineral oils.
 
We all understand how living plants absorb CO2 and release O2. What I don't understand is how spending all the energy to transport and distill corn to make ethanol makes sense. Why not grow edible plants to consume, trees for wildlife habitat, etc. instead?

which is what I said above, but politics and economics ...
