E10 Petrol

[cyberstorm]

In Denmark / Europe from this year you can get some petrol called E10 it should be more environmentally friendly but is it something we can use in our petrol tank to run on without destroying the engine ?

This is what I read recently..........

It is believed that the higher bioethanol content in E10 petrol could dislodge deposits in older engines and fuel systems, causing blockages; it could also cause some seals, gaskets, metals and plastics to corrode.

Perhaps it may be worth waiting a while until issues are ironed out?

ok thanks, so it is best to keep away from E10 and use what you normaly use

I've used E10, when in Europe, on occassion, but always switch back to E5, as soon as possible.

I certainly wouldn't use it in a vehicle that didn't cover many miles, where a tank of fuel might sit for long periods.
Ethanol is hygroscopic, which means it attracts water, which is not what you want in an engine, or a steel fuel tank.

To be honest I think the true answer is that no-one knows how new liquids / additives will work over time - for example, I can remember when STP fuel treatment came out, people used to say that it could dislodge deposits in older engines and fuel systems, yet everyone swears by it now.   I think the easy answer is to just service (clean) your tank / injectors etc. as often as you feel you need to and you should not have too many problems. If you really want to go down the way to help 'save the planet' then forget using cleaner fuels - just sell your machine and get a pedal cycle - but wouldn't that be a little boring! 
In a few years anyway we will all be riding electric bikes which I am told are 100% environmentally friendly - not sure how they are gonna generate the electricity to charge the bikes though or to power the machines that will be manufacturing them if that is the case!

The owner's handbook says fuel with ethanol in is ok as long as its no more than 10%

There is also a bit about trying a different brand if you are not satisfied with the drivability when using fuel with oxygenating alcohol additives.

I read that as it may not work as well as proper fuel but shouldn't do any harm.

ok what page number in the handbook is it on ?
