Cue an increase in garage fires and people with no eyebrows.  (someone must have a better fire smiley)

Not sure 10 gallons of petrol going up would leave you with just singed eyebrows.
I think Charles Darwin had a theory  that could be applied here.

You could always ...

UK Diesel is already up to 7% Bio ....

 

[Wittsend]

Yes, but it's a different "bio"

does this have a impact on older, 200tdi, rubber parts

[Wittsend]

No

Thinking about my 6 year old mower sent them the serial number and asked (if OT sorry) -

Dear Sir/Madam,

 

Thank you for contacting us at STIHL Customer Service. This message is in response to your request for information on the compatibility of STIHL engines with the new fuel composition in the UK.

Naturally, we understand the uncertainties and concerns that this change raises in our customers. E10 petrol will contain up to 10% renewable ethanol. This is intended to help reduce CO2 emissions, but we know that some of you may have concerns about how this will affect your petrol tools. We recommend in all of our owners’ manuals that you should only use high-quality brand-name petrol with a minimum octane rating of 90, but we can reassure you that petrol with an ethanol content of 10% or less, like the new E10 petrol will not cause a problem with your STIHL petrol tool.
 
However, petrol with an ethanol content of more than 10% can cause running problems in engines with a manually adjustable carburettor, so should not be used in such engines.
 
In some tools, it may also be necessary to readjust the carburettor to compensate for the changed composition of the fuel. We recommend that you visit a STIHL Approved Dealer for this.
 
However, if you still want to use standard petrol, we are happy to reassure you that the new E10 petrol is fine to use in your STIHL petrol tools.

Finally, we include a couple of links with relevant information in this regard:

We hope that the information provided has been useful to you. For any other questions, do not hesitate to contact us again.

Kind regards,

No

....but the more "Bio" diesel in the mix, the more your vehicle will smell like a chip-shop :-)

Thinking about my 6 year old mower sent them the serial number and asked (if OT sorry) -

Well I have a Stihl brushcutter, less than 5 years old, and E5 turned the rubber fuel pickup tube into chewing gum and destroyed the carb. After I let the pickup pipe dry out, it went hard and brittle. The Stihl agent  (Four Crosses) was unable to repair the carb, and put it down to the fuel  New carb and pickup pipe and run it on Esso Super (no ethanol) since and no further probs, but I empty it of fuel after finishing using it. I think a lot of contract gardeners would disagree with Stihl's response. Maybe I should have claimed off them for the repair!

Problem is the Esso Super stuff in our area now has ethanol

There's some confusion here regarding "Bio Diesel".

People are using the term "Bio Diesel" for 2 different fuels.

1) The more common usage if for using used chip shop oil.
Some people process this at home, others just bung it straight in. Some mix it 50:50 with pump diesel.
If you collect waste chip oil you area s likely as not to get a waste carriers license from your local council.
Another process is to methylate the veggie oil - this makes it for all intents and purposes the same as dino diesel.

2) The second fuel called "Bio Diesel" is what the oil refineries use and blend in with dino diesel.
This is labelled B7 which means it may contain up to 7% of FAMEs - fatty acid methyl esters produced by methylating virgin veggie oil.

Be aware - there is B10 around and B20 is coming round the corner.
For this the refineries use veggie oil harvested from the fields - maize, corn oil. The oil can be converted to ethanol - see the previous posts ^^^ or methylated.
Either way you are taking away food stock 
These bio diesel fuels are good BUT they have low sulphur content and that's bad for engine lubricity. So they add an additive package at the refinery to the diesel.
You can buy your own additives which also improve the cetane rating - as discussed above ^^^

There is no ethanol in bio diesel and diesel users will not experience the troubles the older petrol vehicles have.

Using premium pump diesel is not really needed - but in running the odd tank through you will notice the extra oomph due to the increase in cetane rating. Again, you have to balance the cost of premium fuel against the extra mpg gained.

 
Please note: It's not a good idea to run the CAV DPA fuel pumps on waste or virgin veggie oil 
Even if you blend it with pump diesel. The CAV pumps can't take it and will soon seize up, they are metered for a different viscosity of fuel 
The Bosch injector pumps love the stuff !

Of course there's always the one exception to the rule, who will claim they've been running on waste oil for years with no problems

Of course in an emergency, such as being pursued by Customs & Excise in your ancient petrol lorry laden with contraband whisky, a higher alcohol content can work well enough.  :)

According to the UK Govt most (96%) of the "Bio" bit in "pump" diesel is actually processed waste cooking oil rather than "new", so for that at least, its not true to say its taking away from food production ?

[Wittsend]

That's as maybe - I was thinking on a more global scale where in the states giant ethanol plants have been build at the expenses of using corn as a base stock for flour, dextrose sugars and cooking oil.

True for diesel, however only 9% of bioethanol ( for petrol )comes from waste products.

Every time you switch on the TV you are bombarded by fundraising adverts for starving people  . Still, I am sure what little food they are getting is probably being delivered in  shiny new eco friendly vehicles.

(sorry, my mother once said I was a "cynical ba*****" at the age of seven).

Sorry to continue a bit more OT but just spotted this on Stihl's blog on E10
Of course, if you are concerned about the use of ethanol in your machines, then you can always consider our premium, patented fuel formula, MotoMix. STIHL MotoMix is completely free from ethanol and has virtually no olefins or aromatic compounds. Emission-wise, this makes it a cleaner, more environmentally-friendly choice than regular fuels, plus it lasts longer so you can store it for up to 5 years, which is handy as MotoMix is available in 200 litre drums!

So even though they say E10 will be fine in their 2 stroke engines, they are selling stuff with no ethanol in it, which apparently is also even more environmentally friendly (than what??)

£20 to £30 for 5 litres
