I have a Nauta bladder fuel tank. It is made of nitrile neoprene rubber.
I am worried about the E10 fuel I have been running in it dissolving the tank.
Your high ethanol fuel problems in the US haven't made it to Europe yet, so there is likely a very limited number of people here who could say with certainty from an even smaller number of people who have such a tank. The manufacturer should know - but it will depend on the material the bag is made from, the adhesives used to hold it all together and any fittings etc.
A list for selecting rubber gloves suggests that neoprene has very good resistance to Ethyl Alcohol, so I would guess that you're probably OK.
A check with the manufacturer would be wise though.
If anyone from Brazil is on here, perhaps they could comment on incompatible materials for use with ethanol (they're reportedly using E85 there pretty routinely)?
Round where we do our boating alot of is E10. If filling at a normal car petrol station we usually have to plump for the 98RON stuff, nowadays usually excillium or ultimate or some other brand name. On the water there is usually only 98 available anyway.

Over here, 95e will totally disappear 01.01.2011 and will be replaced with E10. On water guess the 98 will be the main fuel, at least for owners of Yam 2ST engines anyway....
