Hate to say this JJ, but there are negatives to E10.....in exactly the areas
that you have stated
E10 absorbs water, so metal fuel tanks will rust....
It also is corrosive to aluminium, so the TVA on Smarts is definitely going to be
a 'target'...in fact anything aluminium that E10 fuel comes into contact with WILL
breakdown/corrode if not in regualr use. There are even some rubber/plastic
fuel lines that will breakdown and corrode.
So...this is yet another example of inept and uninformed beaucrats passing
a Bill etc without consultation or understanding or investigation into the
outcome or affects of any such changes being forced upon the voting masses.
Or maybe they are/were aware, because if you think about it, it is about the
fastest way to forcibly make everyone buy into electric cars !
Oh, and if ANY cars are left unused for any substantial period of time with E10
fuel in them, then the most sensible thing to do will be to drain the fuel tank
and all the fuel lines, and flush them through...but with what I cannot say
as I'm not up to speed on what will flush E10 out and leave zero residue.
PLUS...you can bet your ass that it will not be something easy to do for the
vast majority of people, that is for sure.
