Bob,

Do not let you get scared by the industry. They just want to sell additives.
There are very few people who have had problems with fuel, be it E5 or 
E10. If they had, it was mainly because of deteriorating old rubber 
hoses, diaphragms that should have been replaced years ago anyway and/or 
rust/dirt in the tank that dissolved once they started using the car 
again. When a car is well maintained and in regular use, there are 
hardly ever problems if at all.
I have found the same having had petrol in a can for years in the boot 
as a reserve. When I finally needed it there were no problems at all.
The fuel we have today is different from that in the '60s, but is does 
not mean the quality is worse.
