The constant use of Stabil will help forestall problems. Further, keep the tank full anytime the car is stored to minimize condensation.

Perfect written.
We've had it for a decade in Sweden 5% during the winter.
A lot of people are converting to E85 since it's classified as enviromental friendly.
Eats and detoriates rubber, fuel lines.
The fuel pump plastics in my 1966 fuel pump embritteled.
Disolves a lot of old "gue"
No stories from here that CIS are more sensitive.
About rust I think they add inhibitors in Sweden.
But now new fuel lines and so on are resistant to Ethanol.
If its a CIS it must be a couple of years so it might be time to change fuellines clean gastank and so on anyway.
btw bio diesel contamination in regular diesel is a growing problem.
