Fuel additive attracting rodents?

[DMW]

2 years ago I started using Star Tron as a fuel stabilizer for winter storage.All of the sudden the rubber fuel lines and plastic gas caps were being chewed up by either mice or squirrels. Log splitter, pressure washer, zero turn all required new lines this year, 2 plastic gas caps had both been chewed, 1 required replacement. Never an problem like this in 30 years. Changing the additive was the only difference I can think of. They were stored in 2 different buildings, a hundred feet apart.
Anyone else have anything similar happen?

I've heard that more and more plastics have soybean derivatives in them, and rodents find it attractive.

Rodents hit my diesel fuel return line (low pressure, still lost a couple gallons before I realized what was going on - tractor now gets parked in a container), and they chew on just about any plastic in our car engine compartments - none of these have a fuel stabilizer.

I will note that I had rodents hit the whole house vacuum lines in my house - but they only attacked the joints, not the main pipe itself. Something interesting in the glue?
