My CRX runs E85 but it's been sitting for the winter under a car cover, I wanted to start it up this weekend, lube up the engine and roll the tires a little, but I understand E85 waters up really fast.

How fast? Does cold make it worse? Should I flush the gas tank anyway? etc.

 

Well ive read that E50 has a shelf life of 85-100 days, so id assume E85 is the same.

I also read that the E85 could last years and years if i was sealed, if its open to the atmosphere they say it could become a little diluted

 

i think the trick would be too keep the gas tank completely topped off because if there is room inside it would be easier for condensation to build up? i know this is usually true with large diesel trucks
