last time i had my degas bottle out, i overfilled it upon reinstalling, and it caused the cap to leak. i didnt know about the new level until reading it on here. opened the hood and saw coolant trails, flipped out thinking it was headgaskets, only to learn i had overfilled the bottle. talk about sweet relief. i keep my, like stated, about a 1/4" below min. it will fluctuate between the minimum mark and 1/4" below, depending on engine temp. this is normal. zero "puking" now.
