Dex-cool jugs are tough?
Willwrens post about Dex-cool and gaskets made me remember this.
Last year when I was cleaning up the garage I found three Havoline Dex-cool jugs sitting on concrete behind a large box. One jug was marked empty the other had an inch or two of used Dex the other jug had over a quart of unused Dex and was marked New. I took the small amount of used Dex and pored it down a rat hole on the edge of the property and put the jug back with the others.
Last month I needed gallon jugs to recycle the green antifreeze in my 75 Chevy truck. I picked up the two empty jugs and for some reason rinsed them out with the hosepipe. The jug marked empty rinsed out fine but the bottom blew of the jug that used to have old used Dex in it. So I go and check out the jug with the unused but old Dex in it and it is still solid.
Now I wonder what would have happened if I had rinsed out that jug a year ago?
