I don't recommend vial spikes, especially not with something that you're probably going to use for months. Transfer to smaller vials instead. There's a thread whereby we soaked spikes and syringes into low solvent oils and none of the shit can handle it. None of them were designed to handle it. Even if it looks fine, nobody really knows what's leeching.
We got some action already. It looks like the satilite dish part is starting to laminate off with these strings. I know it is not a part of the internals or what actually touches the oil but worth noting. A few fell right off after I agetated it this morning:
Now, you can see here, that type of plastic is starting to "corrode" (cloudy parts) or break down. It looks like sun damage on an old vehicle when it sits in the sun for too long:
You can see the whole inside of the spike up into the housing looks degraded:
Big difference...
