For a light oil I use a good qaulity airline oil like silkolene
currently, contains various additives for rust prevention, anti
oxidants, anti foam etc, can even be used in hydraulic systems.

I sympathise regarding the qaulity of the container, it has annoyed me
for years that grease and some other products seem to come in hard
plastic containers that dropped once split, gaffer tape to the rescue.

The entire red top came off, not the small cap. This isn't the first time.

Their oil can "looking" plastic containers are utter **** as well. They
leak when you don't want them to, and when you need oil, basically nothing
comes out.

The garbage packaging is why I will no longer but this stuff.

so, who still sells oil in metal cans these days, even it has to be mail
ordered?
