I LOVE SEATTLE, I used to live just north of you in Victoria (on vanisle). Yes, apparently cheap gear lube you just apply with a sponge or a brush after cleaning your chain and sprockets is the best if you feel like maintaining your chain.
At least, from my recollection, Vancouver Ryan/YouTube master said in one of his videos.
That's where I disagree. (And that is based on long experience).
Cheap gear lube just adds to the blooddy mess, both on the chain and on your bike.
In the 'Old Days' (pre O-ring)... grab a pie tin, add grease, lay the chain in and bake it in the oven.
Then you would incur the wrath of your GF/spouse/mother.
Grease would last for a few miles. Chain life... maybe a couple thousand unless you took it off road,
then the life expectancy was even less. Some of the bikes (Bultacos, small Hondas etc) had fully enclosed chains,
the life expectancy of chains was pretty good in those, those enclosures kept the grit away !
