I oil mine regularly, on the trip. and then put a new one on when I park it at home
to be ready for the next trip.
older 5~8 speed chains are what I ran*, as I never adopted the 9+ speed drivetrains , ..
Now I adopted an IGH bike , and get to use even wider chains.
full bushing 1/8" chains are really long wearing.
*Typically Sedisport chains.
