+1 on this, though it is really a cleaner. I use Parker Hale Express oil as a strict 'oil', Parker Hale Youngs 303 inside the bores and Parker Hale Rangoon oil for preserving external surfaces ...... and no, I don't work for Parker Hale!

I also strongly agree with the post about cleaning away the dirt and grit before re-oiling - probably more important than the oil itself.
