I read a post by some individual who has put something like 200k on his VFR, and it was directed to a question posed by someone asking how many chains he went through and what his regimen was. In essence, his response was something like "Each chain I tried different levels of attention, from never cleaning it to oiling it regularly every 250 miles or so, and all my chains have lasted about 20k miles." So, use what you like and keep the rubber side down. I use Dupont chain lube.
