It's absolutely critical to apply proper oil to the chain after applying WD40. If not, it will start squeaking again after riding a short time, and running the chain dry will cause extreme wear to the pins. In a pinch, automotive oil can be mixed with kerosene or a small amount of paint thinner and poured on the chain. Non-thinned oil won't work! Also, if you use paint thinner, be sure to let most of it evaporate before using the chain since it's a fire hazard. Also, if the chain has been run dry for a very long time, it's probably too worn to be usable - check the wear and replace if necessary. If you do, be sure to lube the new chain properly - the thin machine oil on new chains is only to prevent rust, not lubricate!
