Good question.

I wonder what "lube" is left after the WD40 solvent has evaporated?
Could it be just bog standard oil?

Would it not be better to recommend the following to spray the chain?

No I think it is better than that I did a test a while back :-
Two pieces of mild steel were degreased and polished, one was coated in WD40 the other 3 in 1 oil applied. Two egg cups were filled with a strong saline solution and left in all day, at night both pieces were taken out and left to dry to encourage oxidisation.

What is it with people and WD40, the clue is in the name (Water Dispersant, formula 40), WD40 is a water dispersant first and does have some qualities of a penetrating oil - not strictly speaking a lubricant though.

eh?

They say it is a lubricant on their website. It says it is a lubricant on the can. It contains oil. It lubricates.

is there something complicated about that which I missed...? :shock:

I think WD stands for water displacing. I believe the original objective was to formulate a water displacing lubricant and the 40th formula worked best. I used it as chain lube for many years. Quick spray every few days, or after a wet ride, and wipe excess off with a rag, removing surface dirt at the same time. Never cleaned the chain in solvent. Chains lasted 4-5 K miles. I switched to light oil for a while but that seems to collect a lot more dirt, so now use Halfords general purpose bike spray lube in the same way.

While I don't dispute the fact wd40 contains a lubricant I wouldn't use it myself because it is so light and most of it would fling off.

It would be better than nothing though.

I have just bought some WD40 spray chain wax - no results as yet though.

you need to let it dry (overnight preferably) before you ride the bike.
