Edit: For context of the below rant you need to see the many user documents on the WD-40 deal - https://www.ozbargain.com.au/node/921148
I started using this a few months ago, far better than my tainted memories of the non lubricant WD-40 in it's penetrating/loosening aspect, plus it does actual lubricate.
wouldn't rate it quite as good as the Wurth Rostoff range, but pretty close. For the price difference, it makes Wurth hard to swallow unless you have some crazy stuck thing that you can't use heat on.
As per the recent WD-40 post, in my time as a professional bicycle mechanic, I tested WD-40 by spraying a fully stripped cleaned bike chain until it was soaking wet. A few hours later we tested it and found it to be 100% dry. The following day we fitted it to a bike and it squealed like a pig from being so dry.
For those that feel they have had WD last longer, I am assuming you already had some lube/factory grease still on the chain. WD would have broken that down, and if not removed 100% of it, it would still be present and active.
Last night I sprayed a corrugated iron wall, and another peace of clean steel and a fully cleaned motorcycle chain, that has been sitting dry in my shed for over a year with Shift Ya Bastard. Tonight I felt all three items and they were all showing signs of a wet lube.
That said, don't use this or WD as a bicycle chain lube, just go buy a proper bloody bicycle chain lube, even half assed ones don't cost much and will last aeons. But this will get you out of trouble if you need, and last significantly longer than WD-40.
Anyway, form the Nulon site:

Decent price. Will grab a can..cheers.
WD is just a kerosene based product. Not a lubricant (other than some oil residue from the kero).
