what do you guys think? better than no lube at all right? or bad idea?
Sorry if this comes across wrong, but chain lube is a fiver, why would you even consider using anything else??
No, no and furthermore, no. Art will be along in a moment to provide the facts 
Well no, because it would be no lube at all… :crying:
Depends if it is WD40 new chain lube.
WD40 isn’t a lubricant. so no, it isn’t a good idea and is the same as no lubricant. go buy some chain lube.
blurb.
450ml. Cleans, protects, displaces moisture, lubricates rusted and frozen parts, removes dirt and grease, dissolves adhesives, dries electrical systems and more.
from the back of the can you could surmise that it would be good for cleaning your chain, or at a push helping to refurb’ a neglected rusty one, but as a lubricant in its own right? NO!
If you’re pushed for anything to use because you can’t get to a shop, engine oil.
WD40 Make chain lube. 
WD40 as lube?
I can think of several things that would be worse- Doritos, sausages, Scarlett Johansson.
Scarlett Johansson works fine as a lube for me…:blink::w00t::w00t::blink:
I thought you’d be more interested in the sausage. 
Fact is I despair…
WD40 in the (blue and yellow can) Water Dispersant formulae 40. Great for dispersing water, spray it all over anywhere where you don’t want water ingress or, where you want protection from water, including wiring harnesses and wiring connectors. DON’T go anywhere near the brake disks, brake pads or brake shoes with it, or with any other lubricants for that matter.
For drive chain lubrication clean off with paraffin and a soft brush and leave to dry. Lubricate with either fresh engine oil (because there’s always enough left over from an engine oil change) or an SAE 80 or 90 gear oil, wiping off any excess oil with an oily rag. Another alternative to oil is a specialist chain wax, I tend to alternate between oil and wax.
DON’T use WD40
DON’T use old engine oil
**** sake not this again :laugh:
Ideally keep it off the wiring. WD40’s not great for plastics, and unless it’s particularly warm and/or thin leaves a residue behind that eventually gums up.
It’s better than nothing. Lots of people seem to approach chain lubing as if their chain doesn’t spend a huge proportion of its time covered in filthy oil anyway. What you put on this afternoon is what’s there for the next couple of hours’ riding, and beyond that it’s anyone’s guess.
Sure, it’s best to use $favourite_lube, but old engine oil’s hugely better than nothing, and much better than lots of other things that one might consider.
I have been thinking of using KY gel
It is a lube

Well that solves it :hehe:
my bad!
I always assumed that something like this would be better than nothing for the chain… as in, generically providing a bit of lubrication.
lesson learned!
thanks guys.
and btw: not everyone has the skills/the time/the tools to take the chain, de-install it, clean it, oil it, and put it back on (without messing something up). And this is the reason why I always relied on sprays that you can put on the chain with a standing bike.
I do of course understand that in a perfect world everyone does it the proper way… Bottom Line: I’ll find a good chain lube to spray on there instead of WD40
thanks Guys!!
frankstan, don’t remove the chain to clean it!!
this process should take you 10 minutes, 15 if you don’t have a centre stand.
small amount of paraffin in a jug, a toothbrush. dip toothbrush in parrafin, and clean chain with it, grime slides off double quick. once all gone over, wipe off the gunk with a rag. leave for a few mins for the last of the paraffin to evaporate and apply you chain lube of choice, never lube a dirty chain.
simples. not a single part removed. no need to!!!
sheesh, if you had to remove the chain, it would never be done, by any of us, except Art and NumNum perhaps.
The general problem with using WD-40 and other penetrating lubes (GT-85, AC-90 etc.) is that they function as penetrating lubes partly by breaking down other oils (especially those that have gummed up and jammed something). So while they’d each be better than nothing on a completely unlubricated chain (in that they’d provide some lubrication very briefly), they’ll be worse than that on one with any lube at all, since they’ll remove the extant lube and then sod-off themselves.
I’m not convinced by the idea that a clean with the sort of solvents that most people recommend is particularly worthwhile. Unless I’m misunderstanding all these seals the gumpf on the boxes go on about it seems that you’re likely to remove lube from places you’ll not be able to replace it, and it’s best to just use a relatively light lube and keep replacing it.
I have a chain cleaning tool a bit like this
http://www.demon-tweeks.co.uk/motorcycle/chain-tools/bike-it-chain-cleaning-kit
it’s basically a box with a bunch of brushes in it that clips over the chain and has tubes to let you run your choice of cleaner fluid though the brushes and be collected in a container.
The cleanest and easiest way to clean a chain that I’ve found: clip it on, turn the wheel to spin the chain and occasionally squeeze a bit of fluid through, a few rotations later it’s clean and after a bit of a wipe the cleaner evaporates ready for a spray of lube.
