Why do so many people use WD-40 as a lube? Im not being a smart *ss, from what I understand WD-40 is an abrasive, but why do so many people spray it on things like chains to lube them?

It's also bitchin for removing sticker residue.

I've never heard of it being an abrasive, I don't think it would be too good on clear plastics though, and I heard it's best to avoid painted surfaces with it as well (like for de-icing door locks in the winter).

Gm use something simular called MP50 and its a mosture displacement lube. GM also has Heat Valve Lubricant. its ammonia based and will eat the rust out a the Titanic. its good stuff if you ever want to try it just go to the dealer and get some.

oh, all most forgot. theres this stuff called "iron Clad" its a lithium based spray for preping engine blocks & cranks for storage. kind looks like snot but it won't wash off sitting in the garage.

WD is short for water displacement. The number 40 represents that this was the 40th formula that they tried before they got one that worked. Thus WD-40. It is advertised as a lubricant basically as a marketing ploy. How many people are in the market for a water displacement spray vs. looking for a lube or rust penetrant. It will do these other things, but is far from what it was designed to do. PB Blaster or Seafoam Deep Creep are much better as rust penetrants.

Yea im a bike tech and everyone thinks wd-40 is chain lube or good for it... Its terrible it eats away grease and definatly does not lube stuff at all... Everything has its own special style of grease or lube... hell if it didn't oil would fill the tranny engine and diffs. Then there are things that are good for lots like lithium grease... try flow is a good light lube too. and im a fan of pb for those stubburn bolts

WD stand for water displacment . the 40 was his 40th attempt to make what is in the can .

WD-40 does serve as a lube for applications that will not see high preasure . its thin and will dissplace easily under preasure .

Spraying chains and so on is to dissplace moisture , not for lubrication purposes .:gman:
