The Royal Purple spray lube is good stuff

WD40 is handy, but it is terrible at door hinges. WD40 is too thin and quickly allows squeaks to return. I agree with Fife - grease is the best.

WD40 is also not very good with bicycle chains. Once again it is too thin.

Basic rule of lubricants - the faster the part moves, the thinner the lube.

I sometimes use WD40 when I'm drilling steel. I spray it on the bit while I'm drilling.

S'OK Penetrating Oil is some good stuff:

Micro Mist is also great...if you can still find a can since they went out of business. I still have 1.

Also cures ring-worm on livestock

WD-40 is better when cutting Aluminum, not steel.

For steel, use a cutting fluid or cutting oil. I would look into food grade cutting oil. We used (long time ago) standard cutting fluid, but switched to the food grade one. The shop foreman says that it was a bit "better" for you if it smokes/burns.

I found for door hinges that bike chain oil works great. Nice and thick, so it stays in place.

I know there are better oils for drilling steel. But WD-40 is what I have around and I can spray it. Most of the drilling I do in steel is horizontal (a boat dock) so the spray is especially useful.

Gordon notes that it also has other beneficial qualities: His high-mileage 1952 Packard with noisy lifters was in such disrepair that it wasn't worth rebuilding, so he just put a pint of Marvel Mystery Oil in the gas tank and one in the crank case. The car was instantly quieter, smoother and more powerful. He drove it like that for another year.

Will this work? I have a '91 F-150 with the 4.9L straight 6 that has lifter noise. I've taken it to the mechanic who after a thorough inspection says there's nothing mechanically wrong. I've found numerous articles and forums online where 4.9L Ford owners have complained of the same thing but all noted that it didn't affect performance. Can I add a pint of Marvel Mystery Oil to the gas tank and one in the crank case? Will this cause any other issues with my truck?

WD-40 would be horrible for lubricating a bicycle chain, but it can be great for cleaning them.

Zepreserve beats WD-40 any day of the week.

if you don't succeed, try again and again and again and again...

""It took them 40 attempts to get the water displacing formula worked out. But they must have been really good, because the original secret formula for WD-40®—which stands for Water Displacement perfected on the 40th try—is still in use today.""

I prefer Jig-a-loo.

o.k. Does anyone know what WD-40 was origonally used for?

It had something to do with rust/corrosion prevention on ICBMs.

If you are looking for a rust preventor, look for "Boe-shield". It is made by the Boeing company and never evaporates. Leaves a bit of a film, but is used in aircraft to prevent rusting.

They make a few different varieties of it, but they work like a champ. Most of the private pilots I know use it.
