You hear this a lot and it is factually not correct. See below. They also do make a penetrating oil (fluid) that works pretty damned well IMO.

A Question of Lubrication
Myth: WD-40Ž Multi-Use Product is not really a lubricant.

Fact: While the “W-D” in WD-40Ž stands for Water Displacement, WD-40Ž Multi-Use Product is a unique, special blend of lubricants. The product’s formulation also contains anti-corrosion agents and ingredients for penetration, water displacement and soil removal.

What's Stoddard Solvent?
Myth: WD-40Ž contains Stoddard Solvent.

Fact: Over the past few decades, the name Stoddard Solvent was synonymous with all mineral spirits. Today, the mineral spirits found in products like ours are more refined and processed (see hydrogenation, hydrotreating and distillation techniques) providing mixtures with varying boiling points, cleaning ability, and chemical composition.
The catchall phrase “Stoddard Solvent” is no longer adequate to tell the proper story. WD-40Ž does indeed have 50% mineral spirits, but they are refined and purified for specific characteristics needed to meet today’s performance, regulatory and safety requirements.

Bike Friendly
Myth: WD-40Ž Multi-Use Product should not be used on bike chains.

Fact: While WD-40Ž Multi-Use Product it is not a grease, it is formulated with strong lubricating oils and other ingredients, and is a terrific product to use for bike maintenance. It does not attract dirt or moisture to metal surfaces – just be sure to wipe off any excess WD-40Ž Multi-Use Product before riding.

Who's Behind it All?
Myth: Ken East is WD-40Ž’s original founder.

Fact: While Ken East is often referred to as one of WD-40Ž ’s original founders, he used to say, “Heck, I ain’t that old.” Ken was the facility manager at WD-40 Company’s San Diego headquarters and was affectionately known as “The Brewmaster.” He mixed up batches of our secret sauce for over 15 years and was often heard to proudly proclaim, “I absolutely LOVE my job!” Ken happily retired in 2009.
As mentioned in our corporate and brand history, Norm Larsen, founder of Rocket Chemical Company, is considered the original founder of WD-40Ž. Read the real story behind WD-40Ž.

What a Fish story!
Myth: WD-40Ž contains fish oil.

Fact: Consumers have told us over the years that they have caught some of the biggest fish ever after protecting their fish hooks and lures with WD-40Ž. We believe this legend came from folks assuming that the product must contain fish oil since it appears to attract fish. Sorry CharlieŽ, it just ain’t so.
WD-40 Company has taken steps to respect and conserve the environment, and encourages its users to do the same. While WD-40Ž can be used to help protect fishing equipment from rust and corrosion, WD-40 Company does not recommend using WD-40Ž to attract fish.

“WD-40Ž Cures Arthritis!” No Way.
Myth: WD-40Ž cures arthritis.

Fact: This popular headline, appearing at least once a year in the tabloids, is completely FALSE. WD-40 Company does not recommend the use of WD-40Ž for medical purposes, and knows no reason why WD-40Ž would be effective for arthritis pain relief. WD-40Ž contains petroleum distillates and should be handled with the same precautions for any product containing this type of material.

Health and Safety
Myth: Typical consumers need to look beyond the label.

Fact: For the general consumer, the product label provides the key safety and usage information derived from our Material Safety Data Sheet and referred to for the general use of our product can be misleading. MSDS information is for the workplace and not primarily intended for the general consumer. For the general consumer, the product label provides the key safety and usage information.

 

if they are on TIGHT, get the "strap" wrench for oil filters, and you can twist them some, and you can beat rearward on that strap wrench with a rubber hammer.


IDK about all the gaskets, i used to replace them, but I got to doing some much stuff after dealer was closed, I just left the OEM stuff in place. figure if the aftermarket exhaust tip lands in a different area than the OEM tip, it's on a new gasket surface, right? the crossover is one to watch, though,

 

Thanks for all the help

After all the build up in my mind i was armed and ready LOL

it came off a total none issue

Thanks again

Dave

 

 

If you are a believer of WD40 as a penetrating fluid, lubricant, whatever, go ahead and use it. I do not care. And there is a 'penetrating fluid' marketed by WD40, I'm assuming it's a different formula than the original. If the original was so bitchin' as a penetrating fluid, why come up with another product?


I'm not the only one feels like this. There are a LOT of products out there that were developed as a penetrating fluid and/or lubricant that are, and I'm gonna capitalize this so as to be perfectly clear...IN MY OPINION...far better than WD40.


Having said this, I do consider WD40 one of the best choices out there when I want to get rid of water...in old points ignition, nothing else worked better. There have been some threads on this very forum where it was required that water be removed, and the suggestion was made, correctly, to use WD40. It is also said to be good to remove light adhesives, and other things. Great. No issues with that.


My opinion is not based on the World Wide Web...it's based upon personal experiences, and the experiences of folks that have credibility with me, and their opinions. So if you don't agree with me on this, no need to get twitterpated...just continue to use it as you want. Keep it away from me, though.

 

 

Not saying that it doesn't displace water, only that stating it is not a lubricant is factually incorrect. That's all, no problem no upset. If you don't like it, then use what you do like, free world and all.

 

I know this off topic but I saw this a post above...he stated wd-40 could be used to lubricate a motorcycle chain. That may be true on a regular chain but I wouldn't use it on a chain with o- rings or x-rings...the mineral spirits will degrade that material and ruin your nice chain. Back to your regularly scheduled thread

 

Every time i took my exhaust off i used PB Blaster, I sprayed the bolts and nuts and let it sit for about 30 minutes and every thing broke free without breaking off.

 

IIRC, i thought old gunsmiths said WD-40 drew water & made weapons rust? or did i hear that old wives tale wrong?
