Can anyone tell me the downside to using WD40 sprayed on a UNI foam air filter. Larry

As much of a WD-40 fan as I am, I've never considered it thick enough to stay in the filter and trap dirt. If true, the downside would be that you'd have to change your engine sooner than the next guy. :-) -- Blake Sobiloff http://sobiloff.typepad.com/blakeblog/> http://sobiloff.typepad.com/klr_adventure/> San Jose, CA (USA) [Non-text portions of this message have been removed]

Besides the obvious, that WD40 is garbage (only really good at cleaning, not lubrication...which really has nothing to do with the air filter anyway), filter oil is sticky, to trap dirt. WD would quickly dry up and have wouldn't last long, not to mention that being thin, it wouldn't actually trap dirt. Get some spray-on filter oil. When you grab your filter to put it back on, you'll se how much different there is between filter oil and WD. Jim

Most of it will evaporate, leaving you with a dry filter. You need some kind of oil. I used 30 wt for years, then switched to the real sticky air filter oil which is a mess. Now I'm a NoToil convert. __Arden

<><><><><><> <><><>><><><><> Larry, My short answer is it probably won't work. The longer answer is it's not sticky enough and will dry out/evaporate and let lots of dust into the engine.

Use this: http://www.notoil.com/ to clean and oil your filters. $25 for the kit. Watch for offers where no toil throws in a filter or two for free. I am still on the first kit several years later and I clean/oil filters regularly. Much better than WD-40. Just a satisfied customer. JF

I wouldn't dream of using WD40 on my air filter. Everyone knows that the only job it is perfect for, is drive chain lubrication. Running..... Capt. Bob Durham, CT USA 2006 KLR http://seniorbiker.blogspot.com/

Now Jim WD40 is not garbage. It is really good for water displacement, cleaning sticky stuff like decals, and de-greasing parts.

WD40 is really just kerosene with a bit of moly. It is not tacky so will not impinge dirt effectively. Even motor oil will be more effective than WD40 in the role of air filter treatment as the fluid portion of the WD40 will evaporate in use. I strongly recommend that you do not use WD40 for this purpose. Despite the huge following for WD 40 it really isn't a very useful product except for its original purpose which is to prevent rust on metal surfaces. It lacks effective EP qualities, doesn't remain on surfaces at higher temperatures, attacks rubber, etc. There are so many better products out there for most purposes. WD40 is a good product for flushing dirt and water out of mechanisms such as locks and such but try a product such as Wirth's spray grease inside a lock as a lubricant and the difference is surprising. Don't misunderstand my point of view as I use WD40 frequently but in a very limited role. Just my $0.02, Norm [Non-text portions of this message have been removed]

O.K., not quite *completely* useless, but pretty useless for the things most people try to use it for. Its a terrible lubricant, and evaporates fairly quickly, leaving no long term protection. It also doesn't work as a penetrating oil. A good penetrating oil is designed to flow by capillary action, which WD-40 isn't designed to do, and doesn't do. It does indeed displace water...but doesn't protect against water damage for very long, so don't use it to protect metal surfaces against rust. I once fell for the anti-rust myth, and sprayed a freshly built Jeep stroker motor with it before putting it in storage. The motor was sprayed with a heavy layer of WD-40, then covered with a plastic garbage bag. Several months later I pulled the bag off to find the cylinder walls and cam lobes covered with rust. Jim
