WD40 in lieu of grease on a seat post?

First off, I live in South Korea. So the normal givens to not apply. And South Korea is more bike unfriendly than America, so bike stuff is not easy to come by -- especially decent quality stuff.

Now, having said that, can I use WD40 on a seat post in lieu of grease? I just bought a Surly from a shop up in Seoul and, having taken the post out to adjust the seat, I noticed that there is absolutely no grease on the post. there is a wee bit on the bottom, but none on the shaft.

now, considering that i've got a steel frame (doubt the shop used frame coat on the inside), can I use WD40 on the seat post? or should I just not worry since the post is aluminum.

Don't do it~
My seatpost is stuck right now because I did and I thought it would be ok. Seems like it totally evaporated.
Aluminum + steel actually seems to be the worst for this. It's totally encrusted with aluminum oxide.
If you can get WD-40, you can get generic grease from the same place, perhaps? Or even some motor oil?

WD-40 is no substitute for grease, as it's more solvent than lubricant. As stated, do not use WD-40 in your seatpost!

Surely they have grease in S. Korea. Use automobile grease. . . .white lithium grease would work fine. It should be available in your country.

WD-40 will only leave a very light oil film. Even ordinary motor oil would be better. Any grease would be better still. I know they have grease where auto parts are sold.

Oil, grease, and WD40 all have the same fault: they will creep out from under the seatpost clamp due to the tension in the clamp. The proper stuff to use is antisieze lube. I can't believe you couldn't find it in an auto parts store or hardware store. It contains solid particles which will not flow out of bolts, seatposts, etc.

There's nothing wrong with using WD-40 on a bike provided you recognize its limitations. It is not a long-term lubricant or antiseize, but works fine as a light lubricant (e.g. brake pivots, squeaky parts) or water displacer (e.g. after riding in the rain).

+1.

Find some grease.

automotive store, grease and lubricant section, almost anything that is an oil or grease there will work.

and of course, not to mention, it's better than the alternative here, which is riding without any lube. Use WD-40 until you can find some real grease, it shouldn't be too hard.

WD-40 is more of a solvent/break-free product and not really lubrication.
Due to the severity of your local conditions, I'd recommend marine grease. You must have a boating/fishing industry in S.K.? They have to protect their metal parts from salt water. Get some of what they are using.
Also, stick with similar metals to reduce galvanic corrosion. You got a steel frame - I'd stick with steel posts and stems. And grease. And check often for corrosion.

They have cars in South Korea, so you've got grease. You don't need much and you don't need any particular type. Automotive bearing grease is good enough. You only need a small dab spread across the surface of the seatpost.
As for WD-40, I went from someone who thought WD-40 was the devil's evil twin, to someone who uses it regularly for certain applications. It's great for cleaning frames and cutting through grease on frames and alloy parts. I use it to clean the chain on the bike if I don't have enough time to take the chain off the bike, and I use it to clean out brifters and freewheels when they are gummed up. I never use at as a lubricant.

Yeah, WD-40 would work on a seatpost, if you re-fresh it once a week. Wait any longer and you risk having the seatpost corrode to the seattube. Any grease would work better. You could probably even scrape some off the hinges from the doors in your house.

You'll get by ok with grease but the correct stuff is antiseize lube, available at auto parts stores. It will never squeeze out.

Vaseline will do in a pinch . . .
But S. Korea is full of cars/motorbikes, there is grease easily available.

Anti-seize or wheel bearing grease from an auto parts store will work fine. If I were you I would consider removing every fastener that threads into your frame and applying anti-seize to them. If you can find it frame saver is excellent to apply to the inside of your frame. If not you can use motor oil.

Long term you want to pick up some waterproof marine grease for lubricating your hub bearings.

WD40 Grease or Oil.

I find each has its use, I use WD40 on electrics and i find a really long lasting sticky oil such as the additive oil used to convert ordinary petrol to 2 stroke mixture is super for most applications. Grease for Bearings and to hold ball bearings in place during assembly is essential. Just my 2 pennyworth. Ged'

The seat post wants to bond with the seat tube chemically. Lube prevents this. WD-40 does not, at least not after 3-4 minutes.

motor oil. thick viscosity.
I think lithium-based grease works well too. They can be found in any auto or boat stores.

Christ, you'd be better off with vegetable oil than WD-40 for a seatpost. I think you can make a case that WD-40 would be worse than nothing - by cleaning any residual oil off, it might actually make it corrode/seize faster.
