General question about lubricants.

[pjgratz]

This is a very general question and Im not sure where to fit it. In reading the posts about how to fix some of the creaks etc it seems like part of the general maintenance now should include the lubrication of various parts - seems pretty logical and straight forward.

However, the range of lubricants(high grade grease, silicone sprays, Kryloc, graphite, oil-based ie WD40, and so on) makes making the choice difficult. Each one has a specific purpose and there are no recommended ones. I dont know where to begin and I wouldnt want to ask for each specific application. I figure there has got to be a book, a site, a sticky note post or archive that has a comprehensive overview of this.

I figure on the Boxster alone you got the rails for the top, clutch pedal, door jam, and window seals. Some TSBs say Kryloc others say silicone lubricant.

Well, I don't know if this helps or not, but here are my experiences.

I have an annoying door jamb creak that I cure--albeit temporarily--with a WD-40 coating. It's gross. I just open the door and spray it on both surfaces. But it doesn't creak for a good while.

My clutch pedal also has a squeak that I cure with WD-40. It's hard to get to the source (even with the little red straw thingy), but it sure helps it and it lasts for weeks.

That about covers it for the creaks and squeaks in my car. With the exception of the convertible roof frame. But that doesn't bother me--and I really wouldn't know what to do about it anyway.

The door jamb creaking is by far the most aggravating to me. I would love to find a permanent solution (rubber stick-ons? what?). I agree with you that it'd be a really nice Porsche-customer care thing for the dealer to give the cars a complete lubricating when it's in for service.

the dry lube Kryloc can be used on all convertible mechanism, window sills, rubber mating surface etc. i think wd40 is a solvent that shouldn't be used on rubber. silicon maybe ok but is messier compared to Kryloc. whenever my dealer fixes my top for noise, i get kryloc residue so i know that's what should be used on most areas.

door hinge, jamb, hood latch etc can be sprayed with silicon or wet grease.

my advice is not to use wd40 since it's bad for rubber and tend to dissolve the grease you have left. it may fix the noise temporarily but it'll come back.

I agree. I always understood that WD40 was a solvent and a cleaner more that a lubricant (unless one has a need for a very thin, light duty lubricant). For door hinges and similar joints (top, trunk lids) I've always used bicycle chain lube.

Oh and read Kryloc as Krytox...I think Kryloc is like a cement sealer/waterproofer or deck sealant.
