So considering various greases and their water resistant properties. Generally speaking and also in regards to use in PU bushings. I've used Valvoline red grease in the past with poor results. More recently I'm been using Super-Lube with OK results. I like the fact that the Super-Lube should have zero effect on the PU material... but not sure how much that matters since its supposed to be petroleum resistant to start.

In any case, re-lube interval is rather low, and must be done after any rain storm or squeaking will result. If I were to add lift shackles in my DD truck, they would have a PU bushing on one end and I would have to absolutely minimize lube frequency.

Looked up specs on 10 different grease which claim to offer waterproof or highly water resistant properties. Super-lube is rated #2 on my list with an ASTM D1264 of <1.0%. It is surpassed only my Mystic JT-6 Marine at 0.90%. Most of the offerings from Amsoil range between 1%-3% and CRC's Sta-Lube marine shows a whooping 5% water wash out! Green Grease (unsurprisingly) doesn't publish this specification but I did shoot an email.

Obviously trying to avoid anything too boutique, lets say less than or equal to the MSRP of a 14oz cartridge of Super-Lube as a base line. Is there any better grease out there than Super-Lube for PU bushings? Anything with a D1264 score better than 0.90%?

Lucas marine and Green grease are both lithium complex, easy to find and and reasonably priced. I have used them both and would go with either one. Green Grease is the stickiest, clingiest and tackiest grease I have ever used. It is also very long lasting and makes things operate very smooth. Green grease comes in 3 and 14 oz tubes at autozone, advance auto and a few other places.

Lucas marine grease is good too but it has more of a smooth, waxy texture that seals out water. However, Lucas marine bleeds out of the grease gun pretty badly where the bleeding is very minimal with green grease.

For me is not clear what do you want.
Water resistant grease or grease that withstands spray offs.
They are two different types of greases e.g.
1. steel and paper mill greases has excellent resistance to sprayoffs,
2. marine grease works excellent with presence of water. Than marine greases are devided to two
a. types that absorb water E.g. Calcium based
b. greases that repels water. e.g Aluminium/Barium based

I was about to relube my PU bushings with Loctite's ViperLube, a calcium sulfonate-based PAO grease that has on paper a 0.5% water wash score, I got it on Amazon but then I got rid of the car in question and I still have the tube. Loctite claims it should be compatible with polyurethane.

For water resistance I like Bentonite based greases. I have one that sticks like crazy and does not mix at all with water.

Amsoil synthetic water resistant has worked well for me in trailer bearings that are often in saltwater.

I do too. and if you get a bentionite grease with a PAO base you won't get any rubber swelling on top + excellent high temperature stability.

The D1264 water washout has the options of running at 38C and 79C (100F and 174F). The greases with the higher loses are run at 79C according to their PDS's. The greases with the low loses are either run at 38C or their temps are not specified on their PDS's. With such low loses the lower temp is assumed. The comparisons are not really direct.

Bentonite (clay) mixes well with fresh water but not as well with salt water. Must be a low percentage anyway ... and encapsulated in the HC base ...

The best grease for polyurethane is grease made for it. Energy Suspension 9.11110 part number for the Formula 5 lube. If ES swears by it on their bushings knowing they offer a warranty for bushing failure I would trust it.

If you don't want grease specific for poly like the ES recommendation. Any full synthetic grease like Mobile 1, Amsoil, etc will work just fine.

I had a [censored] near full Poly Urethane front and rear on my Mustang 2003 GT for years as a daily in Tennessee and never had a squeek I heard. Control arms, swaybar bushings, and so on. No issues that I heard over the exhaust

Silicone paste is the right choice, 3M, Energy Suspension, etc.

It does not separate, will not thin on hot days, D1264 0.25%, and the cost is justified for other uses. You should not have to reapply it after every rain. If that is the same result you should machine a grease channel reservoir in the bushing or bracket and pack it in. You don't need much.

Not a cartridge but frankly that is not necessary. These are not fast moving parts and relube interval should be very long. Use less grease in total, and save money and time even if it costs more per oz.

$20 for 8oz on Amazon.

The Energy Suspension Formula 5 is also silicone and cheaper at around $17 delivered for 8oz.
