Mobil 1 has a synthetic grease and it is red. Motorcraft's PTFE lubricant is also red. Neither of these would be a problem using with rubber or poly. You want to stay away from anything that is mineral based for either rubber and poly. I don't know their effects on other synthetic rubbers. Energy Suspension Ultra Grease (gorilla snot) is by far the thickest and the hardest to get off your hands, so it should last the longest. Over time, all of these lubricants will eventually wash out. It may be years down the road, but when you start getting squeaks out of your sway bars, you know it's time to lubricate them again. Some bars have bushinsg with grease zerks which make the job a lot less time consuming. I'm not sure about the mount bushings, but sway bar bushings will eventually dry out. We get a lot of rain here, so that may be a factor in my case. Poly can also cold flow and become permanently distorted over time, so they should be periodically inspected. I've seen it in aftermarket motor mounts and suspension bushings more than enything. The great thing about many of these options is they can be reversed fairly easily, so don't toss your stock components away.
