Regular standard hi-temp dino grease is more than fine.
If you don't race the car, you rarely need to grease those toe links ends.
I originally purchased a tube of Mobil 1 for this purpose and it continually dripped all over the inside of the wheels until I flushed it out and replaced with good dino grease. Many other members had the same experience with Mobil 1 grease. It may have just been a bad batch, but... I think I'll stick with dino grease anyway.
So far with the dino grease, zero drips and holding up just fine. After a year and about 10k miles, the boots are still plump and the grease inside still appears like new.
Just like the non-greasable toe links on the non-Z51 cars, if you do not track the car, you can probably get away with never greasing the links ever and they'll last the life of the car.
When tracking the car, I believe the concern is that the extreme high heat emitted from the rear brake rotors is what will kill the toe link grease (as in stomping on the brakes at 100 mph every 30 seconds or whatever, continuously)... but if you're not tracking, this is not a concern and the grease in the links should last a good long time.
Mobil 1 drips. I bought a grease gun and loaded it with Mobil 1, but pulled back the leaver so it's not under pressure. Hung it on the wall in the garage because I'm not ready use it yet. A few days later I see this purple crap all over my tools and it was the grease gun dripping the purple Mobil 1 grease. It was 100+ degrees this week, but it proves it drips.
Haha. I think the list of things that people can never agree on goes likes this:
politics, religion, and lubrication
What I'm getting out of this thread is: people use Mobil1, Valvo synth and others. Nobody is having massive suspension failures with either, but several people say M1 drips.
The dripping is caused by the oil separating from the soap base. Most greases separate to some degree, but the Mobil 1 seems to be excessive.
I went with Valvoline synthetic to avoid the problem many were experiencing...it meets the required lube specs and says so on the tube. The Valvoline also will leak oil residue out of the gun, but it doesn't drip on my wheels and that's what I meant to avoid.
