OK so which grease should I use for my new '06 Silverado Z-71? I have some Mobil 1 Synthetic grease....is Mobil 1 a good grease to use? I've read a lot of good things about Schaeffer's and Amsoil. I've read a lot of posts complaining how Mobil 1 grease separates and runs all over. Just want to make sure I'm using a good high quality grease.
Thanks!
