I've been taking my truck to a GM service shop that greases all the fittings on my truck. Unfortunately, I'm not sure what grease they use and I've decided to start doing it myself. It is dark gray in color. Any ideas? I'm willing to give them a call but I'm not sure they'll tell me what kind.
The manual calls for Chassis Lubricant (GM Part No. U.S. 12377985, in Canada 88901242) or lubricant meeting requirements of NLGI #2, Category LB or GC-LB.
I realize I can purchase an equivalent grease, but I always heard dark gray implied grease with moly. Is this the case?
While I'm at it - any brands of grease better for these GM trucks?
