Everything I read about greasing the zirks on the drive train indicates 2 types of grease required. Why can't I just use Mobil 1 synthetic on all the zirks? What will happen in the long run if I do? I don't believe if taken to Jiffy Lube or even the stealer that they would find all of the zirks, let alone pay attention to which zirks get which type of grease.
