Autozen, I have a '93 300e and an '85 190D that I service regularly. My question on the lube is for the zerks on the ball joints, steering parts, etc.
I also have farm equipment and other vehicles (phords, chivvies, chryslers,
and a Jag or two). I hate to have a special grease gun for each vehicle so I was looking for products that would work for all or most of the vehicles and equipment.
Thanks
Al
