Got conned first time in many years.

What is Dyna lube used for?

Dynarex DynaLube Lubricating Jelly is designed for medical purposes to lubricate instruments or orifices, assisting in the insertion of devices for diagnostic and therapeutic purposes. DynaLube also provides lubrication for hinged instruments, while enhancing and protecting the internal parts of the handpiece.
You can say what you want about Dura-Lube but my old B250 Dodge van had a ticking lifter. Had a 318 LA motor. Put in Dura-Lube and lifters are still quiet to this day. Whole motor runs very quiet.
