First of all there is nothing to lube on the two MBs you mentioned unless you special ordered them with lube fittings which I don't think you can do. Secondly I think you are making too much of this and fretting for nothing. Go down to the automotive store and get some tubes of good old chassis grease. Since there is such fearce competition in many markets today, MFGs are making up advertising gimmicks to sell a virtually unchanged product. It probably started in the 50s when everyone had a blender on the kitchen counter. One company got a slick idea to throw a diode inside that did nothing, but they could then call it SOLID STATE. Before synthetic grease came on the scene, wheel bearings have been packed in GOOD OLD GREASE and all the wheel bearings in the world have travelled billions of trouble free miles.
