I'm not familiar with the product you mention, but Labelle has a product line of synthetic, model RR friendly lubricants. I asked around at the Z-scale convention and Labelle 108 or 102 were almost unversally recommeneded. I've been using 108 as a lubricants for my Marklin F7s, which had the "hardened oil syndrome" and have so far been happy with the results.
