Hey Nige. It would be hard for me to answer on the price, as I'm getting a reduced price from Belray for buying in fairly large quantities (like 12 5-gallon buckets at a time), and I have to pay freight and import duties on it. I get it from them for around US$135 per 5 gallon pail. For me, the CAT grease is much more expensive, as I would buy that locally, and the local dealer has to make his profit and then some, so he sells te CAT Ultra 5 Moly for CI$255 per pail, which is US$318!!! CAT parts and service here are beyond ridiculous, which is why I only own Hitachi/Deere machines. I guess that's what happens when you buy a large franchise for a small market.
I only bought the CAT grease once (when I ran out and was desperate) and it worked good, but I still don't think it is as good at staying in the joint as the Belray High Viscosity Moly, and cost me twice as much. Plus, the Belray folks (like Blitz138) give me real good customer service, and I believe in that, so I'm sticking with Belray.
