John, you are welcome. I thought the link might be helpful. It actually contains some technical discussion alongside the ubiquitous opinions. I thought the discussion was helpful at the time (3 years ago), and it still is the best discussion I have seen on the topic.
One tube of high-quality grease will last for a long time. My practice is to gather up a bunch of those little glass jelly jars that now appear on breakfast buffets in nice restaurants. I wash them and refill them with grease from the big tube. The tube is cardboard, so you can trim it down as you take out the grease. That makes it easier to handle. I put the little jars of grease in all my gun cases, in my range box, and in every convenient location. I always have grease at hand, for very little cost.
