So I rekon use can use just about anything. My dog has a cold, so I thought I'd use some of his snot to see if I could save 3 cents.
That's the problem with these types of threads. Positive annecdotal evidence is practically useless in this context. Some folks may like Brand X, but they lube their slide every 50 rounds even if they're at the range. Others may like Brand Y and they haven't ever cleaned their guns just slap some grease on it once a year whether it needs it or not. It's all out of context and with no frame of reference, no qualitative analysis can be done. What threads like this need is that "I used Brand Z and my slide became sluggish after X rounds". Do they use clean buring ammo or dirty ammo? Then some real comparisons can be used.
Just as a generalism, with no scientific evidence to back anything up, I use this guideline. I oil things that turn and grease things that slide. I find that multi purpose products tend to be too general. Take CLP for instance, it does 3 things pretty well but isn't outstanding at any of them. If you're humping an M60 across the desert and you need some lube, CLP is great and it beats carrying 3 different products. I believe this. If you keep your guns reasonably maintained you can prolly use any decent oil and any decent grease to great success. Over the years, I used oil and grease on slides and bolts at different times in my life. I don't believe I've ever had a slide or bolt malfunction on me because of lack of lubrication.
