kingrob,
I really didn't want to offend you. Sorry.
You and your chums will find that things last when they are properly lubricated. If you are lubricating your chain once a year, why even bother?
You posted recommending a particular lubricant, yet there is no way possible for you to have any idea how it performs. You don't use it as prescribed by the mfg, nor anywhere close enough to be able to form an opinion.
If you have cans of lube on the shelf 10-12 years old, they sure aren't Super Clean. Maybe you should have given those other lubes a chance.
You might have found that the Super Clean is in fact a cleaner lube than the old Belray stuff, but still lacks what it takes to be a superior chain lubricant.
