This discussion relates directly to a subject that is one of my pet peeves regarding hobbies and specialty products. There is no end to the examples from almost any hobby you might have. Manufacturers take a commonly available product, repackage it so it appears targeted at a specific application and then jack up the price to multiples of the original product.
No doubt there are many quality lubricants out there that cost a fraction of what the "reel lubricants" cost. Also no doubt that the "reel lubricants" are the same products you can get under other labels for a fraction of the cost. They are just relabeled and repriced.
I agree that you should make sure you use a quality product to keep your expensive reels maintained. But it also annoys me to no end that they expect me to pay a ridiculous markup for something just because they gave it a different name. >
