is opti-lube ok for marine diesel engines ?

Yes, it can be used in all Diesel engines including Marine applications.

How often do I have to add to diesel?

I add 2-4oz. with every fill up. I add 4oz+ when I fill my 50 gal auxiliary tank. The product comes with recommended treatment per 10, 20 etc gal of diesel fuel.

How long does this store for? I have a tiny 2 liter diesel with a 14.5 gallon tank. I expect this to last me more than a year.

You can expect the fluid to last 4-5 years depending on storage conditions. The bottle itself may not last that long so you may have to transfer into something else after 2-3 years.
