I used to work in a shop that ran the Trim Micro-Sol semi-synthetic products and they went rancid FAST. They've probably improved their stuff since then (15-20 years ago), but it left me with such a "bad taste in my mouth" that I'd never go back.
I would hesitate to get 5 gallons of anything unless you have big coolant tanks and plan to refresh them with clean coolant several times a year. I say this because coolants, especially semi-synthetic ones, have a finite shelf life and could start to separate their components in just over a year. Full synthetics have twice the shelf life, if not more.
My 2 cents.
