Here's what the folks at Star Tron had to say -
"Hey Warren,
You can use either one, the only difference is just the concentrations, and one bottle has more enzymes than the other one and therefore can treat more fuel. If you are comfortable measuring smaller volumes when using the 1oz to 16 Gallon then by all means use this one, it tends to be the more cost efficient route.
I hope this helps, if there is anything else I can help you with please let me know, and thanks for choosing Star Tron!"
If you plan on "long term use" (justifying the purchase of a large bottle), sounds like the quart size for about $30 would be a good choice. Using Star Tron's 1 to 16 calculations (for their "standard formula"), (HERE), about 3 1/2 capful's will treat a "typical" 5 to 6 gal "fill up".
I hope this "exercise" has been useful... :Shrug:
