The bottles of Techron I have are the 20 oz. bottles which indicate they will treat 20 gallons. This equals 1 oz. / gallon.
My recommendation, based on information gleaned over the years from various sources (trust it or not, it's free advice and definitely worth at least what you're paying for it) is to use 1 oz. / 10 gallons as a continuous treatment dose. This is 1/10th the dose recommended on the bottle.
What makes you think 1 oz. / 10 gallons is higher than the amount in pump gas?
Edit to add:
If you are too lazy to Google it, here's what Chevron has to say on their Techron web site:
What is the difference between Techron® at the pump and Techron Concentrate Plus in the bottle?
The principal difference is additive concentration and rate of deposit clean-up. Gasolines with Techron over multiple fill-ups will help clean deposits on intake valves and minimize harmful combustion chambers deposits. When added to a full tank of gasoline, a bottle of Techron® Concentrate Plus results in an additive concentration roughly 10 times stronger. This mega-dose of Techron provides a much quicker clean up of intake valve deposits left by lower quality gasolines. In addition, the high concentration of Techron reduces combustion chamber deposits, which can help eliminate deposit-related engine knock.

I was actually thinking perhaps a little bit lower. There's already at least the EPA mandated amount of detergent in fuel. Most would be synergistic since they're similar in makeup (usually PEA).
And if you're already using a fuel that's advertised as Top Tier or that's advertised as having a high dose (Costco Clean Power) then it may not be necessary.
