Absolutely.
I guess i'm not certain what you're trying to accomplish. But I will try to add my 2 cents.
In this post I was trying to discern PEA dosing recommendations. At the time Techron's SDS said 25-35%. With a very high relative treat rate.
Now they dropped it to 10-20%PEA, which I can confirm is what the MSDS lists today, so it is more in-line with the others, but still higher.
I seem to recall a product...but I can't seem to find the exact same thing as I believe I remember. There was a Techron fuel system cleaner in a 32 oz bottle, but it really seems like it only took a few ounces for an entire gas tank...the bottles I find now in 32 oz say add 1 oz per gallon, so...

I would feel safe using more of a maintenance dose regularly and not the full dose that Chevron Recommends.
IE: Full dose is 1oz/gallon. That worked out to 0.3oz PEA/gal with old formula, 0.15oz PEA/gal current. And current recommendations is 2x per oil change.
1/4 to 1/2 of that seems appropriate if you want to use it more often, depending on how often.
1/4 oz/gal = ~0.04oz PEA/gal, could use this every fill up probably
1/2 oz/gal = ~0.08oz PEA/gal, could use this 4x per oil change.
What I'm trying to accomplish is the proper maintenance dose and the proper cleaning dose for my car since the manufacturer's recommendation has not been consistent over the years.
From 2011 to at least 2019, techron recommended up to 5x per oil change.
In this time period, dosage was between 15%-60% PEA.
From 2011-2015: sds showed 15-40% PEA
2015-2016: sds showed 30-60% PEA
Your post was in 2021 and it showed 25-35%
We agree today it shows 10-20% PEA.
My hypothesis is it's been lowered for two reasons: Cost savings for them and the fact that many cars on the road are direct injection.
The Chinese seem to have a consensus that when it comes to pure PEA -
For a port injection engine:
-Maintenance dosage should be 0.13oz per gallon of fuel
-Cleaning dosage should be 0.38oz per gallon of fuel
For direct injection:
-Maintenance dosage should be 0.06oz per gallon of fuel
-Cleaning dosage should be 0.26oz per gallon of fuel
----------------------------------------------------------------------------------------------------------------
The Chinese recommendation is vastly different than what you wrote, unless you have a direct injection engine and want to do maintenance dosages:
IE: Full dose is 1oz/gallon. That worked out to 0.3oz PEA/gal with old formula, 0.15oz PEA/gal current. And current recommendations is 2x per oil change.
1/4 to 1/2 of that seems appropriate if you want to use it more often, depending on how often.
1/4 oz/gal = ~0.04oz PEA/gal, could use this every fill up probably
1/2 oz/gal = ~0.08oz PEA/gal, could use this 4x per oil change.

From what I understood reading different threads on here, fuel distributors have a special version of Techron that is concentrated.
We have a screenshot from one facility showing a treat rate of 0.06oz/gallon

We have another thread where someone mentions all grades of chevron gas has about 0.03-0.05oz of concentrated Techron per gallon
I'm guessing this is pure PEA with a negligible amount of antioxidants in it.
-----------------------------------------------------------------------------------------------------------------------------------------
So if I'm right about the concentrated version of techron being pure, then what some of us are currently adding is a maintenance dosage and not a cleaning dosage.
Based on old recommendations on when my car came out (2016):
IE: Full dose is 1oz/gallon.
In 2016, there was 0.3oz - 0.6oz of PEA per oz of Techron
So that's x10 what Chevron was putting in their fuel which sounds like a great cleaning dose.
vs
0.1-0.2oz PEA/gal current
