If I were prudent, it would be at the end of the oil drain as that's what the literature is suggesting is best practice.
For now, the plan is to run it for the whole interval as the ultimate goal is to remove discoloration which isn't something I think we've seen with other cleaners. Chevron suggests a higher concentration is needed to achieve this and I'm not comfortable testing over 5% with this car.
My hypothesis is running it for a long time at 5% will give similar results to doing short runs at 10-20%. We'll have the UOA @ 300 miles to see if it's a good idea and the next UOA will be 3000 miles.
Will make threads with the results once they're received. First one will be sent next week.
So the main issue is it normally only comes in a 5 gallon pail.
Chevron sells direct for $278USD. Might be able to use coupons, not sure.

Their distributors also sell it. I was apparently the first to inquire in Canada and was quoted $800CAD / 579USD....
After a ton of research, came across a video showing they sell a 12 x 1 liter package in China. It's not sold anywhere else.

Got two bottles for $27 each.
Because of the risks (potential trouble from customs if inspected), buying direct from Chevron's website and splitting the pail is the way to go if the experiment works out. 5 people could get 3 litres for $55.

Wish we could ask for more information but they haven't logged in since 2021. Not going to bother to look at their post history more than I have but they seem to have posted a lot about Chevron products in the past..
