What is the percentage of PEA in this High Mileage product?

Per the MSDS Polyetheramine: 10 - 30% I've come to understand that this covers all products, this one and there is a larger 12 oz product. They have treat rates that are not the same which leads me to believe that this product is likely 25-30%PEA. While the 12 oz product is ~15% PEA.

The pea is 10% to 24% for gumout. redline is 28% to 32% the only other that has pea is chevron techron all good but redline is best agree?

Per the Gumout MSDS Polyetheramine: 10 - 30% I've come to understand that this covers all products, this one and there is a larger 12 oz product. They have treat rates that are not the same which leads me to believe that this product is likely 25-30%PEA. While the 12 oz product is ~15% PEA. I can't seem to pull up a recent MSDS for Redline, but prior versions say 25-30% or <30%. So, bottom line is they are comparable on a cost per PEA basis.

Will it affect smog test if i use it couple days before?

If you want to be safe, run all that fuel out before the test. That way you will get all the cleaning benefit. Honestly, I do not think the chemicals will change the test if that was your question. The Cat converter will burn most everything.

Good cleaner

Works great for cleaning fuel system. I use it in all my gasoline cars and trucks.

Did not eliminate engine knock, but did improve it on my 2014 prius v

Backstory, I should have used fuel system earlier in my car. At about 120k, the engine started knocking, especially with the AC running. I have used predominantly Sam's Club gas, 87 octane. I never used fuel system cleaner until then (I have in my other cars, but just never did in the Prius. With the gas practically empty, I put in a bottle and only put in 4-5 gallons of gas. It definitely helped with the engine knocking. I now use it regularly (everytime the engine starts knocking again every few thousand miles.) I did originally try this on an empty tank and filled it up the tank......did not stop the engine knocking. Thus now I only put in a few gallons. Did it improve mileage....NOPE. I did not see any performance increase.
