6oz Gumout bottle says 21gal gas, 12oz bottle says 19oz?

[Ang]

Paid $6.50 for a 6oz Regane bottle and the top left says 21 gallons of gas for the 6oz bottle.

Now ive just found that Somehow Autozone has a 12oz bottle for only $7.50, It says Regane but only says pea on the website, not the bottle label, And the bottle says 19 gallons of gas in the bottom right? so do i stick to the smaller bottle as it claims to be for more gallons of gas for a lower price?

They also have 24oz of Techron Complete for $12 which claims 24 gallons if that would be better.
My car is reporting a small amount of misfires, about 100 per minute or so when holding 2000 rpm at idle. it doesnt do it when driving. so i planned to add this along with testing the coils. i guess theres no actually useful cat cleaner to add as well.

Fuel system cleaners are very powerful and highly concentrated chemical mixtures. I once bought a container of top tier additive from the supplier and it was mixed at some crazy ratio of 0.5 ounces per 15 gallons of fuel. It was a crazy lean ratio.

These off-the-shelf fuel system additives are the say way. Most all of the product in the bottle is simply carrier additive put there to mix the active ingredient into. Also, the packaging is done in a manner to make it difficult to compare pricing between different retailers. The Auto Parts store may sell a 12 oz bottle while a WalMart store may sell the 6 oz bottle. One takes up more highly valuable shelf space while the other gives the illusion that you're getting more product and therefore willing to pay a higher price.

The reality is that it's the same amount of active ingredient packaged and marketed through alternate retail channels. The wise consumer does as you have done and reads the label and compares pricing to treatment rates.

So the larger bottle which rates less gallons of gas is less than half the concentration (being a 2x the size bottle) and that's why it has slightly different branding of replacing pea with carbon clear? so everything just needs to be compared by price to amount of gas it can be used with?

Even Chevron is doing this. walmart is a 10oz bottle stating 15 gallons, everyone else is a 12oz bottle stating 12 gallons. a 7 year old post here claimed walmart was wrong or old stock at the time, and they still have those 15oz bottles today.

Which product are you refering to? PEA is active in both Regane and Techron. It is THE cleaning agent in fuel injector cleaners. For example, PEA is not mentioned on the bottle of Techron that I have and neither is it mentioned in the Safety Data Sheet but if you peel the label back on the bottle it references it. Gumout Regane does advertise it and makes it known that it's the active ingredient in their Regane product line along with a nice doseage of PIBA (polyisobutylene amine).

But yes, the concentration of active ingredient will be dictated by the treatment ratio. My $5.49 bottle of Chevron Techron that I bought at NAPA is 12 ounces and yet only treats "up to" 12 gallons. There isn't a huge amount of detergent in this bottle.

Autozone has 2x for $12 of the 12oz 12 gallon bottles. walmart is $10 for a 10oz bottle which states 15 gallons of gas. this is for Chevron Techron Complete, which ive been looking at right now over using the gumout.

I’ve never bothered trying to make sense of how many oz’s treats how many gallons. Just dump the entire bottle in the tank and away you go!

I'm more looking at price to concentration not about overdosing the car by a few oz.

Yeah on price alone Regane is hard to beat. I cycle between it and Redline mostly. Chevron gas is super common here (ATL) and they advertise Techron on all grades so that’s my normal fill up.
