Many new vehicles do not come with fuel filters. The sock is all we get. Everything is supposedly filtered out at the pump. Anything that gets by the 'sock' will be pulverized by the fuel pump in order to pass by the injector. Times have changed.
MSDS doesn't give a recipe of products. I've blended 100% distillate FI cleaners with varying ratio of PEA/PIBA and never did list them in the MSDS. So, please don't use an MSDS as some recipe or ingredient list. We don't have to list anything. MSDS is for environmental and medical personnel usage, and they can call for treatment or clean up info.
There are many Techron products with varying degrees of PEA and at various price levels.

I guess that most additives are useless. Make you wonder why the EPA lowered the standards for fuel cleaner additives to give consumers cheaper fuel, all the while causing issues for certain automakers. TOPTIER pretty much maintains the original acceptable fuel cleaning standards that many automakers agree on.
I don't know of any carb/choke spray can cleaners that advertise having PEA. Keep scrubbing. Different types of deposits in different areas. Surfactants have their place in history. Some of these additives work with 'flow' and 'pressure' and 'temperature'. I'm not sure what to expect by putting a drop of PEA based cleaner on some crud. Where's the movement, heat, or action?
I've never seen ANY fuel additives cause a vehicle to kick and buck like a mule, even when used against label directions. Obviously, the root cause of the issue was never found but its even to blame a bottle of 'whatever'.
Besides PEA, PIBA is another. Variations of both, along with numerous other chemicals, are used by the fuel companies and marketed as 'whatever fancy BS' that you can read at the pump. These can be added right to the tanker truck or station tank. So, don't assume that identical delivery trucks fill your local no-name station with the same good stuff that a toptier station gets.
Lets not use silly terms like paint thinner, naptha, toluene, PEA, solvent, distillate,... unless you have some chemical background and work for the company. Most fools use inappropriate terms as some type of debate 'facts'. Ester... my truck ran on ester, had ester lubricants, and had most of its mechanical parts washed in an ester filled parts washer cleaning tank... all the while I was enjoying all the flavors and fragrances of the esters added to my food and drinks. The glycols are also in some of my favorite beverages too.
Get a job as a Chemist, ChemTech, or Chemical Engineer for one of the chemical or product companies and learn something. Even bench cleaning/testing fuel injectors, with some of those chemicals, can teach you a thing or two of what does or doesn't work, and who is using good fuels or injector cleaners. Most people won't notice bad dirty injectors until they fail an emissions test, have a SES/CEL, or wonder where the MPG went. If they're lucky, but they might feel a loss in power or a not so smooth idle, or hard to start when cold/hot situations. World is full of Zombie drivers that surprisingly can usually tell you the exact spot where their cell phone service disconnects, or GPS hangs up.
I recommend toptier fuel when available. If you use a toptier fuel, the odds are that you'll never need an injector cleaner.

If Toptier is not available, use a busy station for 'fresh fuel'.
If vehicle is stored, or you don't use a full tank of fuel every month or two, invest in Stabil or equivalent fuel stabilizer.
I've never seen anything but positive from various fuel injector cleaners. Redline, Amsoil, Techron, Regane, RoyalPurple, BG44k, 3m... are some.
For certified injector cleaning along with spray patterns and flow rates, send the injectors out to a shop that specializes in cleaning them. Or, find a shop that does a motorvac decarbon that T's into your fuel line, disables fuel pump, to really clean the injectors and anything downstream of them. These fuel injector fuel system services were excellent prior to toptier. Looks like the new direct injection issues will be bringing newer versions of the fuel system cleaning. DI is a whole different ball game compared to carbs and port injectors.
And yes, when measured in PPM, many additives have a range where they work. So, even when a bottle with a dose of carrier chemicals is introduced to your 18 gallon tank, the PPM range is still acceptable for them to work at a given rate. This is why you should read the bottle on correct usage.
