What is good PEA based cleaner for 2023.

RoyalPurple MaxClean
Amsoil PI
STP 5 in 1
Lubegard Fuel Booster
3m Fuel system cleaner
Lucas Deep Clean or their Complete
BG 44k

Don't get hung up on PEA. Plenty of other chem can clean injectors and reduce carbon deposits. Berryman HEST and Seafoam are a couple others too.

And, if you don't want to buy any product, just go to Shell and fill up with their vpower nitro+ premium fuel, which has 7x the cleaning agents when compared to Fed standards(EPA fuel). Its easier than throwing darts at the numerous products available.

That's why Regane is nice...it has more than just PEA. =o)
 
Redline Si-1
People are welcome to consider I'm full of it but I purchased a 09 Accord last year, 200k miles, but it was $800. Needed a bit of work, 2 struts, a wheel bearing, pads all round, and 2 rotors.

Granted for the price I considered it very much worth while, so I jumped on it. I don't regret it however I did learn the car was getting about 21 highway (90% highway driving). It was also burning oil, car had a very high negative fuel trim, I replaced the coils, spark plug, oxygen sensor, and PCV to try and help with some of these issues.

Absolutely no change what so ever, so I than turned to gumout, ran two tanks of their regain, nothing, ran Berryman, nothing, I tried a bottle of Gumout Multisystem Tune-up .. still nothing. Long term fuel trim anywhere from -15% to -19% short term normally sitting around -12%, and this stayed constant after doing the tune up.

Give plugs/oxygen sensor made no difference I looked at the MAF, wasn't giving me any issues, still I cleaned it. The car was still sitting at 21 highway, and I was to the point I was suspecting fuel injector issues. I tried Redline Si-1 because I knew it had a higher dose of PEA and figured not much to lose at this point.

That very first tank I got 23mpg (mostly city driving), later tanks 25mpg 90% highway, I've put about 6 tanks of gas in the car since using Redline Si-1 and 25mpg has stayed true. I did try a second bottle of the stuff just out of curiosity, didn't make any difference.
My conclusion is Redline Si-1 did something no other cleaners I tried could do, it made a difference in the car, fuel trim fell back in line (not perfect) but rarely above -7 -10 long term. Could it have been a combination of all these cleaners back to back? Possibly, they might have all done something before trying Redline Si-1 only for it to get the credit.

But I ran multiple tanks of gas through this car and never got better than 21.5mpg (90% highway driving to work) car's rated 30, it was getting well below, I do know I will never get 30 but 25mpg average after maybe 8 tanks straight is a difference, and every tank after has been far better than even my best tank before using it.

I measure MPG but mileage travelled, divided by refill gallons.
 
I have had wonderful results with pea based cleaners..I can honestly say I like the gumout series (regane), redline si-1 but if I have to use deep clean from Lucas or techron or anything with the pea I am okay with it. I used the Gumout multitune in the tank, scrubbing the throttle plate as well as a meeger 3-4 ounces in the crankcase to idle for a few minutes and all was well
 
I will Techron complete fuel system cleaner. 2. Redline s-1 3. Gumout high mileage regane botttle.no improvement then I will solvent base Berryman b12 last resort.
 
Anyone tried this?
Was on sale...

G 001780M3 at VW/Audi dealers ~6.75 ounce bottle and 75-80% of the good stuff
Do you have a reference for the 75-80% information? That's hard to just believe without seeing a reference.

My dealer sells it for $20, is that a good price for that amount of PEA?
Yes, if it is in fact 75-80%PEA the cost per PEA is on par with others that are more widely available.

There's an english sds from 2012 that says 75 - 80% and a foreign sds from 2021 that says 70 - 90% of PEA (oxirane 220795-29-9). It looks like redline si-1 fuel system cleaner uses a different PEA in half the concentration but twice the size, and is a little cheaper if I don't want to drive to the dealer to pick up.

10-4
Yeah Redline and Gumout are similar price per ounce ~$1/ounce and have similar PEA level ~25-30%.
So yes you are good with Redline.
 
Does Gumout Regaine still have P.E.A.?
Label doesn't mention it anymore, saw some bottles in person in stores, on Amazon and manufacturers website.

Well. Their website and MSDS still mention/list PEA in the same concentration.

But then the new bottle mentions CarbonClear - and the below information can be found about it:
The ALL NEW CarbonClear technology combines the PEA cleaning power you have come to trust with PIBA, and a patented technology for a better clean. The combination of the 3 detergents work synergistically to provide better cleaning power (new formula) vs. just PEA alone (old formula).

....so short answer is yes, it contains PEA, but long answer is it might be different.
