Does a (PEA) Fuel System Cleaner exist you can use EVERY Gas fill?

After deciding to go with a tank of RED LINE in my Harley gas tank I mixed in about 4.6 oz to the 6 gallon tank with my normal "go to" Ethanol FREE 93 pure gas. Then at about 1/2 a tank the wife and I had a day to ride so I topped the tank off to full ( added 3 gallons ) and went ahead and dosed about 2.5 +/- oz more of RED LINE cleaner so I have now run 6 gallons of REDLINE treaded gas so far through the bike and still have 1/2 a tank left I will continue to ride out.

So far a few observations...
As soon as I took off with the treaded gas I noticed I'm getting a lot more Decel POP and one actual "bang" that scared the poor driver beside me.

I will hold out judgement as i'm just now getting the bike on the road after winter so it could be anything or nothing, i'll refill without REDLINE and see if things return to normal.

The REDLINE suggest it has a top end lube and I can contest to that. I normally run Marvel Mystery in my gas and notice when I do the in tank fuel pump makes les noise, with the REDLINE and No MMO for the first time I can't hear the fuel pump at all.
I put a tiny bit of the REDLINE on the tip of my finger and it has the same almost sticky feel as Lucas stabilizer ( not as think as Lucas but has a tacky feel unlike Marvel,

Except for the occasional decel pop the bike is running strong and has a smooth idle as much as a V2 will smooth idle..
I think I will run the last 3 gal out and go back to my normal gas or should I continue until I use the entire bottle? Hmmm ?

Now I feel dumb for using Techron after every oil change (which made it easy to remember to do it)…

Makes sense, now I need to revise my game plan.

Side note:
Each bottle says “treats up to 15 gallons”. My trucks have 24 and 32 gallon tanks, so each gets two bottles and a full tank of fuel. Does everyone else do similar?

I do the same for vehicles I take care of…no worries doing this for many years now...

When I used to buy ethanol free gas for my old car (can’t get it in high enough octane near me for my new car) I would add 2 oz of gumout high mileage to 3 oz of Lucas UCL (kept a few of those 5 oz Lucas bottles in my trunk with this concoction) and add a 5oz bottle of this every fill up.

Purchased on rollback from WalMart, Lucas UCL in the gallon bottle and Gumout meant this didn’t cost more than a couple $$ per fill up (old car- 2012 Camry- had a 16 gallon fuel tank).

I would hazard a guess this is close to or higher than most TT gas levels of detergent.

Now days I buy Shell, Mobil or Chevron 93 and only do a full treatment 1-2x per OCI
 
FYI, I finished up about 9 gallons of gas mixed with REDLINE PEA cleaner ( about a tank and a half) in my 2023 Harley Street Glide.

To my surprise, I don't think my bike liked actually running with the RED LINE IN my gas. Not saying it did not clean as I think or assume it did but my bike did NOT run normal while the Red Line was in the tank doing its cleaning.

I mixed per directions (about 4.6 oz to the 6 gallon tank) with my normal 93 Ethanol free gas but as the RED LINE mix was in my gas I experienced what I would call a stumbling start 2-3 times when cold 65 - 70F outside temp, Would turn over, start but almost cut off with the RPM's dropping but would stubble then come to life. Did this a few times and something my bike has never done before adding the REDLINE in my gas and once finished with the cleaner its starting normal again.

I also experienced lots of Decel Pop with that PEA cleaner in the gas and perhaps something only I would notice as a Sound Tech but my bike ever so slightly sounded different when running that PEA cleaner. My engine is not as loud or aggressive sounding, best I can explain when at idle and as I walk around the bike to listen.

Once I finished with the Redline I ran a full tank of my normal ethanol free gas and my bike is now running great with little to no decel pops and the sound is back to normal and starting the bike is back to the norm with NO stumbling...

I actually had the thought I hope the PEA cleaner didn't harm anything but it didn't.

So did the REDLINE Help anything? Hard to say as my bike was running good to start with but I think so. hope so...
 
I have a suggestion. I faced a similar question a while back. I concluded that Techron High Mileage fuel additive was the way to go. Not the Complete Fuel System Cleaner that has been mentioned several time here. The Techron High Mileage cleaner. For three main reasons.

First, the instructions say you can use it every 1000 miles, or 12 times between oil changes, which is much more in line with an every tank additive.

Second, its profile in the Chevron literature is much closer to the claims about pump techron gas that the Techron Complete Fuel System Cleaner. I will include a link to that.

And finally, in my area at least, I often find it buy one get one. Normal price here, as of 2026 is 12.99, about 14.00 with tax. That is $7.00 per bottle at the BOGO price. It's a 12 ounce bottle with roughly a 1 ounce to 2 gallon treat rate, will amount to about 30 cents per gallon, which is about the price premium on Top Tier fuel in my area.

And as a bonus, its a Chevron product. The very company that invented the poly ether amine fuel additive.

You get a Chevron additive, with a more fequent use rate, at a comptive price per gallon with pump gas. Even at full price, it would only be about 60 cents per gallon. Here is the link to the Chevron comparison of their fuel additives:

Well no reason you can not use PEA fuel additives every fill up if you can afford them on that scale! Not sure if that would be benifical all of the time.

Lucas Fuel System additive always worked decently and at affordable treat rates.

Schaeffers #131 is likewise a good option.


The real question is do you need to go that far? Benifit is much harder to figure out. What are you going measure?

How much PEA does this have?

Your SDS shows 0.1% to 1% and your dosing is 1oz to 5 gallons.

That makes it single to double digit ppm per gallon of fuel whereas top tier gas like Chevron is going to have triple digit ppm.

In Season won't do anything.

Your concentration of PEA is insignificant. It is a label claim and does nothing except enable you to claim your product has PEA. Which enables you to go on social media and recommend it alongside products that have actual effective doses of PEA.

I would think the amounts they are telling you to use on the bottle of cleaner you are using, are way stronger than any top tier gas. My understanding is that the amount of cleaner added for top tier gas isn't much. So if you are just trying to make your non top tier gas, top tier, you could probably add maybe a quarter or less of what they recommend to clean on the bottle to make your own top tier gas.

Full disclosure and main reason for my post is I use this 93 octane Ethanol FREE gas from this pump 100% of the time in my old classic Harley and most of the time in my new Harley ( when I ride local ) Its a old pump on the side of a old building, the pump looks scary with the front bolts loose and makes a strange noise when it pumps and takes forever to prime from the underground tank.

Why do I use it? It runs fantastic in my bikes, My old bike sits in storage well with this pure gas filled to the top and my mix of Sta-bil and Marvel Mystery oil in the gas.

I'm not a fan of ethanol in classic anything. I do have newer ethanol free pumps in my area but all are 89 or 90 octane. My new bike pings on a hot day with anything under 91. This 93 will not ping. I have used this pump gas a solid 3 years and never felt like I got a bad run of gas...

Its one of only (2) 93 octane ( NO CORN ) pumps in my entire County and only a few miles from home.

But its no name gas and I have no idea what detergent it may have or not?

The idea of IF I could add detergents in every fill got me thinking why can't I?

$4.19 ?!?!? REC90 is like $6/gal in my area at the moment.

Thanks for that. I just bought the high mileage. There are a few things I thought it did that it does not.

Back to the complete.
 
Apparently;
"The exact ratio of Techron in Chevron pump gas is a closely guarded, proprietary secret. However, industry consensus and automotive enthusiasts estimate that regular Chevron pump gas contains about 8ml of Techron per 3.78L (1 gallon), or roughly 2ml per liter of gasoline."

So perhaps you could just add a small amount of Techron per fill up to equate this in your standard gas? Or maybe do a similiar method with Royal Purple Max Clean or BG 44k based on estimates of PEA concentration in the product to the amount of fuel you use in each fill up. Just a thought
 
Never go wrong!

That table color looks just like mine. Had to do a double take.

I just put some Amsoil PI in my Legacy since it treats up to 30 gallons and I'm gonna use the Redline SI for the Impreza since it treats up to 20 gallons. The Legacy has a 18.5 gallon tank and the Impreza is 13.

I did not add to an empty tank though. My wife had already filled up before she got home. I figure with the fuel bouncing around in the tank while driving it will mix and have her drive until almost empty, she'll be fine.
