Lot of talk about Gumout's "All in One" going on here. Proof of any PEA? Regane trademark on the bottle?

Gumout® Regane® Complete Fuel System Cleaner - Regane trademark? Check. MSDS listing? Check
Gumout® All-In-One® Fuel System Cleaner - Regane trademark? Nope. MSDS listing? Don't see it.

The "All-In-One" is being compared to techron as more cost effective. Why I'm mentioning this.

I agree with most of your reply so I did not quote it. Are you suggesting two half bottle dosage of Gumout Aii-in-One for two consecutive tanks?


For something that is neglected yes and if the tank size is approx 17.5 gallons, as the bottle treats 35 gallons.

On something neglected, your butt dino should tell you when there is no further improvement. On my Taurus, I noticed no further improvement on the third dosing.

The big 35 gallon dose bottle is also useful to treat 2 different cars at near about the same time. The 21 gallon size is most likely to be used once.

GM3800 Gen II with Delphi 19lb steel bodies.
I matched them with the Asnu flow bench and he installed them.
All were within 0.5% of each other.

The originals were showing signs of internal corrosion due to ethanol and were beyond bringing back to within 3% which is OEM tolerance.

I advised him to run the Redline 1oz per 10gal of fuel to prevent this happening again. He agreed and did just that.

2 years and 40K later the LIM developed a leak and the injectors needed to come out. I asked him if i could have them to test figuring this would be of some value as to the products worth. He agreed.

All were exactly the same as i tested them the first time.
I compared flow data from then and now, its identical.
Optically the business end of the injectors were perfect, no carbon, varnish. Internally no corrosion present and shiny clean.

Granted i didn't test Techron or Gumout but i know this one works as advertised.




Interesting, I deviated from top tier / Chevron as I thought I would probably be ok with an annual treatment from my stash, but I might revisit that now.

Thanks. So now its even more confusing. The word Regane means nothing in relationship to PEA. Some Gumouts that have PEA list PEA in the MSDS, some Gumouts that have PEA DONT list PEA in the MSDS. All we have is this one Q&A on gumout's site. Would assume somebody verified the answers.

I recall all of the PEA based cleaners having that characteristic smell to it. This was true with Techron, Redline. Regane, 3M etc.
 
This car had about 92K on it when we fitted the new ones.
Thats not to say every one of these engines with the same mileage as this one will need injectors.
This car had a slightly rough idle in open loop, not a misfire.
After the usual plugs, wires, filters and so on he pulled the injectors.

As he found out later drivability was indeed effected more than he thought. The engine had more power and better acceleration as well as a smooth idle in open and closed loop.
These injectors are a well know sore point. Not that its an inherently bad injector, it isn't but they don't handle ethanol well.
 
Ok...The old injectors were so bad they needed replacement at 92k. The new injectors were still like new at 40k using Si-1. It works! Protected them too.
 
Yep it works good. I recommend it highly to all my customers.
I don't sell it or even offer it but i have faith in this product.

You have probably already seen this but if not its worth a look.
The injector parts look like the ones in the picture at 1oz per 10 gal on new units after 40k. Units that have been cleaned should provide the same results.

o how many gallons does the 1 bottle(15oz) redline s1 treat?

150 gallons.
I get mine from Amazon with free shipping, its not a bad deal.

If you have not cleaned the injectors use a full bottle the first time with a full tank of gas.
The less you drive it and the longer it takes to burn through the tank the better within reason of course.

The longer it can sit in the injector working the better.
If it takes a week to go through the tank that fine.

After that just 1oz per 10 gallons will do it.
 
@Trav thanks! wow 1oz = 10gallons... so basically i only need 2 oz for a 20gallon car! that's a pretty strong additive

How often do you use the redline s1 cleaner? I've been using fuel injector cleaner lately.. so maybe i won't need to use th whole bottle! haha

Thanks for the replies!

That 1oz per 10 gallon dosing is the maintenance dose.

You can get that maintenance dose by using Chevron gas.
 
I thought the Redline maintenance dose was 1.5 oz per 10 gallons. Thats the amount I've been using for some time.
 
Well Trav said it so he must be right. It's probably what they do in Germany.

Redline must have some underhand reason for giving you that information, maybe to restrict your choice in America.
 
Your right it does say that i must be using too little. Thanks for pointing that out.

I have been going by the lines on the bottle, i thought it was 1oz increments. So i ws using 2oz instead of 3 and it still worked fine but follow the directions.

I use it every time i fill. I don't drive my cars much and when its short distances. Deposits on the intake valve and in the injector are an issue.
If you use the car daily you can do it that way or a bottle every 3K or so.

Try a single cap full in small engines like lawnmowers and snowblowers when you tank them. The carbs stay nice and clean although it doesn't replace Sta-Bil.
 
Well. Happy join this topic since i'm recently searching about fuel system cleaners and would like to start trying some.

For my experiences, I put a whole bottle of Redline in my 15 gallons tank once. Then I did a 700 miles road trip, mostly hwy of course. But I didn't really notice any improvement on my car after that. I'm sure the injectors shouldn't be very healthy since the car is driven under severe condition. I know RL is proven to be great. Maybe I just didn't leave it in tank for enough time?? Maybe

Now, I decided to try either Techron or BG 44K for my next treatment, prefer BG a little more. It used by many dealers including mine. Some say they're the same stuff but BG just stronger...

Any idea about these two cleaners? Thanks in advance.

Honestly, in the old days Redline fuel treatment never worked for me. I do think the one these guys are talking about is a newer formula.

You also might want to give Amsoil PI a try.

Maybe thats why the slight under dose works for me as well as it does. It takes me about 3-4 weeks to use a tank of gas in each of the cars.
PEA needs some time to work in the injectors, putting it in the tank before a road trip will give you the least results.

BG and Amsoil PI are both good but need time to work like anything else if your trying to clean not just maintain them.
