Yes the days of 2 for $10 are behind us but $8.99 isn't bad going off the past couple of years of pricing.
Was skeptical at first but chucked it in my 275,000k Sportage to see what it would do and my mileage went from 8.5L/100k's to 7.9L/100k's and got rid of a pesky rattle whilst being more responsive. Results would vary, but seems to work well for high mileage cars as it has PEA - the good stuff.
Each to their own though, i'm a convert.
Wondering too
A noticeable difference when I was driving a 2005 Jazz, but people were telling me it’s snack oil.
snack oil.
Do not cook with this.
A Jazz Vibe?
snape oil!
@Drakesy How old is the 275k Sportage?
About 13 years
I'm just curious — "went from 8.5L/100km to 7.9L/100km" — was that result from the first tank with the additive, or has it been consistent over multiple tanks, even after finishing the one with the additive?
@nashB: Clean injectors work better than dirty ones, that's for sure. But the actual variables in a home grown economy test are infinite. Be more concerned about the things you can quantify using it.
@nashB: Yeah it was consistent for about 6 months of driving after not just 1 tank. Driving style didn't change (largely city) mind you thats probably why it was so gunked up with the stop start driving.
I have a 2007 corolla with 98k KMs and I have used many types of injector cleaners ( this one, liquimoly, lucus). The injector cleaners make my engine quieter Like really quiet, at idle I don't even feel the engine running. After a few thousand KMs the effect is gone. I haven't noticed any performance improvements.
why would they need to when this bottle is $9
thanks, bought 2
I used the diesel one on my outlander. It appeared to work.
Will this work on a carbureted engine with a manual choke, and is it also safe for a sophisticated and actually reliable Japanese V6 with both direct and port injection, @SYLTB Covering both ends here, one that goes anywhere, and one that gets there fast (without breaking down).
German powered cars don't require such a product due to advanced engineering.
You meant to say German cars won't survive that long so not relevant anyways? Advanced engineering my a**. Lol
Was about to say just this
Exactly. As @SYLTB will tell you, German cars don’t need injector cleaner, they skip straight to injector replacement. That’s real innovation right there.
Never heard of Rislone until that "Garbage Time" episode on YouTube 1-2 weeks ago, and now there's a deal for it, coincidence?!
Its a big brand in America. It's not bad. It's literally coincidence…
Frequency Illusion
My 80-year-old retired mechanic says, "Don't wake the dead" on the topic of old engines and additives/flushes/cleaners…
He's telling you to f-off and leave him alone
😆
Was this after or before the service?
Awesome deal. Thanks.
I have used it and it works like a charm.
https://www.bunnings.com.au/nulon-150ml-petrol-injector-clea…
I've used Rislone before and it seemed good. Nulon from Bunnings is currently a bit cheaper as an alternative if wishing to save a few dollars.
No PEA which is the good stuff
I like these bottles for other additives I use like fuel dr or diesel power.
Much more convenient to add to the tank while I'm at the servo.
Thanks….got 2 for my diesel
This worked well for me in the past. Not a bad price. AFAIK this contains Pea (and should even say so on the label)
Thanks OP.
I've tried a couple bottles (spaced out as per the requirements), but didn't not any differences.
Will try this one and see how it goes.
Aren't these things snake oil for cars?
who would have thought snake oil would clean injectors when burning
Maybe. Hard to say. It depends what sort of compounds you have lurking in your fuel system.
But it's unlikely to clear away any major buildup. I wouldn't bother with it. If you think your fuel injectors are clogged, then get some carb cleaner and do this
But then I need to buy carby cleaner… a vice… a 9 volt battery and a tire valve and take my injectors out of my car (and actually know what I’m doing) and go to a junk yard and cut the wiring loom.
Vs $8.99 DIY liquid gold that might not do anything for my car - I know which one I’m doing (rolls the dice)
The short answer, no. So long as they contain the polyetheramine (P.E.A.) detergent, they will work for most.
A good explanation from The Motor Oil Geek here, skip to the 9:40 mark to see the fuel additive section.

Yes but sometimes you need snake oil.
Use this and fill tank with 98 RON fuel and thank me later
pump e10 does the cleaning
Go to Caltex while your at it. Techron does wonders.
Not if you have a diesel engine
They should have a water separator
Any specific locations 🤣
might try this in my bmw
Might work, might not. For $9 it’s probably worth it.
I’ve used a few different types in the past, they often say don’t use more than once or twice between oil changes (just a heads up).
Separately did notice some octane boost as well (different brand from this) so likely does something
AI verdict:
The short answer
Yes, Rislone’s injector-cleaner range can dissolve and flush light-to-moderate carbon or gum deposits in both petrol and diesel injectors, because the products are built around a proven detergent—poly-ether-amine (PEA).
No, they’re not miracle potions. Gains in smoothness, fuel economy or power are usually small (often 1–3 %) and you will not rescue an injector that is already mechanically damaged or almost totally blocked.
Bottom line
Not snake oil—there is solid lab chemistry and field data behind PEA-based injector cleaners, and Rislone’s SDS & marketing confirm it uses PEA.
Effect size is modest. Think of it as maintenance (like running a fuel with extra detergent) rather than an engine overhaul in a bottle.
Choose the right tool. If your problem is a nearly blocked injector, burnt pintle or a soot-packed DPF, no pour-in additive will save you—mechanical cleaning or parts replacement is the fix.
If you’re seeing early signs of injector fouling, or you don’t always have access to Top Tier petrol/diesel, a bottle of Rislone every few months is a cheap, chemistry-sound precaution.
I just use Lucasoil fuel treatment as a preventative strategy. (On all petrol & diesel engines.) We buy the ~4L sized bottle and decant to smaller dose bottles to carry in the vehcles.
AI summaries: inaccurate at best.
should i do this before or after an oil change?
doesnt matter.
Another thing to think about, I'd run this just prior to an oil change. There's been some reports (and studies) related to thickening of oil when using PEA.
The TDS doesn't say how much PEA is in this one so it's hard to say how much of an impact it'll make, but to be safe, use it when you know your oil will be drained shortly afterwards.
But you put this into your fuel tank…
If your engine is somehow putting fuel into your engine oil, then something is very wrong. The two things shouldn't be mixing !
Look up fuel/oil dilution. Very small amounts of fuel can/do get into your crankcase - depending on engine age and tolerances, driving habits, (lack of) maintenance etc.

Sludge and Varnish Evaluation of Polyether Amine Gasoline Fuel Additives at “Complete Fuel System Cleaner” Aftermarket Fuel Additive Concentrations 2020-01-2100
Sludge and Varnish deposits that can build up in the crankcase originate in large part from fuel and fuel components that enter the crankcase through blow-by. These deposits can lead to a variety of engine issues including piston skirt deposits, cylinder bore scuffing, stuck lifters and oil filter plugging. A test has been developed to evaluate the contribution of “Complete Fuel System Cleaner” (CFSC) aftermarket fuel additives to crankcase sludge and varnish deposit formation. CFSC aftermarket fuel additives are typically formulated with polyether amine (PEA) chemistry and at concentrations that exceed 2000ppm. Three different commercially-available CFSC products were tested, containing two different classes of PEA chemistry - propylene oxide-based PEA (“PO-PEA”) and butylene oxide-based PEA (“BO-PEA”). Two of the three products contained the same PO-PEA chemistry, but at different concentrations, to show the effect of additive dosage. Using the Sequence VG sludge and varnish test rating criteria, it has been shown that PO-PEA can lead to a borderline failing result for varnish formation at the lower treat rate, and an extreme failing result at the higher treat rate. BO-PEA chemistry did not lead to noticeable varnish formation. All three of the tested additives yielded passing sludge formation results, though a slight degradation in sludge control was observed with PO-PEA at the higher concentration. Analysis of the used test oil demonstrated that the BO-PEA chemistry led to a 73% improvement in oxidative stability, when compared to used oil from PO-PEA testing. It is hypothesized that the lower solubility of PO-PEA can contribute to the formation of sludge and varnish precursors that have the potential to cause significant engine harm.
How much do I need for my EV?
Use the same amount as you use in your headlight fluid bottle.
No gloves are needed to top up your battery acid.
To access the battery acid in your EV, you need to drill into one of the lithium ion cells and lightly add distilled water (distilled water is important) once there, you just need to fill the hole with lead. Again, no need for gloves.
Change your blinker oil first.
Is this ok to sit in a tank for an extended period of time (ie. a car that is not driven often)? Or should it be consumed soon?
I find your use of the word "Consumed" in the context of what you wrote to be both intriguing and alarming
All this stuff is BS. Don't bother buying. Never proven to do anything.
Want to clean your injectors? Get them pulled out and ultrasonically cleaned.
What is PEA?
Polyetheramine. PEA is a chemical compound class that is used in fuel as an additive. Polyetheramines are known for their good cleaning performance in the event of deposits in the combustion chamber and on the outside of the injectors.
Thanks.
The green stuff next to the CARROT
detergent with a fancy name, aka snake oil.
It comes out of most urethra’s, however this has been misspelled in this instance.
with PEA is real stuff otherwise is snake oil.
Pretty much this. I use a redline brand additive that is 30% PEA in my 320km AMG V8. The trouble is a lot of additives don't list exactly how much PEA is in them, just that it has it.
Its not going to make a noticeable difference just from driving, most people who claim "this and that" are experiencing the placebo effect (especially on a DI engine lol).
But there are SAE research papers that prove PEA additives remove built-up carbon from the injector, intake and inlet valve. But PEA also deposits more carbon inside the combustion chamber (which no additive will remove without doing the same thing) vs straight petrol.It is weird to get your head around. So to be clear, PEA does remove excessive built-up carbon from the chamber, but it also leaves a certain amount of its own carbon residue behind. Its like a cost of doing business.
Upshot is if you have a new engine, don't use it because its a double edged sword. You already have clean inlet/valves/injectors so you will just be adding extra carbon deposits (vs straight petrol) to your clean combustion chamber for no reason. But a well used engine will benefit from it since there is usually a lot more built-up carbon in the intake than in the chamber, so it has a positive overall effect.
Nice summary stumo.
PO-PEA - propylene oxide-based PEA - is the one to avoid. Looking at product SDS's might reveal which variant is used for regular users of additives : https://www.ozbargain.com.au/comment/16676045/redir
Positive experience and definitely give this a thumbs up. Using this product made a considerable improvement to driveability by removing the rough idle and providing better fuel economy. 2013 Peugeot 508 1.6 THP petrol with direct injection and 174k kms. Always use BP 98. Have had the valves clean.
Used three bottles so far over a five tanks of fuel over the last five weeks. Used two bottles back to back and the third on the 5th tank. Outstanding result.
lol overkill?? is there a limit?
Some say it's not so good for your engine oil, so probably best to use caution. 1 bottle in the middle of the OCI shouldnt harm anything, but 2-3 bottles just before an engine oil would be ideal.
I agree, and yes it is due for an oil change and considered this when I used the cleaner.
Not overkill for me as it rectified the running and driving experience. I'm not aware of limits, but I used what I thought necessary at the time. I've tried other products in the past and found this one to be the most beneficial. I may not be an artist but I know what I like. YMMV.
Doesn't say much for BP's 98 cleaning agents - present in most 'premium' fuels. A lot of short runs in the Peugot presumablyTangles?
Yes, short runs to and from work 10-15 mins each way.
Can I put this in my washer fluid to boost clarity?
These are P.E.A based, so are one of the very few that are not snake oil.
Doh! I got a bottle on the weekend, on special, $18!
k
Lol 😂
Bought a bunch of bottles- 1 for each car for the extended family.
The dilution rate would differ from car to car based on the fuel tank size, so you would have a varying concentration of PEAs per car. The PEAness of my 75L tank would thus be much smaller than the PEAness of a smaller car with a 45L tank for example. Im a bit worried about my small PEAness, but my wife says she loves me regardless of my PEAness.
I asked a friend about PEAs and he ridiculed me. I think he has PEAness envy.
brilliant!
Reported.
Bought penrite from Amazon
Awkward clap moment? 🤔
@pegaxs do these really work?
