    Poured one in my 2017 Renault Koleos before and it improved the fuel efficiency from 10L/100km to 8.5L/100km. Howver it only last for about 1 months then it's back to normal

    •  

      I usually fill 1 x u98 every 4 x u91 fills and this gives me extra 100km+ mileage from when before I started this routine

        I bought 7 bottles and each time it dropped by 1.5L/100km. In the end I was making fuel.

    Injector cleaner additives are a scam. They do nothing. To clean injectors you need to remove them from the engine, not just pour some kerosene in the fuel tank.

    Success stories are always anecdotal with no scientific method behind them.

    • +6 votes

      Well if I can provide an anecdotal, my Jazz started to stuttering, after having a chat with ozbargains pre-eminent mechanic, I decided to try the easiest option suggested with was to pour some engine injector cleaner To see if it made a difference. Clearly, my car needs the injector cleaned, because after pouring this stuff in( in this exact brand actually) the stutter went away. But after two tanks it comes back and again I poured the second half ( this is 300ml and instructions is to use half bottle per tank). And again it helped with the stutter.

      So clearly this helps, to say it does nothing is incorrect, but it certainly doesn’t fix the issue.

        I used it on 2.4L hyundai i45 and what I felt was the car improved in acceleration and has more power to pick up in speed when complete stop at the red light… however it does nothing to fuel consumption saving, it only saves fuel depends on your driving style.

        For an old car (with high mileage), you still need to manually remove the injector and clean it instead of relying on this so-called injector cleaner liquid however it will perform just fine for low mileage car that would like to keep the car remains consistent.

      •  

        You actually get the benefit of being able to drive your vehicle with 2 tanks of petrol, tho .

        The point being if you believe fuel additives can clean, or improve, your engine to make it perform better (and use 98 octane for your specific vehicle) then you could opt for BP Ultimate on your next 2 full tank equivalent fill ups for a comparable perceived benefit.

        • +1 vote

          Sad that BP ultimate is more than $10 for 2 tanks of petorl compare to 7-11 or Coles or Caltex in my area.

          So I would pay $3 instead of 2 full tanks around 90 litres of petorl.

    Ran a whole bottle in my CBR 125R(98 Octane) last time they went on sale, no noticeable difference in L/100 (2.5L-3L) or Power and trust me you would notice if you gained power on a 125cc.

    •  

      it doesn't work on a bike or car that has smooth injector (like new car/bike) if pour this thing and does nothing.

      Unless you felt your vehicle has loose in power or doesn't perform as how it used to be probably may try however not guaranty it would do anything.
      If your injector is too dirty better of disassemble it and clean it manually. But for sure won't save fuel, it totally depends on driving style.

        No it will no at all. The carbon is on the back of the intake valves because no fuel cleans them, driving higher in the rpm range doesn't magically make fuel come from somewhere else

        •  

          Depends. My Skoda have both port and direct fuel injectors. Not sure when which is working but should help with the carbon buildup issue.

          •  

            @Safoan: No, it doesn't depend. In straight direct injected cars, which is what was mentioned, no fuel gets to the intake tract or back of the valves.

          So do many lower octane fuels.
          Eg: Shell Unleaded 91 petrol meets the requirements of the Australian Fuels Quality Standards
          Act 2000. Shell Unleaded 91 petrol has a minimum Research Octane Number of 91.
          Shell Unleaded Petrol contains Shell's exclusive Fuel Economy Formula, which is designed to
          protect the engine from the build up of harmful deposits. This helps improve performance by
          keeping clean fuel injectors, carburettors and inlet valves, which helps lead to consistently
          good gasoline/air mixture preparation, better combustion, better driveability, better fuel
          economy and reduced maintenance.

    Ethanol is a superior fuel additive to lead, preventing engine knocking and providing additional energy for combustion with no toxic combustion by-products.

    Despite this, the automobile sector decided to use lead, a known poison that appears to have caused the violent crime statistics that plagued the 20th century as well as causing measurable, permanent IQ loss in the population.

    Lead is still added to fuels in many third world countries.

    The reason lead was chosen? Anyone can make ethanol meaning they would take less profit.

    •  

      Lead is also a valve seat lubricant, it may have been important back in the day. Plus lead is cheap, they didn’t know (or care) about the dangers then.

      So you're spending more on top end fuel when you don't need it but you won't buy this? Okay.

      •  

        He may have meant top end fuel brands which have their own proprietary cleaners which make products like these relatively redundant. Irrespective, plenty of modern vehicles "need"/run more efficiently on higher RON fuel.

      •  

        Who doesn't need premium fuel?

        •  

          Anyone with a low performance, low compression engine. Higher octane is primarily used to avoid knocking or detonation inside combustion chamber. That is, the mixture igniting before the spark plug goes off.
          Higher octane does not provide more power, in fact it is less volatile than lower octane.

          However, some high octane fuels have cleaners and detergents that supposedly clean the fuel system.

          I've tried a few fuel treatments and the fuel doctor seems to work best. No substitute for actually getting injectors cleaned though.

          •  

            @9839002:

            Higher octane does not provide more power

            It does, in general. Many (most?) modern engines advance timing for higher octane fuel based on knock response, thereby providing more power (see the videos below to understand how/why). Many people (and some tests) also claim an actual (on average) decrease in fuel consumption when using higher RON fuel, however the increased cost of premium fuels (98 esp) more than offsets that small gain.

            Same bloke also discusses fuel additives elsewhere

            •  

              @Possumbly: Then that's the advanced timing that is providing more power. Not the fuel.

              •  

                @9839002: Okay. I suggest you watch the videos in the links and learn why your comment is basically incorrect for many modern engines.

                •  

                  @Possumbly: I quote Wikipedia

                  The other rarely-discussed reality with high-octane fuels associated with "high performance" is that as octane increases, the specific gravity and energy content of the fuel per unit of weight are reduced. The net result is that to make a given amount of power, more high-octane fuel must be burned in the engine. Lighter and "thinner" fuel also has a lower specific heat, so the practice of running an engine "rich" to use excess fuel to aid in cooling requires richer and richer mixtures as octane increases.

                  •  

                    @9839002: Quote whatever you like. Alternatively you could read credible commentary and look at test results such as those in the engineering links I provided. There are myriad motherhood statements on the net which aren't up-to-date, don't understand the concept of engine tuning for performance, and/or have minimal appreciation of the technology of many modern car engines - which are able to measure knock and adjust timing, thus taking advantage of higher RON/MON fuel (and its lower relative volatility or in other words, increased resistance to pre-ignition) to make more power and torque. Not all engines and ECUs are smart enough to take advantage - as the Jeep seems to demonstrate in the fuel test graphs in the videos.

                    Here's a simpler commentary which also mentions the role of carbon bonding in fuel : https://www.carsales.com.au/editorial/details/myth-busting-h...

                  •  

                    @9839002: Btw that last link validates, to an extent, your original comment - except for the fact that the higher RON fuel we use is refined so that it actually has, according to him, more C-C bonds. Ergo should have (supposedly) more energy as well as less ping. The tests in the engineering video running two cylinders on premium and two on regular fuel, then swapping over are eye opening (https://www.youtube.com/watch?v=gqvhaPLuTPI), even if you don't believe the bench tests/graphs in this one: https://www.youtube.com/watch?v=dxAQmj3P8xs

    Most of the major brands have additives in their petrol which do a similar job but an occasional squirt of these types of products in your tank won't do any harm.

    Removing lead from the environment is kicking a goal for Mother Nature, it's not the best for my diesel engine though. I've been using this as an additive to improve lubricity, I use it every second tank.

      Maybe get your injectors professionally cleaned. They remove them and use ultrasonic energy. If you can remove them yourself, some places allow you to bring them in or mail them in.

    People still buy this rubbish and think it works?

    These used to be in before 98 Octane Fuel was widely available, think about the 90s and above.

    If you have an older model car that uses Unleaded, just use 98 Octane every now and then. 98 fuel is less likely to be wasted in uncontrolled combustion which may give more mileage (results vary based on engine condition)

    •  

      So does that means 91 + this =98? Or you are saying 98 is way better and worth 13-18 cents more a litre?

        98 Octane is doing the same thing and at ~$1.40-1.60/L

        • +1 vote

          One bottle $3 putting on top of 1 tank(60L) and 91 = 98 .
          1 tank of 98 is $9-12 more expensive than 91 so you are saving at least $6.

          My question is should Nylon + 91 = 98? If so you are saving to by using Nylon when it the price is low

  •  

    Ahhh just got two

  •  

    I have a very small 1.25L Kia Picanto. Sometimes I run 98 through it. Does anyone think running such a small engine and tank (30L) on 98 is worth it? It’s only a few dollars more typically. Would a product like this be of benefit in any way? Excuse my ignorance but thanks in advance!

    •  

      Unless the car was tuned to use 98 (check the manual) then you are just literally wasting money.

    •  

      Small improvements in power and fuel consumption (lower) are possible with higher octane fuels in many modern engines, not sure about yours though. The huge price differential (91 to 98) suggests you're probably throwing money away though.
