In this video I show Before - After of using Liqui Moly Gasoline System Cleaner to fix Rough Idle and low miles per gallon (mpg) issue in my Honda Accord.

WHY I USED FUEL SYSTEM CLEANER?
At about 130,000 miles my Honda Accord started having rough idle issue and mpg also dropped. I used Liqui Moly Pro-Line Gasoline System Cleaner 500 ml to see if that makes any improvement. The video shows the situation before, and after I cycled through two tanks of gas (about 900 miles of driving).
WHY LIQUI MOLY?
In past I have used many fuel additive cleaners, fuel system cleaners, and fuel injector cleaner with varying results. Some of the popular ones are:
* Chevron Techron fuel system cleaner
* STP fuel injector cleaner
* Gumout fuel injector cleaner
* Lucas fuel system cleaner
Mostly I do this to get best fuel economy. This time I had a rough iddle issue and wanted to try something new so I used 'Liqui Moly Pro Line Gasoline System Cleaner' which was only available at Napa store or online.

good result. At first I thought the symptoms point to a MAF sensor needing cleaning/replacement but may try this. My CRV runs on LPG but the initial starting on Petrol has these symptons so will combine MAP and Gas cleaner and hope.

[@FlyBeee]

If you tried this, what are the results?

[@ddsupplyco]

If you like Liqui Moly the Di-Jectron seems really interesting. But I use Gasoline Extreme by Hotshot Secrets in my Accord. Only at 42k though haha. Maybe needs new spark plugs/ignition coils?

[@FlyBeee]

Thanks for detailed feedback. I will look into Di-Jectron! Best wishs

[@kadenawarlord2700]

I usually pour roughly half of it in first, then fill it up, n then pour the second half in when i go and fill it up again

[@FlyBeee]

My understanding is that a certain concentration of the cleaner vs quantity of gas/fuel has to be present for it to work. The back of the bottle lists the detail. How much we use depends on the vehicle. The Honda Accord has a 17 gallon tank of gas for which full bottle of Liqui Moly was needed so I poured the full bottle in. A different quantity will be needed if using a different vehicle and/or different size of Liqui Moly.

[@kadenawarlord2700]

@FlyBeee theres only three different fuel types where im from, 91 is the standard, premium 95 & 98. Supposedly you can clean your fuel systems, by putting 95-98 in, due to the additives, though it isnt as efficient as liqui molly From my understanding in the states, there are way more different types of petroleum you can put in your car, sub 90 isn't supposed to be ideal but affordable to many?

[@asusb7577]

Does this cause clouds of white smoke to come out of the exhaust like the seafoam product?

[@FlyBeee]

no this does not cause cloud of white smoke from exhaust.

[@ciegosanchez5289]

Is this the same product as sea foam or is it better?

[@FlyBeee]

This is different from Seaform

[@3RunnaWRLD-fp4xr]

Better and newer formula... Seafoam is outdated

[@Calonv]

Do you know if this works on GDI engines?

[@FlyBeee]

I do not know, I only tried on my Honda vehicles you see in videos here.

[@theminicooper]

Any product would work in a GDI engine. The only downside to a GDI is that no gas additive will clean the intake valve since gas is injected after the valve, not before the valve like in port injected engines. There are other products available to clean the intake valves on GDI engines however, it's a more involved job. Also, video states this is a 2013 Honda Accord and this model year has Direct Injection.

Thank you and best wishes! 🙂

[@dodok961]

Do I have to add it then add new gas ?

[@FlyBeee]

Either option works, it mixes with the (new) gas in the tank which is what we want. If you have half a tank of gas, take your vehicle to gas station, add this in tank in and immediately fill the tank to full.

[@lockey319]

Fill with gas first you don’t want your car running off of that as main fluid

[@jamiedriscoll9781]

​@@lockey319put the cleaner in an empty tank at the pump then fill up. Adding the fuel second will make sure the product is mixed.

When i used this i noticed my car got better throttle response on the gas pedal, also better fuel economy as you noticed too. Also Fifth Gear did a test on a Volkswagen Corrado to restore power with pour in cleaners and other methods. The "Red-X" got 6 hp back from the grave, dyno tested, video is on KZbin. For the Nay-sayers, calling this Liqui Moly snake oil, it is like 15 bucks for something that works well, try it before you judge. (Me former Nay-sayer) Edit: Name of Fifth Gear clip " Can You Restore Lost Power To An Old Engine? TBT - Fifth Gear "

[@FlyBeee]

Liqui Moly definitely works! Thanks for the suggestion about Fifth Gear video, I will check it out.

Do u hv same problem with me ? after I start my car drive little while then it’s kinda shaking . Then it’s gone ... but it happen every couple days ...

[@FlyBeee]

A few things can cause shaking. I had rough idle issue when car was standing still and this fixed the issue. Does shaking in your vehicle happen when it is moving or when standing still?

[@dodok961]

@@FlyBeee when I pause my brake

[@FlyBeee]

@@dodok961 This may be an easy fix! All my vehicles developed vibration / shaking at one time and worst was in my Honda Odyssey minivan. The issue was caused by warped brake rotors (discs). I replaced the brake rotors with good quality rotors and it fixed the issue perfectly. Have you looked into this? If interested, see my video on this here and also review the narrative/description: kzbin.info/www/bejne/eYHMgnpneLRgea8
