I tested Liqui Moly on Piston Carbon Removal: Liqui Moly Valve Clean Works on Piston Carbon Build up
ฝัง
- เผยแพร่เมื่อ 11 มิ.ย. 2024
- I tested liqui moly over a month for piston carbon removal and can say that Liqui Moly valve clean works for piston carbon build up cleaning. To clean carbon without disassembly, especially for piston carbon cleaning, one has to resort to the use of fuel system cleaners or fuel additives. Not all cleaners work for carbon buildup removal as advertised, but I've definitely found how to clean carbon buildup in the combustion chamber. If you are asking "does Liqui Moly work?" Liqui Moly valve clean really works, and I think I now have the perfect formula after I tested Liqui Moly for a month with every fill up.

What do you think? 🤔 Willing to go several fill ups in other to get clean pistons? I guess significant buildup will require multiple treatments.

What are the side effects of having the carbon deposits, go through your cat. Does it burn off in the cat?
From a previous video I did, it will burn off and not get trapped in the CAT.
It will break down your engine due too a thick layers of carbon over piston@@davidkrocks
Heard you can remove carbon built up using paint thinner by put it inside the petrol tank with 1/2 tank of fuel.
@Imran-fc2qh Heard that too but don't yet have the stomach to try that 😃
PERFECT video, fast but not too fast, no nonsense and acheivable and consistent testing. Great job.
Thank you very much!
I agree. Perfect video. No nonsense and perfect pace.
Thanks!
Very nicely done! It’s uncommon to see a review that uses a product consistently before passing a judgement!
Thanks for watching and your kind comment!
No bla bla . We need all mechanic videos to be like this .
nice clean video straight to the point and no endless nonsense talking. thank you
Thanks. 😀
I agree This Guy's vids are everything we need to know and not filled with nonsense babbling. ❤🎉🎉🎉
This man torques the plastic cover bolts, he plays by ALL the rules.
Yep.
It's possible some of the issues at Boeing today; particularly the door that blew out during a flight had the technician using his trusty, non-caliberated human torque wrench👀
This is a top notch video. The before and after is truly impressive.
Thanks for taking the time to comment. Appreciated!
The kind of video we want. Straight to the point!
😃🙏🏼
FINALLY! Thank you for showing us the before and after pictures of the cylinders. That’s the confirmation it really works. Every other other review I saw just talked about their experience but no one looked into the motor where the cleaning happens. And thank you for not giving up after one bottle. 👍🏻👍🏻 Would be nice to see pictures of the valves and spark plugs too.
It would also be interesting to see what difference the premium gas of Aral or Shell with their additives are doing to the cylinders and how normal gas has an impact.
Hey, thanks a lot for the compliment!
Regarding the valves, the car is GDI so I won't expect any cleaning there. I agree; if I had Shell V-power, would have done a similar experiment with it vs regular gas. Thanks again!
After 6 cans it really works wow nice video
I know right. Thanks!
That is a surprisingly thorough testprocedure! Very nice, good pacing and very good method of procedure. The brown residue which is most likely from subpar fuel with excess sulfates etc. won't be burnt away with Liqui Moly. Only with high quality fuel you get a chance. That being said, this residue is neglectable and only carbon buildup is of real concern. Well done!
Thanks for commenting! True talk on the residue. Still concerned about it as it will affect compression ratio if it continues to build.
I had some issues with my Kymco AK 550. I found your video and it helps me to find the correct cleaner for the injectors. I want to thank you for your video and your work. That's a great job!
Glad it helped. If you're looking to clean injectors specifically, they have the Liqui Moly Jectron which is for cars with MPI and the DIjectron for cars with GDI. I used this Valve Clean because the others were unavailable and my target was the combustion chamber.
What a comparison and so much evidence that it makes understanding the process clear. Thank you
Thanks a lot!
Perfect in-cylinder camera. Nice shots. Thank you man. So it wan't help much in one take, but definitely helps within a two-three takes.
Exactly. I reckon if you have like a 300-mile and above trip, it won't take as much.
One of the best before and after videos!! Excellent job, you made me go try this.
Thanks!
This was an excellent video. I especially liked you explaining on opening the car up on those longer trips. Well done!!
Glad you enjoyed it! Thanks!
Hi, today is Aug 28/ 2023, @ 1:51AM.monday.
I've been using Liquid Moli for over a year and a half. Gas and oil treatment. I have a 2004 Nissan Maxima 3.5 V6.
It was emitting blue smoke ( burning oil) on start up. Well a friend suggested that I use this treatment to see if it helped.
Well, good news! It did and it continues to do so!!
No more smoke, the tops of the cylinders are very clean. And the exhaust pipes don't have that black soot. They look new.
The cars runs great.
I changed out the electronic coils, plugs and installed a new plenum gasket...was leaking a little blow by. Engine is very tight! The stuff is great!
By the way? Great video!
Liqui- Moli is a great product!
All
Wow! Thanks for taking the time to write such detailed feedback. I think so too about Liqui Moly products.
I used their engine flush plus and it really did decent work on a sludged up engine.
Thanks for the compliments too!
Absolutely BRILLIANT video! Perfectly fortmatted and good coverage and comparisons! Subscribed for sure
Thanks!
@@DIYAutoworksNGmay i also ask Why The Clean Gas Step without liqui molly whats the benefit?
Nothing really. Just wanted the product totally clear of the system, plus have a sense of its ability to prevent buildup coming back.
@@DIYAutoworksNG thank you so much for replying to all my comments plus Your Videos Are very Helpful and The Comparisons you do with the Products and how effective they are provides People With Fresh perspective about Additives whether they are trash or not Hope you keep making them👍🏻
Thanks!
This is the kind of stuff I want to hear and apply to my Corolla !
I was not sure about this product, but watching your video, i'll give It a try. Simple and straightforward video. Well done and thank you !
You got yourself a new subscriber.
Thanks for the kind comments. Also for subscribing. You're most welcome.
Finally another video on point. You are my personal online technician, and as a Nigerian you make me give my local mechanics a hard time at their job trying to deceive me😂.
Liquimoly has always been the best on the market for me so I wasn’t surprised.
Thanks mate.
Ps. I lost my cars keyless entry device so I only have the key left, do u have a video on how to configure a new one. I’d appreciate leaving a link for me.
Thanks 🙏
😂 on your first paragraph.
What car is it? Did you say you lost the fob part of the smart key while keeping the blade? Or that you now have only 1 fully functional smart fob?
@@DIYAutoworksNG Honda Accord 7th gen, I do not have any key fob currently only the conventional key 🔑.
Easy program another key using your existing one. I don't have a video on it personally, but there should be a lot on TH-cam. Can also be done using many scanners.
Great video. Thank you for putting the time and mileage into the project. Liqui Moly is in my opinion the best overall to always use as quality of fuel slowly gets worse. You might want to swap your plugs, valve clean can leave a strange byproduct on them. Fresh plugs will always help everything work the way it should during cleaning.
Thanks mate!
I didn't really observe any out of the ordinary deposits on the spark plugs.
You know you can also clean plugs? My dad used to do it on his cars when I was a child (loved 'helping' him work on the car at weekends). He had a soft wire bristle brush just for the job, would whip out the plugs, clean off the junk (leaded fuel back then and clearly not as squeaky clean as people like to think) and then check the gap (and reset as needed) with a feeler gauge. Really simple job anyone can do. Seems wasteful to bin plugs just because they look dirty. They last a long time really (my grandad was involved in the manufacture of NGK plugs).
Put a scope on them. A scope will pick up any additive. @@DIYAutoworksNG
Right now I am on vacation and because I will drive the car for about 600km I decided to dump a bottle of Benzin Additive from Liqui Moly to a full tank with the hope it will clean some carbon deposit. First option was Performance Improver from Amsoil but was a little expensive and second option remaind from Liqui Moly. I hope to see some results but based on your success I will surely use the Valve cleaner product for the next fill-ups. Thanks for the invested time in searching products that worth buying.
Thanks mate. I'm sure 600km of straight driving will do a lot of cleaning. Getting and keeping the combustion chamber hot with such a cleaner is the perfect recipe for cleaning carbon.
Brilliantly done video! Always thought this sort of liquid was snake oil but after watching your video I'm going to give it a try, thanks
Thanks
I was very fortunately suggested by TH-cam. Excellent video. I hope to see many more!
Great. Happy to connect!
Impressive video and results. Clean pistons improve compression and performance. Its quite difficult to clean them and most products have minimal effect. I use several liquimoly products and i'm also going to try this one.
Thanks, mate. Really nice product. I'm sure if one has a 300 - 500mile trip straight, it'll cut the carbon much quicker!
@@DIYAutoworksNG i love your vids: short but clear, straight to the point without nonsense! Keep it up! I own a BMW E65 730i N52 in great condition with 250K km. Greets from the Netherlands!
Thanks, mate. I just enjoy making and sharing these videos!
It works great. It also is a great presoak on pistons and heads if you're cleaning up carbon. Overnight and it flakes off and cleans right up.
Good to know. Never tried using it as a a presoak.
Would've loved to see the valves too but all in all, very well demonstrated. I'm impressed with it and giving it a shot for the next 5 tanks of fuel.👍
The valves should show some reult if it's multiport injection, however, this car is GDI, so I wouldn't have cleaned the vakves
holy smokes! that's quite a remarkable improvement, it can't get more definitive than that! thanks for the thorough attention to detail, awesome video.
Thanks so much!
I love using all of Liqui Moly’s products!
They are becoming my go-to too!
be nice to pair this with an oil catch can, and of course an oil change not too long after application. great vid!
Right on the money! I have an oil catch can already installed. Did so early this year. Has significantly cut deposits reforming since installed.
Best video and explanation for the product. Liqui moly should hire you bro 👍🏽
🤣 Thanks for watching!
No annoying hands and music, ty.
I hate those too. Lol
I have subscribed to your channel. Very well presented and informative
Thank you!
To think that I just started researching about Ceratec and I saw your notification 😂
😁 Haven't used ceratec before, but I've heard good things about it.
Great determination on your behalf!
Great video. Thankyou. Used liquid moly in my Subaru Legacy 3lt. Will now give it a go in my wifes' little Auris
Smooth. 👌🏼
I would love another test with a MPFI car, as these being an older techology found in older cars, deposits MAY be even more substantial/
Great Vid .
Thanks mate. On the contrary, GDI would have more buildup all things being equal.
Clearly a cleaning method for the patient minded.
Yea. Well, if you have significant build up like I did, you'll have to be patient except you want to pull the head or do a piston soak.
@@DIYAutoworksNG Non-invasive is good.
Yea. It even stopped the oil consumption I was having. I think the Italian tuning plus the cleaner potentially unstuck the oil control rings. I would usually add a quart in 1500 miles or so, but the oil has remained at the top dot through 2000miles of high speed driving.
@@DIYAutoworksNG It's good to have collateral benefits instead of collateral damages. 😄
@@DIYAutoworksNGlso Is this Product less effective if i dont floor it ???? Meaning it wont clean carbon in city driving
This is awesome, thank you for sharing! and investing and taking the time to demonstrate this.
Thanks so much for taking the time to comment and particularly recognising that this 5-min clip took months in the making!
I'm running another multi-tank fuel system cleaner experiment! Just waiting to hit 1k miles before my first set of findings!
Very straight foward video. Well done
Thanks!
Remember , the goal is to KEEP YOUR REVS HIGH. It cleans better that way, long drives especially on the highway. Hotter -Cleaner
Clean and concise video, to the point with great image quality! Thumbs up and Subbed. That engine should be very happy now :)
Thanks for the tips and compliments!
Thanks for subbing too! 😀
High rpm’s don’t mater. The engine gets the same temp regardless of the rpm’s.
never had these problems. I only used ROZ 98 and better fuel. the pistons was so clean and I cleary saw the QR codes from the factory ^^
Nice. Unfortunately we don't have those higher octane fuels in my setting.
exactly, if you use premium fuel, you dont need any of these additives.
Beautiful, informative and great video. Keep up the good work and continue to make video like this! Thanks for sharing!
Thanks!
Straight to the point. Well done and thank you.
You're welcome!
That’s great preventative maintenance before problems might occur, there are fuels that have a lot of extra cleaning additives in them but most people don’t access to them. PEA based cleaners are definitely good cleaners if you can get it. Using an oil flush additive before an oil change is another good preventive maintenance measure for old cars/cars with high mileage.
I did use Gumout all in one cleaner that has PEA, and can't say I was as pleased with the Liqui Moly. 1up on the oil flush.
@@DIYAutoworksNG you liked gumout better?
Yes. Though I can say what would have happened if I used the Gumout in 5 fill ups.
Excellent video, perfect amount of info and length. Subbed
Awesome, thank you!
Some regular spirited driving helps by it's own.
I like seeing the low consumption numbers, but i also give it the beans every now and then.
That's the spirit. I now have a schedule for that.
great results! could you also try hot shots secret gasoline extereme?
Thanks, mate! I'll look into getting the hot shots. Haven't found it locally. Being HAZMAT, will be challenging to ship internationally.
Damn nice video man. I think a lot of people are scared to tamper with their vehicles and are uninformed. Keep up the good educational videos!!!
This means a lot. Thank you for taking time to comment!
Thank you.
Good video. Straight to the point.
Keep it up.
Thanks!
Hello, nice video documenting your experience. Btw, reading the SDS of this product it seems that it's almost kerosene (no PEA included as you said) but using it regularly and driving with high rpms it seemed to work on your engine. I have to try the same thing as you, but with kerosene.
Thanks for sharing! If you do have before and after footage, I won't mind seeing. Personally can't stomach adding kerosene to the tank for now. Maybe if I know better.
Interesting because PEA is the most common way to reduce carbon build up in an engine. PEA will increase carbon build up on new engines however reduce or remove it on an older engine.
@brarautorepairs How does PEA increase build up in newer engines?
I got 6 speeding tickets and crashed 3 cars using this method, but my cylinders are squeaky clean 👍
🤣🤣🤣
I appreciate the way you did this video, meat and fufu, no need for anything else.
🤣😂🤣 @ meat and fufu!
Ty , it was exacly for what i´m looking for , continue doing this type of reviwes to thos products
Thanks for taking the time to leave a comment. Means a lot. Yes, will continue. I have quite a bit of fuel system cleaner videos on the channel.
I run Liqui Moly Injector cleaner and use the Italian Tune up method. Works 100% for carbon build up
💯
what is the italian tune up method? I'm italian but i don't know this technique hahahha
Driving at high revs!
It's the Italian Tuneup what makes the cleaning.
Would be interesting to see what adding it right to the cylinders through the spark plugs would have done. Those tan deposits are super tough to remove with a wire brush even.
My old carborated harley pistons are cleaner than that after about the same km..... the wonders of 'modern' technology lol
You should see today's video! Not soaking but interesting all the same.
Use the Liqui-Moli oil treatment! It does work.
I use a can of it at every oil change.
Excellent video analysis. Thank you.
Much appreciated!
Así se debe de hacer una reseña!!! Excelente, gracias por el aporte
Gracias!
I use it and it works. But you gotta combine it with a good hard drive. I use it with half a tank and go push the car for 20-30 minutes HARD. Makes all the carbon go away. Also cleans the injectors good.
When I say push it hard I mean it, no highway, go to some mountain and go uphill, get some heat into the engine and get 7-8mpg out of it.
Thanks for sharing. Interesting take on pushing hard. That will certainly turn up the heat🔥
@@DIYAutoworksNG it also works for GDI engines, my forester XT never needs Valve cleaning because I push it hard and race it 3x a week. Just pulled the motor to do head gaskets (small leak at 150.000kms, about 500 races) and some seals, the Valves where quite clean.
Wow! Thanks for this insight. Will try this out.
Hmmm,....going to look for a mountain in south florida to try this out.....lol
@@flipd2830 you could also look for some backroads with a lot of cornering... That will keep the speed lower but you should be able to push the engine out of the corners, so it will heat up more than on the highway
The big problem with direct injection engines is the accumulation of carbon in the intake valves. In this video the cylinders are cleaner because the gasoline and the product is injected directly into the cylinder and does not pass through the valves. If the valves were shown, they still had carbon deposits. Only solution is a dual injection system like Toyota's
💯 Agree! I don't know why other manufacturers have not adopted dual injection.
They want service they dont f about us
So you are telling me the product is going to be less effective at cleaning carbon build on pistons on a car with port injection only????
Nope. It's should clean as well!
great video! wonderful execution
Thank you very much!
Thanks for the video :) I will give it a try
Cool
Is every comment written by a bot? Good lord.
Yeah these all fakes bot I only trust liqui moly injector cleaner since it work for me
Liquimoly is the only brand I trust for my cars maintenance try some today by going to your local automotive shop
Sure feels like it is lmfao
Think so lol
this is a great comment! my mileage went up 6 mpg after reading it! I'll be re-reading this comment every 500 miles from now on!
I would like to see the same test but without liqui moly... just keep those revs up and I bet you could get the same amount of cleaning.
Challenge accepted!
Agree
Agree, I have done borescope comparisons on my GDI engine using premium fuel. In as little as 15km of high rpm and multiple WOT runs significantly reduces carbon. th-cam.com/video/Zr6m5WGjpg4/w-d-xo.html
Hey, thanks for sharing. Seems like the video is offline. Followed the link but it pulled a blank screen.
When???@@DIYAutoworksNG
Thank you for informative content. Only thing i was hoping for but didnt get was why i shouldn't do this
Well... If you have access to top tier gas, then I guess you wouldn't need this because the fuel should have additives to reduce build up.
Fantastic video. Thanks
You're welcome!
It’s pretty much the same as breakfluid…
Remember Valves are in need of their ‚crusted surface‘.
It’s always good to know how to do the needs.
This is not true. Unrelated to brake fluid.
@@DIYAutoworksNG you better ask the company first 😎
Engine cleaner to put into your Oil than 15 min on 1,500 rpm before oil change… 99% Diesel 🤷♂️
You just pay a lot more 🤪😂😂
Love it mate!
Hello Friend how are you?
Excellent video, I really liked you, you are the only one who has really tried the product until you get good results, because many people on TH-cam only use one container and say that liqui moly doesn't work. 😢
Doing good. Thanks for the compliment. I'm yet to see a product that did cleaning when there's considerable build up in one shot.
@@DIYAutoworksNG Ah ok excellent friend it seems good to me.
Thank you for the great video!
My pleasure!
great video, awesome result
Couldn't agree more. Great result. Thanks for the feedback.
Great video that's to the point and evidential 💯. Subscribed
Thanks, and welcome to the channel😃🤝🏼
great work ! thank you !
Genial video, gracias!
Has probado el limpiador de inyectores de Liqui Moly?
Thanks! I have it in stock, but haven't used.
Nice video man i hadnt even thought of moly. Its unfortunately illegal in a bunch of states now but the best bang for buck carbon and all around fule system cleaner ive ever used was RXP Gas Kicker. Best before/after was on a 120k mi 1992 cadillac STS - an aluminum component 4.9L TBI V8. After driving for 200mi I thought the engine died at a stoplight and went to restart the car. It hadnt and my starter was mad at me. Thats just how crazy smooth it was running after blowing puffs of black and gray out the exhaust for the 1st 100mi.
Thanks a lot. Nice. Honestly I think a 200-mile non-stop trip with decent revs will do the trick. Thanks for sharing. Never heard of RXP Gas Kicker. Will have a look.
thank your film
Shout out to you from Sweden : )
Lovely! Thanks.
im really greatful for sharing this video ❤
Thanks for the feedback!
Great video! Thank you!

I was looking for a perfect video and I got yours 😁
Welcome! 🤝🏼
@@DIYAutoworksNG Thanks my friend.
Very good video. Thanks for sharing.
Thanks, mate.
Perfect. Thankyou.
You're welcome!
Thank you so much 🙏
You're welcome 😊
Your efforts are much appreciated.
Help us to know What is the difference between liqui moly valve cleaner and diesel purge?
Combustion for all like valve, piston and spray nozzle happens same time. So cleaning point starts from Diesel spray nozzle, valves then to piston. Would all these also cleaned.
A big thanks in advance
I just bought 5. I will use them in each filling.
My car is a V6 3.0L gasoline.
I hope to get good results 😄
Good luck! Let me know how it goes!
Best video review ever i like the camera down the cylinder to see before n after 👌👏👏👏
Thanks for the compliment! I do a lot of these fuel system cleaner videos, and have some more in the works!
Excellent video! I wonder which had more effect on carbon removal. Driving hard for extended periods of time aka “Italian tune up” or the additive.
Good question! Both definitely had an effect. I'm yet to test removing significant carbon build up with just a Italian tune up. Will look into this whenever next I have a planned long trip!
Great work
Thanks!
Great video. You earned my subscription !
Thank you!
this is video well done! looking for more video of you testing stuff! :D
I have quite some fuel system cleaner videos. More to come!
Thanks for the great video, well done! Did you consider pouring the additive into the combustion chambers and letting it soak over night?
Thanks for your compliment!
I tested it on soaking carboned up spark plugs and noticed that its not good as a soaking agent. Did nothing in terms of softening the deposits. That just tells me it needs heat to activate.
شكرا ياصديق
You're welcome
Hi, thanks for your video. By cleaning the pistons would Valve Clean help to reduce oil consumption? My car is a BMW with a M54 3.0 engine.
Thanks!
Excellent video
Thanks!
Does this clean carbon build up in valves too ? I have a Mazda CX5 diesel. Thank you
Very nice test, subscribed! Is your car direct injected? Recently I used "LIQUI MOLY 5153 PRO LINE FUEL INJECTION CLEANER" and my Mini Cooper S rides really smoother at low loads.
Thanks mate! Yep car is GDI.
