[TESTED] Liqui-Moly Diesel Intake Cleaner - DOES IT WORK??

There are lots of unfounded comments circulating about whether or not Liqui-Moly Diesel Intake Cleaner works. So I bought a can of the stuff and did some in-depth testing - including a before and after performance test, and a FULL removal of the manifold to see how clean it was after using this product!

HAS THIS VIDEO HELPED YOU??

Thanks, this is the sort of info that is helpful! Appreciate the effort and the thoroughness you've gone to!

[mikewasowski]

That was awesome. You wouldn’t believe how many questions you just answered. Nobody to date has done anything like this. Well done. Excellent video. As a double hit to reduction in cross sectional area, you also increase the effective surface roughness due ot the spot which has another profound effect on pressure losses along hahah intake, further restricting flow.

Thanks for making this! Saved me money and time.

Excellent quality video answered literarly all questions!

[TdAdventures]

Amazing video, top content👌🏼 helps me a lot.

[Chris-jydm]

Thanks so much for explaining the amount of air loss I didn’t realise the ECU controlled the amount of air mixture thanks again

Great video, finally a proper video that shows before and after looking forward to follow up video. I think it will be a product for the next video, if you have never cleaned your engine it will need striping down, no spray or a man in a van coming round and giving your car a hydrogen clean will clean it properly.

Good video pal. You deserve more subs.

[kiranb]

Good study pal...
Respect your hard work and patience.
Planning to use it on VW 1.6 TDI.

I had my 2014 pajero cleaned and put a catch can Good vid...

[StreetSyndicate]

Great video! Thanks so much for taking measurements and explaining the difference in volume of airflow before and after. Exactly what I was looking for!

What a bloody fantastic and thorough test of the product. I wish someone from Liqui-Moly reaches out to you and supports you testing again instead of hiding. I read almost all of the comments below but nobody has asked how you got the intake manifold so clean as you showed??? Could you let us know either here or in another video? I am now going to watch the follow up video.

Liquimoly is World class product.
Using Intake Manifold Cleaner
As early as possible
( After initial 40, 000 Km)
Will definitely improve to clean up carbon build-up
Thanks & Regards

What a fantastic video, thank you. This product like so many "wonder cans" that claim to clean your engine always just seem so unrealistic. Anyone who has ever cleaned a used BBQ grill can tell you that rinsing it under water with the detergent isn't going to get the job done. Now imagine a spray/additive that gets fractions of a second, in a highly diluted air/fuel mix form trying to wash away heavily cooked and caked, sticky, sooty residue. It's just simply not going to happen, not to any great degree. The biggest thing I took away from your video was about the performance remaining unchanged. Of course it makes obvious sense, but only now that I think about it, and that is thanks to you.

Thanks for doing this video, I've ordered this stuff for my Mercedes a class as i got a historic fault code for intake manifold swirl flap movement which is most likely due to carbon build up, so if this can improve or even delay having to remove the manifold(4 hours labour) for a while I'll be happy.

[GarthThomson]

Fitting a catch can results in dry not oily carbon buildup. It’d be interesting to see how it works on that rather than the degreasing job being asked of it here. Good video cheers

I bought a new Pajero - same model as yours really, from new I fitted a provent 200 filtered catch can, ecu remap including turn off the egr completely, so no oil and no soot entering my manifold, yes egr is goood for environment, but better emissions through less fuel use over the life of the engine as a whole . It does have DPF which will clean exhaust emissions up anyway .

[omarspost]

Ive used this product a few times.
Its designed for use with every service as a preventative or to clean light build up.
If its caked on from years of driving, this aint going to do much. No spray will.

[sweis]

I was gunna order some for my 2013 jetta tdi and use it every oil change as preventative, however after watching I think it might be better just to remove the intake piping and manifold and clean it manually .

Great vid and method. I'm always scared of these products incase carbon chunks break off and get stuck in the valve throat. A damn fine result from your mechanical cleaning though and a fair amount of crud in the bucket; I once did my egr valve and I looked like I'd spent a day down a coal mine.
