Good to know!I ran the liquimoly ceratec in my car and when I got the oil analysis done, blackstone said it looks no different than any other oil. After that I've never purchased it again.

I tried ceratec and didn't notice a difference. Tried it on my friends Benz GLK which had a noisy engine and didn't notice much either.
If it had the M276 DI engine it could have been a few things. They updated the chain tensioners, also had a check valve that installed into the head, noisy HPFP, or just injector noise. The ceratec wouldn't have helped any of that.
I haven't used that in a while (OK...long time) but remember a nice minty smell.Here you go. Since 1923. Marvel Mystery Oil
You're right. Mine runs far better after the car wash...The placebo effect is very strong with many of these reptilian oil enhancers.
My car runs better after an oil change. It runs even moar better after a car wash & detail. Scientific farce, I mean fact.
Perhaps the company is owned by Guido Franch or Tim Johnston...
In all fairness to the posters who have noticed an improvement - they may be right.
When something gets noticeably quieter, we notice it - but we don't notice if it gets louder again over time but we are impressed that it got quieter and continue to believe that.
It wasn't that long ago that it was common to pour sawdust into oil to stop leaks and quiet engines. It worked, but nobody would say that it was a proper fix or that it was good for the engines.
When we spend money, we want to believe that we spent it wisely. We want to believe the hype and - after we've spent the money and noticed the "improvement", then we're happy to tell others.
I absolutely believe Jim that he had an improvement after using this stuff, but I also think that there was no lasting improvement but he never noticed the slow "return to normal"
Hell, I always notice a difference after an oil change. I doubt that it is actually there but I want to notice a difference.
That's how our brains work.
I agree about the placebo effect for lots of things. All I can say is that when I got my SE I noticed the same clickety clack sounds from the engine that I hear in the videos guys have posted. I always comment that the engine sounds terrible and everyone responds by saying that they all sound like that. After adding the Cerma engine treatment my engine still sounds great even at a cold startup. I'm at 74,000 miles now and it sounds great. The next time a friend happens to stop by on the weekend when I haven't started the engine overnight I'll have him start it and record the sound and post it. I have no vested interest at all in Cerma. Like I said I learned about it on the Veloster Turbo forum.
If that effect can be measured, what they've produced is a viscosity modifier.
Lucas products will provide a similar result, in that regard.
When recording a running engine, most microphones will pick up valve noise and things of that nature much more readily than other sounds. Even the decent setup that I used to record the engine in my G20t really made all those sounds pop; and if the hood is open it'll add a bit of resonance. You really need a larger diaphragm to properly record an engine; or post-processing. Neither cameras nor microphones really do what we hope they will. They need to be pushed around and bullied into performance.
Another issue is focus. You're hearing only the engine; which rarely ever happens. It's the loudest thing happening in the recording, and the most focused in regard to the sound field. It's going to sound different than it does in person.
Here's an example. Yes, this video is truly terrible from any perspective, and it's supposed to be terrible; but the idle recording is done well. It's only a few seconds in. The rest is deliberately cringy nonsense:
Couldn't do any better given some recent brain and lung damage after a bout with a surprisingly annoying illness, so I figured I'd just use the warm-up cut and make fun of myself.
Later on, there's a recording of the mostly factory sound system, and you can hear that the microphone capsule is actually pretty darn solid. This should skip all the other stuff and take you right there:
The engine is nowhere near that noisy in person. The microphone is simply picking up everything at different levels than an ear does. The reason the music sounds so good is the cabin itself managing lower frequencies. If I was filming a movie or making a new car commercial, I'd level it; but I don't want anyone buying that thing and coming back later to complain. Best to have a flat idle recording and an idiot on commentary... Then fill it with dad jokes like your grandfather trying to be a "hip Youtuber" to see how cringy I can make it.
This isn't meant to be any manner of advertisement on the forum, mind you. I would assume everyone here already has at least a relatively new Golf. I just happened to have shot this last week after finally opening the door to the outside world again, and it's coincidentally topical in this regard.
The Cerma engine treatment does not alter viscosity. It coats surfaces.
