Does Liqui Moly CeraTec work? Let's find out!

Does Liqui Moly CeraTec actually work? The manufacturer claims it will reduces friction and wear, prevents metal-to-metal contact, and reduces fuel consumption. In this video, we test those claims.

Sorry it's taken me so long to post the links to the products I've used below.

This guy is underrated and extremely practical/professional

No one comes close to project farms videos, professionally made in the comfort of his own garage and property - no sponsors, no bs. Best testing on the web, bar-none! Thank you for your attention to detail!

I used to have to add oil every two weeks. Since I use ceratec, I add oil only every 14 days. Sometimes even only about twice a month

You are still replying to almost every comment. After all these years. YouTube fame hasn't gotten up to you! You are a good man and i wish i could buy you a drink some day. Thank you for every single video you ever posted. I mean it.

After buying Liqui Moly CeraTec, I noticed an immediate difference in my bank account.

[Leo-fkch]

Heavy equipment owner operator with 32 machines in use daily, plus two Kenworths that pull 80, 000 loads weekly. I have two full time mechanics, they both do all maintenance and overhauls. I’ve been extremely vigil about oil, using the best possible for extremely harsh operating environments. Five years ago we switched to Liqui Moly after years of using another highly recommended friction modifier. The real proof is when one of my diesels is overhauled, old bearing surfaces scrutinized and compared to industry averages. Using the Liquid Moly has given my equipment decent results. Mostly in camshaft and main bearing wear. We just finished overhauling the engine in the Kenworth, a T680 with the Cummins 650 horsepower power plant. 690, 000 miles of extreme duty, used to pull our heaviest excavators and dozers. The camshaft and bearing wear were just under 50% of normal, pretty impressive.
For light duty, cars and small pickups, I’d think it would yield as good if not better results.

I would like to see a "Leader Board" for fuel and oil additives similar to how Top Gear had for their celebrity lap times. This would help viewers understand where other products compare to the current video test.

I have been using this stuff for years, and without doubt I'd say it is the best you can buy. I'm 71 and have been fixing cars and using additives for over 50 years so I've tried most of them. I have a 2007 Audi A6 2.0 TDi which I bought in 2009 and has now done 322, 000 miles on the original engine with no problems or major engine repairs, oil changes around every 18, 000 miles and a can of this stuff at every change. It still sounds as sweet and smooth as the day I bought it with 17, 000 miles on it. I also have a 2019 A6 Avant 40TDi, bought last October. It ran really well, but I added a can of Ceratec and the miles per gallon has increased noticeably now it's had the required few hundred miles to work-in, plus it's even quieter than before. I have several friends who have used it and every one of them is amazed at the difference in the way their cars run. I'll never run an engine without it in.

My e39 M5 burned about 1 quart of oil every 750-1000 miles. I've been using Ceratec between oil changes and I made it to about 3400 miles before needing to add a quart. It's been beneficial in my use.

[gonzalotapia]

IDK, but applied it to my 2010's 200k km corolla (120k miles) and the change is astounding. Engine vibrates so much less, it delivers smooth power, accelerates faster. It feels like the engine rejuvenated at least 10 years. It didn't affected fuel consumption (at least measurably), but the car feels so much smoother now. Effect isn't immediate. It took almost a week (100 miles) to get to current state.
The restoration in power is measurable because now it don't have to downshift in uphill while cruise control is on, on light hills. Before, even the minimum hill made the car to downshift and jerk violently.

I believe you have come up with the best type of non bias lubrication tester. Those who intervene during the test or touch the equipment during the test are affecting the results. Keep up the honest evaluation of products. Thank you.

This is over 4 years later. I use this product in my 2020 Ford Ka/Figo. It has a 3 cyl. engine and the reduction of the noise was significant. I approve this product IMO.

[Traderjoe]

Really, nobody does testing any better than this channel!

[jusb]

wow, a great deal of time and effort goes to making these, thank you!

[MikesGearGarage]

Love how you're actually using proper testing/scientific methodology to test. Well done.

[matreyia]

When I used this the first time, I literally noticed immediate reduction of noise and increase in mpg as well as restored power. It was very unexpected. So I used this on every single car I work on and it is the same each time. Even clients notice and comment. So yeah, this works in my personal experience.

[briand.]

I have to admit, I truly appreciate that you FF through the more mundane parts of the video as to get to the key points of your tests. Great video as always. . .

[puffnstuff]

1% is well within the margin of error as there could actually be several mitigating factors and I wouldn't give credit to the product for it.

[srhatfield]

This is over 3 years later, and something that I found out is that the gen 3 Coyote engines in 2018 and newer Mustang GTs have a "typewriter tick" problem from the factory, which drives people a little nutso... and adding a quart of CeraTec during an oil change actually makes this go away! So there's at least one good use for this stuff 🙂

[walkawayjoe]

I have used this stuff for a few years and all I can say is it made a great difference in my 2013 honda accord. It's one of those earthdream 4 bangers with direct injection that are noisy as crap and vibrate alot. Definitely not the great honda engines I used to drive from the 80's and 90's. Although they feel like they make about 50% more hp now. I think they should be a little better on fuel than they are. The old Hondas got way better mileage. Like 40 around town. The first time I used this Ceratec stuff it immediately quited down the noisy valve train that always rattles on start up and mpg's went up to 27 from a little over 21 . That is around town mpg daily driven same route everyday to work and back so that has made for a pretty good test. I was shocked by the improvement. Seemed to improve more with every tank of fuel til it got to 27 mpg avg. It rarely see's any hwy miles ever. That's been my experience so thought I would share. I just came across this video and never saw any test on it before. Not much of a youtuber, guess I need to check out all your other stuff
