I noticed a slight reduction in fuel consumption and quieter engine operation. Extension for 2K km between oil changes. I hope it adequately protects the mechanical parts because I plan to keep my vehicles for quite a while longer. Tested on Citroen C4, Toyota Yaris XP10, Kawasaki Z750

after 800 kilometers you can clearly see the difference. At idle the car is much smoother. And now it no longer raises the temperature. It also helps with oil consumption, as the Smart after about 1000 kilometers has not burned a drop of oil.

The sound and the engine’s operation seem to have become smoother. It should be noted that I use the car 1-2 times every 10 days because of my motorcycle, and I considered the use of such a product necessary. I have no comparison with something similar.

I put it in the Punto Evo 1.3 multijet diesel, since the engine has 250,000 km and, as expected for its mileage, it has a small oil consumption.
I hope this product helps.

Yes. It's worth it. The engine's behavior changed. (280,000 KM) And to see the difference, I simply added it into the engine with the oil that already had 1,500 km on it.

With fresh oils and the gearbox was making graap-groop noises on the engine (BMW F 650 GS). In my desperation I poured this in and from the first ride... no graap, no groop, gear changes were like powder.

I have a Skoda Octavia Scout 1.8tsi model 2010 with the well-known CDAA engine from the group. I have had the car since new and it currently has 100,000 kilometers. From the first years, when the car is driven for short distances in the city with a lot of stop-and-go for days, it has high oil consumption (about 500-700 ml every 1500-2000 km). I generally use it only for summer vacations and one or two trips in the winter, which is why it has so few kilometers. At the last service, after an oil change, I added the additive and after 2,000 kilometers when I checked the oil, it hadn't burned a drop! I also notice smoother engine operation and better gearbox engagement. Personally, from now on, with every oil change, I will add one of these as well.

After 1000 km since I installed it, I have noticed a reduction in consumption by almost 1 liter and the engine is quieter

it definitely reduced the noise from the diesel and it runs more smoothly now, as for protection we will find out after years... I don't believe it affects consumption.

Change every 10,000km 10w40 in Peugeot 106 with 390,000km.
I noticed various things during the changes, the oil doesn't turn black and has almost the same viscosity as if you put it in yesterday.
Fuel consumption decreased a bit, about 1.5 liters/100km.
The engine runs more smoothly.
Fair for its price.
It doesn't perform miracles.

It does a very good job. Smoother engine operation. The car runs like new (Mazda 3 2004).
Update. Oil consumption dropped by more than 75%.

I haven't understood if it works, however I am disappointed. After a lot of effort to remove the clutch cover on the engine to clean the oil indicator glass that had gotten dirty a little earlier from another product of the same company (engine cleaner) that had blackened the glass, I poured a little of this (about 30 ml into 2700 ml) into new golden oil and it blackened it immediately while it also adheres to the glass as I saw and will blacken it again soon. It is like melted thick lead, those of you who have an oil indicator stay away.

It works, I installed it in a Mazda Tribute, which was making noise from the valves side and it made a huge difference.

It's useless to generally put chemicals in our oils because they all have them; I tried it and I don't know if it worked or not, anyway my car continued to burn oil

2 bottles of this along with 4.5 kilos of oil in my 1997 Vitara managed to reduce the oil consumption by half (previously it burned 1 liter per 1000 km, now less than 500ml)

I used it on a 23-year-old Nissan Primera P12, due to conversion to gas it was burning oil, after application the oil consumption was greatly reduced, in the summer when I turned on the air conditioning the RPMs would drop a little at idle, now they are stable, it is definitely worth using, it's a shame that repair shops do not recommend it.

25-year-old car !!!!!
Check kilometers and emissions at the KTEO ..

I put it in a 2004 Ford Fiesta. Along with Quartz 7000 10w40 oil. I have owned the car for about 13 years and I have never exceeded 500 km with a full tank. With the use of this and your lubricant mentioned above, I reached 650 km. Tested two or three times. Maybe it's the combination, as I always used the cheapest oil I could find. As for the sound, I can hear a slight change.

Combined with the New generation Molygen 10w40 from Liqui Moly at a concentration of 4% after contacting the company itself (since the molygen already contains moly anti-friction and does not require further anti-friction despite this one). Well, the car is now NOISELESS and during cold engine start-up and during international driving, the 23-year-old Saxo car was definitely burning 150-200ml per 1000km, but after 5000km it hasn't burned a single ml of oil.

It does what it promises. It does its job and the cost is low. However, if it burns a lot of oil, you will see a slight decrease. It is good for issues with clogs

Quite a good product from Liqui Moly and it does what it promises .... in a diesel car it is a "breath" for the engine and especially in parts like the turbocharger that need a lot of attention ..... it does a perfect job there. Stay away from scooters and anything with a wet clutch ..... it causes damage!

Good, it might do what it claims. Don't listen to those who say they saw miracles and other things. For me, it only burns oil in the city, not a drop on long trips. So if I had used it before a long trip, I would have had the illusion that the additive worked wonders. Now, for sound from hydraulic lifters, you won't see anything better. It does its job and the cost is low, just if it burns a lot of oil, you will see a small reduction. It's good for gasket issues

Very good product. Valve noise due to cold engine disappeared. Rattling in the timing chain tensioner in the TSI engine decreased to a minimum. The engine runs more quietly. Before you put it in the engine, mix it well.

Very good, it reduces the squeaking when the machine is cold and does not heat up as much as before when I use it

The noise has been reduced, especially when the engine is cold. Bmw E46 318Ci M43. I will buy it to use it after changing the oil in my other cars. Another good product from Liqui Moly.

Used in a RENAULT CLIO and immediately the squeaking and noise at low revs reduced...

For fuel consumption, if I notice any difference, I will come back later.

I used it on a motorcycle and car, especially on the motorcycle that has a wet clutch, I have the impression that it softened!

On a simultaneous trip with 2 cars, where one burned about 800 grams of oil in 500 km, upon return, after filling up the burnt oil and the 125ml oil additive, the cars returned exactly as they started!
I didn't believe from the beginning that it would do what it claimed!!
Having tried other oil additives as well.
Golf 4 1.4 2000 model and Audi A6 2.0 from 2008, with 200,000 and 250,000 km respectively

This product is absolutely useless. The machine's fuel consumption increased to 2,000 km after only 500 km, even further away.

The product that highlighted LIQUI MOLY.
Those who tried it loved it and don't
change it. Among other things, it reduces
fuel and lubricant consumption
reduces wear and in case of loss
of lubricant allows the engine to operate
for a long time without being destroyed. (due to the
strong lubricating film it creates in all
moving parts). !!
