I don't use Anything Else
I have a 2007 Audi A4, and this is the only oil I have used for it since I bought it in 2020. My car is now climbing towards 250K miles, and this oil has never caused me any issues. I live in the Midwestern US, so I get warm summers and cold winters, and this oil is perfect for me all year round; it is not too thin that it feels nady during winter, nor too thick that it feels sluggish in the summer. I am not a big car guy, so I cannot speak for the actual oil contents or anything specific, but I do know that this oil is some of the best for my car in general. Because of that, I would say that the cost of the 5 liters is justified, especially because these cars are known for burning oil. Because I have used this oil exclusively, I cannot say for certain that it "helps" my fuel economy, but I will say that it definitely does not hurt it based on the car's specs. I will continue to buy this for as long as I have my car; I couldn't be happier with it.

My Audi LOVES this oil
This is the absolute best engine oil I have ever used. I have been changing my own oil for over 15 years. I just don't trust places like Jiffy Lube, because I suspect they use cheap, inferior oils. I also don't trust their low-wage employees, because my mother visited such a place once with her car and they didn't screw the drain plug on properly, so she lost all of her oil on the way home. This is why the old saying goes, "if you want something done right, do it yourself," so I now change my own oil, as well as my mom's and my girlfriend's. Anyway, back to the oil.... I have been using Castrol Full Synthetic motor oil on my 2000 Audi A4 with 235 000 miles. I used Castrol, because this is what the dealership uses. But after learning that the Germans don't use Castrol, but rather use Liqui Moly or Motul, I decided to give this a try. I have always held the belief that all major brand motor oils are more or less the same. I was wrong. Very wrong. I decided to go with Liqui Moly instead of Motul, because I learned that Liqui Moly is the more popular and slightly less expensive brand; I also liked the cool purple jug it comes in. Before changing oils, I figured I should do an engine flush, so I also ordered the Liqui Moly Pro-Line Engine Flush. I have never used an engine flush before, but figured that since I was changing oil brands, I should do it. Plus it had really good reviews, so I figured it won't hurt. Wow! Wow! Wow!! My car runs and drives like a brand new car. It's unbelievable. I would have never imagined that the type of oil would make that much of a difference. The engine flush worked great and once I put this oil in, I think I heard my Audi whisper "Danke Schoen" as the engine ran much smoother and quieter. It seems I have more torque and when my turbo kicks in, it pulls much faster. I wish I would have known about this oil years ago! I will never use another brand of oil for my Audi again. Btw, make sure to use a high-quality oil filter as well. I tend to stick with Bosch or Mann filters.

Noticeably smoother running engine in conjunction with other Liqui Moly products!
I've used this specific Liqui Moly blend on two different oil changes. One with a Mercedes V12 biturbo and another with a VW 2.0L turbo. On both applications, I've also used the Liqui Moly Engine flush. Finish up the oil change with Liqui Moly Ceratec, and I guarantee that you'll feel that the engine runs smoother! For the V12, I always ran Mobil 1 0W40, but there was always an issue with adding a quart every 1k miles. For the VW, I always added every 1k as well. I've always used full synthetic, but for whatever reason, this Liqui Moly is quite nice. Bottle is easy to use and ergonomic in a sense, compared to many 5L or 5qt bottles I've used. Since the specs are only 229.3 for Mercedes, I'll upgrade to the New Generation Liqui Moly that looks like green antifreeze for 229.5 Mercedes specification. Tye V12 requires 229.5, but that just means that I'll change it at 5k mark rather than 10k+. The only difference is the mileage between changes. I also have a V8 Mercedes that uses the 229.5 specification, so moving forward, I'll use that one for my Mercedes vehicles. I'll keep an eye on the quality. Otherwise, right now, it is an oil in which I immediately noticed a smoother running engine.

This was considered an upgrade over the stock oil

Best you can buy anywhere
A BMW technician for 37 years and I can’t tell you how much I love it. It’s in all my cars. Even my Corvette and the 1952 Ford tractor. When I first started using it years ago I was using a little oil between changes on my x3. It quit using any oil between changes. A 160k and a new owner and it still uses no oil. It’s a must have

Alien Blood green
Alright, hold onto your car seats because I've got the scoop on Liqui Moly 2040 Synthoil Premium, and let me tell you, this stuff is like a potion brewed from the tears of Demonic Alien Blood. And yes, it's even neon green to prove it! I kid you not, this oil is like the elixir of life for your engine. Slipping it in is like giving your car a spa day in an otherworldly oasis. The neon green hue isn't just for looks – it's like a power-up for your vehicle, making it feel like it's ready to conquer the galaxy. But don't let the intergalactic vibe fool you – this oil means serious business. It's got the performance to back up its extraterrestrial origins. Smooth rides, quieter purrs, and an overall engine orchestra that could rival an alien symphony – that's what you're signing up for. Now, I know what you're thinking: "Neon green, alien tears – is this some sort of joke?" Well, joke's on you if you miss out on the wonders of this concoction. Seriously, my engine's been running like it's on a mission to outdo the Millennium Falcon. And let's be real, any oil that can make your car feel like it's flying through space is worth a shot. So, in summary, Liqui Moly 2040 Synthoil Premium is not just oil – it's like a ticket to a parallel universe where engines run smoother and cars feel like they're possessed by a friendly alien spirit. Don't let your ride miss out on the fun; give it a taste of

Buen aceite, no es la gran maravilla pero si tiene una mejor lubricación que la mayoría de los aceites sintéticos, un poco caro para lo que realmente hace

J’ai récemment testé la Liqui Moly 2040 Premium 5W-40 Huile moteur synthétique - Flacon de 1 litre sur mon véhicule, et je dois dire que je suis très impressionné par la qualité de ce produit. Liqui Moly est une marque reconnue en Europe et dans le milieu automobile, et cette huile ne fait pas exception. Dès la première utilisation, j’ai remarqué que le moteur tournait plus rond, avec moins de vibrations et un fonctionnement plus silencieux. Le démarrage à froid est devenu plus fluide, ce qui est un vrai plus durant nos hivers québécois. Sa composition synthétique premium assure une excellente lubrification des pièces mécaniques et une protection optimale contre l’usure. J’apprécie particulièrement le fait qu’elle soit conforme aux normes et homologations des grands constructeurs européens, ce qui me donne confiance dans sa performance et sa durabilité. De plus, sa stabilité à haute température est remarquable, ce qui garantit une protection même lors de longues distances sur l’autoroute. Le format de 1 litre est pratique pour faire l’appoint ou pour ceux qui préfèrent gérer eux-mêmes leur entretien. Le flacon est solide, avec un bouchon qui se referme bien, évitant tout risque de fuite. Bref, si vous cherchez une huile moteur de qualité supérieure qui protège efficacement votre moteur et prolonge sa durée de vie, je recommande vivement ce produit. Je rachèterai sans hésiter !
