Review: 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.
Review: 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.

## Questions & Answers

**Q: Is this product 100% synthetic oil?**
A: Yes

**Q: Can this be mixed with other full synthetic motor oils? If not all can mix, what kind of groups cant go with it. My car holds 6l of oil.**
A: Those that say you cannot mix are incorrect. ALL OIL MANUFACTURERS are required to allow their oil to mix. It is recommended to use synthetic with synthetic but if down a quart in a pinch, mineral (regular) motor oil  or synthetic blend oil can be used.  Try to use the same weight if possible, but if you have 5W-40 Synthetic in your car which is hard to find, and need to add or top off at a service station, use the more readily stocked 5W-30 if it's the only option.   THIS IS FROM LIQUI-MOLY's own Website  FAQ section....  "Refilling motor oil: Can you mix motor oil in the car?
The mixability of modern motor oils with one another, regardless of the type, must be possible under any circumstances. For it is not always guaranteed that the average car driver will know which motor oil was used by the garage in an oil change."

**Q: Does this have the motor oil additive - liqui moly mos2 anti-friction already in it? and if so how much?**
A: This doesn't contain Molybdenum.  Phosphorous and calcium are anti-wear, per BITOG.

**Q: I have honda civic 2013 ..... i used shell helix ultra 5w30.....is liquimoly 5w40 fine for it?**
A: i would go with redline 5w20. i hav3 an 06 civic that calls for 5w20. Redline 5w20 is more like a 5w30 at operating tempreture plus it is a true synthetic ester oil that will out last and out perform all dino oils and group 3+

### ⭐⭐⭐⭐⭐ Noticeably smoother running engine in conjunction with other Liqui Moly products!
*by G***G on July 19, 2020*

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.
