This is a great oil and my engine seems to be a little quieter . I cannot tell the difference between Liqui Moly and Mobil 1 oil. My favorite feature is the ability to use a UV light to check for any possible leaks after an oil change service. I recommend this oil to everyone. Get the Liqui Moly bag/case to carry an extra liter in the trunk along with your UV flashlight.

I really liked the way my car functioned on this oil. Wasnt a crazy difference, but it was noticeable. However my only complaint is that i still needed to add lucas oil stabilizer. My car never burns oil, but using this oil alone i saw the level decrease when i checked it out, so i added some lucas, everything back to normal. Great product overall.

Use this in my 19 RS3 running e85 without any issue, changes every 5,000 mi or so using FCP's wonderful warranty. Nice because you can check for leaks as it's glow in the dark, fair price, and oil isn't too contaminated or doesn't get too hot after a few thousand miles with spirited driving.

Best oil I have ever used. Hands fown

Good for detecting leaks but my mechanic said this shouldn’t be used regularly, just for diagnosis. It’s very black after very minimal mileage but it’s caused no damage.

You can't go wrong with Liqui Moly. Amazing stuff.

The thing about this oil is the green fluorescent color. Makes the oil more noticeable which is great for keeping an eye out for leaking seals on engines with more, rather than less, mileage. Personally, I rotate between this and Synthoil premium in my MkVI GTI's 2.0 TSI.

I used to think that oil was just oil, until I put Liqui-Molygen into my BMW and my Mercedes Benz. It made the BMW noisy lifters and turbo noise whisper quiet. The engine runs quieter and a little cooler. This oil is not simple engine oil that you can go to Walmart and buy. It is worth the price for the performance.

Immediately noticed a difference. I do a lot of highway miles. Felt smoother and hopefully less burn off. We will see

Unbeatable oil for my 325xi
