Car runs smooth and quiet. I've recently tried this after using Valvoline for the past several years. FCP thanks for the fast delivery!

I pretty immediately noticed louder engine/valvetrain noise with this oil, as opposed to the normal gray jugs of liquimoly. Will go back to that + ceratec to confirm and stick with it if I'm correct. I feel like i had the greatest quieting with that combo, and liquimoly says not to use aditives with the green stuff.

Oil is green, looks cool.

Twice the price of synthetic mobile 1! Makes the lifetime guarantee a little harder to justify. Good oil though.

I did an oil change on my 2018 Audi Q5 and this oil was perfect. It has all of the engine additives to protect the motor in my car, and it runs fantastic! I would recommend this to anyone looking for a top-quality motor oil. It also has fluorescent dye in it so if your car develops an oil leak, you can see where oil is leaking from by shining a black light on it!

After reading the other reviews I figured I'd give this a shot over the usual Castrol 5w-40 I usually put in my 2011 Audi A3 2.0T. I noticed immediately how much quieter the start up and idle are. Before it always sounded a little "diesely" which I just wrote off as "well, it's direct injection". No, don't do that. This oil has quieted down that clickity clack entire and sounds and feels so much smoother. I'm not a paid shill, just really impressed with the difference this oil makes.

I switched to this oil after using the factory VW oil for the last 130,000 miles, as well as adding a can of their M0s2 additive. I have noticed the oil temperatures consistently stay lower than they did before, it’s nothing crazy but where I know I’d always have my temp at 205f during this stretch of road I now see 199f and if I’m coasting for a while it will drop down to 180f which is wild! I have to assume that it’s because the lubrication is that much better that there’s less friction and subsequently less heat. It’s also worth noting that the bigger bottles have a handy pour spout built in!

I have been using Molygen in my 1998 Volvo S70 T5 for almost a year now! With this cars high pressure turbo and tendency to clog up on the PCV system its worth running a quality oil. The Volvo runs amazing on this stuff. I literally pull out the same amount of oil I put in every time. Don't have any burning issues and she runs really great! A+ for this oil.

Noticed a difference with my car when I switched from Mobil 1 5w-40 to this Molygen 5w-40. The engine ran smoother and quieter and hasn't burned any oil between changes compared to the Mobil 1 where I got an oil warning in between changes to add more oil.

This stuff is better than their Blue or Purple bottles of oil! It has their "Ceratec - Molecular Friction Control" additive already mixed in. The only oil I put in my Audi with over 100k miles.
