Having tried Liqui Moly MOS2 in my 1995 BMW M3 I decided to try the modern ceramic based version in my future track car a 1998 BMW M3. The car was purchased 6 weeks earlier and had clearly fresh Rotella T6 5w/40 oil.

A container of Cera Tec was used as the car is 5.8 quart oil not "fuel" DOH!(if you catch that in the subtitle)
Room EQ Wizard (REW) software was used with a calibrated microphone 20-20KHz Frequency Spectrum Analysis(audio 🤓 ). Notice the graphs show beyond the audio spectrum. I have used these tools to setup audio in my home and cars and they work excellently.
I was very surprised the Fuji XT-20 audio is good enough to hear the difference as well, I was worried for sure about some type of AGC that could occur in their circuit. I have video from an e46 M3 as well without the calibrated mic. I may post that up if there is interest.
