Anyone try this in the 3.5 EB? CERA TEC is popular in the Mercedes world (just added a treatment to my AMG) and also has some success stories in the Mustang world. https://pim.liqui-moly.de/pidoc/P000017/3721-CeraTec-34.0-en.pdf Combined with Liqui Moly 5W40, the treatment noticeably and immediately quieted down the valve-train on my M156 V8 (wasn't loud before, but now almost silent). Thankfully no ticking or issues on my SHO, so just considering this as a preventive measure. For reference, my SHO is tuned and I switched to Castrol Magnatec 5W30 (the updated full synthetic formula) after a 1500 mile break in, changed every 5K miles.
