Liqui Moly ceratec engine oil additive any good?

[ezbtr]

Been hearing about this in one of my 2015 - 2020 Mustang 5.0 groups, also I use Mobil 1 full synthetic 5/20 oil as book states, 43K on my 2017 Mustang, some guys use "5w40 or 5w50 but mostly 5w40 rotella t6 and a bottle of ceretec." Thoughts? I'm in central TX, craazy long hot weather with fast cold spikes, car is daily driver, Thx guys

I concur, oil additives are snake oil. It’s marketing that sells them, it isn’t because they do anything for your engine. If you follow the owners manual and change your oil and filter at recommended intervals and use recommended viscosity oils you’ll get long engine life and there will be no failures due to oil failures.
I know of no case where an engine failed due to oil where it was changed per recommended intervals with recommended oil. Probably wont hurt using an oil additive but it’s a waste of $$$.
