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
