The original 3.8L GDI engine in my daily driver 2013 Genesis Coupe lasted over 100k miles then ceased due to bad bearings despite regular 5k mile OCIs and Blackstone UOAs showing good wear #s on Mobil1 full synth 5w30 and oem filters. It had 1qt of oil burn every 5k miles that developed late and I kept it topped off.
Now the replacement 3.8L engine with around 60k miles that's out of a front collision Genesis has 2qt of oil burn every 5k miles and the UOAs show higher wear #s as well despite the lower miles. I'm wondering if people here that I've seen have much more experience than myself with oils believe that changing from Mobil1 to Amsoil along with using a oil additive like LM MoS2, Lubegard Biotech or Archoil 9100 would improve the UOA wear #s and help extend engine life.
The dealership service supervisor advised the MoS2 which they do sell btw wouldn't have prevented the bearings from going bad in my previous engine and advised that I not waste money on it but I want 2nd opinions here.
M1 is okay.Its probably not classified as a true synthetic but its hard to say for certain that its the fault of M1 either.Sometimes things just happen. Many people claim Mos2 clogs up but it never happened in my Hyundai as I drove it everyday. Sometimes bad things just happen lol.Originally Posted by tig1

Burning calls for Rotella T3 10W30 Dino oil .
I havent been able to find it anywhere in jugs, just 5gal pails.
OTW just run Formula Shell or QSGB
So Rotella is a band aid when you said there is "no magic band aids".
Yes. no Magic band aids.
Now why didn't that M1 diet protect his engine ?
