My engine is unmolested. Bought the truck used in 2018 with 30k miles if i remember correctly. 2014 5.7L Hemi, factory 392 and 65RFE trans. I've had my own HPT engine/trans tune since then.
Fast forward 121451 miles as of today 09/2022
She sees nothing but factory Mopar 339 oil filters with Castrol 5w30 synth changed whenever the oil reminder light goes off, no additives of any kind, so that's 7-9k miles UCI's. I removed the DOD chit in the tune as well, fact that was the very first thing i did once i did my very 1st read on the PCM calibration back in 2018. I loaded the factory tune a few months ago when gas reached $7/gallon but got bored of it very quickly with the cyl deactivation crap and the factory tune so i went back to my 91 steet tune with all my custom pcm/tcm settings. As i said many times, i let my truck idle as much as we need to specially when it gets a little hot around in the summer and we use the AC full on.
