Hello all,
Curious to get some opinions on this. I have a 2014 5.7L HEMI in a Ram 1500. It's going to be getting a 93 Octane tune soon, and ill probably do some drag runs at the track in Nov. Engine internals are stock, bolt on mods only.
I've been running Schaeffer's 5w20 with good results, though I have noticed oil pressure is a few lbs (45 psi vs 48 psi, still well within normal of course) lower when hot (Oil temps 215*F+) and my upper engine is a bit more noisy with the latest API SP revision of the oil. Nothing concerning, just nosier, I presume the SP oil is a bit more thinner when hot.
Since the engine may see some hard operation, I was thinking Pennzoil Ultra Platinum 0w40 may be a good pic. The 6.4L HEMI recommends it, and the rod/main/cam bearing clearances are all the same between the 2 engines. The oil pump rotor clearances are also the same. I know the MDS system might be a little bit picky when it comes to oil, but then again, the 6.4L uses the same solenoids for MDS, so im a bit torn if id have issues here.
Given the clearances are the same, the engine shouldn't have any major problems with it, but im curious to see what you guys think.
The PUP 0w40 looks like a really good oil, with a excellent add package... 200ppm+ of trinuclear moly is what makes it most appealing to me, plus being the factory fill for the 6.4/Supercharged 6.2L hemi engines..
