My 2017 Ram 2500 with the 6.4 Hemi engine calls for 0w40 and is pretty vague about recommending/requiring ONLY Pennzoil 0w40 SRT specific oil. This is not an SRT motor. The truck used quite a bit of oil in the first 5k miles on the factory fill. It was quite un-nerving to say the least. Almost a quart every 1200mi. The owners manual even has a section stating that high consumption is normal during the first few thousand miles while the engine breaks in. The oil consumption dropped of to a "normal" amount around 6K miles. I also changed the oil and used the far easier and 50% cheaper Mobil 1 0w40. Now I'm down to about a quart of consumption in the last 4K miles.
I understand the newest cars use more oil now than ever before. Dozens of videos of YT explain this blah blah blah low tension rings, DI, loose engine for fuel economy and long term durability.......... I don't really like it but the service manager stated to me that many people come in for oil changes that are 2-3 qts low. My friend has a Porsche Panamera and it uses a qt every 1k miles for the last 100k miles. My mom has a 2019 camry that uses 0w16 oil and it used a 1/2 qt on its first oci.
What I am worried about is not so much the consumption but the affect on the cat converter long term. What can I do to lessen the damage to the cat?
All of the 0w40 oils seem to be somewhat higher in zddp and phos. I want to keep using 0w40 but would like to hear from those much more in the know than I am.
Would the new dexos 2 0w40 m1 for the new corvette be better? Isn't dexos 2 supposed to better protect cats? Otherwise I am going to keep using the M1 FS 0w40 or switch to Castrol 0w40 or Pennzoil Euro 0w40.
Supposedly this engine was developed using 5w30 conventional so who the [censored] knows? I just wish it was easier than ordering a goofball "srt oil" from amazon when that oil may not be that good anyway.
