It's been a while since I checked in if the major oil brands have altered their bases/add packs and if formerly good options have fallen out of favor. Can you guys recommend the current best oil for my cars? I have been using Mobil 1 Extended Performance for all but two of them with 5000-7000 mile changes with the exception of one that gets 3000 but that one will not be changing what it uses and the newest member that has been using RP. My fleet is listed below with the oil they currently are using and other details, none use oil currently.
2017 Ram limited 5.7, Mobil 1 Extended Performance 5w20
2012 Sequoia platinum 5.7, Mobil 1 Extended Performance 5w20
2006 LS430, Mobil 1 Extended Performance 5w30
2005 Civic LX 1.7, Mobil 1 Extended Performance 5w20
2003 Ram, 410cid NOVI 2000, Zrod 10w30
2002 LS430 (daily), 5w30 Royal P
2000 WJ 4.0, Mobil 1 Extended Performance 5w30
1999 RX 300, 0w-40 euro Mobil 1 Extended Performance
All use boss filters. I am not interested in long OCIs but I do run the V8s to the tune of my daily doing 4 hours plus at 130 on trips at times. Redline is hit at least once per drive but usually 5-10 times as well, keep this stress level in mind please. I don't expect an oil to magic away all wear but I want to minimize it since an engine replacement takes a day or so and it's annoying.
The daily is running RP on 2k mile changes to clean it up since I bought it with a fairly varnished engine at 200k miles and didn't like what I saw when I had the engine partially apart resealing the covers, pan, upper pan, mains etc. I don't have it's 2nd engine ready yet so I decided to run the RP to clean it like some posters a few years back claimed it does. Did I waste 6 oil changes?
Thanks for the help and for reading
