The pentastar is easy on oil.
There really is not a bad choice on the market.
I use Pennzoil Platinum 0w-20, using the EVIC for oil changes. Which equals about 10k OCI. Only reason why I'm using Pennzoil is because my local wallyworld has it and it's relatively cheap. FCA uses Pennzoil for OEM fill in the 3.6. Not that it matters much, but I bought the lifetime Max care so, considering all those reasons, that's the reason for my choice.
But I would have no problem whatsoever using the OE or the SS oil in ANY engine.
