So i have the 2015 Ram 1500 with 5.7 L Hemi and i used till now the PP Pennzoil Platinum 5w-20 engine oil with Mopar filter and i am seeing lot of mixed info about people moving to PUP Pennzoil Ultra Platium 5w-20 . I am due for other oil change in few weeks and wanted to know if i should move to PUP or stick to PP? I am in Central California weather.
Thanks,
