I have a 2019 Jeep Grand Cherokee with a V6 and it calls for 0-20 oil. It seems to be a bit noisy in the engine bay. I also just got a 2021 GMC Canyon V6 and it calls for 5-30 oil. Is this the new standard as I see most new GMC vehicles need 5-30. My Jeep seems like it would benefit from a bit thicker oil, but is under warranty. I will use what they reccomend, just a question I'm asking because when warranty is over i will probably use 5-30 in the jeep. The Jeep dealer uses Pennzoil and I'm not a fan, but I have free oil changes for the base warranty period. BTW both of these vehicles use a canister type filter, seems like a PIA to me. My belief is that it is designed to make it owner unfriendly so you get someone to do it in MHO.
