04 Silverado, 186k been using Mobile 1 full synthetic for the last 10+ years. Runs great!
My old Silverado 5.3 developed a ticking around 350k. I went from the recommended 5w-30 to 10w-40 and it stopped. Also slowed the oil leak too.
I run 5w30 liquimoly molygen since i tow a lot on my 2019 5.3
Oil pressures are happy and so far so good.
Have an 07 Silverado bought new first oil change switched over to Mobil one used that until one of the hurricanes hit Louisiana and started having a problem getting it so switched over to Pennzoil full synthetic. Truck has 368000 on it and seems to be still going strong so I’d say it’s your choice.
I use that Valvoline, sometimes throw in random fully synthetic oils I get in bulk from an auction. I feel like it contributed to a rear main seal leak. Thinking of switching to a 5w40
