Can’t comment on IcePeak but I did/do have Blizzaks DMV2 275/60/20 on my Sierra and Michelin X-ice Snow 275/60/20 on my suburban and between the two Michelins have an edge overall..both work great but the Michelins perform slightly better..BUT price is a factor and for the right price I would do...
This lines up with the YT video I posted, Lee Rhodus with Deckman Oil says in the video he anticipates the quick lube oil change places prices are going to double to the end user paying customer.
Same, Costco oil isn't necessarily my first choice BUT with what is potentially coming and the insanely low price of this oil along with Costco's generous return policy I am overstocking my DIY inventory incase we hit the emergency break glass situation.
