Neighbor asked if I could pick him up 6 quarts of 0w20 oil when I told him I was going to Wally. I asked what brand he just said any big name will be fine so I decided between mobil 1 EP or Valvoline EP. Which one of the two do you guys prefer better? And if there’s a reason why choosing that brand. I’m assuming it’s going into one of his 2 Newer cars his Jeep Cherokee 4-banger or his wife’s Buick not sure of his or her driving style, but I know he changes oil every 5k as I had previous conversation with him. I also asked about a filter which he said he has. Thank you all in advance for your replies.
