This is my first post here and I have a quick question. I am Active duty military stationed in jacksonville florida where it reachs 100 some days during the summer and sometimes in the teens during winter. I just bought my wife a 08 kia sedona with 42k miles on the 3.8L( i believe to be a ford motor) I do not know the oil used by the previous owner but I was thinking about putting Pennzoil Platinum 5w20 in it. Is that recomended? and what should my OCI be?
