Hey all, i'm new here and had a quick question. Currently I use Quaker State full synthetic in my 2004 Ford F-150 4.6L. I saw that Kendall synthetic blend is $3.69/qt. and synthetic is $5/qt. Right now I either spend $6.29/qt. or $19 for 5 qts. Should I make the switch to Kendall or stay with QS? Thanks
