Did first OA at 13,609 miles, ran the factory fill for 3000 miles and changed to Shell Rotella T 15W-40 to this point. I then ran Schaeffers 7000 series for almost 3000 mile but had to have a head gasket replaced. I found my truck in the bay with antifreeze standing in the cylinders, Story to long to post here. They drained the Schaeffers and put in motorcraft 15W-40 which I ran for a short while and did not bother with an OA. I now run Schaeffers supreme 9000 5W-40. Its first OA will be in the second post. Let me know what you think.
