Recently did a uoa on my f150 with the infamous 5.4 3v with 5w20 amsoil signature series in it with a motorcraft filter I’ve awlays heard of people bumping up to 5w30 in these engines so I decided to give it a whirl still running amsoil signature series now with an amsoil eao11 filter and did a uoa ..on this combo the results are in and a friend of mine will be posting the results again since I cannot get any cooperation uploading a photo via my iPhone... Let me know what you guys think I am very impressed and satisfied with the uoa results on this combo... OCI was 6300 miles
