2021 F250 4x4 6.2 V8
Long story short brought truck home everything sounded great .
1000 miles I wanted to get factory fill out , I'm sure Motorcraft syn. blend 5w30 .
Put in 7 quarts Mobil 5w30 ep , engine sounded ticky. Ran it 300 miles dumped it and put in Quaker State 5w30 . Instantly back to quiet .
I will be towing a 6,000 lb trailer and was thinking of doing a home brew of 5 quarts of 5w30 and 2 quarts 5w40 all Quaker State during summer towing season . Straight Quaker State 5w30 for Michigan winter .
?? Any thoughts on this ?
