Haven't been here a while. I hope every one doing well. I pass to my youngest brother my old 05 ford 5.4 3v expedition 195k miles ( his first vehicles ), run and drive perfect, no smoke or leak or lost any oil, under the truck is bone dry. I alway change the oil every 6 month with mobil super 5000 5w20 ( some time 5w30 ) ( around 2000-3500 miles ) with motorcraft oil filter .
Its still have original cam phaser and it does making that noise ( sound like diesel ) I mean to change it, but with that miles, I just drive it til it broke , other then that the truck run extremely smooth.
reason I want change to another dino oil from mobil super 5000 , is I think the cam phaser degrade the oil and made the oil quality going bad early. first because when I change the oil and drive about 2 month , cam phaser start making dry noise start when I park it longer then a day or start on very hot day when park more then 8 hours. If I change the oil to flesh oil, it dont matter how long I park, it alway start smooth with no dry noise start. also no check engine light. check engine light go away when I change to flesh oil. I know this because it happen many time in the past.
I like stick with quality dino oil on this truck, dont want risk it have a problem ( leak, smoke.... since quality synthetic oil do clean up all the gunk and might cause seal to leak ), I dont believe in high miles oil either, for me either dino oil or synthetic. any dino oil that better and not break out early then mobil super 5000.
