i got my oil changed for the first time since i got my truck and i know it says mobil one on the cap but the guy at valvoline insisted the vavoline synthetic was better has any one ever heard of this.so they didnt have mobile 1 so i went with the valv synthetic.i also noticed the guy put in 5w-30 is that good or bad?then i was driving later today and i noticed my oil pressure was at about 75-80lbs with the throttle down and 50lbs at idle is that normal i dont know if its from the oil change or what but i thought my truck always ran about 50-60lbs with the throttle down and 45-50 at idle where should it be at and whats normal?
