i use T4 or mobil delvac in all my cars and trucks even my new car,and lawn mowers,
i buy which is cheaper at walmart at the time, u might of been
lugging the motor down causing pressure to drop, and it will be higher presure when cold,because its thicker, get thin as it gets hot, the oil filter had nothing due with it,
i have a freightliner truck, and i always figured if that oil was good enough for it,it wa good enough for any motor i have
u will save alot on engine wear, i been using those oils in everything for 40 years
