93 C1500 5.7l 152,500 miles
Out- QS HM 10w40 w HPL EC30 Fram PH5, 6k on oil and came out thick and super dark brown. Used 2 filters during the run and had 2 qts of make up 10w40 ST blend and 0/5w40 PP SRT at filter changes. Will need to do the valve cover gaskets and pcv and breather grommets it has a small leak now at them- think EC cleaned up some gunk that had it sealed. Will post the filter later on.
In- QSFS 5w40 Euro w Mobil 1 M1 302A.
Never ran the Mobil filter before but I did like that is is about 1/2" longer than the Fram.
