I've got a 2011 Silverado with the 4.3 V6. Normally it takes the short AC pf47e filter, but I'd like to use the longer AC pf52e instead. There is plenty of room for the extra length of the different filter from what I can see. (I might actually use the Supertech equilivant ST3890 it looks the same) How much extra oil for the longer filter? The truck takes 4.5 quarts with the smaller filter. I was thinking maybe 1/4 quart. When Chevy spec'd these filters in the past (short filter for 2 wheel, long filter for 4x4) I don't know if the owner's manuals said the correct oil amount difference. Any help would be appreciated.
