oil change

[tahoe02]

I just changed the oil on my 2002 chevy tahoe 5.3 v8 and i used 6 quartz of 5.30 My oil pressure gauge sits at 40 then jumps to 60-70 while driving. I checked the dip stick and it looks like its right below the 5th lil whole. Should i add more oil ?

is it in between marks? that's good oil pressure.

yeah the dip stick i have has 5 wholes in it, im guess each whole is a quart so when i pull it its in between the 5th and 4th quart. But i know for a fact i put 6 quartz and like .23 because i bout a jug that is 5+ quartz and i bout an extra quart.
