I have a drain plug on my 93 Kick, I let it drain overnite. Owners manual says it takes 5.3 pts, so far I put in 3.5 qts and just touches the tip of dipstick, any ideas here? I was going to drain it once more in several hundred miles before I drain a 3rd time to change the filter. Maybe the manual is wrong? I just didn't pay much attention to the amount in drain pan.
