You are probably using an original or original length dipstick with one of the newer tubes. When I tried to a new chrome tube with an original stick, the new tube is shorter allowing the dipstick to go too far down. You could either get a matched pair or get one of the newer chrome dipsticks from Mopar which will probably work. You should be using at least 5 qts of oil so regardless of what your stick is showing, put 5 in.
