just changed the oil for a buddy of mine, grand cherokee with the 5.7 Hemi, 33,000 miles. I used QS 5W20 synthetic and a Mopar filter, 7 quarts, like it calls for. i let it sit for about 15 mins, and when i checked it, it was only halfway on the safe mark. I went read on some forums, and it says the hemi takes 7.5, sometimes 8 quarts, to reach the full mark. Should this be a cause for concern? Will it be safe with 7 or should i put another 1/2 qt?
