5 quarts with filter is the fill. I use 30 wt Quaker State and a Fram or AC filter.Oil is a personal choice.Use what you feel is best,and change it on a regular basis.I personally do not use synthetcs as I'm a strong beliver in a 3 month/3000 mile oil change,and my opinion is that synthetic is too expensive to change it that often.My 2 daily drivers have 142,000 and 134,000 miles on them and I've always changed the oil and filter on a 3/3000 schedule.Hope this helps.
