It takes about 5qts, first pour in 4 qts and then warm up and fill to mark. Do not over fill. It's a bit messy as there is no drain plug. Remove all the bolt but the front two. Loosen them up so the pan will drop and catch the oil in a large oil pan. Depending if you have a 4x4 pan or a 2wd pan there are different flat filters and a spin-on filter. Use care installing the flat filter, installing the rubber grommet first and then the filter. If not done properly you may well have a air leak causing issues. Good luck..
