Just did my first engine oil and filter change. The owners manual says 3.7 qts but I've got 4 qts in it now and still barely at the halfway point on dipstick. After replacing oil and filter, I started it and let it run for a couple mins and checked again and again after letting it rest with same results. So is the manual off or is it me? And what oil is everyone running in there front axle, sudt2 or gear oil? Thanks
