sn0man, 3.4 quarts without oil filter replacement and 3.8-4.0 quarts with oil filter replacement. Best thing to do, check your dipstick after you have the minimum amount in it, and ran the engine for a few minutes. Make sure that the oil level shows on the dipstick as your manual suggest. The other thing I always do, I prefill the oil filter with engine oil, this minimize the run time until the filter fills. Hope this helps, good luck.
