When I'm faced with these odd-ball fill amounts: 4 1/8 quarts, 3 5/8 quarts and so on, I simply take an empty, but sturdy plastic gallon jug and mark it up with the correct file lines. You can even get about 4 1/2 quarts in some 4-quart windshield washer jugs. I clean it very good, and then start filling it with 1/4, 1/2, 3/4, 1 quart, 2 quart, etc amounts of water. And the wife actually doesn't mind as long as I use water instead of oil in her kitchen measuring bowels while doing this. Then mark the levels I need on the outside, and use the clean, premeasured jug for changing the oil next time. I have four of these for 4 different vehicles. Pouring exactly 3 5/8 quarts of oil out of a container is a hell of a lot easier then guessing how much has come out of a 5 quart pail, risking overfilling, and then having to open the drain bolt...again. Once the fresh oil circulates, the dip stick is always filled to the mark. And its on the mark, everytime! On vehicles that take 5 1/2 quarts, I just use the 1/2 quart line and a full 5 quart jug.
