I have an F-53 chassis and the oil filler tube is too high and in an awkward location. I tried using a screw-on plastic hose on a one quart oil container, but that took much too long. The last time I changed oil, I bought the oil in five quart containers and poured the oil into a one quart oil container with the small diameter opening. I was careful not to overfill the quart container and was able to pour the oil into the filler tube without spilling a drop. Filling the quart oil container was easy because I used a funnel.
