I made a 3/4" pvc extension using 2 90 degree elbow and some pipe. The stubs are long enough that they cannot pop out of fill tube and I use funnel on inlet. No issue no mess easy job. I think it is 30+ inches long. I just changed oil day before yesterday. The oIL fill is right behind A/C lines in passenger side valve cover.
If I had to add oil on the road, I would use gear oil nozzle from gear oil jug and squirt it down dipstick tube. I carry a spare nozzle and have one setup for generator oil.
