Tom Denison's trick for putting oil in the engine (instead of on it)
Here's what I came up with for adding oil to my CJ. As you know, the oil fill is in an inconvenient location under the gas tank. I used an empty gear oil squeeze bottle that I filled with motor oil.
As you can see, it's an easy, no-mess way to top off your crankcase. No need to make room in my saddlebag for a funnel when I'm on the road either.
