This will go down on my permanent record...

There is a term for this. Data for data sake.
Collect data for no known reason.

 

The safety wire seems like a good idea.
The hard part is going to be finding a place that will accept used oil at all. In the past, most auto parts places would take it. Now most seem to not do that.

 

Good on the valve and EXCELLENT on the safety anchor. Oughta be a 11 gallon can for people that change their own oil, like the 2 story mobile home for those with money. Jus saying...

 

Back in the day, we’d pour-the stuff old a gallon at a time into the fuel tanks.

 

Up in cold weather country my auto shop on the corner takes mine for his shop heater... do you run any cold country routes?

 

Times change...
Used to be 2 execs would say: "Have you girl call my girl and we will do lunch."
Now it is: " Have your computer call my computer and we will do data."

 

A little "upper cylinder lube" kinda thing.

 

I had one for a while. Always worried about it getting hit, and draining my oil. Like You, thought about different ways to secure handle just in case. I accidentally forced it the wrong way. The locking effects not very good now. Not easy to ruin it, but I managed to. Took it off, yet to get another. They’re great, makes the job much cleaner. Poking a hole in bottom oil filters, with a screwdriver letting them drain first helps too. I always make sure they’re gonna come off first, with the filter wrench, just in case ones stuck on for some reason. Always refill oil filters before putting on. I like having the magnet on the drain plug. My version of an oil sample. Think I’ll just keep it that way. I have a small ball valve plumbed into my bottom radiator hose. It’s handy, for draining the coolant for any reason, especially for unexpected reason, or flushing the system. I’ve used it quite a bit. 1/4” turn brass ball valve. No zip tie, or latch lock. I should put something on it, to keep it closed, in case it gets hit by road hazard.
