I have the same issue, to the point of insanity! I didn't know to 'measure out' what I drained when I first did a spill and fill years ago, and to this day I am not really sure where the "HOT" level falls on this stick. Obv all is well, as that first drain was 100K miles ago, with repeats every year, but still -- if the damn stick is there, I want to read it!! I am thinking about lightly scoring the stick w a file or emery paper in the hope it will provide a sharper view. I wish Toyota had gone w holes here, but I am not about to drill my own.
I once had a job climbing fuel storage tanks and taking level readings from access ports on top; we had a metal tape on a spool similar to a fly rod, with the same kind of crank handle. I let out the line and the plumb would hit bottom (sometimes 40 feet or more from where I was at the top) to give me a 'rough idea' measurement. I would then crank the tape back up and use a special 'cut paste', applying it about a foot either side of the 'rough' measurement. The fun part was then lowering the plumb to about the general area again, this time very slowly, really feeling for it bottoming out and stopping. Onretrieving the tape, the 'cut line' on the paste was very easy to see, and also remained in place with thin fuels like AvJet.
My point is: it shouldn't be easier to get an accurate measure from a multi-thousand-barrel fuel tank 50 feet high at 2 AM and 10 degrees then a 2002 minivan in my driveway LOL!! OK, old guy rant over.
