I bought the oil temperature dipstick. Twisting it in is fine, but I love symmetry and the numbers don't sit correctly (with the "f" at the bottom). The instructions say to grip the needle (I assume that's the long part that sits in the oil) and twist to put the 200* at the top of the housing. However, doing that affects where the temp needle starts - as I twist the needle, it's obvious that the temp needle is attached to it and the two rotate together, defeating the purpose. I feel that I'm following the instructions, but I have to choose between having the reading skewed or having the numbers be "sideways". What am I doing wrong?
