I’m a mechanic and struggling with this as well . The dip tube tube is a bad design .I have been struggling to read the Dipstick since I got my truck. I have the Cable style dipstick. I can see oil about 1/4-1/2 then there is oil at the very top and all the way up the cable portion of the dipstick. Its impossible to read. Any other dipsticks that are easier to read like the old 7.3L?
