My scion XA's plastic dipstick is literally the same color as motor oil. almost impossible to read unless the lighting is just perfect. I also have a 99 Saab in which the dipstick has a black plastic ball at the end. I guess if the plastic ball area is wet the oil level is fine but very difficult to see motor oil on a black surface. Wish dipsticks were white or similar contrasting color to make reading oil level easier. Yes, I'm getting older and visions not what it use to be
