As you see, the Hybrid dipstick is pretty tucked away. Sorry I didn't know the standard Tahoe/Yukon was so high and visible.
Wow, did not know you had a Hybrid and your right that tube is low, real low. Not sure if painting the "TUBE" or the "dipstick" would help in that situation. I had to actually look quite a bit to find it in the picture you have posted.
I would honestly, look into some sort of lighting, as myself and Ezdaar have posted. Maybe you could put the lights lower for more visible light down lower. Possibly allowing you to see the tube inorder to put the stick back in.
Or I wonder if you could extend that tube more so that it was protruding more and not so tucked away.
