I can take a digital photo if it would help, but I've noticed that on the part of the dipstick that you read, it has grind marks running horizontally, at about the halfway mark. Is this normal? I noticed it quite a while ago, van has 100,000 miles on it now but first noticed this at about 60k miles. It hasn't gotten any worse, but always seems to look "fresh" when inspecting oil level.
