i was riding wit my dad and just casually looked at the piece of paper receipt shops give you after they work on your car. so this paper was from the penzoil shop and they did a recent oil change on my dads 03 accord...now hes got like 140k some miles...

i was a bit surprised to see they put 5w30 in his car..isnt that a bit light for the car with 140k miles??
is that weird?
