Are you saying that you’ve now gone 13,000 miles on the oil that’s in the engine? If so, I would be more concerned about that than the weight of the oil. ---

Did you leave the 10w40 in the engine for 13,000 miles without changing it? ---

10w40 is a heavier oil than 5w30, and could give slightly accelerated wear, but it seems like that’s not your biggest problem. It sounds like you haven’t changed your oil in 13,000 miles. Even the correct weight oil is going to have problems going that far. I would have changed the oil in my car 3 times over that period. You should check for sludging, among other things. ---

I agree with the others. The weight of the oil for that amount of time should not have caused any damage, although you should use the correct oil in the future. However, going 13,000 miles without an oil change is a problem. You should change your oil more often. I recommend every 5,000 miles ---

Somewhere there is a temp range chart for motor oils. You’re fine.
