I used 10w40 (M1 full synthetic HM) in my last oil change when the car specs 5w30. I have been doing my best to not worry about this (it's probably no big deal) but I still do.
What do you guys think. Is this no big deal. The car is a 4cyl with 111,500 miles. I live in North Central Washington and although we have snowy winters our average temp is around 30deg F. Occasionally we will see 10deg F. but not often at all. Is this a cold enough climate to worry about not having (5W) oil? Is the 10w40 to thick for this situation.
I don't care about swapping it out but would I be doing it for no reason. (I have 800 miles on this OCI)
