Will 10w-30 motor oil instead of 5w-20 damage my V6 2008 Honda Accord?
I added a quart of 10w-30 motor oil instead of the recommended 5w-20 to my V6 2008 Honda Accord. Will this damage my engine? The car has approximately 5,400 miles on it and 50% oil life remaining. Also if you go a little beyond the top of the fill line will that result in engine damage? Thank you for any advice you can provide.
