I own a 1998 Honda Civic EX Sedan. It has 160,000 miles on it. I recent
got an oil change on it.

During the life of the car, I have used 5W-30 motor oil. However, some of
the mechanics at my oil change place have said that I should switch to
10W-30, due to the mileage on my car, and because 10W-30 is thicker.

Should I take heed to this advice?
