Winter driving is the hardest on an engine so by doing an oil change is a good thing as long as the filter is changed as well.
I use Castrol oil products on all of my cars and change the oil/filter every 6,000 miles or 12 months whichever comes first. One of my favourites now has 346,879 miles on it covered over 20 years. My real favourite has 34,519 miles covered and its 26 years old.
