The benefits of synthetic oil for us Canadians can be felt in winter, especially for those of us who torture our cars by leaving them out in the cold overnight. Synthetic doesn't "thicken up" in cold weather, making cold starts easier. Also, synthetic doesn't breakdown chemically, like regular oil, and will last longer and not harm your engine. However, synthetic still gets dirty, and your oil filter still gets dirty. I change mine every 5,000 kms or so... You can just change the filter, but, your there so why not do the whole job.
