Regular oil changes DO make a difference.

I think a lot of people believe that modern oils mean they can neglect their oil change interval on their cars. Too many products advertise "lifetime" guarantees, and 20,000 mile oil changes. I've seen plenty of engines that have been ruined by poor oil change discipline. The photos below were sent to me by a reader who was doing a cam swap. They show a pair of Hyundai Coupe engines. The older engine is in much better condition internally because the owner changed the oil regularly. The newer engine was owned by someone who either didn't care, or just couldn't be bothered.
Oil changes: cheap insurance for your engine. Just do it.
