Additives are not neccessarilly a bad thing people. I put z-max in my engine at about 92,000 and i notice a huge difference in acceleration and gas mileage. Yeah it's expensive, but I think it was worth it. Also, Restore oil additive is a godsend, after about 50 miles you can really tell your car is pulling a shitload more, at least mine does. It usually takes my mom's explorer about 150 to really tell the difference. Another thing is about the oil changes are alot more important than you make it sound. Using the same oil for that long in city driving puts alot more wear and strain on your engine than it needs. I drive for a living and so I probably have a lot more time to think about these things than i should, but it is my life.
