is 5000 miles too long to wait for an oil change?

5000 miles on an oil change, it depends on how much you love your car. Yes todays engines are better built then long ago, I was a mechanic then and still am. I also worked in an oil testing facility in the military. There is more break down of the oil the longer you use it, except synthetic oil. Toyota does not make any money from you by having engines last 500,000 miles. They want the engines to wear out sooner so they make more money. I did my first oil change on my "S" liftback at 1800 miles and my routine oil changes are at 2500 miles. Oil is cheap,engine work is not. Yes, you believe what you want to. Our 1.5 is a small motor that works hard and makes alot of heat. I have tested oil for many engines in a lab environment. Its science, not speculation.
