Ok, I've heard, and to continue to hear here that I should just change it every 3k to be safe. But with all the technology on these cars that do everything else, why won't this work?
Just imagine the environmental impact of every car in america running 4, 5, or 6k between changes instead of 3. I meen my dad says he's changed his oil every 3k for 30 years. Is there even a possibiliy that this may work?
