I just bought the nicest newest car I've ever owned. I'm very happy with my new (2000) Insight. I wonder if I should maybe be getting higher than 50-60 mpg on the highway? I see people boasting 70 + and I only got 66 mpg for a short time of freeway driving on the way home from my first oil change. I tried getting the service records from the dealership I bought it from, and they seem to have taken my money and run. I just want to make sure that I'm not hurting it by driving it when something is wrong. It has over 90,000 miles. Advice? Tips? Im exploring this website as much as possible, but don't know that I could ever read everything with my schedule.
