My 2000 Insight 5-speed is currently in the shop due to a variety of issues. The biggest reason I bought the Insight was gas mileage, as I live in L.A. When I bought the vehicle it had a lifetime mileage of 44.5 with only 38k miles. I am the 2nd owner. The best I've seen out of the car is 55 mpg, the worst was 32 mpg, which my old lil' baby car 1990 Honda Civic Hatchback Dx did better! I've read over a lot of the responses to low mileage, and I have to say I don't abusively drive my car. I like to drive fast when I can, but living in L.A. that's rare (and fast is 80 tops). I drive a good mix of city and hwy with the occasional road trip thrown in. I've always driven 5-speeds, even so I had to "relearn" how to drive this car based on how good of gas mileage I'm trying to coax out of it. I don't know what my tires are inflated to, but you can bet I'll pump them up to at least 40 psi. I've had my car in numerous times because of this. No one at honda's service departments seems to know anything. I've had the regular battery replaced, the electric battery replaced, and now who knows what else. I am both excited and infuriated to see that others have had the same problem as I and have not been able to get a straight answer out of Honda. I'm going to continue to read up on this site and others but any comments/ suggestions would be useful. Thank you!!
