It seems to be strange to open up a thread of the worst milage on an Insight, but keep in mind that for a lot of people it could be great mpg.

My worst ever mpg was on December 15, 2000 when work was closed early so people could go home before the roads iced up. It was not soon enough. I was going 30-40 mph the first 30 minutes. After that, the ice and sleet turned all the roads into a stop-an-go parking lot going at 2-3 mph. The rest of the trip was four hours. Over 30 miles, I got 25 mpg. The defroster prevented autostop from working.

I don't remember the specifics but during last winter in New England I had several sub-30-mpg days. Thanksgiving we drove to New York in the snow and got around 30mpg round trip. Stop and go traffic, temperature around 20F and no idle stop.

Took a trip from Fla to North GA wide open with AC on. I say wide open at never less than 80mph average speed was 90. MPG for the trip was around 45.

Looks like you guys in the cold weather and bad roads will have he worst.

My worst mileage was with the thermostat stuck partly open in the winter with temps in the single digits for a bunch of short trips. I averaged only 35 for about 100 miles total of city driving.

Excluding mechanical failure my worst mileage was while rushing catching a plane in the dead of winter, I averaged only 60MPG for about 50 miles of 60MPH to 95MPH driving but I caught my plane.

Winter blend ethanol didn't help either case.

I think my worst mileage ever was going from Phoenix to Tuscon. I was moving too as fast as I could in 5th without using any assist. I think I must have averaged 85mph if not closer to 90. AC was on econ the whole way set to about 78 with the fan manually set and it was very hot out and I don't recall feeling the compressor cycle off very much. I still got about 48mpg for that trip. I guess I whine a little about the extreme heat being a mileage killer when in fact I guess the extreme cold it worse.

16.1 MPG during the .7 mile long autox course this weekend. I may have been the slowest vehicle out there, but I was the most technologically advanced !!!

My worst ever one tank milage was 58.9 for 679.6 miles. We had just got the car and had not figured out how to drive it yet. We were using A/C, and driving fast, and went from Phoenix (1000 ft) to Springervill (7000 ft).
Yesterday I filled up in Tucson (2500 ft) and drove home to Phoenix very carefully. My mpg after 94 miles was 109.7. Today I drove to work and back plus lunch all in the rain and now my mpg is 96.8 after 162.2 miles. I was hoping to set a personal record of over 92.1 for a tank, but with winter gas, colder weather, and new tires, it will be pretty hard.
Still trying; Louis

Right now I've been getting in the mid to high 50's on a 5-speed Insight. Based on the various postings I've review, mileage gets bad in cold weather, so I'm assuming my experience is "normal" (temps here in PA have been in the 40s).

Can anyone tell me what's "normal" for break-in for these cars? I've never attained the 68 mpg highway claimed by the EPA or the phenomenal milage I see posted on this site. Best I've done is 65 mpg.

Yes, I'm on top of the tire-pressure issues. No, I'm not a "go slow" driver-- I pretty much stick with the traffic (65 to 75 mph highway).

How long have you had the car? I have had mine for a year and a half. This summer on a round trip to Kingston I achieved 87 MPG. Last week with high winds and sub zero temps I achieved 67. Check this link for winter tips.

All cars do worse in the winter. The good news happens in the spring when gas mileage goes steadily up. :)

We get quite the opposite here in the southern US. When the air conditioning shuts off mileage goes up. :wink:

Thanks for your reply. I currently have about 3,000 mi (4,900 km) on the car and have owned it since August. I know mpg improves over time as the vehicle breaks in-- my question is, "how long?". Should I be concerned or is my mpg experience "normal"?

How do you manage to get such impressive mileage figures?

My lifetime MPG was about 48 and 52,000 miles later is 56.1. It would be tempting to reset the lifetime MPG because over the last six months it would be lower to mid-60s. It's taken awhile to learn some techniques.
