Default MPG issues

I have just joined InsightCentral and have been reading through many of the posts about fuel mileage. I, along with everyone else most likely bought the insight for the fuel ecomonmy and the cheaper cost compared to a Prius. I have only fueled up 1 times since buying and the MID showed 48 and when calculated was 44.66. This was mostly city and some urban backroads to get to work to avoid traffic. This backroad seems to keep my MPG up without needed to stop so much and being able to run at 45 mph. I took a trip to Wilmington NC using some highways but kept my speed at 50 instead of 55 and the rest of this tank is the same backroad. I know that the mid reads a little high which is ok with me, but right now its reading 54 even. I ordered a K&N air filter. And I know all the little tricks and have follwed them for a long time in my old truck with accelerating nice and coasting and the tires. But is there any modifications like computer chips or anything that are cost efficent to increase MPG without voiding warrenties. I bought a lifetime, yes lifetime warrenty from the local honda dealer for a good cost and don't want to void it. The warrenty information doesn't provide any clear information and I dont want to hurt it. Any MPG tips would be a great help.

Any "chips" offered will be for performance. Learn the hypermiler tricks before seeking any mods to improve mpg.
How much did the "Lifetime Warranty" cost. Read the fine print. To my knowledge, Honda doe not offer such a warranty.
Once the G2 gets broken in, around 4-5K miles, your mileage should improve. Welcome to the Forum.

I have been doing the hypermileage tricks like keeping the mph screen in the green as much as possible and traveling a slightly longer route to work because it offers better mpg. I bought my insight used with about 37000 miles so it is broken in. I just put in my K&N air filter today. Whether or not it gives me better mpg or not it is a must for all my vehicles. I am just trying to make my car get the best mileage possible. I get the lifetime warranty through the dealer. It is strictly though them, not Honda. It was $2000, but it covers everything but the basics like tires, brake pads, bulbs wipers and filters. Everything else is covered. I hope it works out but only times will tell but like I said it is strictly though the dealer. I'm just trying to make my car get optimum mileage through any means possible without spending to much up front. But this site has been great so far. Thanks

I saw a K&N filter a few years back and noticed it had very little filtration media compared to a Honda. Why would you want to let more dirt go through your engine?.

I've read the "down side" to K&N filters and in 2 past vehicles I have put brand new air filters in ran them and then replaced the OEM with a K&N. Both running 10,000 miles in the same conditions and the K&N was much dirtier once those 10,000 miles were up. From what I have noticed it not only took out more dirt from the air but with similar driving I did notice a slightly better MPG difference in both vehicles. Not much, and definitely not what they claim. However, with just the K&N air filter driving mostly red lights back and forth to work, 15 miles, and short trips across town with the same stop and go traffic my MID is reading 53.5 right now with 248 miles on this tank. I know the MID reads a little high and mine has been reading about 3 MPG high, but I think for now I'll stick with the K&N and I'm happy with the MPG. The only thing I'm concerned about is Honda telling me there OEM oil filters have a special seal on them and by putting other brands like K&N or Fram oil filters they may not seal causing them to leak or burn more oil. Has anyone tried this and noticed a burning off or leaking of oil? I dont know if I want to chance it but I think also Honda might say it to get people back in the shop. Also how often is everyone changing oil in their Gen II Inights in city driving?

I've only done 2 oil changes so far and I go by the trip computer - about 9K miles on Mobil 1 synthetic 0w20 oil. The first time I used a Mobil 1 filter, but I had lots of trouble taking it off, despite not really tightening it on and applying a film of new oil when I put it on. Maybe a one off or what not, but I've never had that problem before on my other cars and I often use Mobil1 filters on them... For the second oil change I bought an OEM Honda filter that comes with a washer in the package. Even from the dealer it was about 1/2 the cost of the Mobil 1 and looked just as hefty and of very similar construction. Will see if that comes off easy enough.

I typically go at least 10K miles each oil change on my other cars and sometimes 15K (if I use Euro-spec oil such as Mobil 0w40, which is supposed to be tougher than the US-spec regular Mobil 1 full sythetic).

Your mileage is decent and on par with what I would expect from your commute with a light foot on the gas and brakes. In my '11 Insight with about 20K miles on it I manage to hit high 50 to low 60 mpg on the display without much issues in smooth moving traffic (some A/C does not seem to affect mileage too much on the highway). As long as my trip is longer than 8 miles or so (warm-up takes a toll). But with lots of stop and go (heavy big city traffic) hitting just above 40 on the MID is all I can hope for. And if it is raining or hot and I need the A/C a lot, then just under 40mpg is the best I get in heavy stop and go.

I think it's more of a scare tactic than anything else. As long as you have them on tight enough and they are the correct diameter threads and gasket; all is good. To date I've used Honda Filters but in a day or two when I change my oil, I'm planning on using an Amsoil EAO 44 Filter. The Amsoil EAO 44 is like twice the size as the Honda but has the same thread pattern and gasket. In Bob the Oil Guys Forum, many folks have used this over sized filter on Civic's Fits and other Honda's. I guess I'll be the first to use it on an Insight.


As far as frequency of oil changes, I would go no less than 7,500 miles; no matter what the oil life monitor says.

It's a combination of the fact that the 0w20 is synthetic and since the Insight has cylinder deactivation a good portion of the time; the oil stays cleaner, longer.

At any given mileage our oil is cleaner than an non hybrid vehicle.

But doesn't the monitor take those things into account? Aren't there driving behaviors and ambient conditions monitored by the ECU that could cause the oil to get "dirty" sooner than 7500 mi.? Why shouldn't we trust the oil life monitor? Why did you choose 7500 mi. as the minimum?
