New MPG record!
 

I didn't try too hard for this, but I did keep my speed right around 58-61. A couple times I dipped into the low 50's but not for long.

Also, I finally got a newer battery. Car background charges A LOT less and I have sooo much more battery.

Also, my first 70mpg tank!!

What I ended up with by the time I got home (had to do a 40 mile excursion across town so it might have been higher).

What car is it?

1 gen insight.

Nice job Balto.

Was your 90+ trip on completely level ground, or was there elevation change? Regardless, congrats on the 70 tank.

Downhill. I think somewhere of a 2000ft elevation drop over 70 miles with some uphills. 6% grade over 10 miles though (roughly).

Thanks guys, I still don't have any underbelly panels and my front end is still tweaked up. I have a feeling that would have been triple digit MPG's if my front end wasn't so tweaked up/missing panels.

Not bad, not bad at all!

Guess I'm gonna have to step up my game and try to squeeze a little more out of mine with all you guys creeping up and passing me. . . .
Man, if you lived near central Florida I'd hook you up with some pallet liners for your lower aero panels, but that's a long haul!

cowmeat's panels are no joke. They're tough as hell and just the right size. If I could haul more with me up to the northeast, I would.

Anyway, it seems like you'd only be chasing a few percent. You're already doing pretty darn well.

I already have access to panels, problem is, my entire front end is pushed up and in on the passengers side. I have to get it on the frame machine and pull it back into place, just haven't had time to do it. I tried putting a panel on it last week, but it doesn't line up by more than 5 inches.

Today I only got 70.2 going to work. 30mph headwinds are not nice to my MPG's :((((.

Sweet!

You still have to hook me up with some. My car looks pretty empty underneath.

Awesome job, Balto. I was shooting for 70+, but I don't think I'm gonna make it with this tank. It's slightly going up on the FCD, though. It went all the way down to 67.2 last week, so I don't really have high hopes for this tank. I've got a third of a tank left, though, and it was at 68.8 when I pulled into work this morning. I need to get at least 72.5 on the FCD to get a tank above 70, so that's what I'm shooting for. Obviously not with this tank.

We're both going to have to step it up! Your brother is sitting at around 75 mpg on his FCD and rising @ over 450 miles on this tank. I ended up at right around 69 mpg this tank with my FCD showing 71.9 mpg, the last two tanks it has been off right at 3 mpg to the high side.

I bet they aren't 2 bucks apiece, lol!

His trip to work is all highway miles. I don't think I could beat that if I tried. Plus that three story parking garage at the end of my commute doesn't really help, either. That's pretty awesome, though. He'll definitely wipe the floor with my mileage on the next fill-up. I'm still at 68.8 on the FCD, and on the low side of it, bouncing back and forth between 68.8 and 68.6.

I was looking over the service manual, and supposedly it's recommended that you fill up with 91 octane.

Nope, free! :P

My commute is all freeway, and I drive the Mustang around town. I do have 7 miles of city driving right at the beginning of my commute , with 3 miles at the end so yea. The insight never sees city otherwise.

I've tried premium 93, mid grade 91, ethanol-free 87, etc . . . . in the Festiva and in both Insights. I have never had a noticeable gain in fuel economy in any of the cases, just paid more at the pump.

I am curious as to what gas everybody uses in their Insights, though.

I run 87. Same in the Mustang, 87. Makes no difference unless your running FI or crazy NA horsepower.

I tried higher and saw no improvement. Perhaps the "91" in the manual is not AKI?

91 RON = 87 AKI

Octane rating - Wikipedia, the free encyclopedia

Why would it help FE? All higher octane does is prevent detonation. If your insight is detonating with 87,please seek help for your car.

Many newer vehicles will advance timing if they detect higher octane fuel.

My best tank was 73.5mpg in a 01 CVT non-leanburn Insight. Last summer i didn't have a tank below 70mpg. I live in a really hilly area too. If you guys try as hard as i did to get 73.5, you can blow me out of the water!

Of course i have a 3 mile commute now. My current tank fcd display from the winter is so low i'm ashamed to say.

Sheepdog,

What methods are you using that have the biggest effect in getting that kind of mpgs? I'm always looking for pointers to increase my mileage! Right now I've kind of leveled off a little under 70 mpg in Ron Burgundy, and of course I'm wanting go increase from there.

I haven't modded this car at all so far, but I plan on adding the three-button shifter and a full belly pan if I ever get a free weekend.

Good luck at Watkins Glen, man!

Turn off your AC and keep it under 55mph. Avoid the city cycle. My old commute was 20 miles one way. If you have to 58mph is ok. But that is just for my non-leanburn car. If you did that you would get over 80mpg i would think. All i've done was just drive with load with the engine always on, and the windows rolled up over 35mph. Only mod was a partial grill block.

I have no intention to be a teaser, I just found this thread in the Ecomodder newsletter and a few hour earlier i set a new personal record that made me both proud and slightly shocked. -My 40 year old Saab 96 got 4,3 l/100km (=66 mpg) today! -And that's a mix of 80% highway and 20% through the heart of Stockholm, the capitol of Sweden.

The Saab has a V4 1500cc carburetted stock engine with 4-speed gearbox. No engine mods, no aeromods, just efficient driving! :) Well... I have been around 4,7-5 L100 (56-60 mpg) for some time now, but that dropped even lower, probably with some help from the 7% larger front tyres (225/70/15").

The big magic is a more and more extreme use of the P&G, or as I prefer to call it, Burn & Glide driving. These old saabs have a gearbox freewheel, a rather amazing little device that makes shifting gear and engine on/off a lot easier. I have done this B&G for over a year now and the starter don't show any signs of wearing out yet. Obviously I'm getting quite skilled with the driving style. :D

The way I perform the B&G, (B&C, P&G or whatever names they call it) I accelrate with about 80% throttle to 85 km/h (53mph), turn the engine off, glide down to 60-70 km/h (35-45 mph) and repeat the cycle over and over again as long as the traffic allows me to. In city traffic I just give the car a litte push and shut down the engine again. City traffic can actually be a helper to keep fuel consumption low, but you realy have to work hard for it.

By practising B&G you get a lot more observant and skilled at planning your driving. You look a lot wider and also think way beyond normal driver's capacity in the stressive city traffic. Even though I somtimes keep an annoyingly low pace I often pass by the heated BMW-people after a few traffic lights, sometimes more than once. I just love their faces! :D

in December last year, the job car is not working. He is missing car at work. I started to use my car to work.

at work they are often short trips and the engine is cold. most days it's cold winter and at night. making it necessary to put the lights, fan and heated rear window.

now it is not cold. night is only part of the time.

to start using the car to work. climbed fuel consumption.

I made a modification. change tires 195 / 55R15 to 175 / 65R14 (origuinal measure). I put the tires covers.

at first start working consumption was 6.5 l / 100 (36 MPG US) . consumption is the work and private use.

consumption before leaving to use the car for work was 5.7 l / 100km (41 MPG US)

without using the car to work. since early May.

the last consumption was 4.3 l / 100km (54 mpg US). this is the consumption lower than I succeeded.

I think some things influenced the consumption.

Winter consume more. to put more lights. fan. Heated rear.

changing tires for a more narrow. and lighter. takes some of consumption.

the most important fact. how to drive. putting the longest speeds. accelerating treading the 80/100% throttle. if possible by the traffic. coming more slowly to traffic lights and stop.

I'm doing the same thing on the motorbike. but with worse results.
