    Any hyper milers out there in Foo land

    I've just started using a few techniques to increase the fuel efficiency of my 2012 Honda Civic, now hybrid model. I have been shifting into neutral with my automatic transmission and letting it idle in neutral at red lights, in economy mode I was averaging about 36 miles per gallon for my daily driving which is a mix of highway and city driving. This tank is closer to 37.5 to 38 miles per gallon. I think that's a pretty good increase. Any other techniques that you use while driving your daily driver?

    I chipped the ECU in my Alfa 33 gaining loads more power and slightly improving fuel consumption to 5.9 litres per 100km's or 38.9 MPG

    I started taking my foot off the gas when going downhill. It made about a 2 mile/gallon difference when I drove a Highlander. I now have a Prius which is much more aerodynamic so I can coast quite a bit longer before stepping on the gas.

    I replaced my 4 cylinder manual with a 6 cylinder automatic reducing my MPG from 38 to 21.

    With a prius, I'm not sure one can even tell when the gas pedal is mashed.

    My 20 year old Sentra still runs rather well and I always shift into neutral at stop lights and try to keep my foot off the gas as pressing it down harder does not make the car go that much faster anyways...

    I can pull 40 mpg on the highway if I pootle and city mileage is really variable... it depends on traffic conditions and being able to anticipate stops and not racing from stoplight to stoplight makes a world of difference. High 20's to low 30's are pretty normal and when I am in the city I get better mileage on my bike.

    A new car in same class would get slightly better mileage but come with a payment... "Sunny" only cost me $1.00 and over the past couple of years I haven't put more than 1k into the car for work and have driven 40,000 trouble free km.

    I have a long commute and in traded in my v6 toyota for a 2011 VW Jetta TDI with a 6 speed manual. I use no additives and according to the car's calculations, average in between 45-46mpg per tank. I have put 92,000 miles on it since new. I have a soft touch and can squeeze out better mileage if I try. I did try running the tires at a slightly higher pressure than recommended and that was fine until it rained. Traction was much better in the wet when I dropped the pressures back down. My best tank was an indicated 52.5mpg on a road trip.
    My tips:
    - Shift into neutral and coast down to lights as often as you can. You don't need to coast down hills but I have done it a good bit and it works.
    - Never idle more than you have to as you get ZERO mpg while idling. I don't mean turning you car off at lights, but minimal warmup and shut the car off immediately when you have arrived at your destination. That being said, I do idle for a minute to help cool the turbo before turning the car off if I have driven on the highway and stopping at a rest stop.
    - Draft when safe to do so. Any draft at speeds over 20 mph will up your mpg.
    - Keep the car clean. I know it is not much but mud and crap all over the car does not help mpg
    - Ditch all the crap in your trunk that you do not need. The extra weight adds up.

    Good luck!

    I have drafted tractor trailers on road trips and while maintaining a safe distance saw some pretty massive improvements in mileage... the urge for most would be to pass but when you do this for hours on long trips the car's energy use drops down considerably.

    I put a ScanGauge II on my Kia Spectra5. Watching the gas mileage in near real time saves me a lot of gas.

    I noticed that a new set of tires reduced mileage by about 1 mpg. Hopefully things get better as the tread wears away.

    Putting the automatic transmission in neutral while stopped at a light saves about .05 gallons per hour and used about 1.5 horsepower less at idle.

    I'm pretty good at timing traffic lights on my commute to/from work.

    I'm in the "lowest rpm, highest possible gear that doesn't lug the engine" school. Some cars like this better than others.

    If I didn't live in an area where other drivers would cut your throat for ten seconds of time and a carlength of space, my hypermiling would be more serious.

    My Sentra has an automatic with overdrive that will kick in at 35 - 40 kmh... if I switch that off the car gets a lot zippier but the mileage suffers as my foot seems to get heavier.



    My last Sentra was an '89 hatchback with a sewing machine engine under the hood... it had 30 less horsepower (same displacement as the current Sentra) and a 5 speed and would get 50mpg on the highway.

    My 250 Suzuki motorcycle gets 70-75 mpg. I don't push it too hard, but I don't take any extra measures to increase the already heroic mpg's.

    My golf cart will go 25-30 miles on a charge. I don't know what it costs per re-charge, but running it about 10 times a month did not make a difference I could see in my heroic power bill, which runs about $40 a month.

    ($24 was the best power bill I ever got, one mild February; the first $12 is a "Thanks for being our customer" charge, so $12 worth of juice..)

    So, I'm just hyper-cheap.

    My wife's PT Cruiser likewise. I steadily accelerate to the overdrive's tip-in and set the cruise control just a bit higher, traffic permitting. Manual transmissions are a lot more fun, though. And lower in the parasitic drag that lowers fuel efficiency.

    Stay out of left lane. It is really frustrating getting stuck behind someone chugging along in fast lane, parallel to the car to the right effectively playing rolling road block, or taking two blocks to accelerate to a pathetic speed limit of 35. God forbid it is actually higher.
    I see hills.... Bring them on!!!

    With just normal driving, I get about 47-48 mpg on my 15 mile highway commute, with a 2011 Prius. By the end of the commute, the dash display is usually right at 50-51 mpg, but it usually overstates the mileage by a few mpg. That's mostly at 60-65 mph. It's worse in winter--at 30F the commute is about 44-45 mpg. So, maybe 2/3 of a gallon for a 30 mile round trip.

    If I'm stuck in stop-and-go rush hour traffic, with a typical top speed around 35 mph, and a bunch of complete stops, I get 58-60 mpg. The engine shuts off anytime I take my foot off the gas, and it does the 5 mph slow crawls on battery power. Even the A/C is electric powered.

    And my bike fits in the back without taking off the front wheel.

    Hypermiling is for you city rats and flatlanders

    We live out in the middle of nowhere and it is all up and down hills, nothing flat whatsoever. My 20 mile work route would be 1687 feet of elevation climb into work and 2161 feet on the way home (I don't commute, this is by car. No way I'd be able to do that on my old junk Walmart bike.) Thus, the actual elevation change between work and home is 474 feet. That gives you an idea of how up and down the hills are.

    My experience is, my wife drove a Mazda Tribute, EPA 17 city and 21 highway. For the first 3 years we owned it, she was stay-at-home and pretty much only drove to the grocery store every 2 weeks along with taking the kids to doctor appointments and the occasional family run to the mall. Like I said, we live in the middle of nowhere, every time we get in a vehicle it is pretty much at least a 30 mile drive other than my work commute.

    She was averaging 18-19 mpg for those 3 years. During that time, my billion mile car broke down a few times and I took the Mazda to work for weeks at a time. When I drove it, the gas mileage went up to about 21 mpg.

    For the last 3 years we owned it, she went back to work 29 miles I think each way. She now puts about 25-30,000 miles on a year and now driving almost every day plus still doing her grocery shopping now once a week since there is a paycheck every week and her driving had become far more aggressive than it was. Those 3 years she consistently averaged 21-22 mpg. I was filling the tank up twice a week with how much she was driving.

    I am the same way with my car. I drive a Jetta with the 1.8L turbo and I love the thing and use that turbo. I am very aggressive with speed and acceleration and I average at the EPA highway rating of 28. Again, this isn't ideal flatland cruise control interstate driving. It is constant up and down hills.

    I attribute the better economy with aggressive driving with the fact that a lot of the folks I see sticking with the speed limit on the downhills and then having to hold 3/4 throttle to try to hold the speed limit heading up the hills. I an I notice my wife as well drive faster than the speed limit and the momentum carries up the hill so that we are a lot lighter on the throttle. If I'm entering the valley of a hill at 65-70 mph, I'm not trying to maintain that 65-70 mph back up the next hill. I'm sitting on about 1/4 throttle and I'm slowing down heading up the hill but not dropping below the 55 mph limit while others are trying to hold that 55 mph starting out at 55 mph.

    Car #3 is a Toyota Rav4, 269 hp of 0-60 mph in 6.1 seconds fire breathing bliss, LOL. It replaced the Mazda last winter. Wifey is driving it and she really loves the 265 hp, LOL. Again, the EPA highway rating is 26 mpg (only 1 mpg less than the "economical" underpowered for a vehicle of this weight) and she is averaging 26-27 mpg out of it consistently. I've got plenty of data on that since we bought it the end of last February with 29,000 on it and now have 55,000 on it. That's 26,000 miles and we still have over a month before it will be 1 year.

    So you folks can have your hypermiling. I stick with my aggressive driving and get better gas mileage
    Ride no faster than your Guardian Angel can fly!

    My Honda came equipped with a real time mpg display, it's pretty accurate to, I check it by keeping track of how many gallons i Put in at each fill up and dividing it by the number of miles driven, it's accurate +/- .5 gallons

    My old SAAB 96 was a V4 (Taunus-Ford) 4 stroke , but retained the Trans-axle from the 2 stroke,

    and so It had a centrifugal clutch bearing on the Output.. the freewheel bearing
    let me motor up the hills , then coast down-slope at an Idle ,
    until coming to the up-slope again. when the momentum dropped to put the foot back in and ,
    still in 4th , power back up the next hill ..
    30 mpg easy to achieve and this was a simple carburator engine .. made 46 years ago..

    Clutches lasted a long time, too, because starting from a dead-stop,
    into 1st, is the only time it was Needed.

    I wasn't sure you could draft *and* maintain a safe distance. A coworker said he can draft w/ his Camry (Corolla? mid-90s anyway) and push mpgs from 35 to 50.

    I bought my car so I could drive back and forth between here and Portland Oregon (1000 miles) and enjoy trips to the west coast so I know what hills and mountain passes are all about, with a meager 120 hp under the hood you pretty much do the speed limit on long climbs and on some, like the Coquihalla summit you get to keep the truckers company.

    It all works out pretty well as what goes up must come down and this was a good way to see how much mileage I could get out of a car that has 260,000 km on the odometer and it is still as good or better than the factory ratings. For a fwd sedan it also handles rather well so you don't have to pause in the corners on the way down.

    It was nice to cross the Washington desert at 70 mph with Hank Williams playing on the stereo and still be getting mileage in the mid 30's... the best mileage does come at 55 mph / 90 kmh as then it can get pretty close to 40.

    Going from Portland to the Oregon coast (and back) I saw 38 mpg when I was pushing things a t***** hard through the winding back roads... I have owned higher performance cars but it is sometimes more fun to push a car to it's limit rather than drive a car like a Porsche where it is hard to find roads that present any challenge.

    My Thunderbird Turbo - Coupe was one of my favourite cars... the 2.3 turbo charged 4 would run with V8's off the line and the car got astounding mileage with it's 190 hp engine, cornered like it was on rails, and had every creature comfort. It is nice to see that Ford has come back to the idea of using turbo-chargers to improve the performance and economy of their vehicles after dropping it in favour of the less expensive V8 / V6 options.

    For my mid life crisis I'd like a Saab 99 Turbo...

    It does pretty well if you put it in all-gas Power mode, which I use when getting on the freeway. It's kind of fun to surprise other drivers who aren't used to seeing a Prius with any acceleration.

    I wasn't sure of that either until I tried it, at a safe following distance you still benefit and need to be mindful to stay out of their blind spots.

    It is a more pronounced effect when you are on a motorcycle and are trailing or passing a tractor trailer... it is more like a slingshot.
