100 Miles Per Gallon? Hypermilers Do It All The Time
usatoday.com — Hypermilers practice such unorthodox techniques as coasting for blocks with their car's engine turned off, driving far below speed limits on the freeway, pumping up tire pressure far beyond car and tire makers' recommendations and carefully manipulating the gas pedal to avoid fuel-burning excess.

- S7aind, on 06/25/2008, -7/+7Time is money, so is it worth it to drive super slow to save a few dollars here and there?

- sgiffy, on 06/25/2008, -3/+26Not to mention that shutting off your engine while driving, especially if you have power steering, is rather dangerous.
- sladek, on 06/25/2008, -6/+3especially if you have an old diesel and have to wait for the glow-plugs to heat up before firing the engine
- BLKMGK, on 06/25/2008, -0/+8A warmed up diesel doesn't require glow plug warmup to restart or start at all in warm weather. So long as compression is good and the fuel isn't jelly it's not a problem.
- SmokeN-DC, on 06/25/2008, -2/+3in most states "costing" or driving with the engine off is against the law as you can not react to an emergency where you might need to accelerate quickly to avoid some thing
Also driving 15 MPH under the speed limit is also against the law
- BLKMGK, on 06/25/2008, -0/+4Some new cars use an electric motor for their power steering pumps to gain MPG - mine does. Hybrids do too. If you think about it you'd understand why that is - same with their brakes. Guess what most of these guys are driving (and no I'm not).

- cardinalb, on 06/25/2008, -5/+20Also over inflating your tyres could have serious consequences when its time to stop in a hurry. Brakes are also often assisted by the engine as well as the power steering so these guys are incredibly stupid. Saying that we do need to do more to save the planet.

- BalooUrsidae, on 06/25/2008, -0/+3Which would you rather have:
1) Plan ahead a little more for a few minutes additional travel time and save money now available for toys or retirement...
2) Drive like a nutter with the air conditioner on to save a few minutes and send that money off to the oil barrons?
Which brings up another point:
Do you even like the people you're giving your oil money to? If not, why would you want to give them even MOAR money?

You should not be exceeding the speed-limit, there's just no good reason to do it.- whodat807, on 06/25/2008, -0/+260 is actually 10 miles under the speed limit in most places.

Hypermilers do 60 in the far right *slow* lane.
The person doing 60 in the fast lane is on his/her cell phone, not paying attention to the road. - paradexes, on 06/25/2008, -1/+2Those people often tend to be royal self righteous pricks.

- virtualonliner, on 06/25/2008, -5/+44Some of the tactics they employ are really useful. But some, if not everyone is hypermiling, are going to increase the consumtion of gas over all. FTA "Hypermilers practice such unorthodox techniques as coasting for blocks with their car's engine turned off, driving far below speed limits on the freeway..." Now if you are driving "far below" speed limit on freeways, you are going to cause traffic congestion. That would decrease gas mileage for cars stuck in there...Just a thought
- aladrin, on 06/25/2008, -4/+8Indeed. Their tactics only work because they are the only ones using them. If even half the people on the road used them, they would interfere with each other so much as to be pointless.
- BLKMGK, on 06/25/2008, -2/+5If we all drove slower on the highway congestion wouldn't increase any more than it is now. It would suck but that's beside the point. Wind resistance goes up exponentially as MPH increases. Driving slower DOES save gas but I prefer to just get behind a big truck if I'm that desperate - and you need not snuggle to save gas. Even 5 car lengths back the truck is helping...
- Konrad9, on 06/25/2008, -3/+4My 'far below the speed limit' is 60mph in the slow traffic lane, which is 5mph below the limit.
The people you are thinking of causing traffic congestion are idiots who aren't paying attention to traffic in the other lanes.
People on their phones, eating, reading, putting on makeup, smoking, etc.
Also, the only idiots who get 'stuck' behind me are idiots who run right up behind me and tailgate me for 10 miles. There is no need for that, they can easily switch lanes on their way up to me.
No, I'm not going to go faster, it doesn't matter how close they get to me, and the fact they think I'm going to go faster only shows how stupid they are.- Skwerl, on 06/25/2008, -1/+7In the state of California, if more than three people are held up due to your inability to maintain the speed limit, it's your duty to pull over and let them by.

If you can pass in another lane going the same way on the left, slow traffic isn't obligated to do anything different. California isn't a good example to give, as they're fairly ass backwards on a lot of things the rest of the country gets right.

- silveravnt, on 06/25/2008, -2/+3It also causes people to speed around them using more gas.
- BalooUrsidae, on 06/25/2008, -0/+4Actually, if everyone slowed down to ~45-50 all the time, traffic overall would flow more smoothly. Hard acceleration requires hard deceleration when you catch up to an obstacle, which is what causes the jam. Faster traffic causes larger traffic jams, not slower.

- Cargo8, on 06/25/2008, -8/+62Too bad this article could give people very unsafe ideas...
Turning the engine off can lock brakes and steering (at least the article gave warning here) and usually does in most modern cars. Not to mention if people abuse it and do it often, it is null because turning on an engine uses more gas than never turning it off (in some cases & timing-dependent)
Driving below the speed limit is dangerous and can cause traffic for others. Thanks a lot, you improved your gas mileage and killed everyone else's, douche... Not to mention normally ideal gas consumption speed is 55-65 mph (which is why the speed lmit was changed during the oil embargo back in teh day)
Tire pressure is very important to the performance and safety of a car. The wheels/tires are the only 4 contact points between the car and the road, why f*** with that? High tire pressure can cause significantly less grip between the tire and the road in addition to being more prone to blowouts, especially when "far beyond car and tire makers' recommendations"...
Good job guys...- kpmoore, on 06/25/2008, -2/+6I absolutely agree with you, but just wanted to clarify that the ideal gas consumption speed is the slowest speed that the highest gear will allow. Your average car can do ~45mph in 5th gear, so that is typically your ideal speed. EPA highway mileage tests are performed at 48mph I believe.
- LeRenard, on 06/25/2008, -1/+5That's a good rule of thumb.. but not literally true. Ideal gas consumption points differ from engine design to engine design and the designers and engineers spell that out in the Brake Specific Fuel Consumption (BSFC) map. Its a chart of fuel consumption against RPM and load. In normally aspirated engines, you almost always see the lowest consumption at the RPM of maximum torque output and less than 100% load. My 1NZ-FE powered Yaris has minimal consumption at about 2250 rpm and 70% load. On level ground traveling about 45, I get better mileage in fourth than fifth, even though the car will accelerate fine in 5th from about 35 up and not hit 100% load. My best economy is in whatever gear keeps me closest to 2250 RPM for my travel speed. Forced induction cars can have very unintuitive "sweet spots" in their maps due to the efficiency of the compression mechanisms. Oh, and the EPA recently changed its testing methodology to a higher speed, which is why MPG ratings on 08 vehicles have dropped.
- gamer31, on 06/25/2008, -0/+4My car can do 15 in 6th gear and still accelerate with no hesitation. I'd rather not drive that slow.
- mike17032, on 06/25/2008, -2/+1Vette or Viper?
- shifty2, on 06/25/2008, -2/+7I think the worst hypermiling idea is to catch the drafts of tractor trailers as they go down the highway.
There is an ***** here on the DC beltway who i have seen several times basically tailgating tractor trailers and trying to stay in their draft to dramatically decrease the air flow drag so he is off the throttle more.
I understand the concept, but looking at his crushed front bumper and hood makes me wonder if its even worth it.
not to mention that causing a huge pile up on 495 would increase everyone's gas mileage. He won't have to worry about it as the beltway commuters would draw and quarter his ass.
lastly, another terrible idea is speeding through corners in neutral so that you don't have to accelerate that much after a turn. sure you saved about a teaspoon of fuel, but you had to run over Billy and his mom as they crossed the street. - LeRenard, on 06/25/2008, -1/+3While they do some unsafe things, I wanted to point out that it is a fallacy that starting the car uses more fuel then letting it run. Maybe with a Kenworth, but not your average car. Starting your average sedan uses an amount of fuel equal to what it burns in about 10 seconds.. so letting it idle more than ten seconds is less efficient than turning it off. Cars haven't consumed a whole lot of fuel on start-up since the carburetor was abandoned. They consume a bit more than usual starting, but not like they used to. I've verified this with GPH instrumentation, btw. The information doesn't mean you need to turn it off while driving, but if you are sitting in a drive through, for instance, it might be worth it to turn it off depending on how long you are sitting there. I strongly suspect modern diesels see much of a benefit from idling over starting if any, however I haven't done any testing myself to speak to it.

- mcdougan, on 06/25/2008, -11/+11it is fun to try and beat your old records when it comes to gas mileage until some guy decides to follow you home because you were going ten miles lower than the speed limit in your vespa and threatens to beat you up... for being a "fairy" its all good though i saw your parking decal mr golden crown vic... and i know you use the non resident floor on the west deck at school you'll get yours one day

- BalooUrsidae, on 06/25/2008, -1/+2Sure you can. It's called "lift your foot off the gas." Do the math: You only save a few seconds to a couple minutes on a crosstown or cross-region trip. Most vehicles built since the 1970s get best fuel economy at around 46-48 MPH, you're just wasting money and making fuel that much more scarce going faster than 50 (60 if your vehicle is unusually aerodynamic).
- smellytim, on 06/26/2008, -0/+1are u serious about not going faster than 50? thats ***** ridiculous. why dont we try going slower than 75 first and then we'll see where it it goes. these guys might go that slow but no one else does.

- LenBaird, on 06/25/2008, -2/+2I just got a scooter that gets 100mpg while I zip around @40 mph on a fun little ride that handles great (Aprilia sr50). Yea, I can't drive on the highway with it, but It's a lot better than the techniques that the "hypermilers" use.
- FireandFlame, on 06/25/2008, -9/+4How does shutting the engine off and coasting for blocks help in mileage if it takes 1/4th of a gallon to get the engine restarted anyway?
- Bisqwit, on 06/25/2008, -3/+7Only older engines require that much fuel to restart.
And, if the car is running, starting up the engine does not require gas at all. In fact, when you relieve the gas pedal, the car is not consuming any gas, as long as the RPM is high enough (say, > 1200) that the driving computer doesn't think that the engine is in danger of stalling and forces fuel to be used.- BLKMGK, on 06/25/2008, -0/+4Wow, like the ONE person posting with a clue and you got dug down? what you said is 100% correct so long as the car is kept in gear when the pedal is let up on - anyone with an MPG computer can see this as the numbers show dashed when you let off the gas on the highway displaying instant MPG. Many of the hypermiler guys aren't keeping it in gear though apparently and yeah that's more dangerous although it does increase cost time since there's no compression losses. Posted it elsewhere but starting the engine doesn't require jack for fuel if it's EFI and warmed up. Just popping the clutch while coasting requires even less
- johnnyboy239, on 06/25/2008, -0/+4Mostly because that's not true, it takes seven seconds of gas running a car at idle to start a car, with any fuel injected engine.
Meaning that if you are going to be in one spot for more then 7 seconds it's more efficient to turn the car off.

for an average car, a 4cyl dohc, when you start your engine you spend roughly 5 miles of fuel, so this is pretty flawed.

- BLKMGK, on 06/25/2008, -0/+10*****. You've never tuned a car's EFI computer have you? It takes nothing to start a warmed up car, the enrichment value is minuscule and the afterstart RPMs are also tiny. FAIL!
- username484767, on 06/25/2008, -6/+1thank you for being a tool for my amusement :-)
- bippitybop1, on 06/25/2008, -1/+2The fancy instrument to monitor gas mileage, is nothing more than a vacuum gage, My 1999 BMW 328i has one built into the speed odometer panel. It can be used to train yourself to push lightly on the gas pedal.
- BLKMGK, on 06/25/2008, -0/+4Actually no, a vac gauge isn't that good an indicator. My car actually has a nice digital readout for MPG, THAT is what many people are building and installing into their cars. They monitor injector pulsewidth and speedometer pulses to calculate MPG. HackADay highlighted a gauge being built not long ago, some folks just plug into their OBDII data port for similiar readings.
- LeRenard, on 06/25/2008, -0/+6The weapon of choice of most hypermilers is the Scangauge II, which monitors a ton of engine parameters via the OBD-II computer port. It measures vehicle speed, fuel pressure, injector pulses, air density, 02, etc. etc. and computes the fuel consumption from there. Much more accurate than vacuum but with the same intent. The advantage of the scangauge is that it records averages, peaks, minimums, etc, for entire trips or periods of time, and it also relays otherwise hidden data from the computer for display, like coolant temp, intake air temperature, manifold pressure, voltage, engine load, etc.
- yacks, on 06/25/2008, -3/+17oh screw mileage.. :) I like to floor it off the red just to get to the next red where I floor it again. :) I don't like other people getting ahead of me because of idiots that change lanes in front of you for no reason other than to just go slower than you are.
- Ravatar, on 06/25/2008, -0/+17Best part is, occasionally you beat the next red and all those SUCKERS are stuck there for another 3-4 minutes.

- sabach, on 06/25/2008, -7/+5It would help a lot if people would just do the speed limit and not routinely go 10 mph over. And slowly accelerate between lights rather than haul-ass and then have to brake very hard. It just seems like common sense to me.
- aladrin, on 06/25/2008, -2/+4Getting up to speed quickly is better. If you're going to accelerate, do it quickly. Breaking very hard is defintiely bad, though... It means you were going too fast in the first place.

- Mistlefoot, on 06/25/2008, -4/+19The 1st guy in the article advises he saves fuel by driving 10mph slower then the speed limit - which takes him an additional 16 minutes per commutes. He also says he gets 100mpg. He is corporate jet pilot.
Math says his commute is around 62 miles in each direction - so 124 miles per day. At 100 miles per gallon he saves 1 1/4 gallons - or $5.00 worth of gas a day. Good to know a corporate pilot's time is only worth $10 per hour.
I also wonder how much more fuel he wastes by blocking all the traffic behind him while driving 45mph on the freeway.- BLKMGK, on 06/25/2008, -0/+2He said he takes back roads, that's likely part of the reason for the longer time taken too.
- Konrad9, on 06/25/2008, -1/+2If he's blocking traffic on the freeway, I laugh at the people he blocks.
Any ***** too stupid not to switch lanes when they see someone going 45 deserves to get 'blocked'. - Kevin108, on 06/25/2008, -0/+1I would say he blocks none. That is what the left lane is for.

- CrazyZ, on 06/25/2008, -2/+3If you commute a lot, just by a motorcycle. Even though you may not ride it in the colder months, you still more than make up for it with how much you'll save. A decent bike have less maintenance costs, get between 40 - 60 mpg on the highway and it's a hell of a lot more fun than a car.
- aladrin, on 06/25/2008, -3/+1The solution to saving money is not 'Buy more vehicles'. That's idiotic.
- CrazyZ, on 06/26/2008, -0/+1Obiously, but there are many people out there in the market for a new vehicle of some sort and if gas is a consideration, then a motorcyle is the way to go in many instances.

- CrazyZ, on 06/25/2008, -0/+3A decent used bike will set you back about 5grand. At 50 miles a gallon it's a much better "cost savings" than a prius.... The solution to saving money is buying a different vehicle that has a small up front cost and unless you buy a super sport, your insurance is going to be less than you think.
- mike17032, on 06/25/2008, -2/+3Yes but the bills that will pile up after a bus hits you and you end up in a Coma might off set those savings.

- evilrevolution, on 06/25/2008, -6/+11. Use Lighter Grade Engine Oil
-use the oil that's best for your engine.
6. Skip the Premium Octane
-costs more but you get better mpg, so it works out the same. better 4 ur car as well.
8. Get it in High Gear
-Your car is at peak economy when your at the sweet spot right in the middle, at the point where its easiest to accelerate.- BLKMGK, on 06/25/2008, -0/+7Ummm NO. Thinner quality oil, particularly synthetic will increase mileage without increasing wear. Engines can pick up as much as 16HP at the wheels just by switching to a good synthetic.
Premium octane - higher octane gas explodes LESS easily. It's used in higher compression engines to stave off detonation. Use the PROPER octane for yuor engine. Higher octane on a low compression engine will LOWER MPG and power. Low octane gas on an engine who's compression requires higher octane gas will force the engine to retard timing and LOWER it's MPG and power. It can also cause engine damage over time since detonation must occur in most cars for the timing change to be sensed.
Peak economy will occur at peak torque. Peak torque is where BSFC is highest. Put it in high gear and get the tach to peak torque, not HP, and you'll do the best. you can often find engine power graphs for various vehicles in car reviews or hell just have it tested. Seat of the pants is CRAP for figuring this out. - bemenaker, on 06/25/2008, -1/+1Premium gas will rarely be worth the extra money to you, but it's not too uncommon that the 89 octane will pay for itself. My '97 Accord gets enough extra gas mileage on 89 to more than offset the extra $.10/gallon, but 92 octane is a complete waste for me. You need more compression to make use of the 92 octane.

- BalooUrsidae, on 06/25/2008, -0/+1To suggest that utilizing water is the same as wasting oil to carry a 5 seat vehicle with one person in it really demonstrates how little clue you have: If worse comes to worse, you can re-use water after you've peed it out or bathed in it just by filtering and distilling it again. Try that with used gasoline.
- mike17032, on 06/25/2008, -4/+6Well thats just about as unsafe as you can get.
Over inflated tires? Sure they give you VERY SLIGHTLY better MPG, but they also vastly reduce the grip on the road. Hope you dont have to stop fast for anything.

It won't be long before one of these guys kills someone cause they were busy starting their car or hitting their soft/unresponsive brakes because the engine was off.
- bemenaker, on 06/25/2008, -4/+2Why are these loons getting so much press, and especially when they aren't being chastised for unsafe and stupid practices? Driving down the road with you car turned off, (ILLEGAL), let's see, no power assist on the brakes, when they are designed to need that vacuum assist. Driving way below the speed limit on the highway, this is dangerous, ILLEGAL, and backs up traffic causing everyone else to burn MORE gas. Tailgating, Illegal and dangerous. Extremely slow accelerations, well that's the leading cause of the traffic backups on interstates right there, well, coupled with over braking.
This is retarded, and getting too much glamor press. Let's be honest about this selfish dangerous practice.- BassJunkie, on 06/25/2008, -2/+2I seriously doubt driving UNDER the speed limit is illegal on highways, as for it causing more traffic to backup that is complete crap. If the car in front of you is going to slow OVERTAKE! Most highways I've seen on tv shows of the US show they have at least 3 or 4 lanes so the only way you'd be held up is if all the lanes are blocked, in which case everyone is driving below the limit!
If you also read the article the guy they speak to says he won't follow any closer then 3 seconds behind a truck, which is perfectly adequate considering I learnt the 2 second rule!
I have found that once I stopped rushing everywhere I saw a good improvement in my mileage, after all there's no point rushing into a traffic jam as you then just waste petrol getting back upto speed! It's much better coast to stopped traffic, a technique that is easier to understand once you start cycling as you notice how much more energy it takes to get started from a standstill versus a rolling start :-)- bemenaker, on 06/25/2008, -1/+1You had better go check the laws again. Yes it is ABSOLUTELY illegal to go more than 10 mph under the speed limit on the Interstate unless there is a hazardous condition, ie: snow, heavy rain, truck load of pigs running wild in the street.
It's the people who don't speed up after jamming on their brakes that cause traffic backups.
How often do people on the lane next to a slow moving vehicle slow down because of the lane next to them going slow. It happens every single day on the interstate when I'm driving home.
When you tailgate, you have to be right on top of something to draft, being 3 secs behind a truck, and you get no benefit of drafting, and BTW, when you draft, you just offset your saved gas to that truck in front of you. Now he has to pay for you. In essence, you are stealing gas from him.
Learning how to maintain the flow of traffic would do far more overall than this stupid crap would.- BalooUrsidae, on 06/25/2008, -0/+1. Yes it is ABSOLUTELY illegal to go more than 10 mph under the speed limit on the Interstate unless there is a hazardous condition, ie: snow, heavy rain, truck load of pigs running wild in the street.
Check yourself before you wreck yourself. No such law exists. In fact, bicycles are permitted on the vast majority of interstate highway mileage in the US (the practice only being prohibited in 22 east-coast states where the population density is so high they don't have room to put in proper shoulders). Most bicyclists aren't going to be going faster than 30 unless they're going downhill, and the police leave them alone.

Driving below the speed limit is not illegal. Driving faster than it is. And to suggest that going slower wastes more fuel strongly implies you don't get the concept of road and wind drag in the slightest.- SofaKid, on 06/25/2008, -0/+0Best speed for fuel efficiency is 110 km/h.
- BassJunkie, on 06/27/2008, -0/+1I understand enough about friction and drag to understand that there is a noticeable "sweet spot" when travelling at highway speeds. Once exceed a certain speed to amount of energy you need to put in to increase speeds starts to increase much quicker then your speed as the wind resistance is greater, hence these people use the slipstream of a truck to reduce their drag!

Also, drive a manual, people. Not really hard to coast with the engine off in a manual. - icexe, on 06/25/2008, -3/+3This type of obsession is not uncommon. in fact, lots of people become so focused on achieving a goal that they completely lose sight of what the originally intended to do. Take for example the guy who's obsessed with overclocking his CPU. Eventually overclocking becomes the end in itself, he'll do nothing but tweaking, adjusting, and running endless benchmarks on his PC instead of actually using his PC.

Also not surprising given that regenerative braking accounts for much of hybrid fuel savings, which is why hybrids get insanely good city mileage, but fairly lousy highway mileage compared to their city miles. My friends who have Prius's tend to get 60-70 in the city, half that on the highway.
