- wrenchone, on 05/06/2008, -4/+28These tips are all well and good, but most take it to such an extreme that they become silly and or dangerous. Clean out your trunk and properly inflate you tires? Sound advice. Plan your drive to take in account a possible headwind? That's impossible and really stupid. Depending on your car, shifting into neutral in an auto will waste more gas than coasting in drive. Shifting into neutral instantly puts the engine in idle since its no longer connected to the wheels and will stall otherwise. Costing in drive keeps the engine turning, and the computer will only engage idle once the rpms dip below idle speeds. Any advice that tells you to turn off your engine while driving is dangerous and should not be taken. No engine means no power steering, enough brake power for ONE stop, and no means to accelerate if needed. Saving 10 cents on your next fill up is not risking your or more importantly MY life.
Use common sense, drive smoothly, and don't have a lead foot you you'll save plenty of gas. - inactive, on 05/06/2008, -0/+23Step 1: Live in Nebraska.
Step 2: kill self because you're stuck living in Nebraska. - cl2yp71c, on 05/06/2008, -1/+19I honestly thought that 1) was a multiple choice question.
=/ - Ajajadude, on 05/06/2008, -0/+17I think the city I live in needs to be taught that designing the traffic light system to DISRUPT the flow of traffic (the words city officials have used) kills fuel economy. My mileage has dropped by about 3 MPG around town since the morons decided it would be a good idea to setup the timing so you stop at every ***** light.
God, it pisses me off. - thashiz, on 05/06/2008, -1/+15Just a note, according to the Mythbusters' tests, air conditioning is only more fuel efficient when the car is moving at 50mph or faster.
- mikhial66, on 05/06/2008, -0/+13All you're doing is slowing down traffic for every one behind you. Having two cars go the same speed next to each other is the most aggravating thing on the road.
- yaroze, on 05/06/2008, -0/+11Ride a Motorcycle.
- idavidtang, on 05/06/2008, -1/+12107) Make speed holes.
- swordedge, on 05/06/2008, -0/+10drive it with the tail gate up, mythbusters busted that one.
- yessuz, on 05/06/2008, -0/+10TIP NO. 105:
To have a car with a small engine is OK. Here, in Europe, 1.4 liter car is quite normal (ant 2.0 is more than enough). You can go at all MAXIMUM speeds without any problems and to save fuel.
TIP 106: Diesel engines uses almost 40% less fuel than petrol.
If americans could THINK about that.... - inactive, on 05/06/2008, -0/+10What I did get is that your post exhibited the stupidity of the average Digg user. What I didn't get is that you aren't one of those users :)
- Kerath, on 05/06/2008, -2/+12105) Mount a spoiler on your trunk. Upside-down.
106) Put a windmill on your roof and wire it to the battery. - thanakar, on 05/06/2008, -0/+9102) Use a block heater
Pre-warm your engine with an electric block heater. Engines are most efficient at full operating temperature, and the block heater helps it get there sooner. About 2 hours is the maximum time needed to pre-warm a small engine.
Waste electricty to conserve a bit a fuel? How much fuel are you actually conserving by preheating your engine? - feliks2, on 05/06/2008, -0/+9Hmmmm, I think they need to buy a HYBRID 5-liter monster, so that they only consume the equivalent of a 4 litre monster.
- maddvibe, on 05/06/2008, -2/+11These are great tips. The more it costs to pay for fuel the more these become relevant and the more people will start paying attention. Best one is probably windows up, I can't tell you how many people I know that roll their windows down thinking they are saving fuel. It can be a challenge convincing them they are really wasting more fuel because of that.
- Genthree, on 05/06/2008, -1/+10err, I think for most people it's about saving money rather than saving the planet. Gas is ***** expensive.
- cliffdavis, on 05/06/2008, -0/+9Because the average American driver is as confused by a yield sign as they are by a page written in Arabic.
Each morning I go through three intersections with yield signs, and without fail each morning, someone in the line of traffic will come to a complete stop at one for no good reason (usually the one at the top of a hill, no less). These are the same people who drive down a highway on ramp, only to stop, and attempt to enter traffic going ten mph. - Kerath, on 05/06/2008, -1/+10You didn't get it.
- OhTheHumanity1, on 05/06/2008, -1/+9I get to these lists and I think, "Oh, well this will be handy" and then I read 10 of them, realize I have to do that 10 more times, and suddenly I'm thinking, yeah, I really don't care that much
- tbk123, on 05/06/2008, -1/+9I never even thought about luggage racks!
- swordedge, on 05/06/2008, -3/+10Hypermilers, those are the nuts that take the off ramp at top speed then drive slowly in the right lane.
- inactive, on 05/06/2008, -1/+8Wow, the one I never thought about was driving with your lights on. I have an older truck, so I wouldn't be surprised if that makes a difference. It's interesting that "automakers have an exemption from CAFE testing which permits vehicles' fuel economy to be tested with the lights switched off."
- habhi, on 05/06/2008, -0/+6I hope girls don't take tip number 4 to heart.
- guitarmaster, on 05/06/2008, -0/+6Are these tips a little extreme? Why not just
105) masturbate out the window
to reduce load - feliks2, on 05/06/2008, -1/+7You sound like a complete *****, but really, I agree.
- AngelBunny, on 05/06/2008, -0/+520) Take advantage of the wind
If possible, time trips to take advantage of strong tailwinds. Avoid setting out into strong headwinds/crosswinds.
How would one go about doing this? - feliks2, on 05/06/2008, -1/+6I just read through the whole damn thing, and every bit of it was more painful than the last. These people are lunatics. Basically everything they offer would save a completely negligible amount of fuel, except for those rediculous "tactics" that excacerbate the traffic problem and prevent normal people from driving like normal people. I mean, looking for roads shielded from the wind? These people aren't in fifth grade anymore, surely they must realize that just because something "theoretically" works doesn't make it in the least bit practical. And they basically missed two crucial factors: an efficient car (not a hybrid) and a manual transimission.
- BurgerDST, on 05/06/2008, -0/+5This will not work. Opening the window and having your penis hanging out the window will increase drag {some more than others}. It can also be a hazard to unsuspecting pedestrians. Always be sure to take care of the load reducing before the engine starts.
- louiebaur, on 05/06/2008, -0/+5Work at home is the way I am going with it
- feliks2, on 05/06/2008, -0/+5Seriosly, there seems to be nothing worse than driving behind several slow cars all driving right next to each other when I very clearly want to pass them. The left lane isn't for driving next to trucks, its for going fast and passing people.
- dawglse, on 05/06/2008, -0/+5no ***** sherlock
- subliminalurge, on 05/06/2008, -0/+4I wonder how much gas you'd waste cruising around looking for all of the perfectly shielded roads to use in various wind conditions?
- mwomorris, on 05/06/2008, -0/+4Such as?
- subliminalurge, on 05/06/2008, -0/+4To actually be happy about the increasing gas prices is both short-sighted and, frankly, stupid.
Fuel prices don't just affect people's driving habits, they affect EVERYTHING. All of those higher prices at the grocery store? A result of increased fuel prices. Instead of worrying about the "poor, poor planet", how about worrying about the poor single mother who now goes hungry 4 nights a week so that she can afford to feed her baby? Or how about the single mother that my company was just forced to lay off since the impact of rising fuel prices means we can no longer justify her salary.
The fact of the matter is that extreme rises in fuel prices will destroy lives, businesses, and, if prices go high enough, the entire global economy.
You have to be one sick ***** to actually be celebrating that. - snoopduggydugg, on 05/06/2008, -1/+5These things are always helpful... it's still tough though, considering I drive a pickup..
- Nepenthes, on 05/06/2008, -1/+5Please, if we all act now, we can avoid the acceptance of the term 'hypermiling'... Remember your children will inherit this language - do it for their sake.
- Pixelpaws, on 05/06/2008, -0/+4Tailgating a semi is just asking to get into an accident. The driver can't see you and you can't see anything around or in front of the rig. Saving fuel isn't worth risking your life.
- nevetando, on 05/06/2008, -1/+5Sweet Jesus on a pogo stick...
Listen, Every body on this planet knows to inflat your tires, to drive consistanly to not burn out on traffic lights, etc, etc.
When these sites start advocating potentially dangerous techniques such as drafting and coasting through turns and timing lights as to not have to brake, well you are now becoming an unsafe driver. not only is your attention taken away from your surroundings, but just setting yourself up for traffic citations.
I guarentee you that hypermiling god wayne what ever his name is runs every single stop sign he can... just think about how much gas you can buy with that 300 dollar ticket... - ClunkClunk, on 05/06/2008, -0/+4Almost all of these have at least some sound sense in them for fuel economy (though not all of them are sound in a legal or safety sense, but I digress). However this one is just stupid:
61) Parking tactics: orbit to bleed momentum
If you find you have too much momentum after reaching your preferred parking spot, continue coasting further down the row or "orbiting" a spot until you can roll to a stop in position without touching the brakes.
(The extent to which you might continue 'orbiting' depends on whether your engine is on/off and whether you're driving a manual or automatic. Also, it depends on traffic in the lot, obviously.)
Since you're already at speed, you've already burned the gasoline to get to that speed. By orbiting, all you're doing it wasting more fuel by the engine running at minimal rpm. The concept of using brakes = using fuel is only true if you have to re-accelerate back up to speed, which granted, is a huge amount of the time. If you're parking and shutting your vehicle off, 'orbiting' doesn't do anything except waste 30 seconds worth of fuel. - jbmcb, on 05/06/2008, -0/+4My procedure for cooling down my car:
1 - Drive with the windows down, the vent open and fan on high for a few minutes to cool off the interior quickly.
2 - Close windows, turn on A/C for about five minutes
3 - Switch to A/C recirculation for a few minutes
4 - Turn off the A/C compressor, leaving it on recirulcation
The vents will continue to kick out cold air even after the A/C compressor is turned off, as long as recirculation is still engaged. It wears off after a couple hours, but it's much more efficient than running the compressor the entire time. - AnotherGopher, on 05/06/2008, -0/+3In summary: Drive downhill on a warm night when there is a tail wind with the lights off, in the same lane as everyone else.
- legoalert33, on 05/06/2008, -0/+3If you don't believe the real life testing on Mythbusters here is a more documented study published by SAE.
http://ecow.engr.wisc.edu/cgi-bin/getbig/me/363/gh ... - CataKlysmiC, on 05/06/2008, -1/+4BRING A TOWEL!!!
- darkciti2, on 05/06/2008, -0/+3Most frequently, it's running stop signs. Starting a car from a complete stop takes a lot of energy so keeping the vehicle momentum going is very valuable mileage-wise.
As a hypermiler, the only other one I can think of is running yellow lights (very infrequently, but pushing it). I try to time my lights, but sometimes I don't make it through an intersection before it's yellow. - yessuz, on 05/06/2008, -0/+3try to use smaller engine
- idavidtang, on 05/06/2008, -1/+4Proof.
http://mythbustersresults.com/episode80 - mikhial66, on 05/06/2008, -2/+5Fill up when its coldest. The hotter gasoline is, the more it expands, and the more it costs you for the same fuel.
- mwomorris, on 05/06/2008, -2/+5True with windows, but I would say the best one is not driving.
- BioHMMWV, on 05/06/2008, -0/+3All of the suggestions looked good, except for 71 &72. Cruising in a lower RPM will not increase efficiency. Driving within the peak RPMs will increase fuel economy. It can make the difference of 2-4 extra miles per gallon. For instance, my Cummins diesel at 70 MPH gets 19-21 MPG at 1,650 RPM, and gets 22-24 MPG at 1,800 to 2,000 RPM.
- darkciti2, on 05/06/2008, -3/+6Coasting in drive reduces the distance your vehicle will travel on an equivalent amount of burned fuel.
Here's an experiment:
Put your car in neutral as you coast down a large hill, you'll coast much farther than if you leave the gearing system engaged in D rive. Why do you think manuals have ALWAYS gotten better gas mileage than Automatics for the past 40 years?
Your engine won't "stall" and even if it did, by putting the car back in gear it will simply "push-start" the engine. -
