  • Why is there always some kind of fucking argument under every fucking video??

  • @sledgedrummer everything in life is an argument

  • Idling is hard on my engine?

    So you're telling me that by my car sitting in my driveway running at 900 rpms it is harder on my engine than the constant acceleration and braking between 2 and 6k rpms?

    How about this...when it comes to cars, let the men give the advice. Eh?

  • Metric system? I smell canadian. Canadians use cars? Don't they use dogsleds?

  • @rcollins211 youre a fucking dumbass

    go back to living in your texas farm shed you moron

  • @XxdemonzhackerxX Lol and you assuming I live in a Texas farm shed is any less of a poor cultural stereotype than my joke how? I'm sorry if you're canadian, but you don't have to be mad about it, I'm sure there are support groups out there if you need help.

  • who cares just floor the fucker :)

  • how's idling bad?

  • @imthechandyman i know yeah ,thats the best hting for the bloody engine

  • why a girl ??? ur lame

  • i dont wanna slow down! i wanna go fast!

  • This video was horrible. Biggest waste of 2 minutes. Having the a/c on at highway speeds is actually more fuel efficient. But if your this anal about it, simply roll the windows up and cook with no a/c. Best mpg.

    Needs a different title. More like let me state the obvious for you.

  • did she say that gas prices drop more often than they go up, or am i hearing things?

  • You know whats worse than your car sitting and idling? Constantly stopping it and starting it at every light

  • easiest way to save gas is to reduce weight. if it don't need to be in the car take it out. i completely removed all of my cars interior panels and seats. mpg went up from 34 to 62. with a 2000 eclipse. what im trying to say is CLEAN UP YOUR CAR. trash cans are at gas stations for a reason

  • Sorry, I think this channel should be the fail blog rather than HowStuffWorks....but AC running or not has no effect on the MPG you get. Because with the windows down, it causes more drag and less MPG versus AC on and windows up.

    ill avoid idling like you said, but any speeding tickets from blowing stop signs and red lights are going to be paid by you.

  • Small TITS!!!!!!!!!!!!!!!!!!

  • stupid canadians, go get a bear fat and stick it into the fuel tank

  • how the fuck can electric air conditioning affect your fuel econnemy,

    the alternator/generator is always connected to your fanbelt so you are always generating excess electricity,

    even when your using that electricity it wont increase friction in the alternator/generator. This applies to all electrical components in your vehicle,

  • @mooreonic because your air conditioning needs a compressor to compress the freon back into a liquid.

    this compresser runs off a belt that is conected to your engine. when AC is on it creates more friction. IE less mpg. =)

  • @kddcc if the compresser is also connected to the engine by a belt then it will always be going as well......

  • @mooreonic the compressor is allways spining yes. but when you use the compressor or "turn it on" it draws more energy to run. In turn friction on motor.

    I know this because when i turn the ac on in my jeep (4cly) you can actualy feal the engine lag down on the RPMs just a bit. not much though.

    I may be wrong because its a 1995 and the new vehicles may run off the alternator. But even then when you draw alot from the alternator (light,ect..) it lags the motor for my jeep.

  • You are from USA?

  • @the krutor, fuck off im not!

    @kddcc i get the compressor doing it but not the electric part, you cant increase the friction of a electric alternator/generator by using more energy though, it just doesnt act like a compresser,

  • if the ac isnt on meaning its not compressing anything but when its on,it needs more energy to compress

  • anyone in vancouver go out to aldergrove then its cheaper XD

  • Show us your titties and i will watch XD

  • looks like they are small dude! :D

  • nothing wrong with the small titty!

  • she doesn't know what she's talking about.

  • "idling is hard on an engine. "

    wat?

  • only if your car has a carburetor.

  • @USGiorgi i dont see how that makes a difference

  • @Paiste402

    well idiling an engine which uses carburetors instead of fuel injection, is bad for an engine. The carburetors supply the engine with too much fuel when they are idling.

  • @USGiorgi

    running lean sure now thats damaging but i didnt think a little rich only at idle did anything

  • simple answear BUY A DIESEL

  • she told us how to increse fuel efficency not how it works

    so basicly this vid is great if u wanted to increse fuel efficnecy but if yyour like me who wanted to know how it works she failed

    or plz correct me

  • i hope you don't expect you'll get the desired answer on "howstuffworks"

  • beans for gas. milk for gas. cheese for gas. anything that gives you free gas is a friend.

  • that didn't explain how fuel efficiency works at all

  • 1:26 "gas prices drop more often than they go up" OH RLY?!?!?

    Well, bitch then why does the price always stay above $2 a gallon?

    I guess that statement could be true, if the price was decreased is less than price increased each time... but still, wtf?!?

    oh and thanks for plugging your company

  • eheheh you are luky girak, in my conuntry 1 LITER is sold for 1,30 Euro...

    means

    1,9423 dollar for 0,26 gallon ehehh XD

  • 19 thousand dollars

  • i just came, seriously i couldn't resist

  • My car is 20 years old, has 125 hp, never made any maintainace, has only a half exhaust left (loud as hell :-D ), tires are sucking slicks and has over 150' miles. Still needs 3 gal/100 miles.

  • I would like to bone her.

  • gas prices go down more than up?

    thats a new one

  • dumb bitch doesnt know anything almost everythings wrong

  • got that right

  • your the dumb fuck your wrong

  • this guys getting his pantys in a bunch over a comment. I don't care about your pussy bmw, 4 cylinders use half the gas as 8, thats the point im getting at. I dont want to know how many mpg you get with your fancy chick car.

  • Thanks for saying absolutely nothing useful and that it's completely obvious. And a turbocharger doesn't always mean better MPG even driving like a grandma.

  • you have obviously have never driven a turbo charged engine.

    in my 1993 Nissan 300ZX Twin Turbo 3.0 Litre engine...

    If I am driving normal speeds and light acceleration, I get about 40+ MPG.

    BUT... If I open the throttle alot, push it harder, and go higher speeds, I seriously gett about 16 MPG at the lowest. This is pushing it hard.

    You really just have to drive a turbo engine. its a totally different experience from any normal car. Its just the best.

  • [to Foxy300zx] ya turbo cars are the way to go...my 2001 Volvo s40 1.9Turbo if I'm driving carefully I get between 38-42mpg...but opened up is around 18-20mpg....my day to day driving averages 33ish....with light mods.

    And you got to love the VW Turbo Diesel they have getting 55mpg....

  • glad to hear that someone out there knows what it is to drive a turbo engine car

    its the best

  • get a smaller engine and a turbocharger.

    also how the hell is public transport relevant? public transportation is dirty as shit

  • if you listen to the video you would learn dumb ass. she's talking about how you can save fuel. so go back to school heres your lesson next will be the pop quiz.

  • Yup Turbocharge small Diesel motor then add a propane assist tank kit.....easily get into 100mpg in smaller cars....

    Diesel Motors can be ran with so many alternative fuels and mixes.....

  • 2:18

    This lady is fucking clueless. She is such a tool.

    It is common known that all gas companies get together and make up the price of gas based on absolutely nothing.

    If gas companies were actually honest...the prices from one station to the other would jump dramatically and not just like 3 or 4 cents.

    then our fucking voted leaders are paid to act like nothing is wrong.

  • Here is one more: Get a 4 cyl engine and run at top gear. The lover RPM means that you don't use as mutch fuel than in a lower gear at higher RPM. It's common sense

  • can you cook??????????????

  • The Coquihala hwy speed limit is 120km/h

    and these tips are common sense and bullshit. To save gas, buy a 4 cylinder engine. FUCK

  • or buy a bike. they have the best gas mileage of all...

    until some idiot in a hummer runs your little head over.

  • rofl buying a bike might be a good idea!

  • not true bmw 530i v8 3 liter motors get 37 mpg. toyotas 4 cylinders 2.2 only get 34 mpg. so who is the dumb fuck ? you are. it's the liters that matters there is alot of stupid mother fucks here i sware. the more horse power you have, the less fuel that is used. " unless you punch it" thats why there are turbos too to helf fuel econ. to move your heavy ass piece of shit around think before you speak retard. and everything i just told you, look it up and finally you will be educated.

  • I saw a van with tires that had no more than 50% air in them. It was comical.

  • She actually said: try using public transport.

    For better MPG.

    God.

    GOD!!!!

  • fuck you

  • FUCK THAT!!! if its hot as hell im turning the damn ac on. 4cyl's sip enough gas as is.

  • Considering gas prices are only a SMALL FRACTION OF THE COST OF ACTUALLY RUNNING A VIDEO. Why the fuck would anyone bother with shit like this to save a couple pennies?

  • This video was designed for morons.

  • if i have a car i will let it idleing when i go to sleep like my pc

    and YOU lady u cant forbade me to do it.

    Women cant park, know nothing about cars, technology, and suck in politics go home please

  • Women don't know about cars. In modern cars, leaving the windows open and air conditioning don't actually reduce your gas mileage. Fuel injection computer controls keep your car at the same economy.

  • She said the speeds in metric units???

    She forgot to mention that accelerating smoothly and using cruise control also has an impact on how much you consume.

  • I heard that to it was helpfull us australians but she dosent know what she is on about I agree with using cruise control untill some prick decides to get in front of you and slow down

  • hahaha i can see her reading what shes being told

  • 120km/h? are you legally allowed to drive at 74mph in canada? O_O

  • yes...in avenue :) 80 mph

  • Not really, the posted limit is 100 kmh, but it's an unwritten rule that OPP generally leaves you alone up to 120 kmh.

  • Here in Portugal you can go at a maximum of 120 kmh on the highway

  • here in holland to

  • In North Dakota in the USA, 75mph. Minnesota 70mph. Iowa 55 to 65. It depends on the area of course. Headlights are a must, always! day/night. the toughest cops are in Wisconsin..when you drive through Wisconsin: slow the metal down !! here in California, whatever you do, don't mess with a pedestrian ! Ciao :)

  • Ways to save fuel

    Use a bike for town journeys

    High pressure tyres

    Coast to lights

    Don't overwork the engine on hills

    If in a long traffic jam on a slight down slope, turn off the engine

    Slow down/have a streamlined car to reduce wind resistance

    I'm sure there's others

  • how about we unite as a country and stop using gas to power our vehicles

  • fuck you electric motors will never win against a gas engine and plus we would have to recharge our lawn mowers every half hour and that can take up to 15 hours!!!

  • CommieKid didn't mention electric motors at all. The correct answer is: "We need to unite as a country. The US really hasn't done that since World War II, so I suppose the only way that will happen would be for WW3 to begin."

  • lol sk389

  • actually theres a car out there that runs purely on electricity and can go 0-60 in under 3 seconds. But its way to damn expensive.

  • wtf? she has an american accent but measures things in Liters and kilometers. ?!?!

  • Yes, some people, smart ones, realize that measuring units such as liters, meters and centimeters are most common and very popular all over the world. Feet, yards and miles and pounds...give me a break...what you just want to be different

  • yeah i absolutely hate our system. I can never get the conversions together.

    The problem was that when the US was founded, we used the British system because that's what we were used to. But then Britain changed their system to SI. So now we're using the British system which sucks ass. And now we can't change it because changing every label and especially road signs would costs billions and billions of dollars.

  • (measurement system) it may cost billions of dollars but there's also all the text books, and peoples minds that you can't change... sucks :/

  • liters and kilometers are part of metric system. Only america uses gallons and mile for units.

  • yes i know! i live in the friggin country! and no, it's not to be different! i said that the british used it and since america was a british colony, we used the british system of pounds and miles. but then britain used the metric system. by this point it's too expensive to change

  • She's Canadian, as the PetroCanada tanker might suggest.  She could probably have done the entire presentation in French too.

  • In UK petrol is measured in litres, but speeds in miles per hour - we have a real mix. Also a UK Gallon is 4.54 litres and a US gallon is only 3.78, so I guess our cars get more miles per gallon lol

  • " Gas prices go down more than it goes up." Can anyone else tell me what's wrong with what she said? She was making all sorts of good points but when she said that I about fell over. lol

  • lol yeah times change i guess haha

  • When prices rise, they jump.

  • How fuel efficiency works:

    "use public transit", lol

  • LOL. Little confusing. I know..haha

  • yeah, this video is about fuel efficiency in a vehicle not saving the planet hahaha

    she could have said

    "maintain your engine, dont drive like a badass, keep rpms as low as possible

  • or you can do give up your car, and buy a mule, she should told that, instead to be advising us things that we already know,

  • jesus fuck. this chick is like a fucking robot.

  • lol, yeah..

  • Junk the SUVs and buy a VW or Toyota.

  • Diesel BMW's are the most efficient cars in the world.

  • what about mercedes? eh? what about other diesel engines/cars?

  • Is this tried and tested?

  • but do you know when you open the windows it causes a drag and that uses more fuel aswell

  • thinner oil will also get better gas millage but you have a risk of hurting the engine

  • no! using the manufacturers recommended oil is best!!

  • stating the obvious!!!

  • yah ey

  • "avoid ideling, it can be really bad for your engine"

    haha, yeah cos 1000rpm might overheat the engine :|

    stupid bitch.

  • Actually, an idling engine is under a fair bit of stress because it's working hard to overcome the force of the valve springs and friction, it's running slower than the speed at which it's designed to run, at the absolute minimum to stop it stalling - which is why idling takes extra fuel. Oil pressure is low at idle, as most oil pumps are driven by the crankshaft and as such, low speeds mean low oil distribution.

    Engines are more comfortable at 3000RPM than at 1000RPM.

  • sure......

  • 2 cent off WOW!!!! thats a lot

  • If you go by Litres it is lol

  • hahaha

  • gas gas gas get a hybird people it's way better im bying a smart car less gas wooooooooooooooooooooohooooooo­oooooooooooooooooo yes man

  • Or convert your current car to electric.

  • electricity cost more to make than petrol.

    you have to burn more coal to make electricity. maybe a tiny fraction of electricity comes from water and air. but coal is where electricity comes from and will always cost more to make than using gasoline.

    we just need more turbo charged engines comming out thats all. they are the best on fuel... well, when you arent boosting it :) thats the fun part about turbos

  • I live in an area completely fueled by hydro electricity or nuclear power.

    Converting to completely electric would be the smartest thing for me, and 3 million other people who live in the same area, to do.

  • you have to admit...this scank looks like a tool :)

  • Oh gods yes.

  • dude that's not going to do anything then you have to charge your car for 10 hours before you can drive it agen

  • Most have a quick charge which will get a good charge into it in under 3.

  • what does a woman know about cars...

  • stop building OUTLAND SUBURBIA, stop cities from building LEGO STYLE APARTMENTIAS AND ALSO STOP buying the cheap chet autos and ask your Cities and Government by lowering the speed limit to 55mph, and you want cheap gas price. GO TO MEXICO , the government subsidizes for its citizens

  • a usted se le hace barato la gasolina en mexico, pero a los ciudadanos mexicanos se les hace cara la gasolina, porque en USA los sueldos son mas altos y en mexico los sueldos son mas bajos.

  • gas dropping more than it goes up?????????? i wish man, i dont think ive seen it go down even 1 cent in about a year

  • She means in frequency - not in amount! They typically go UP once a week, and down every other day. It just goes UP by 10-18 c/L but only down 1-4 c/L every other day.

  • NO your out of your mind

  • Cal disel is almost $6.00 per gal. It will get there for sure. So will gas.

    If you think your in trouble now. Check out this man on You Tube. David Walker... his accounting firm handles the Gov. spend min and look this up. Educate yorselves America... we have sit on our asses for 30 yrs and the politicians have taken us to the cleaners. Going to hell in a handbasket. David Walker... check his name out , Newport Beach, Ca.

  • yeah really she doesn't know crap

  • Remember, these videos were made for elementary and middle school children--not adults.

  • I'm between middle school and adult.

  • Best way to save fuel: Don't use it.

  • Contrary to popular belief running your air conditioner does not affect your gas mileage. The AC runs off the serpentine belt which is already spinning to run your alternator, power steering pump, and other things. So having your AC on does nothing to fuel economy.

  • Accually by running your AC Compressor you are adding load onto your serpentine belt system. This load requires more engine power to run.

    Generally 4 cylinders are more prone to use more fuel to turn a AC compressor just due to the lack of torque. On a V8 engine running your ac is barely noticable.

  • Give us Hydrogen Bitch !!!

  • lol i thought this was gonna be about how the make the car more fuel efficient. o well, ill remember these things when i start driving

  • lmao gas droping fricking 124 in canada

  • wrong: gas prices dropping. LOL that was in the old days.

  • gas is up and up now

    where I am it is $3.90 - $4.40 (dep. on grade and station)

  • *sigh* people like you complain about high gas prices. Try going to Europe for a week. Gas there is the equivalent of 10-12 dollars a gallon.

  • That true... Americans think that the gasoline's prices in USA are very high, but prices in Europe are much higher. And I can't understand why Americans are using car with huge engines that uses a lot of gasoline. Try to drive European cars with smaller engines and manual gearboxes. You will see how much money you can save. :]

  • Yeah. I wouldn't like the tiny cars. But a cavalier 5 speed would be perfect for me. 34 mpg is good enough for me. :P

  • We Americans don't know how to drive a stick very well.

  • speak for yourself cuz u dumb if u havent learned.....

  • Louie90032 Shut the fuck up and move on with life.

  • thats right lame capital L.....

  • Shut the fuck up already

  • if u cant take the criticism get the fuck outta here...the "reply" button is there for a reason....

  • No you get the fuck out of here, you cock sucking asshole.

  • ok u got me mistaken for ur mom...she likes it when i cum on her face....

  • How Immature of you telling Mom jokes on The Internet. Seriously, get a Real life and Stop Replying to me.

  • yeah, in europe huge engines aren't bigger than 3.5 litres. i get really impressed when i see in youtube those muscle cars DOUBLING that capacity

  • in usa, I regularly see people with engines over 5 liters, particularly in trucks that are rarely pushed even close to their capabilities

  • listen, number one thing: engine load

  • There are some good tips here. For more tips do check out the 'Alternative Fuels' video in Youtube.

  • i would say learn how to make money, then do whatever you want with your car!!!!

  • Apparently Tuesday is that cheapest day to buy petrol.

  • "gas prices go down more than they go up" where do you live?

  • lol I want to know as well, and i like how she says "and if you want to get the best price for gasoline, keep an eye on the big price signs out front" ...really? it all makes sense now! *end sarcasm*

  • She's using the metric system, probably Canada since she doesn't really have an English accent.

  • What if I need to go farther than 7 miles in a day?

  • Same rules apply.

  • Hey petrol canada gas is way more expansive

  • also buy gas before the sunrise, the gas expands when it gets warm, so buy it when its cool and you will be charged less

  • does it matter really gas is stored underground alot cooler than a summer day

  • When she say gas prices go up more often than they go down, she doesn't mean gas prices go down more significantly, only more often.

    Read better!

  • so what, shes still wrong. gas prices have been doing UP every day for the past 3 months.

    Learn better!

  • buy a car that runs on natural gas ,it's lots cheaper and you can fill up at home.

  • Ideling does NOT use alot of gas.. an 8 cylinder car can idle on a full tank of gas for almost 2 days.

  • yah right gas prices drop more often than they go up?? lol more like other way around!!!

  • yah right gas prices drop more often than they go up?? lol more like other way around!!!

  • lol how old is this vid. i see gas prices going up more than down.
