00:00 Drivers in Japan have been using a set
00:02 of habits that dramatically improve fuel
00:04 efficiency.
00:06 Here is the part most people in the
00:08 United States have never heard. These
00:10 techniques became widespread after the
00:12 1970s oil crisis,
00:15 >> [music]
00:15 >> when every drop of fuel started being
00:17 treated as a strategic resource by an
00:19 entire [music] country.
00:21 Now, here is what makes them so
00:22 practical. None of these tricks require
00:25 mechanical knowledge, expensive tools,
00:28 or a single modification to the vehicle.
00:31 They are simple adjustments to the way
00:32 you drive. Habits most American drivers
00:35 were never taught. And once you
00:37 understand the logic behind them, you
00:40 start noticing just how much fuel is
00:42 being thrown away every single day on
00:44 the road. Today, you are going to learn
00:47 14 techniques inspired by Japanese
00:49 eco-driving that [music] can instantly
00:52 stretch your range.
00:54 Some you can apply in seconds. Others
00:57 require a small shift in mindset behind
00:59 the wheel. But together, they form a
01:02 system that can make a single tank last
01:04 far longer than you ever imagined.
01:08 And at the end, I will show you the one
01:10 mistake millions of drivers make every
01:13 day. A habit so common, it might be
01:16 draining more fuel from your tank than
01:18 anything else on this list.
01:21 Let us get started.
01:23 Number 14.
01:24 Long-range vision. Most drivers believe
01:27 they are paying close attention to
01:28 traffic. In reality, they are simply
01:31 reacting to whatever is directly in
01:33 front of them.
01:34 The car ahead brakes, they brake.
01:37 Traffic slows down, they slow down. The
01:40 light turns red, and only then do they
01:43 lift off the throttle. This style of
01:45 driving feels completely normal, but it
01:48 destroys fuel efficiency. Every late
01:51 reaction wastes energy that was already
01:54 paid for at the pump. In Japan,
01:56 eco-driving training teaches something
01:59 different.
02:00 Long-range vision.
02:02 Instead of focusing only on the bumper
02:04 of the car directly ahead,
02:07 you start looking far down the road.
02:10 >> [snorts]
02:10 >> Brake lights three or four cars away,
02:13 traffic signals at the next
02:15 intersection,
02:16 the flow pattern of an entire block.
02:19 When you anticipate these situations,
02:21 you simply lift off the accelerator
02:23 earlier and let the car slow down on its
02:25 own momentum.
02:28 Many times, traffic starts moving again
02:30 before you ever reach the stop section,
02:33 which means you do not have to brake at
02:35 all.
02:37 This single habit cuts the constant
02:39 accelerate and brake cycle that defines
02:42 most American driving. And by itself, it
02:45 can produce noticeable savings on a
02:48 daily commute.
02:49 Number 13, the constant speed principle.
02:53 A lot of drivers assume fuel consumption
02:55 depends mainly on how fast you are
02:57 going.
02:59 In reality, the biggest enemy of
03:01 efficiency is not your top speed.
03:05 It is constant variation. Every time you
03:07 accelerate, the engine injects more fuel
03:10 to generate the extra power.
03:13 Every time you brake, that energy is
03:15 simply wasted as heat in the brake pads.
03:19 This is why experienced eco-drivers
03:22 focus on holding a steady speed.
03:24 On the highway, your right foot should
03:26 be as stable as possible. No constant
03:29 micro-adjustments.
03:31 Going up a slight incline, do not press
03:33 harder on the pedal. Let the car lose a
03:36 little speed naturally. When the road
03:38 levels out, the vehicle will recover
03:41 that speed without demanding extra fuel
03:43 from the tank.
03:45 If your car has cruise control, even
03:47 better.
03:48 Cruise control makes those
03:50 micro-adjustments far more efficiently
03:52 than almost any human driver could.
03:55 Stable speed means less wasted energy
03:58 and more miles per gallon at the end of
04:00 every trip. Number 12.
04:02 Efficient acceleration. There is a very
04:05 common myth that says accelerating
04:07 gently always saves fuel.
04:11 In practice, [music]
04:12 that approach can actually make things
04:14 worse. When you accelerate too slowly,
04:17 the engine spends a longer stretch of
04:19 time in an inefficient operating range,
04:21 working harder than it needs to and
04:23 burning more fuel in the process.
04:26 The right approach is progressive,
04:28 purposeful acceleration.
04:31 When the light turns green, accelerate
04:33 firmly but smoothly.
04:36 Not aggressively.
04:37 Not sluggishly. The goal is to reach
04:40 your cruising speed quickly, then ease
04:43 off the throttle and ride the momentum.
04:46 In other words,
04:47 short and efficient bursts of
04:49 acceleration.
04:51 The faster you move the engine through
04:53 its least efficient phase, the better
04:56 your overall fuel economy will be by the
04:58 end [music] of the day.
05:00 Number 11.
05:03 The engine's [music] sweet spot. Most
05:05 people pay attention only to the
05:07 speedometer, but the real story of fuel
05:09 consumption is happening inside the
05:11 engine itself.
05:13 Every engine has an RPM [music] range
05:15 where it operates at maximum efficiency.
05:18 Outside [snorts] of that range,
05:20 >> [music]
05:20 >> it starts wasting fuel.
05:22 If the RPMs run too high, the engine
05:25 burns extra fuel just to maintain a
05:28 given speed. If the RPMs run too low
05:30 under load, the engine struggles and
05:32 consumes [music] more as well.
05:35 The trick is to keep the engine sitting
05:37 comfortably in its optimal range.
05:40 In a manual car, that means shifting up
05:43 earlier instead of letting the engine
05:45 wind [music] out.
05:46 >> [snorts]
05:46 >> In an automatic car, it means using
05:49 smooth, moderate throttle inputs so the
05:51 transmission upshifts quickly into a
05:54 taller gear.
05:56 A comfortable engine uses less fuel. A
05:58 stressed engine uses more. The principle
06:01 is that simple.
06:03 Number 10.
06:05 Tire pressure control.
06:07 This is one of the simplest tips on the
06:08 entire list and one of the most ignored
06:11 [music] by American drivers. Tire
06:13 pressure drops over time and most people
06:16 never notice because the loss happens
06:18 gradually. The car still drives
06:20 normally. The handling feels fine. But
06:23 fuel consumption starts climbing without
06:26 any obvious reason. Under-inflated tires
06:28 increase rolling resistance. The engine
06:31 has to work harder [music] to keep the
06:32 vehicle moving at the same speed and
06:35 that means more fuel is being burned for
06:37 the exact same [music] trip.
06:40 The right approach is to check tire
06:42 pressure regularly.
06:44 Always when the tires are cold.
06:46 Preferably first thing in the morning
06:48 [music] before driving anywhere.
06:50 That gives you an accurate reading.
06:52 Properly inflated tires reduce engine
06:54 load [music] and improve efficiency
06:56 immediately. Sometimes by several
06:58 percent on the very [music] next tank.
07:01 >> [snorts]
07:01 >> Number nine.
07:02 The unnecessary weight rule.
07:04 Another common mistake is driving around
07:07 with a steady load of extra weight
07:09 without realizing it is even there.
07:12 Everything inside the vehicle affects
07:13 [music] fuel consumption. Because at the
07:16 end of the day, the engine has to move
07:18 every single pound of cargo down the
07:20 road. The problem [music] is that this
07:22 weight usually accumulates from small,
07:24 forgettable items that build up [music]
07:26 over weeks and months.
07:29 Tools left in the trunk after a project.
07:32 Cardboard boxes that [music] were
07:33 supposed to come out yesterday. Sports
07:35 gear from last season.
07:37 Travel items from a trip 3 months ago.
07:40 By the end of the year, many drivers are
07:43 hauling dozens and sometimes [music]
07:45 hundreds of extra pounds around their
07:47 daily route for no reason at all.
07:50 Every acceleration requires more [music]
07:53 energy to move that extra mass.
07:56 That extra energy comes straight out of
07:58 the fuel tank. Keeping the car lighter
08:01 reduces engine effort, especially during
08:03 starts and accelerations, and over time
08:06 the small optimizations turn into real
08:09 savings.
08:10 The most interesting part is this.
08:13 None of the techniques on this list
08:15 require a single dollar of investment.
08:17 They only require awareness.
08:20 And this is only [music] the beginning.
08:24 Number eight.
08:26 The aerodynamic drag factor. Once your
08:28 vehicle reaches higher speeds, an
08:31 invisible enemy starts playing a major
08:33 role in your fuel consumption.
08:36 Aerodynamic drag.
08:39 At low city speeds, vehicle weight is
08:41 the dominant factor in efficiency.
08:44 But once you hit the highway, the air
08:47 itself becomes the main force [music]
08:49 holding the car back. Modern vehicles
08:51 are engineered for years inside wind
08:54 tunnels to slice through the air with
08:55 minimal resistance.
08:57 But small additions can ruin that
08:59 careful engineering in an instant.
09:02 Roof racks,
09:04 cargo boxes,
09:06 bike mounts on the trunk. All of those
09:09 increase drag. And even when they are
09:11 completely empty, they still hurt
09:14 efficiency every mile they ride along.
09:17 The faster you drive, the bigger the
09:19 penalty becomes. At highway speed, the
09:21 engine has to work significantly harder
09:24 just to push the vehicle through the
09:25 air.
09:27 Removing those accessories when they are
09:28 not actively in use allows the car to
09:31 return to its optimal aerodynamic shape.
09:34 That alone translates into real fuel
09:37 savings, especially on a long road trip
09:39 across the country.
09:42 Number seven.
09:43 The smart choice between AC and open
09:46 windows in daily driving.
09:48 The comfort question usually comes down
09:51 to two options.
09:53 Roll the windows down
09:55 or turn on the air conditioning.
09:59 A lot of drivers believe the AC [music]
10:00 always burns more fuel. That is not the
10:03 full story. At low speeds, like in city
10:06 traffic, [music]
10:07 driving with the windows down is more
10:09 efficient. Air flows in naturally and
10:13 the engine does not have to power the AC
10:15 compressor.
10:16 But everything changes the moment you
10:18 reach the highway.
10:20 At higher speeds, open windows disrupt
10:22 the air flowing around the body of the
10:24 car, creating turbulence and a
10:26 measurable increase in [music] drag.
10:29 The engine has to work harder to
10:31 overcome it. In that scenario, running
10:33 the AC with the windows closed is
10:36 actually [music] more efficient.
10:38 The rule is simple.
10:40 Windows down in the city.
10:42 AC on the highway.
10:44 Before we get into the most surprising
10:46 techniques on this list, hit the like
10:48 button and subscribe.
10:51 We did serious research for this video
10:54 and that small tap on your screen tells
10:56 us to keep producing content like this
10:58 for you. [music] We have plenty more
11:00 fuel saving secrets coming your way.
11:03 Number six.
11:06 Idle time awareness.
11:08 Leaving the car running while sitting
11:10 still feels harmless. [music]
11:13 Waiting for someone in front of the
11:14 house. Sitting in a long drive-thru
11:17 line.
11:19 Warming up the engine on a cold morning.
11:22 But the reality is that the engine is
11:24 burning fuel the entire time without
11:26 moving the car a single inch.
11:30 Modern engines do not need long warm-up
11:32 periods like older vehicles from the
11:35 1970s and 1980s did.
11:38 In most cases, [music]
11:39 the best approach is to start the engine
11:42 and begin driving smoothly right away.
11:44 Every minute spent idling is fuel burned
11:47 with zero return on investment. Over
11:49 weeks and months, that adds up to a
11:52 significant waste. If you know you are
11:54 going to be parked for more than a
11:56 minute, shutting off the engine is the
11:58 smartest move you can make.
12:01 Number five, choosing the right fuel.
12:05 There is a stubborn myth that says
12:07 premium [music] gasoline always improves
12:09 performance and efficiency, no matter
12:11 what car you drive. That is simply not
12:13 true.
12:15 The actual difference between regular
12:17 and premium fuel comes down to the
12:19 octane [music] rating, which is just a
12:21 measurement of resistance to knocking
12:23 inside the cylinder. High-performance
12:25 [music] engines and certain turbocharged
12:27 vehicles genuinely require higher octane
12:30 fuel.
12:32 But the vast majority of vehicles sold
12:34 in the United States are designed to run
12:36 perfectly well on regular gasoline.
12:40 Using premium fuel in a car that does
12:42 not actually require it will not improve
12:45 fuel economy.
12:47 It will not improve performance.
12:49 You are simply paying extra at the pump
12:52 for no measurable benefit at all.
12:54 Japanese drivers follow the owner's
12:57 manual strictly on this question. And
12:59 that is exactly what every American
13:02 driver should do. Number four,
13:05 the importance of [music] the air
13:07 filter.
13:08 Every engine needs a balanced mixture of
13:11 air and fuel [music] to operate
13:13 efficiently.
13:14 A lot of drivers forget that the air
13:16 side of that equation matters just as
13:18 much as the fuel side. The air filter is
13:21 what keeps dirt and debris [music] from
13:23 entering the engine.
13:25 But over time, that filter becomes
13:27 clogged with dust, pollen, and grime.
13:31 When that happens, air flow into the
13:34 engine becomes restricted. What does the
13:36 engine do in response?
13:38 It compensates by burning more fuel to
13:40 [music] produce the same amount of
13:42 power.
13:43 The car keeps running like it always
13:45 has, just less efficiently with every
13:47 passing mile.
13:49 Checking and replacing the air filter on
13:51 schedule is one [music] of the cheapest
13:54 maintenance items in the entire vehicle,
13:56 and it has a direct, measurable impact
13:59 on fuel economy.
14:01 Number three.
14:03 Fuel cap sealing. Most drivers never
14:05 think twice about [music] the gas cap,
14:07 but that small piece of plastic plays an
14:09 important role in efficiency.
14:12 Modern vehicles [music] use a fully
14:14 sealed fuel system designed to prevent
14:16 fuel from evaporating.
14:19 If the cap is loose, cracked, or has a
14:22 worn out rubber seal underneath, fuel
14:24 vapors can escape [music] into the air
14:26 every single day the car sits in the
14:29 driveway.
14:30 It seems minor at first, but over weeks
14:33 and months, those small losses turn into
14:36 real money disappearing from the tank. A
14:39 failing cap can also trigger the check
14:41 engine [music] light on the dashboard,
14:43 which sends a lot of drivers straight to
14:45 the dealer for an unnecessary diagnostic
14:47 [music] visit.
14:48 The fix could not be simpler.
14:51 Tighten the cap until it clicks every
14:53 time you fill up. Check the rubber seal
14:56 for cracks or hardening twice a year.
15:00 Number two.
15:02 The quarter tank rule. Some drivers
15:04 treat the low fuel light like a personal
15:06 challenge, trying to push the tank as
15:08 close to empty as possible before
15:10 filling up.
15:12 That habit can actually create long-term
15:15 problems for the vehicle.
15:17 Inside the gas tank, there is an
15:19 electric fuel pump that is cooled by the
15:22 fuel surrounding it. When the level
15:24 drops too low, that pump can start
15:26 pulling in air along with the gasoline,
15:28 which causes additional wear over time.
15:32 There is another problem at low fuel
15:34 levels.
15:35 Sediment and debris settle at the bottom
15:37 of every tank, and the lower the fuel
15:39 level drops, the more likely those
15:41 particles are to be sucked into the fuel
15:44 line and the filter. Keeping at [music]
15:45 least a quarter tank in the vehicle
15:47 protects the fuel pump and helps you
15:49 avoid expensive repair bills down the
15:52 road.
15:53 Number one.
15:55 The calm lane strategy.
15:58 In heavy traffic, a lot of drivers try
16:00 to save time by constantly switching
16:02 lanes.
16:03 The idea is always to pick whatever lane
16:06 looks fastest at the moment.
16:08 In practice, that habit dramatically
16:11 increases fuel consumption. Every lane
16:14 change requires acceleration to get into
16:16 a gap, followed by another round of
16:19 braking when that lane slows down again.
16:22 The cycle repeats over and over for the
16:25 entire commute.
16:27 Multiple traffic studies have shown that
16:29 drivers who constantly switch lanes
16:32 rarely arrive much faster than drivers
16:34 who simply stay in one lane and let the
16:37 road flow naturally.
16:39 The time difference is usually minimal,
16:42 sometimes only one or two minutes on a
16:44 30-minute drive.
16:46 But the fuel consumption difference can
16:48 be significant. Maintaining a smoother,
16:50 more consistent driving style with fewer
16:53 lane changes preserves momentum and
16:55 [snorts] reduces the load on the engine.
16:58 At the end of the day, that translates
17:01 into one thing.
17:03 More miles per gallon. On every single
17:06 tank.
17:08 If any of these techniques saved you
17:10 money at the pump or showed you a habit
