⛽👎 7 Reasons for high fuel consumption!!! and how to solve
HTML-код

- Hello everyone today we will see the comon problem of high fuel ⛽ consumption on a car and how to solve it the problem.
Defective fuel injectors
If your fuel injectors are faulty and insufficient fuel is being injected into the engine, your car won’t run efficiently. A less efficient engine means increased fuel consumption.
Clogged air filters
Air filters and oxygen sensors ensure that the ratio of air and fuel going into the engine is correct for optimum performance. If they’re clogged or damaged, the ratio is affected, which can damage your engine and will increase the amount of fuel your car is using.
Faulty spark plugs
If the spark plugs in your car aren’t sparking correctly due to wear and tear or damage, it affects combustion. The result? Increased fuel consumption.
The wrong oil
If you aren’t using an oil that reduces friction or the oil recommended by the manufacturer of your vehicle, you could be paying the price with poor fuel economy.

Don't forget number 8. The cooling system consisting of the thermostat & ECU temp sensor. If the fuel injection computer thinks the engine is still cold it will run a richer air fuel ratio until the engine warms up fully. If thermostat is stuck open then engine will never fully warm up. Check thermostat by running engine from cold & feeling top radiator hose, it should stay cold until thermostat opens & then go to hot to hold. If hose starts getting warm slowly then thermostat is stuck open & needs replacing. Injection temp sensor,(thermistor), needs to be tested for correct reading,(resistance) when engine is warmed up. Also check wiring for sensor by measuring sensor reading from the ECU wiring plug.
Thanks in advance 👍
In countries where we have hot climate we infact remove the thermostat
@@newtonmutea your fan will work overtime and as such, lifespan of the fan will be reduced.
Engine will always not work at it's maximum operating temperature. It's work below ( run cold ) and this will lead to quick wear and tear.
@@newtonmutea that's wrong, the car will consume more fuel than normal due to the delayed engine warming
@@newtonmutea
How hot is your climate there? 50°C whole day?
The thermostat only start openning when engine temp about 68-70°C, normally fully open around 90°C.
1. Fuel injector
2. Air filter
3. Oxygen censor
4. Fuel filter
5. Ignition system( plug and coil)
6. Engine oil
7. Mass airflow sensor
8.fuel leak
Things that reduced fuel efficiency ..and fuel economy .
1.hot wether
2.dirty fuel injectors
3.dirty engine air filter
4 .dirty oxygen sensor
5.cloged fuel fuel filter
6.cloged coils
7.bad spark plugs
8.bad oil viscosity esp thicker oil do regular oil changes
9.dirty mass airflow and mass airflow sensor
How do I fix #1 😂?
@@liquidh5226Just summon a ritual to increase the temperature
Cars need more gas in cold weather.
#1 doesn't apply to cars with air to water intercoolers. I get almost 90mpg at 90f+
Good informative Video, thanks
clean maf helps out back a few more h.p. and runs better.
9. Brake drag. While this is often overlooked and affescts mostly disc brakes, brake drag is a real problem that affect gas mileage.
Happened to my car. You are right.
How do I fix that
@@nays8618 overhaul brake caliper. Replace worn out / damaged parts.
Tire pressure one of the most important items to check regularly if you want to save fuel.
why/how is that related to the fuel, thanks in advance!!!
@@hiyou8823low tire pressure decrease mpg
@@hiyou8823the more air, less drag
@@hiyou8823from your comment I guess you haven’t passed your driving test yet but whenever you do go for the test I wish you good luck.
PS: don’t book the test without learning about Highway Code and vehicle safety though
Too low or too high also wears tires out faster.
Very helpful 👌
#1 You have a hole in your gas tank!
#2 Someone cut your Gas line!
#3 You have an unusually large hole in your engine!
#4 You need to change your 35 year old PCV Valve!
#5 Your Breather box is completely clogged up and so are the tubes connected to it!
#6 Your Mass Airflow Sensor is damaged!
#7 Your 20 year old Air Filter is clogged!
Well explained. Great help to car owners.
That's informative sir ❤
#5 is very important also.
Very brief and informative brother

I had cars ranging from 1.0 to 1.8 and Im always worried about economy but what I learnt shocked me abit. The 1.8 Civic I had was almost the same as the 1.0 Yaris. You would think smaller engines use less but my guess is that they require more revs to get going whereas bigger engines can achieve the same speed at lower RPM. Ofcourse there is a sweet spot ( probably 1.6/1.8 depending on the engine technology ) but there is not much of a difference like mentioned between big/small engines to a certain extent. Ignore those claimed figures, I have almost 20 years of real world experience on about 10 different cars and learnt these lessons.
Bro 1.0 liter I be thinking my 3.0 and 2.4 are small 😂😂😂😂 some people I know have 6 liters
This is the Gospel Truth... I have a 1290cc car consumes same with 1890 Valvematic.. no matter the driving technics I use...even at slow below 20km/h, infact The 1890cc is better on fuel overall.. especially for short distance drives
Yes Everything Correct 👍Also bad and to much widther tyers with to low air pressure in the tyers will take your Counsumption up. ☝
Or wider tires
I am so much interested on this program, I need more lecture on this topic.
Very helpfull thank you, my corsa bakkie is chomping petrol, irs killing me
Number 9 is the most important among all...
Reduce fuel consumption.... Drive conservatively
Good job
You forgot a clogged pcv valve. It doesn't suck in the blowby. Also the incorrect tire psi and carrying too much weight in the car will affect fuel economy
Most new cars have their fuel filter attach with the fuel pump inside the fuel tank. Older cars normally have thier fuel filter outside the fuel tank.
Dealerships trying to get that service money 🤣
The new type of Fuel Pump may have a strainer filter at the bottom, but a finer filter is encased in the filter plastic housing which cannot be remove and clean.
Only way is remove and replace the whole pump set with a new one.
Huh, I'm used to my fuel filters being mounted on the firewall in the engine bay. How old are my cars then? LOL
under car in line on my g.prix. very accessable.
Naw my mercedes nenz is the easyist oil filter i ever changer right after you pop hood it right their
I had an issue the fuel returning house from the engine to the air intake was leaking i wraped up some Teflon tape to make it locked better not to leak
THANX
good
Fuel efficiency can reduce the air with lesser unburn petrol elements .
Indirectly ,this info help a lot for our environment ,since we have so many petrol cars around the world .🧐😐
Do you think 6 km per litre is a fair consumption for a3.0 litre V6 driving with in speed limets
3.0 ford cortina
Screw the environment

It was found that the ethanol-glycerol blend at the ratio of 3:1 (75/25%) can be directly applied as a substitute fuel for either gasoline or ethanol in internal combustion engines in the automotive and power industry😮
mashalla bhai
Enjoyed your informative video. It would be also informative and of interest to the public at large to state the "estimated" general percentage increase in fuel consumption expected for each of the numbered reasons. Also, which is the most common mechanical cause of high fuel consumption i.e. driver or road conditions not in the loop. RSVP Cheers.
I have problem my car over heat to much
Check tire pressure absolutely improve mileage up to 10 percent
Thanx
Sounds like the Tahoe with a 5.3 GM constructed overheating bypass in the fuel system but I wonder what's really going on with mine as it is 22 years old burning a lot of gas
Interesting
What about missing catalyst convertor?
That would actually help your mileage. (Less restrictive air flow thru the exhaust)
One more point - cleaning throttle body
True
My scanner only detect O2 sensors as codes
I have nissan maxima vg30e 1993 is heavy on fuel idling is high and i adjust idling screw to to fullest but idling is 1100rpm and exhsust it got a too much mists and smelling spank water sometimes it revs itself samuel from south africa free state
Dirty intake manifold is a huge cause of high fuel consumption. Clean it as soon as possible.
The terrain and also tire pressure attributes to how your car consumes gas. Those with manual vans ,driving on low gears tend to make your vehicle a guzzler .
as well as how efficient the engine is not all engines have the same efficiency sadly some are better then others
I have Nissan atlas truck 1997, bought in Japan, but it consumes alot what could be the problem
Good mornings i want to find out iam driving c180 kompressor 2010 model w204 does the car having fuel filter and where does it sit
Inside fule tank
@@haileauto if you want to change it must you change the fuel pump aswell or are those components separately
@@haileauto if you want to change it must you change the fuel pump aswell or are those components separately
Normally the internal pump with filter type is to be replace whole set.
@@metzmatu8409 thanks
I like your presentation, but you have to correct one word which is "clocked" into clogged
When my 2002 F150 HD was new it got much better mileage. Why? There was no alcohol in the gas back then. Or only in the Winter. Even with the AC on it still got better mileage in the Summer without the mileage robbing alcohol.
Get New Ignition Coil Packs and Connect to Wires For Spark plugs
They missed ALL items on my own list: 😃
1. Binding brakes. Even the slightest binding will give a noticeable increase in fuel consumption
2. Keep tire pressure at the highest recommended..
3. Do NOT go to wider tires. And only buy tires with "A" or "B" rolling resistance classification (maybe that marking is only used in Europe? )
4. Petrol engines (without turbo) use to have a temperature control valve on the intake of the air filter box, where warm air taken from the exhaust system is mixed with cold air to ensure a constant temperature. Nice thought but the thermostat in the mixing valve tends to get stuck at "fully warm" position over time. Engines tend to lose both power and efficiency when running on hot air. Worth checking 🤔
5. Incorrect toe setting increases rolling resistance. A setting as close to "0" as possible usually gives lowest fuel consumption
6. Clean aerodynamics. Remove all unnecessary stuff like roof racks, caravan mirrors, aftermarket spoilers and wind deflectors..
Vary important
yes
Biggest reason high fule price all over world. High price make every car milage worse.
All of those modifications like sensors, feul injectors and so on, on paper make the car more effiient, but they fail and end up making it less efficient, more expensive to maintain and take up more of our life concerning ourselves with them. I was just doing the maths.
What’s your first language?
Have a 2005 rav4 diesel 2.0
I get 450miles out of a tank
I can't see anyone getting over 360 380
My secret
Accelerate slowly
Always keep at 60mph on national speed limits
Simple 🤣
Engine filter
Fuel injector
Oxygen sensor
Fuel filter
Ignition system
No engine light, hence no codes still very high gas ,2001 Tahoe. I like the previous comment to yours "clean intake" ASAP ? Sea Foam treatment........
My peugeot 3008 giving so much trouble clean everything then I suddenly i have clean intercooler with elbow grease home cleaner ,its problem sort also car speed gone fast.
Thanks my car was wasting petrol I changed sensors and is now ok
I change spark plugs coils fuel injector and solenoid and still got misfire in cylinder 2
I have jeep gladiators brand new I bought it.its drinks a lot of fuel
Firestone? Bias?
My nissan almera is now 500000and it still drive like new as I do service by my self
hm. for me its more the way i drive. ranging from 8l/100km to 13l/100km. depending on acceleration.
What about peogue 406
Dont forget to put 98 in ur diesel truck. It will run very smoothly and last a lifetime 😊
🙂👍
Είσαι θεά
On the opening of the video it shows a I think a sensor can anybody tell me what that is ? Thanks I have two ✌
My 07 Corolla s full tank last 4 hrs used to be more
So is it normal for a 04 Honda to run out of gas quick when driving and hitting a bump?
Totally. They all do that. No worries.
I have a question It saying engine oil pressure low? What can be done to it
Check the oil level. Change oil and filter. If that doesn't fix it, you probably need a new oil pump.
@@spidergoose891 thanks
Another item to be replaced or checked is a bad pcv valve and a carboned egr valve.
Even with no E-light ?
my nissan rogue from 25mpg before and now 15mpg becuz i ah e 325k miles on it and still run and drive😅
You forgot to mention a.clogged or bad non working pcv valve and how often to replace them.
Dalm my 2010 V8 chevy tahoe wastes alot of gas why idk..
The factors are so so many....
I'd your xar is perfectly fine, yhe way you drive matters. You need to step on the accelerator slowly to allow the engine breath. If you drive like a racing car, you'd very to buy mire fuel.
More fuel.... Yes
Dose those 7 things restore the lost engine horsepower over the years?.
I literally replaced all those things or fixed them and I'm still getting shity mileage. 08 Ford Ranger. Like 8-12 Mpg, Fuel flow is avg 1.5+ Gph
100%
10. Worn out transmission that slips more than it grabs. 11. Worn out rings or valve seats.
Fill up your car and park it up at home for a week, you will notice the gauge will still read at full tank, lol
😂👌🏽
I just need help, my car is almost 3 year and it was bought direct. The fuel consumption is something else
😮😮😮😮
How
Hello everyone
I have 4runner 2007 i changed everythimg but still gives me 11 to 12 miles on highway 9 to 10 in city.
What should i do?
there is no electrical problems in the car?
Change car
@haileauto its shows the at tepm light on switch but on computer its shows normal and also battery and check engine light
@@amirkhanahmadzai4963 Sorry if my suggestion to buy new car offend you. Money is very hard here also. Mileage of your car is also ver low compared to here in India. Instead of maintaining a high fuel consuming car, i have sold my previous car, downgraded to a cheaper car with better mileage. I think its more cost efficient. We poor people usually try to keep our car for the longest time although it has already started burning holes in our pocket.
Sell the car 😀
One fact must don't even realise.
After rear rotor change, technicians forget to adjust the hand brake shoes which causes constant rubbing whilst you drive. This acts as if your handbrake is partially activated...causing more fuel to burn.
I've got to cut the emergency brake out of there because I know it rubs and make some noise
@@robertgreatsinger9179
You just need to adjust it...until you can see about 3 treads on adjusting screw for handbrake shoes
What is the possibly fault, when your car spidometer stop working?
Usually it’s the gonqulator bearing under the dipstick.
Put construction nail in fuel line and you can save ⛽️
What is costruction nail and how thissave fuel?

The thing is when have a car the expending of many is crazy exhaust system has so many components and is so f king complicated that is just much better to buy another thing a horse or whatever
🤣🤣
Foult finding power dosen read the gass milouge
pres, regulator, using ethonol gas😢

I bypass the heater core Of an older truck and they gas mileage is cut in half anybody know why?????😂😂😂😂
Don't seven factor ways why fuel efficient

Jesus christ, just give the symptoms, i dont need a documentary.
Fuel injector petrol car
my mas drowns it in fuel unless i unplug it😅 then its fine😂
Change the fuel filter, air filter, synth oil changes 5-7k miles, Lucas fuel (and other) additives….high flow exhaust….tune…or get an EV
Cvt transmission is more better to save $.
Numerous of u guys omit the very very DISTRACTIVE high fuel consumption factor,A DEAD TURBO IS NUMBER 1 WHEN IT COMES TO HIGH GAS CONSUMPTION, TALKING FROM EXPERIENCE.
