Do a compression check on the cylinders. They should all be within a couple of psi of each other. If one or more are reading 10 or more psi higher than teh rest the head gasket is blown or you have a craked block or head.

My Mazda Demio. 1.3 is using too much petrol


Okay- thanks for the public announcement;...just kidding!
Mike it sounds like you have a heavy foot on the gas pedal- speeding around town- Ohhh, I gotcha' again! Or someone is pilfering your gas by siphoning it out; LOL

Okay, all kidding aside, the following issues can cause poor fuel economy:
  1. Incorrect tire pressure
  2. a bad or malfunctioning oxygen sensor
  3. dirty or plugged air filter
  4. dirty or malfunctioning fuel injectors
  5. improperly working spark plug(s) e,g. misfires or improper gap
  6. poor driving habits, like sudden accelerations
  7. engine idling for inordinate or extensive amounts of time
  8. and as silly or unbelievable as it might sound, the type of motor oil...the viscosity that is used can affect gas mileage by up to 10-12%; regular oil changes using synthetic or manufacturer recommended oil that reduces friction should be employed.
  9. Defective coolant sensor
  10. Defective thermostat
  11. a leak in the intake manifold or EGR
  12. Poor compression- If you are driving a car that has high mileage, over 100,000 miles, affects fuel economy
  13. clogged catalytic converter or some other restriction in the exhaust system
  14. Dragging brakes
  15. slipping clutch or transmission
  16. Lugging around excess weight in the car
Any single one of...or combination of the above, could greatly reduce engine performance and affect gas mileage.

What happen when I remove out the thermostat?


the thermostat opens and closes to allow the coolant to flow in when it's supposed to and out to cool the engine and keep the engine temperature steady. The part is there for a reason and purpose. I would replace it before you have an issue.

Hi


As far as the review says the mileage should not falter since it is new as you said. However

These are the causes of a poor mileage in a car:-


Poorly Inflated Car Tires

Car tires that are improperly inflated create significant road resistance and drag on a moving car. A car engine has to work harder to propel a car forward due to this increased tire/road resistance. This resistance chips away at a car's gas mileage.


Dirty Air Filter

A dirty air filter impedes air flow into a car's engine, a process that disrupts normal engine combustion and makes it less efficient. This causes a reduction in both engine performance and gas mileage.


Bad Spark Plugs

Spark plugs are responsible for igniting a car's air/fuel mixture, an event that causes a mini explosion inside a car's engine cylinders. Bad or dysfunctional spark plugs don't fire, or ignite, properly; thus, they affect engine combustion negatively, which in turn negatively affects gas mileage.


Bad Oxygen Sensors

For a car to be at its most fuel efficient, its oxygen sensors, small and electronically operated, automatically adjust a car's air/fuel mixture and have to be functioning properly. Bad oxygen sensors cause abnormal air/fuel mixture ratios, a condition that results in poor gas mileage and poor vehicle performance.


Leaky Fuel Injectors

A car's fuel injection system is responsible for injecting precise amounts of fuel into a car's engine cylinders, where it is combined with air and ignited. For a car to perform properly, a specific amount of fuel has to be injected by each fuel injector into each engine cylinder. A leaky fuel injector wastes fuel by leaking it outside the engine and reducing the amount of fuel that makes it into the engine. This results in wasted fuel and reduced gas mileage.
It is suggested to start with a code scanner to find out if there are any stored fault codes in your car.

What are the symptoms and causes of a cloged catalytic converter


Symptoms are rough running, stalling, poor gas mileage, and especially a strong smell of rotten eggs (sulfuric acid). The main cause is old age, but poor/cheap/contaminated fuel can also be a contributing factor.

POOR GAS MILEAGE


Have you changed the fuel filter? I know it sounds weird but a plugged filter will make a truck use more gas. The computer tries to compensate for less fuel by commanding the injectors to open longer. Also a plugged filter will cause excess back pressure on the fuel pump making it loud.. Good Luck.

Strong gas smell and poor gas mileage


If the gas odor is coming from the engine, than the problem is most likely a cracked or poorly seated fuel injector.
