High fuel consumption , even after changin plugs/filter/Eng.oil/cvt gear oil and cleaning the throtle

There could be several reasons why your Daihatsu Terios is consuming too much fuel. Here are some possible causes and remedies.Driving habits: Your driving habits could be the cause of the high fuel consumption. Aggressive driving, speeding, and rapid acceleration can all increase fuel consumption. To remedy this, try driving more conservatively and avoid sudden stops and starts. Tire pressure: Low tire pressure can increase fuel consumption. Make sure your tires are properly inflated to the recommended pressure levels. Air filter: A dirty air filter can cause the engine to work harder and burn more fuel. Replace your air filter regularly to keep it clean and functioning properly. Fuel injectors: Dirty or clogged fuel injectors can cause the engine to burn more fuel. Have your fuel injectors cleaned or replaced if necessary. Oxygen sensor: A malfunctioning oxygen sensor can cause the engine to burn more fuel than necessary. Have your oxygen sensor checked and replaced if needed. Spark plugs: Worn or dirty spark plugs can cause the engine to run inefficiently and burn more fuel. Replace your spark plugs regularly to keep them functioning properly. It's important to have your vehicle inspected by a qualified mechanic to determine the root cause of the high fuel consumption. By addressing the underlying issue, you can improve your vehicle's fuel efficiency and save money on gas in the long run.

Adding fuel to the fuel tank is absolutely unrelated to to any change in engine oil pressure.
The oil pressure will be higher when the engine oil is cooler and lower when the engine oil has warmed up.

If you are experiencing abnormally high oil pressure on start up I suspect you are running the incorrect type and grade of oil in the engine. Only use the oil specification(type and grade) listed by the manufacturer for your engine and nothing else.. If you are unsure what that is then it is specified in your owners manual for the vehicle.

High fuel consumption has also nothing to do with your engine oil pressure. If you are experiencing high fuel consumption then please read and examine these factors..........................
Finding and Fixing the Causes of Poor MPG

check for codes and data readings. check O2 sensor readings, is the thermostat tired and not working properly, this can cause high fuel consumption. take a close look at who and how the car is being driven.

IN order to improve fuel consumption you must make the engine run more efficiently. here are the most important ways.
typical maintenance. (check the manual)

1. check air in tires
2. oil and oil filter change
3. spark plugs change (TUNE UP)
4. air filter change


you personally can do most of these things. go to local walmart and get most of these items. very easy.

good luck.

Hi Samuel, Have a diagnostic scan carried out on the vehicle. If it does not record any faults have a service carried out, making sure to replace the fuel filter, air filter, oil filter and to use a good quality engine oil. Have the spark plugs replaced and a full tune up carried out. Your problem has no easy answer. An increase in fuel consumption can be for many different reasons. If the fuel filter has become partially blocked you will press your foot harder to get the required performance. It can be related to brakes binding, or worn wheel bearings. An increased fuel consumption can be related to different tyres with different tread patterns having been fitted or even incorrect tyre pressures. It can be related to bad wheel alignment. It can be related to a greater load of out put on the alternator or AC compressor output load. Let me have some more details and we'll see what we can check and hopefully solve the problem.

Faulty or blocked fuel pressure regulator?

it sounds like your transmission is slipping. they make this chemical you can get at a part store, its a transmission stabalizer. it should help with the grinding noise and transitions to the other gears. also give your truck a complete tune up (oil change, fuel and air filters, spark plugs etc.) it should help with the fuel consumptions.

Have you changed the fuel filter lately? If not do so. Sounds like fuel restriction. Filter usually on frame rail passenger side. Good luck!

Tune up, Change oil, Wires, plugs,PCV, Air filter

Replace the air flow meter.That will cause you to use a lot of fuel.
