My Car consumes more FUEL than ever before, I don't know why? & What do I need to change to use less FUEL ?

Question

What are the exact spare parts that I need to fix this problem?

Answer 1

maybe your answer is ur air intake like filters n such.. worked for me, try it.

Answer 2

You might start with a new air filter, as a clogged or dirty one prevents the proper amount of air from getting mixed with the gasoline. The PVC valve ( positive crankcase ventilation) should be checked for proper operation. Also try cleaning the carburetor or fuel injectors with a good gasoline additive like SEA FOAM...you can get it an auto parts store. Follow the instructions on the can. You didn't mention the mileage on the car.... or whether the car has a carburetor or fuel injection...if carburetor, it may need adjustment, if fuel injection...this is more complicated and usually requires computer hook-up to make the proper adjustments. I'm going to guess that you don't have a lot of experience or knowledge of these systems. The air filter change and cleaner additive is something most people can do themselves, but the additional adjustments will probably need to be done by a reliable mechanic.

Answer 3

Try changing the spark plugs and the air filter, and have the fuel injectors cleaned. If the car's too old or the motor is too big, maybe what you need is a smaller car (or maybe a scooter). Gas is way too expensive these days, and it's not going to get any cheaper.

Answer 4

need to know a couple of things -- year, make, model, and engine size, this would help, but on the other hand, like someone stated before me, the O2 sensor is the trick. a tune up would be good, spark plugs, but on most newer cars that's about it, an oil change is always good, but not going to help with fuel consumption. Good luck Dave (change the O2 sensor, air filter, check tire pressure)

Answer 5

there are a lot of things that can contribute to this. When your tires are low they grip the road more which can cause more gas usage. If it is really hot outside gas can be evaporated. It may also be your fuel intake valve, or air intake. maybe it is just an older car and needs a little more giddy-up.

Answer 6

You need to replace your EGR valve and your O2 sensors. It will help you get the fuel mileage that you're use to get.

Answer 7

Try taking your car to a TRUSTED mechanic and have them evaluate what's going on,and don't be afraid to get more than one opinion.

Answer 8

possibly your oil filter, air filter and check the pressure in your tires.
