how do i know if it is time to change my air filter and what happens if i dont?

Question

would it also couse your car to turn off

Answer 1

it will impact your fuel efficiency as a clogged air filter will effect the amount of air going through the intake and possible changing the air/fuel ratio.

If you take it out and it looks cruddy... replace it. They arent very expensive, but damaging your fuel system and decreasing your fuel efficiency isn't worth it. Plus, they are relatively easy to change yourself. Don't avoid it.

Answer 2

Definitely change it at least once a year. Getting less air will cause many cars to 'burn rich'...you would see blacker, sootier smoke sometimes and definitly use more gas than you need to. Hold your hand close to the end of the tail-pipe while it is running and then smell your palm. If you smell raw, unburnt gasoline, a tune-up (including a fresh air-filter) will increase your milage. If your car is turning off a tune-up might be a good first step for you to get it in order.

Answer 3

no it won't cause your car to turn off but you will start having some problems with it. You should change the filter with your oil or you could upgrade it get the kind that doesn't need to be changed but just cleaned, they cost a little more but in the long run they are sooo worth it because you don't have to keep buying a new one and they improve horsepower and gas mileage.

Answer 4

from personal experience, change air filter every time you change your oil, or at least every other time. when you put in a new air filter in your car or truck, look at the color of the element. it will be bright white, after changing your oil inspect it if it look dingy or black it is time to change. if you drive in dusty conditions you will have to change more often. now as for what happens if you don't change, you will lose fuel economy and your engine will work harder to bring in more air to run. i hope this helps.

Answer 5

Look at the filter and if it looks dirty put a new one in. If you dont change it you'll use more fuel and eventually the engine will stop working and be a great excuse to snog the person in the seat beside you

Answer 6

It's always a good idea to check your air filter when you get an oil change. A lot of places will check it for you. Not getting it changed can decrease your fuel economy.
