I noticed that my fuel economy has gotten really bad from the time I bought my car till now. When I bought it last year I was averaging close to 500kms but now I'll struggle to even get 380kms. I've changed my air filter to a K&N panel filter but havnt noticed much difference. I've bought a new fuel filter and am yet to fit it. Any other suggestions as to what it can be? I don't drive my car hard either.
Thanks Matt

What was your fuel usage in litres per 100km? What is it now?

lots of things can affect your fuel economy, a common one on AU's is too high fuel pressure.

come back to us once you find out your actual L/100klms fuel economy and have done a basic service (oil/oil filter/plugs/fuel filter/ecu reset)

Did you clean the air fliter, clean the throttle body and put new plugs in?
Also how did you find the L/100km. Did you fill it, reset trip meter, drive until your empty, fill up, take note of KM travelled, take note of L used to fill and do the calc to find it? Or just go, oh I got 350km to a tank once, and this is the L/100. You cant do it like that or you will never get a true indication. My bet would be oxy sensor, plugs and air filter. Clean filter and change plugs and oxy sensor, and do the L/100km test and see how it goes. Also what kind of driving is it, city or highway. Id get 350 around the city too, thats how cars are with city driving.

Well I based it on the average which was is 380 and did it on the online calculator and that's what I got. I'm not sure if you guys read the first post properly but I did mention I got a K&N panel filter which is new.

You cant get a L/100km like that. How many L did it take to fill the car once the 380km was driven? You are leaving wayyy to many variables. Do it the way I said, and then come back at us with a proper consumption figure, and we can help.

A "tank" can be anything from 50 to 70 litres. The DTE on the screen varies according to driving conditions and can be highly inaccurate in city/suburban style of driving. It is generally more reliable on long distance trips. Unless you keep a record of actual litres used and distance travelled anything that is offerered is purely conjecture. |
