Civic bad fuel economy..

[Kienn.]

Hey guys ! I've purchased a civic fd1 earlier this year and i've recently noticed that my fuel economy has declined dramatically over the past couple of weeks. Im averaging about 350km's in a single tank, i occasionally vtec here and there but that shouldnt explain the high fuel consumption. Could it be the oxygen sensor that need replacing ??? Any help would be greatly appreciated :D

[black8thgen]

o2 sensor is common fix. also check ur air filter in the intake box.. if thats dirty and clogged up ur fuel consumption gets raped

[SHOGUNOVDDRK]

Different fuel going in?

Due for a service even?

[xenonkuraz]

no vtec'ing

[Kienn.]

Filled up with 98 when i first got the car, but didnt find it necessary to use premium fuel in an average family car. I've stuck with 91 since than and got roughly 500-550kms (average).
Theres still about 3000kms before my next service.. Is it possible to DIY the oxygen sensor?? as i know Honda charge a shitload $$$ for their services

[trism]

No reason not to use 98 in a family car.

Even though its more expensive, you generally get more kms per litre, because its a cleaner, better burning fuel.

As the for economy, common things to look at are oxygen sensor, air filter, and oil.

[xenonkuraz]

O2 sensor is easily replaced. Simply unscrew and disconnect

Pump your tyres up? Lol

[shepparton]

yeea check tyre pressure, tunee up your car, avoid giving your mate a lift ( this can be categoriseed as unneccessary carring heavy load which mean extra fuel needed)

im having a highrev when using a 91ron..

Fitting an exhaust system with too large a diameter will also half your mileage.

[lolmclol]

Lies, a larger exhaust not only increases torque, horsepower, and fuel economy, but also makes you look like a mad dawg when your cruisin' through the 'burbs in your race car yo!

Primary O2 Oxygen sensor usually throws a CEL if there is a problem with it, check it out first. Spark plug should be checked, air filter might be dirty... Service the car..

Would check my O2 sensor as well as i'm not really getting "much" with my single carby eg. if I replace my cluster that has a CEL, would that work or if a car that was fitted (factory) with a cluster w/o a cell, doesn't really have a wiring for CEL? I know, I know it's a noob question.

Yeah hitting i-VTEC in an FD1 means hitting the economy can which improves fuel usage and worsens performance.

So actually you haven't been hitting i-VTEC enough! :)

As above have posted check your air filter and also try removing the neg battery terminal for 10mins. This should set your ECU settings back to default which may help.

[lolmclol]

^ in before someone questions what i-VTECH is in the FD ;D

You must spread some Reputation around before giving it to DuffyFD again. :-p

you're using the wrong terminology

Get the car serviced if really think there is a problem with it, if you can't afford to get the service, or don't want to pay for cost, consider selling the car and buying a bicycle. My experience: car serviced to logbook schedule, driven neither thrashed nor nannered, I've averaged 7.1L per 100km for the past 2 years/33000 km, with an average fill-up distance of 400km; worse performance was 8.5L. Some of the things i do: gentle accel. from a stop, and (if not in traffic) gentle decel. to a stop. Been using 95 RON, for better engine system health and performance (economy only slightly better). As mentioned FD1 vtec is for economy when you're up past 80 keep the revs between 1500-3500.

[threesix]

I've been getting 5.2 on 95ron.

[CrystalSkull]

Yeah but your top speed is 90.

[threesix]

lest it doesnt look like a 4x4.

[CrystalSkull]

Mate my car is for driving, not looking at.

[threesix]

Mines for both! :) Dish gets da bitch.

My FD2 was giving me bad mileage up until the 60K major service (done last week). A tank full used to last for around 300 Km before the low fuel indicator lights up. But now I've driven about 170km since the service and still there's about 60% of fuel left in tank. Didn't know a service could impact that much on mileage. And yeah I drive with a light foot hardly hitting the ivtec

[Stevil]

You light foot drivers you need to give ya motor some curry !!! I''ve knocked 65,000km in just over 15 mths and I flog the crap out of my car daily. When I cruise down the hume hwy I can still get 700+ out the 45 L tank. I change my oil monthly some times more as I track the car and it still purrs like new.

[lolmclol]

I do a range of driving, unfortunately a lot of stop-start, but I get around 600 ~ for 45L. Yeah lets drive like a granny lewl, not.

Your meant to enjoy driving! My passengers say I thrash it, but no one else owns a Honda yo!

[civicer]

Its not that I don't know how to thrash it. The car I had before honda (about three odd months ago) took a lot of abuse from me. Now that we've got our baby on its way next month, I'm trying to behave myself :p

I like this!
Last month I did a cbr melb trip and our model loves the highway. The other night I partook in some spirited driving at the start of a freeway, again the car shone. I'm a newer driver, but a little older than most, so I always have safety in my mind as priority. I think it's rad people go to the tracks to really get the most enjoyment out of their cars. There's a lot of different levels we can enjoy them on, cruising for relaxation, racing for rushes...
