Dear all sifus,

just wonder does anyone has civic fc, mine is year 2017, now my car the fuel consumption (FC) quite high, previously usually hangs around 16km/l, but currently its 10km/l to 12km/l max. wonder anything i could check to know the reason behind high FC?

second would that when going on uneven road, there would be 'thump' sound near the rear left of the car. but when going through a hump, it doesnt have the 'squeeking' sound, but recently i have changed the rear bearing and it happened after few month after changing the wheel bearing.

thanks all for the inputs!

Civic weakness - Lower arm bushes & absorber prone to fail (Confirm fail after few years of usage due to stupid bush design in it)

fuel consumption high? Check your tires air pressure, air filter, spark plugs condition and also what engine oil you use during your last change.

check for carbon build up on intake valves too

do you know how much would it cost to change the bush and labour?
and which workshop if you can introduce.
thank you.


noted, thanks for the advise

why not go back to the same workshop that changed your wheel bearing and ask them to check the sound

Bush and suspension issue.

Thanks all for reply

Full disclosure mine is a model 2021 civic fc 1.5 tcp (last batch).

My fuel consumption lowest is 9.7km/l and 10km/l (highest). Currently, is 9.7km/l.

Driven waja, pesona, polo, passat, c200, glc 200, can safely say civic fc is sluggish and not very responsive. Then again, once its driving smoothly on highway, its okay.

For short distance, where you expect a lot of stops, traffic or bends, i drive between 1-1.5k rpm.

For straight road or road is clear, i will let it go up to 2k rpm before i accelerate further.

The acceleration work best staggered rather than sudden acceleration, example going from 1k rpm and you step hard on peddle and it rav all the way up.

Not a car person but that's my observation.

you are driving an CVT, mind you.

Ya, am minded of that. Am adapting to it, which explains the fuel consumption. I keep reminding myself, it's a family car, not a high performance car. I've seen tones of comments/feedback on the CVT engine.

thanks for the feedback. the reason behind im asking is that i used to get around 15km/l mostly city drive, and also the reason i got such number because i pick the time on my travel, hence i manage to get the number i mentioned.

im somehow light footed when i drive except when i got frustrated then i might be heavy footed.

i think due to the damper/absorber issue it f*** up my fuel consumption and hanging around 9-11km/l.

the Civic 1.5 Turbo engine is extremely efficient if you are driving on the highway. can easily get 15 km/l
if you are stucked in traffic, every car will suffer

BTW, what is the mileage on your car? ever washed the throttle body?

agree with you on the efficiency of the turbo engine. i got 20km/l from penang back to KL.

160k km, i dont think i have done washing the throttle body

These 2 famous for slow grandfather's drive sluggish acceleration wo, especially I owned Polo Sedan 1.6 before. Friend brother's Passat 380 he said the acceleration also slow and need press pedal deeper before it gets responsive...

Didn't know Civic FC so bad on this aspect...

Bought the VWs in 2012. Boi those were the good times until the gearbox problems, the number of times dropping by Sg Besi Vw and the service bills came up to rm 2k+. It was time to call it quits. 🤣

Polo 1.2 TSI hatchback - https://www.carlist.my/used-cars/2012-volks...chback/12677847 . This car is zipppyyyyy...looks good in black.

Passat B7 CBU, still have it. Heat the seats to get the ball sacks warm. 🤣 Anyway, i think the acceleration is okay.

Different strokes for different folks i guess.

I see, yours Polo 1.2 TSI, then different. 1.6 NA mostly struggling...

Small displacement turbo = turbo lag.

Despite being smaller, less inertia, efficient turbo in modern engine, the lag is still there.
If you driven old school turbo, that is serious even more lag.

As Jason from Engineering Explained said - "Don't lug your engine."

Be it Turbo or NA.

Paddle shift is there for a reason. Downshift 2 gears, before you go.

not necessarily.

the latest Honda 1.5 L15B7 engine would happily disagree. peak torque at 1700 RPM with a CVT that very intelligently anticipates and maintains above 2 to even 3k RPM when you need it (braking, cornering, both up and downhills)
definitely utilizing the car's ESP/VSC systems' sensors to get data fed into the TCU (and ECU)

No, stop clinging to old stuff, newer tech is good enough to reduce turbo lag even on small displacement engine, well set up small turbo = barely noticeable turbo lag

Think of regular guy cruising at steady speed in overdrive. Then simply lug the engine to overtake.

versus another person who downshift to optimal gear before the action.

I'm sure you know the difference.

Braking and corner are usually fine. Car already downshift during corner entrance, plus we don't one shot floor to bottom on corner exit.

Of course certain corner, like should I use 2nd gear or 3rd gear situation, human make better judgement. On high torque, high power car, sometimes short shift 2nd gear, get to 3rd gear early on corner exit is faster especially on slippery road.

Yeah, and I'm telling you modern cars are getting smarter to compensate the lack of driver capability.

Just step on the accelerator pedal it just goes without lugging.

Auto downshift auto RPM spike auto full spool turbo ready to go effortlessly.

Hell, if that's not enough, there's always the S gear on the lever.
Civic FE e spec have no pedal shifts and never at any point of time i ever felt the need of pedal shifter.

This is coming from a hardcore die hard manual enthusiast. And i think that means something.
