AVEO NOISY ENGINE noise

[Car_man]

Hi like to check with aveo owner does your engine sound very noisy like a diesel automobile and feel very rough engine running? My engine sound become like that after doing my 40k servicing and after i took out my resonator.Any solution to make the noise reduce and smoother? Pls Help

What's your oil that you are using. Most of us realize that using 10W30 and below will make the Aveo engine very quiet.

[Kianbeng]

10W30? Would that mean the changing interval needs to be shorter? Or still can tahan 10-15K?

[Genie47]

Can tahan 10k lah!

You got to be kidding ! The thinner the oil, the noiser the engine ! Common sense ! Diesel engine use thick oil, i.e. SAE80 or SAE 20W50 at least ! Thicker oil would increase pressure on hydraulic lift thus resulting in quieter engine but engine drag increase ( loss of power ) resulting in higher FC !

Nope. Diesel is inherently noisy and you can't compare with the petrol engines of ours. The Aveo guys are mostly using 10W30 and 5W30. The engine is very quiet below 3000RPM. Floor the throttle and the engine sounds angrier to the delight of many.

i'm using mobil 5W50.Dunno y the engine sound so rough.Any way to make it smoother or is there any problem with engine

[Genie47]

Nothing is wrong with the engine. 5W50 robs it of power.

Swap out the Aveo engine with a V6 - sure quieter one.

 

Small engine, sure noisy one - it really depends on your own expectations. If you are used to a a 2.L Inline 6 or a V6, anything less...sure noisy..no matter how thick your engine oil lor..

HAHA if got money sure buy A higher CC car. My AVEO 40K Disc rotor warp,brake pad uneven and transmission leak.Ask Starsauto y so fast spoilt and they can't give me an answer but

subsidised all the repair after i complain to the manager.This Aveo give a lot of problem but what to expect cos the car is cheap

[Car_man]

IS it true using 5W30 make the engine quieter?Smoother? If that the case next servicing i will change to that

[Genie47]

Check with the rest of the Chevy guys who converted. It is smoother. The engine's tolerances and clearances are tighter and hence the reason why 30wt is good.

[Car_man]

So it will make the engine smmother but will it reduce the engine noise?

[Genie47]

A smoother engine has reduced engine noise.

Try mobil 1 gold, 0w40, FC improve, feel it gives more power and most of all i felt engine is smoother and quieter.

[Genie47]

Its still going to suck power out of a meagre 1.4L engine lah! 10W30 and below is the way to go. Right now, with 10k OCIs, M1 Gold is damn expensive for that kind of interval. With cxxxxxe and Schaeffer's selling 30wt oils so affordable, that's the way to go.

[Car_man]

But is cxxxxxe the same quality as Mobile !. Afraid later engine largi worse

[Genie47]

Please lah! Its just a damn car! It doesn't care if you give it cxxxxxe or Mobil 1, it only cares if there is enough oil to generate oil pressure! And no, Mobil 1 does not have a 30wt oil available. Just use whatever 30wt you can find be it cxxxxxe or Schaeffer's or RP.
