alignment of the car seems fine as the tyres wear quite evenly and the steering don't vibrate much as high speed, it is just that the steering is skewed to the left and not straight.

anyone knows what noise is this?



it is coming from the driver side of the engine (nearby to the alternator), went for a quick check at nearby workshop and they suspect it is some pulley/ bearing that is worn out.

If you have done your alignment and balancing, and steering still skewing, perhaps you can check on the power steering bush, this is persona common problem. Otherwise do check your front suspension mounting, might rosak already.

Both of these happened to my persona before.

thanks for your v info.
I went to check at top speed near my company, they quoted me RM 180.today I'll go check at zordaq see see

sounds like the IAFM to me.

okay thanks a lot i will get it checked as soon as possible.

shouldn't be, my intake is already converted to IAFM-less. the workshop tried spraying water at the few pulleys nearby the alternator and the sound kinda got away but came back as soon as the water dries out.

by the way, anyone here has any recommended workshop? i haven't been in KL for a long time so i don't know any reputable shop

G Car Care and Zordaq are quite popular for Campro

How's the review of IAFM-less intake from you? Does it comes with big difference?

thank you, ill give them a try

to be honest i don't feel much difference as my driving style is quite chill and i always aim for best fc, but i would say maybe even slightly smoother power? but my opinion is invalid because the iafm is broken since the first day i got the car.

main difference is i don't have listen to the annoying 'tak tak tak' sound.

I see.. At least there is a way of maintaining the same spectrum of fuel consumption after changing to non-IAFM intake. Thanks a lot!

what are the average fc that u get? my persona with around 50 city 50 highway averages 8-9L/100km (as shown on the meter). pure highway can get around 6+-L/100km.

With 50% trunk road and 50% city driving, my average on meter is usually 7.X litre/100km, spending most of the time below 7.5l/100km.

If purely highway and below speed limit, my persona usually clock similarly with you... Around 6.4l/100km to 6.8l/100km like that.

Mine is a manual tranny by the way..

Lowest average i get on highway is around 5.4-5.6. Speed maintain 90-100kmh. If 120kmh it will go up around 6.2-6.4. If city drive then easily can reach above 8

i'm using persona sv 2014. still ok to use full synthetic oil? cheap fully synthetic oil in lazada. will try shell.
by the way at what age of the car we are not encourage to use fully synthetic oil anymore and have to change to semi synthetic?

I am driving sv 2014 as well. Just change my oil to semi 10w40. This is first time using semi. Mileage 71k. First impression engine felt a bit heavy and fc up. Might change back to fully on next service if the condition is not improving.

Usual rule is if tak makan banyak minyak then boleh pakai. The main concern is would you want or can afford to top up engine oil every time it hits a certain lower limit.

For example I heard it's recommended to check and top up engine oil every time you pump petrol, if you're driving a rotary engine car like RX7. My point is if such burning engine oil is permissible to car like that, then it should be reasonable for campro as long as owner can afford to top up engine oil regularly.

i dont get it. should i just change the engine oil after 10k km. why i do required top up although i do check my engine oil capacity before i travel long journey.

Erm... Think i confuses you. Let me cite an example:

You just serviced your car using fully synthetic oil today.
Your mechanic filled the oil level to second notch of your dipstick (full level engine oil).
You happily driven the car for 480km, or one full tank, then at petrol station when you isi minyak, you check check your engine oil level.
And OMG the engine oil makan sampai half of the dipstick indicator already, in the view that going by this rate, there'll be no engine oil left when you refill petrol next round, so you top up engine oil at petrol station.

Under this kind of circumstances, you have several options:

a) continue this modus operandi until your odometer clocks 10k km and heads to an engine oil change at your trusted workshop.

b) change to a more viscous engine oil, i.e. semi synthetic or mineral, so that oil evaporating rate will be reduced.

c) choose for overhaul, or top overhauled, or change the gasket that's responsible for the burned engine oil. Only your mechanic knows what you need.

On the side note, for Persona Elegance, Proton Centre told me that it doesn't matter i choose semi or fully, my OCI will be 5000km for them. That's why i stick to semi until now. Cheaper to use 5000km of semi synthetic and gain the fc versus mineral.

The fc gain you get from upgrading from semi to fully in my honest opinion does not justify the extra investment you pay for fully synthetic (based on change at every 5000km ya...), so it depends on you how long you want to keep your engine oil in oil sump lo.

Some mat salleh website actually explains that engine oil should be changed as frequent as possible if you can financially afford it, as soon as it detriorate down to a certain limit.

I guess this is the reason why some new model of car, like civic turbo has engine oil quality sensor to measure their OCI.

my persona SV 2014 millage right now about 78k, so should i change the gear & transmission oil?

First post of this thread have an attachment of service schedule to be downloaded. Do check on it.

Change head gasket. Gasket cracked.
