So, 0W20 got see better FC?
Any chance you guys checked the turbo oil hose for sludge like suggested in fb owner club?

I'm using the 5W50 now going 0W40 with the PAO.

Waiting to see flash sale at 2pm...

yeah, crude oil price jatuh, EO also become cheap like it's unbelievable. Last time FS also 2~300 ringgit.

I used to pour Tufoil but now I don't spend extra, just use as is.

I think my CFE is driven quite hard, and very less traffic jam. Average FC is 11L, and coolant temp hits the fan limit quite often.
Adding to that, it's 130k km liao, maybe will have more blow-by, and causing oil thinning.

That in mind, I have the old mindset of using higher vis oil so the oil can tahan the heat. All the while, I err on the higher vis side to be 'safe'. Maybe that's wrong. In a way, whenever I feel like WOT, I can do it with a peace of mind without having to worry about 'what if the xW30 oil cannot take it' in the back of my head. Once a while, I'd do it just to hear the engine roar at 3.5k RPM. Not sure you noticed, mine makes a different howl. Maybe there is a VVT effect after all.



Looking at the oil specs, maybe 5W50 is too thick but with very high TBN.

Yeah, I'm amazed, but they use in-house designed turbo, not like CFE taking a Borg-Warner KP39A.

The front number by lower temp range, the back number by upper temp range.
The smaller the gap between front and back number, the better oil quality (old school thinking).
- For example: 15W40 is better than 10W40.

The Proton recommended oil is similar to generic oil visco chart from last time. Designed using 90~00's rule and technology. Modern engines running 0W20 to 0W16 are very different.

I'll go xW30 or xW40 after this.

Proton:


Generic:

haha, see your luck lo. But, I feel it's less aggressive than using xW20 on the CFE. I haven't look at the visco values, but that should be where I'll start.

maybe later I try xW20 on Exora and see how

CVT cooler leak again - cooler hose crack
VVT leak

100k over, first time I flew over speed hump and landed on the front. Changed absorber after that to handle the way I drive.
Second time, not sure, just started out of nowhere.

If u see the CVT cooler hose, is connected from the cooler and routed under the lower front chassis, and it's almost the lowest point behind the bumper

VVT leak has been for some time, at first I thought was OCH leak, then looked closer and found it
previous service changed the VVT oil seal
now is the VVT itself leaking on the back of the module

Rear cabin droning/booming noise resolved.

https://static.nhtsa.gov/odi/tsbs/2020/MC-10172774-9999.pdf

In my case, the steering rack bushings seem to degrade rather quickly.

I have replaced them during warranty period, and several more after. Reasons I feel the need to change them, is when braking downhill, the steering will 'choose' to pull either left, or right.

Next, I am going to try a set of red bushings from shopee.

Steering rack bush. Happens to me every few months.
Change to PU silicone one now.

Will update.

One more thing, changed spark plugs. The NGK must've been at least 60k km.
Now on Denso. Noticeable less vibration and engine droning noise.

Initially planned to change engine mounting, but now will just live with it first. Current set are TRIM changed at SC 33k km ago.

dua dua pun boleh

if you always run with aircon, can use 5W30 (lower coolant temp)
if always run without aircon, can use 5W40 (higher coolant temp)

See comment for the parts to change, shopee got sell



new engine oil does that to my Exora during cold start, but after a while it will be back to normal
what happen is like this, turn on key, then crank.... it will not start
even if start, sometimes it will die

cycle the key again, it will start up like normal

one of the suspect is the VVT actuator, what I notice sometimes when I open the boot, and turn the key to 'on'
after a few seconds, the VVT intake side will have a 'klak' actuation sound

update: 130k km steering rack right side leaking, turn steering when stationary will have 'kreak' noise

yeah, I heard something similar, IINM it's near the intake manifold, so need to buka the hood to listen

for me, it happens quite often after an oil change, so I'm guessing because thinner oil causing the oil pressure not build up fast enough during cold start, the stock oil is 10W-30 to 15W-40... now I just use 5W-40

nothing wrong with the oil
nothing wrong with the car

just observe and I guess this is probably the pattern of this car, haha
I'm used to it already, and sort of expect it after oil change everytime

that was SleeplessEyes

Iriz is NA. Stock oil is xW-30. So I guess most of us including myself would use the 0W20.

Did you buy a used one? Or brand new?

ok, welcome to the club
suggest change oil 5k instead of 10k, that's all, the rest follow schedule, don't put engine oil additives

Clutch adaptation is another issue, or pattern, with this car

After CVT oil change, it will need a few, when cold, when hot, and then occasionally, during hard driving, the CVT durian logo will show up on the dash. It will on for half a minute, disappear for a few minutes, turn on again, and keep cycling...

When that happens, do another round of adaptation...

happened to me 2 times, both also after CVT oil change...

another CVT durian happens when driving the car off during cold, the CVT stuck at low gear, meaning the RPM will climb up but the car moves slow
don't panic, this one just off engine, restart, do adaptation, should settle

most of the time when stop at traffic light, I will do adaptation minus the reverse gear one

However, if after adaptation, the gear shift still jerking, or when you tekan brake masuk D, the car still vibrating, or when you masuk reverse, the engine lost power and died... could be engine mounting issue

Exora engine mounting, now the Proton give one is "TRIM" brand, chop on the mounting itself. This one last me the longest, so far no vibrate.

Nissan?
