can use this as manual gear oil?

Anyone here know when should I change the engine oil again? I changed it last time at 192.2k , now the mileage hit 192.5 k .... The mechanic forgt to wrote down the mileage on the sticker.....omg

These info plus lots of other basic info are all listed on the 1st page of this forum.

According to the owner's manual, if the free play exceeds 30mm, better have it checked. If the protective gaiter is broken, grease will leak out and dirt get in, wearing out the teeth faster.

Steering system may be affected by components other than the rack/pinion teeth, like the tie rod rack end, monkhead worn out...

Ok, thanks for the info.... how to refill the power steering oil? My steering gt whining sound... Whats the difference between transmission oil and engine oil???

Transmission fluid for gebox. Thick and lasak

Engine oil for engine. Thin and strong detergent to prevent acidic due to hot working environment

Both can't be exchange use. Gebox oil will jam the engine due to too heavy; engine oil can't cope with transmission kinda heavy friction working environment.

How bout the power steering oil???

to add in, while the specification of SAE for transmission fluid and engine oil is different, the actual viscosity can be the same.
so to say transmission/gear oil is thicker than engine oil is incorrect.

example:
SAE Viscosity Grade (Motor Oil) 5W30
SAE Viscosity Grade (Gear Oil) 75W80

with this, the engine oil is actually thicker than the gear oil!

additionally, detergent is not so much to prevent acidity of the lubricant, more so to be able to clean/neutralize carbon/combustion blow by and keep it in suspension within the oil
there are of course other additives (working along side with detergent) to prevent the oxidization/varnish/acidity of the oil.

As a matter of fact, depending on your driving conditions, transmission can actually be much hotter than your engine oil (remember what i have experienced in my gear oil?) as your engine oil has radiator/coolant to help maintain temperatures, while the gear oil's only way to cool itself is the transmission case which is thick galvanised steel or something (IINM anyways) and those aren't exactly the best materials for heat conductivity

the main reason gear oil cannot be use in an engine is due to the lack of detergent/dispersant additives, while for engine generally it is as you said, as that is made way for detergent/dispersant additives in favor over friction modifiers.

interesting as to how i am answering similar things on both threads

please consider reading the first page of this thread as well as this thread:
https://forum.lowyat.net/topic/3310512

a lot of your questions have been widely available around these forums on various threads (or even google)

Usually, powah steering fluid compatibulu with otomatik oil

Ordinary question, gib ordinary answer. This will make you sound a lot more "friendly"

people who knows me enough will get there eventually

The trouble is, how many of them(us) know you well enough

i would leave it up to fate

I'm also facing the same problem currently. I had my wife drive the car while I sat at the rear passenger seat (LH). She drove on uneven roads and I opened the door poking my head outside the car to listen for the source of the noise. No clue.

Through my observations, I can quite safely conclude on the following regarding the issue:

1. Noise appears when the rear seat is loaded. The bigger the load, the more prone it is for the noise to appear.

2. Noise appears as the ambient temperature is warmer. Hotter day, easier for the noise to appear. Made worse when the rear seats are loaded.

I typically have no issues when driving alone in the car. If I had to make an educated guess, I would have to say it has something to do with the body itself. I inspected the spot welds behind the rear seats and saw that some of them had let go. I'm wondering whether that maybe the cause of it. At one particular time, one of the broken spot welds was the cause of a "squeaking" sound; I spread the joined parts apart and the noise disappeared. Worst of all however, (see attachment), I fear something might be breaking loose even more...


Attached thumbnail(s)

My experience tells me your car was involved in an extremely bad accident before. By the look of it, the C pillar has been compressed and heat treated in order to pull it back out. Looking at the wavy metallic painted surface, suggest that was patching of silicone/fibre putty. Edge of the rear windscreen sealant shows the rear windscreen may be changed/not factory fitted. The crack you shown, may not be a sign of metal fatigue, high chance it was a putty crack in my opinion. I do believe, if it's a metal crack, the fatigue site would have shown enormous of rust trails.

Regardless ayam right or wrong, please do send your car to bodyshop for checking. It is very dangerous if it really is a metal fatigue. Your car could goes disintegrated while you're driving. Endanger your life, your other occupants and other road user's life as well.

i was going to say crack due to metal fatigue, but i guess what you posted made more sense.
thanks for sharing

Been seeing too many dead pipu's car Nowadays I drive at haiwei also kenot exceed 100 liao The other day took me 4 hours from Muar to KL tsk tsk tsk

I try not to think about those when I'm on the road. Although admittedly I do think about it time to time, even sometimes imagining myself crashing

Btw Albert B your England very the powderful geh. Simple, straight forward, easy under stand. Grammar all ngam², unlike Quazacolt all teknikal jargon kamout from him but pipu dunno whats he toking abau If me ar, hailut.org liao. Mai waifu owiz say me, u ar when ask u spik Engrish detaim ar, spik like dunno which pasar kamout lidat. When ask do ploper presentation at official event ar, even worse. The whole sentence like direct use online translator translate out lidat Just a few days ago a porum member quoted me, then directly use Google translator translate my posted England, surprisingly Google translator got the exact Cainis meaning
