Lubricant Discussion- Engine Oil / Gear Oil

Then that is not the issue of using 5W-20 grade. Your engine has worn and producing noises when you switch to recommended grade.
Using thicker grade is only masking the underlying issue.

[Thinking]

there is no smoke, no power loss, ~ 13 kmpl in city and ~ 20 kmpl on motorways with 100% AC. no starting issue no knocking so its not an issue with the engine of any kind AL HAMD U LILLAH.

it gives 13 kmpl even climbing nathiagali AL HAMD U LILLAH.

there is occasional oil reduction which is as per design and written in car manual as a design thing.

car never over heated and works smooth as butter. so no engine issue.

underlying issue is bad quality fuel and we can not go below the recommended oil grade however we can always increase the oil grade range. it might cause reduced milage however oils with higher viscosity grades are always more protective under strain.

[ifadey]

If everything is fine with your vehicle, it should have performed ok with 5W-20 since 0W-20 is the recommended grade.
5W-20 is not a lower grade than 0W-20. In fact, it's slightly thicker for cold starts and same as 0W-20 at operating temperatures. 0W-16 and 0W-10 are thinner grades than 0W-20. You can check product data sheet of these oil grades from any brand as a reference to understand its viscosity.

I understand it's hard for you to accept because you had a bad experience, but that doesn't change the fact. If you talk about experience, I have safely used 5W-20 and 0W-30 where 0W-20 and 5W-30 grades are recommended. No engine noise, no knocking, smooth running engine.

These oils can only be used in brand new vehicles if you are the first owner

Assalamo Alaikum.
Anyone who have used AMSOIL Oil FILTER ? (& for Hondas)..
How was the experience?
And what is the micron rating of the genuine/company Honda Oil Filter?
Thank you.

[saqibhassan95]

Anyone who have used AMSOIL Oil FILTER ?

yes but not in honda

And what is the micron rating of the genuine/company Honda Oil Filter?

companies in Pak don't mention micron ratings, it's hard to find

No dear. the logic of choosing the oil grade is that you can always exceed the recommended range but cannot reduce the range. like in case of 0w-20, you can have 0w-30 but cannot use 5w-20.

better explained here:

Bottom line:

Stick to OEM specs ONLY, in API rating and in Oil Grade.

The only time you should deviate from OEM is when you experience oil consumption / oil level reduction due to age of engine, then get compression test of cylinders and go for thicker oil as needed.

If there is an availability issue and you cannot find OEM specified Oil then only deviation allowed is: you can go lower on Cold Number (number before W), or you can go higher on Hot Number (Number after W), but you cannot do the opposite,

Meaning: you should not go higher on cold number (thicker oil during cold start will not move enough and will not protect sufficiently), and you should not go lower on Hot Number (thinner oil will cause oil consumption/reduction due to seal seepage or burnoff).

Hello guys
in would like to know which oil is used in Pakistani tractors for hydraulic.....Usually it is referred as pichlay hissa ka oil ..i have tractor fiat ghazi it uses 8 liter oil in front engine compartment and 16 liters in rear part probably as hydraulic oil ..,.....i used to put diesel engine oil in it as welll but now i am told that hydraulic oil is some thing different>kindly mention which brands or specs of oil for the tractor in hydraulic ....specifically make is fiat ...i have seen oil from Millat as welll as alghazi mentioned as hydraulic oil .. Where can i get oil (hydraulic oil ) in lahore

[jatt.zaildar]

Sahi. So how was your experience with it ? and for how long you used ?

[saqibhassan95]

Sahi. So how was your experience with it ?

fine so far

and for how long you used ?

19k kms

Hi everyone!
I need to know that if its fine to switch from zic(x5-20w50) to shell helix 20w-50 or not? Reason for switching is that i can't afford zic after driving every 3k kilometers. My main concern is to know if it will harm engine or not?or its fine to switch the brand that is a bit cheaper and gives more range with same oil grade? Please pin your valuable comments.
Thank you.

@Xulfiqar will likely be able to help.

[pwuser162557941033]

Sure, but why are you using 20W-50 oil, and why are you replacing it every 3,000 kilometers?

20W-50 in general is the same regardless of the brand you buy. You are effectively pouring sludge straight out of the container if it's a modern engine. And why stop at 20W-50? Why not just pour SAE 50 engine oil instead?

That said, the ZIC X5 20W-50 is a synthetic oil, while Shell Helix HX3 20W-50 is not. The ZIC is a better choice, but if you're changing at 3,000km, you're wasting your money unless you have an absolutely ancient car that specifies that in the owner's manual.

Pichlay hissay ka aail means differential oil, also known as gear oil,

Hydraulic oil is not gear oil, its not used in the differential either, you can buy it from any oil store in litre pack and drum pack,

Its sold by iso number which is the viscosity of it. Check the label on the pump or the owner book for what viscosity you require.

Hi guys can anyone advise where I can find rear differential oil/fluid for Toyota Hilux Revo in Lahore and which type/brand to use.

Not to create another post if someone can also advise if the front diff fluid should also be changed and what is transfer case fluid.

Any recommendations will be appreciated.

Many thanks

[pakwheels_user]

When I bought the car, its previous owner had a maintenance record of oil changes, where the oil was changed every 3000 km, using ZIC 20-50 oil.
Currently engine health is good as it has no smoke and no oil reduction. ODO reading is 177k. I need advice of some other option other than ZIC that is a bit cheap and has more range.
engine : D16W9 petrol

[sars3331]

thank you sir this is what Millat tractor advises for their tractor ...similarly fiat ghazi tractor advertises similar oil which is hard to find thats why i saw looking for alternative ......as u mentioned gear oil and hydraulic oil are two different things but some how they are using same oil .

It's better to have a maintenance history than none at all, but 3,000km is a really short oil change interval, and 20W-50 is too thick an oil, especially for your engine. I believe the manufacturer specifies 3.6 liters of 5W-30.

I'd suggest using a quality 5W-30, 10W-30, 5W-40, or 10W-40 and extending your oil change interval to 5,000km. You should even be good to go up to 8,000km with a full synthetic oil. Just buy whatever is cheapest at a reputable oil change place. Shell, Caltex, Total, Mobil, SK ZIC, whatever.

As long as you keep an eye on oil consumption and change the oil and filter on time, your car will be fine.

Let's say your annual mileage is 24,000km. That's 4-5 oil changes using a conventional oil and changing after 5,000km, vs. 3 oil changes using a full synthetic and changing after 8,000km. Do the math, find a quality oil and filter that costs you the least, and forget about it.

In my case, I use 3 liters of full synthetic Havoline ProDS 5W-40 API SP in my Suzuki F6A. It cost me Rs. 2,120/liter a month ago, and the filter cost me Rs. 1,800. My annual mileage means I only change my oil twice a year, so that's a cost of Rs. 16,360 per year.

If I find an oil from a reputable manufacturer that lowers my operating costs, I'm going for that one.
