just a little query Dear Raja bro if you dont mind
why new gen vitz engine should have 0w-20 and the slight older engine variant like i have 2013 is fine with 5w-30 ?

[rajaatta]

The new gen 1kr has too much tight clearence of piston to bore distance and slso it utilizes much narrower oil control rings and it's expander is curl type spring which has no clearness at all only 0w20 can penetrate that expanders and the drain hole inside pistons are also too much small. So using any thing above 0w20 will be viscious and doesn't penetrate at those sites and if by any mean it access that area it would not exit that area and due to excessive heat range their unescaped starts to burn their and form heavy sludge their causing the engine oil control rings to fail prematurely.
So toyota is now advising much lower viscosity especially like 0w16 for use in these engines to obtain much superior fuel economy and deposit control prevention. Also THEIR Are Several CLASES Of Engine LUBE With DIFFERENT Flash Points Always Use CATAGORY 3 0w20 Which Is 100%Synthetic Remember 100% Synthetic Had A Price Range Starting From. 7000pkr all oils available below this range are CATAGORY 1&2 ratings with only single certification of API SN only.
Proper 100% synthetic has minimum 3 certifications at least.
Like API SN , ILSAC GF4-5 , ACEA A1/B5 , A5/B5.

Sir, when you are saying new gen 1kr, which year should be considered new gen?

Does this apply to Passo as well?

[Muhammad.Rizwan]

Dear Atta Bahi,

Where you can find AMSOIL And Vololine (01 no.) in RWP and do u have experience with Castrol Magnatec, I have used Castrol, it is good so far.

[abart]

Thanks Dear Sir - so i will keep on using 5w-30 in my 2013 Vitz since it has the older gen of 1kr-fe and according to your explanation 5w-30 is not harmful for older 1krfe engine.

One more question: Is mixing of high octane and normal fuel also harmful for all 1krfe engines? I am talking about local drive not long routes?

[rajaatta]

Yes high octane causes more deposits formation in combustion chamber's in urban driving conditions so it's harmful for urban driving conditions.

[rajaatta]

Yes this applies to the Passo as well the new gen 1kr is fitted from 2014 onwards

[haris.com]

Is this oil any good Liqui moly SPECIAL TEC AA 5W-30?

It fulfills following
API SN Plus + RC
ILSAC GF-5

[rajaatta]

Not good ACEA certification not available for this LM oil it's as good as junk. Just overpriced caltex is better Han this. It has a very bad reputation of flash points

[aunabbas_90]

This oil is overpriced. I am using this one. Although it has improved my fuel Avg but this is not good at cold start i blv. Engine feels heavy. If budget not a problem stick to this Oil...

[abart]

thank you for reply one last thing..what is the current RON values of normal and high octane fuel in Pakistan? And what RON value fuel is recommended for 1kr-fe engine?

[aunabbas_90]

Bro globally
Standard has 87-91 RON
HOBC 95-97 , for pak one better stay proactive.
Recommended RON for vitz 1krfe as per manual of 3rd Gen. 1st facelift late 2014 n abv is 95 RON.

[rajaatta]

Government declared octane values are different from what's sold on fuel stations.
For normal fuel ratings government has declared value of minimum 92 octane but in reality it is not actual 92 to pass the tests they had added numerous additives.
but they proves to be fatal for the new gen engines as they form too much deposits if the octane is genuinely 92 no brownish deposits are found in CC and exausts.
actual 92 Ron has grey ash deposits and CC is as clean as new and no deposits are formed at all plus the engine oil contamination ratio is also low.

[abart]

if recommendation is 95 ron then how can we get that fuel quality without using high octane since it is harmful for our engines as Dear Raja bro shared above?

[abart]

you mean here companies are not selling good fuel, right? here in PK standard fuel is around 90-91 ron and vitz should have around 95 ron fuel so what should we do? isn't usage of standard fuel harmful for engine as well i don't know?

[rajaatta]

No not at all you can use it still but had to do the maintainance job at time.
We'll if you put actual 95 octane fuel which is available in its original form like jdm specs then you would get 25km/L + in 3rd Gen vitz and upto 28km/L in 4gen vitz in urban driving conditions like we have in islamabad.

The low mileage is due to compromised octane ratings.

[rajaatta]

Imagine you are traveling in your brand new yaris all the way from UK to Pakistan through Iran route when you leave the Europe the fuel quality is pathetic still vehicles maintain their pace and keep you running although they don't perform like they were doing back there but still runs you with some compromise on acceleration and fuel economy. They doesn't die on road same is the position here. So use least one and save your engine or keep using the high octane of Pakistan and ruins your engine earlier.

Sir, further guidance needed

o

I have attached image from Passo user manual of the year 2017. It has mentioned both 0w20 and 5w30 oils with API SN/RC, ILSAC GF-5 standards. Should we consider the other standards that you have mentioned as well?
