Suzuki Swift 2020 Oil Viscosity Recommendation

[anon35615524]

Then you have got the answer to your question / query!

I have already mentioned in my posts above, the reasons for any / all of this.

If they haven't replied categorically and clearly, it means that they themselves are not clear about all this.

Since WagonR came into production in 2014 the back side of the last page recomended 0W20 in wagonr but suzuki never accepted it.

Even caltex wala looked at me, why do you put such expensive oil in this car. 0W20 is usually for hybrid cars.

Any ways since suzuki started their own 0W20 in 2018/2019 now every car should have 0W20.

Still suzuki Altos owners manual doesn't recommend 0W20 anywhere i dont know why.

[qasimahmedmisc]

Sir that is the issue. Suzuki said that I can use 0W-20 without any issues. The guy selling TOTACHI says that he's put 0W-20 in many Swifts without issues. Other people suggest that 5W-30 is the least I can go.

The owners manual also says that 0W-20 can be used but people say that is for Japan not Pakistan and i fail to understand the logic of outside temperature when engine is at operating temperature already. Kindly see the picture of owner manual I have attached below

I had been using SGO 10w40 ( mineral i think) from day one in my swift till about 30k kms, switched to 5w30 SGO which is a semi synth(dealership guys weren’t in the favour lekin somehow karliya maine). The car has been running fine and now the odo is on 33k due for another oil change because it’s been a little more than 3 months. I decided to order liquimoly molygen 5w30 even though many people were against it as its not the best value for money(which it isn’t btw). I read positive reviews on amazon and went for it cus i wanted to test it myself , there was a problem and i got 5w30 special tec AA instead which i’ll be pouring on monday. 10w40 mineral didn’t give me any problems , car used to run smooth and gave me around 14 avg with a heavy foot occasionally on AC. I calculated the avg on SGO 5w30 and the car is giving around 11 with approx 1 hour idle with AC. I didn’t feel a difference in the pick also , or maybe it’s too soon to comment as i’ve just driven in 3k on the new grade. Nevertheless i’ll pour liquimoly 5w30 next week with engine flush and share my review. Till now i don’t think my car is performing good on 5w30, 10w40 shouldn’t have but felt better don’t know why.
In my opinion i think 10w40 or 5w40 both are good for this engine , i’m not so sure about 5w30 as of yet as i’ve encountered no one pouring this grade. Your car is new i would suggest to use 5w30 from now on and quit SGO as it’s not the best available, choose a better brand , ive heard many positive reviews about total quartz 9000 5w30 you may try that but i won’t suggest using 0w20 grade. 5w30 is the least you should go and keep using it till eventually the engine dies.

Thanks for the detailed response. I still have about 2000 kms until the next oil change that's why i want to research to my fullest before changing oil grade.

Also please see the picture of owners manual. It does recommend 0W-20

[itzahmd]

Thanks

Anytime.

I also researched a lot and came to the conclusion that 5w30 best suits our climate and conditions. I went through a forum of owners of jimny with the same engine , most of them were using 10w30,5w30. Various other forums also suggest 5w30 for this engine. Liquimolys website also recommends 5w30, i emailed them infact and their reply was simply to pour 5w30 and forget. You can pour 0w20 , it won’t do any harm to the engine too if the cooling system is working fine. As basit bhai mentioned above about a video in which two cars were tested , one using a slightly thicker viscosity was a bit cooler.

@dms664 they are coming up with a new sedan to compete in 1300 cc segment with Korean & others

I also researched a lot and came to the conclusion that 5w30 best suits our climate and conditions

My conclusion too
That's why I recommended same

[qasimahmedmisc]

The main reason I want to shift to a lower viscosity is that I want better fuel average and above all better acceleration/Pick up.
I have an automatic and I understand that the pick isn't going to be on par with the manual variant but a 1300CC hatchback car getting defeated by a 1300CC GLI automatic is embarrassing

[itzahmd]

hahah yaar out of all cars , getting defeated by a gli auto is embarrassing. You should get the car tuned from the right mechanic if it’s feeling sluggish.Mine is too issi liye i’ve decided to quit dealership and get the car maintained from elsewhere.

[dms664]

Why ditched ciaz then?

[qasimahmedmisc]

Yar car is brand new so i don't think tuning ka issue hoga. I have reached alot of websites and FB pages that do performance tuning on other cars but they don't tune swift. I don't know why

[itzahmd]

same scene, i asked unichip , they tune gli but not swift what’s up ?

[itzahmd]

without ac mines okay but with ac it feels like a mehran

[qasimahmedmisc]

Probably because swift has different ECU protocol. Issi waja se you can't use OBD scanners on swift. Only suzuki dealers have the computer for it

[chinyoti]

I still don't understand viscosities. I believe the newer the engine the lower the viscosity.

A oil vendor told me most oils are of same viscosity at engine operating temperature.

Toyota was putting 20W50 in my friends brand new petrol Fortuner. So these idiots will put in anything

[qasimahmedmisc]

Yes I know. I have the 2017 4x4 Fortuner myself luckily I did follow the owners manual and used correct grade. recently shifted to 10W-30 after 85K kms

[ch.talal]

Well at high temperature of 80+ all engine oils act similar regardless of their viscosity. But the actual issue arises when engine is cold especially in winter season. So considering that always use recommended viscosity oil.

Suzuki is going with 10w 40 because they buy it in bulk at very cheaper price. In fact they get that in large drums and pour that in new cars inside their Karachi factory. Thus cut the manufacturing cost. They also sell same cheap oil after packing in bottles and charge premium price for that.

[anon35615524]

If you see in the pic., 5w-30 seems a very reasonable choice.

At the end, they have mentioned about 0w-20, but there is nothing new in it.

Of course it'll give good fuel efficiency and cold start up, but at the same time, it also needs to be checked that whether this oil grade also suits a particular engine or not?

Try putting in 0w-20 in 70s or 80s Corolla engine. It will also definitely provide good fuel efficiency and cold start up, but at the cost of increased wear, and decreased engine life.
