Suzuki Swift 2020 Oil Viscosity Recommendation

[Obxe]

Never got to calculate mileage though.

[saqibhassan95]

5W-30 is better compared to 10W-40

5w will provide better protection on cold starts as compared to 10w
And 5w oils available in market are fully synthetic, somehow better protection and bit longer intervals

[chinyoti]

10W30
5W30
5W40

All are good.
10W40 might be used at little later age of the car. I am using caltex 5W40 in my 2011 Corolla drive. 160,000

caltex 5W40 in my 2011

How is this oil performance in corolla

[htb456]

using thick oil in the "later stages" of the engine life can prove more detrimental. Just jeep using the thinnest viscosity recommended by the owner`s manual.

[htb456]

You can start with 0w20 but for the peace of mind, use 5w30 till engine life is over. Just change oil and filters in time. Dont use 5w40 or any oil that is 10W something.

Let me return to home and I will share a picture of the owners manual here.

To continue further, I saw a video in which 10w-40 and 20w-50 were deployed in an engine under same conditions, and 20w-50 was running cooler than 10w-40 (i.e. engine temperature on 20w-50 was less, when compared to the same on 10w-40). Difference was marginal, but still less.

If an engine does not reduce oil by using 0W-20 but can thin oil still cause damage?

If 0w-20 is not recommended by the OEM, then, it must never be used in any case.

However, if 0w-20 is recommended by the OEM and is the sole, only engine oil to be used; engine is brand new, then this can safely be used, however, if there are many thousand Kms on the Odo, engine / vehicle is old, and it is not the only engine oil grade to be used (engine is based on old tech., and chart is given in the manual, to adjust viscosity as per temperature), then caution must be exercised.

[anon35615524]

A thin oil like 0w-20 may not provide adequate wear resistance in an engine, where it is not recommended. Similarly, in case of old engines, engines based on old tech., etc. where they are running fine on 10w-30 or 10w-40, switching to 0w-20 can bring harm and leakages, so, not recommended.

When engines age, gaps between different moving parts might increase, however small it is (like in microns, etc., but its there). So, if an engine is working fine on a particular engine oil grade, then no need to mess it up. Let it working on it. If problem arises, then switching to further, slightly thick oil can be a temporary solution, but thin oils like 0w-20 is not the solution in any case; at least to me.

IMO, 5w-30, 10w-30 are very safe engine oil grades, to be deployed in most of the recent cars in Pakistan, for all-around-the-year use.

[anon35615524]

I have recently visited Suzuki Mini Motors where they showed me a service bulletin which recommends 0W-20 for PKDM Swift.

I would sincerely suggest to avoid going for 0w-20.

5w-30 and even 10w-30 seem very fine and reasonable engine oil grades to me, for this M13A engine; an old engine based on old tech.

I emailed Suzuki and they also recommend 0W20 and 10W-40 for PKDM Swift

0w-20 and 10w-40 are some extreme level oil grades. How cleverly they have skipped 5w-20, 5w-30, 5w-40 and 10w-30 from these!

[anon35615524]

Did you ask them that why they have skipped these oil grades? And what if these oil grades are to be used?

I would not trust their official email, i.e. email received from Pak Suzuki. They seem slightly ignorant, and lacking technical knowledge.

Need sincere advice on what to do since the engine is new so I can shift to thin oil now.

If warranty issues are not there, then IMO, I would sincerely suggest to switch to:

1. Total Quartz 9000 Future Series 5w-30 (1st preference)
2. Caltex / Havoline 10w-30 (2nd preference)
3. ZIC Fully Synthetic 10w-40 (3rd and last preference)

[anon35615524]

From next oil change, and just stick with it (you may change / switch brands, but try not to switch grades, especially moving from thick to thin)

If I keep using 10W-40 then it would be impossible to shift to 0W-20 later.

Not impossible, but YES, it can be dangerous for the engine, and I won't suggest it.

I hope, all above helps and guides. Thank you.

[anon35615524]

Dear I have already explained in my posts above, and have given my recommendation. You may check.

[anon35615524]

I have personally decided to try TOTACHI oil after alot of research.

IMO, you should prefer to go for "Market k Brands" like Shell, Total, Caltex / Havoline, ZIC, Kixx, Mobil1, etc. Just ensure that oil is 100% authentic.

These not so famous, fancy, expensive, off market brands may be sincerely avoided.

[anon35615524]

I'll try ZIC only if I get it from a reliable source.

You may order online from zicoil.pk , or buy from any reputed shops like Metro, Hyperstar, Carrefour, Makki Oil Store, Pakistan Oil Store in Badami Bagh, etc.

When there is a will, there is a way. Reputed shops are definitely there in all major cities, and some of the details of their official and authorized dealers / distributors are even mentioned on official websites; we just need to figure them out.

[anon35615524]

Dear when difference of temperature between the inside and outside is more, engine oil runs cooler, and thick oils run further cooler compared to thin oils.

For confirmation, you may watch different videos on YouTube.

[anon35615524]

Irrespective its 0w-20 or 20w-50, if I talk about Lahore, Islamabad, or Sibbi, etc., within few seconds on cold start up, both are able to flow inside the engine and lubricate different parts fully.

YES, where freezing temperatures are there, like -10, -20, then 20w-50 must be used after thorough study.

And thick oils, due to highly viscous, remain attached with different moving parts (rings / pistons / crankshaft, etc. being the most crucial ones), so when you start the engine, may be on cold start-up, the oil is already there and attached with them, so less wear and tear due to readily available lubrication.

On thin oils, case can be different.

Thanks Sir for the very detailed response. Highly appreciated!
Warranty is of no use since we all know PakSuzuki will never take claims. I have had 2 issues with the Swift and the dealership response was "Sir Shukar karein sirf itna sa masla hai" so yeah to hell with the so called warranty.

Regarding Oil I got my oil changed at 5K and current ODO is at 7.5K so I've driven 2500 kms on 10W-40. I want to put in a better oil because SGO oils available at 3S are mineral based and I think using Synthetic oil will be better for my engine and will give better fuel average.

Should I drive 1000-1500 kms more before shifting to 5W-30 or should I change immediately?

[anon35615524]

5W-30 (Probably ZiC

As far as I know, ZIC now does not offer 5w-30 any more here.

[anon35615524]

Synthetic oil will be better for my engine and will give better fuel average.

I cannot say anything about fuel efficiency (may be same on different formulations / compositions of oils, like fully synthetic, mineral, etc), but YES, Fully Synthetics are the best!

Then come semi synthetics / synthetic blends, etc., and lastly, pure mineral based.
