Mineral or Synthetic Oil?

[Viru]

Dear Viru, not all Swift diesel engines can use 10W-40. Don't you know it?

I hope you can back that up, because as far as I can tell, the conditions for this engine are as follows:

Regular use
Moderate driving style
Indian Climate
Compression Ignition

10W40 seems ideal, 5W40 would also be suitable, but none of the 5W40 oils I have come across have commendable additives, which is why I recommended the Magnatec 10W40.

Yes Viru we must consider those following conditions. In addition to that you must also consider the whole engine too. No two different engines need to be used same grade of oil by just considering only those things.

Two years back Maruti said swift D costumers starting from some particular VIN should use 5W instead of 15w, So according to me its wrong to use 10W instead of 5w if it belongs to that VIN. Remember there will be some obvious reasons for recommending lower cold viscous oil isn't it?


If his VIN number doesn't includes in it, then as you suggested 10W-40 can be used instead of the recommended 15w-40 grade oil, because lowering cold viscous oil from 15w to 10W or 5W to 0W is not going to warm the engine.

I dont have experience with Castrol other than mobil1, but still I think you cant speak too much about additives, because all almost all engine oil brands are using additives in their oils.

Yes, but there are no extenuating circumstances surrounding the Swift Diesel engine that I have heard of till date that would cause me to recommend otherwise.

The difference between 5W and 10W is quite minor btw.

Of course they are using additives, but the nature of the additives being used is what varies, and I found Castrol Edge and Magnatec, along with a few Shell oils to have the best ones.

Happy Holi btw!

YES, I understood that you didn't know about it and that is the reason why I'm here.
Ask your friends who own swift diesel cars or MASS or do you want me to get any proof?

How you can you say its quite minor? In one of the thread where I said I use 0w instead of the recommended 5w you said it will cause damage to the engine.
Viru, probability of Cold start damage occurs where we use higher cold viscous oil than the manufacturer recommended cold viscous value. ie, Using 10w instead of 5w is gonna harm the engine where as 0w instead of 5W is not going to make any harm.

Thanks for sharing your experience. Have you used new MOBIL1 engine oils? If you are a person who like to experiment then I request you to have a try. I know its my mistake to keep sticking into MOBIL1 instead of trying the oils that you have mentioned. But the problem is I'm really addicted to Mobil1 :D

Thank you :)..
Have a fantastic and colorful holi bro, convey my regards to your family :)

My only friend who has a Swift Diesel doesn't even know what 'engine oil viscosity rating' is I will have to take out time to ask a MASS sometime in the near future.

It is minor, but 5W is the bare minimum for our climate. Anyways, I was more concerned about the hot viscosity of 20.
You got that reversed as well, but this is a discussion for another thread.

I only used Mobil1 twice in my old car, didn't find it too great. Anyways they have a rather woeful selection of oils in India.

I only like Castrol and Shell!

Hehe.. me too have few friends who lies in the same category.,
So it means there is no source of information for you about the swift diesel other than from the MASS isn't it..

No man, I didn't use 0w-20 I was talking about M1 0w-40. For this you said

0W is way too low for indian conditions, might damage your engine before it warms up to operating temp and gets the 40 viscosity!

First time I got to meet a person who dont find M1 as great. So I feel interested in knowing more.
1)You said 2 times you used M1 in your old car. Do you remember which grade it was?
2)Which brand and which grade oil you found to be good in that old car? Is that similar to the M1 grade that you have already used? What makes you feel castrol/shell is way too great when comparing to Mobil1 in that old car.
I hope My questions are clear. thanks in advance.

Attaching the pic of Mobil1 5w-30 tech details. This is the one I'm using in my car right now.
Is it possible for you to find the tech details of Castrol/shell? I failed to find any. Just want to make comparison to learn more about them.

I have a few trusted mechs and engineers who I can discuss with, given I get the chance during the day.

You were adamant that 0W20 was the best, and never said anything about 0W40!

0W is too low for Indian conditions, and is bad. But not as bad as 20 hot viscous.

Car was a 2007 Nissan X-Trail 2.0 l, so it's not that old.

For two oil changes tried Mobil 10W40, felt the same if not worse as regular cheaper Nissan oil, which was Shell 10W40
Then tried Castrol GTX 10W40, minor improvement.
Then tried Castrol Magnatec 10W40, noticeable improvement over the GTX, huge improvement over the Mobil.

Suggest me 1-2 options of good Synthetic Engine oils for Diesel Grand i10.
I am looking for True VFM.

Unfortunately though grand is 1100cc it demands 5.3 liters of engine oil (same as i20 4 cyclinder)
So its costly affair

A Grand i10 has to be under warranty period as on date; suggest dont change the OEM oil grade at least till the time the warranty gets over.

This definately makes sense.

In my personal opinion (not to hurt anyone):
Also, not sure why need to spend extra time, money and effort searching for engine oils and pouring them into the engines when the dealers themselves are well equipped for that of recommended by OEM. Not sure what we are trying to achieve here. Don't engine life prolongs or doesn't it be clean if we use OEM recommended oils? Do we have data to back that outside oils prolong engine life as compared to OEM recommended oils? Aren't OEM oils are branded?
Previously I had this experience and finally decided to stick to dealer as it is much safer also in many aspects especially if something goes wrong in the engine. It also removes my headache to waste my fuel going to shops that sells the oil, purchasing them with extra money, and asking the dealer to change which the dealers are relunctant about. What is the outside oils are spurious by chance?

I have a few trusted mechs and engineers who I can discuss with, given I get the chance during the day.

But still you are not aware about 5W-40 thats what I said.
Viru, Instead of being confused why cant you make sure is it true or not.

IMO its better if you could find few more trusted mechs for the better updates ;)

You were adamant that 0W20 was the best, and never said anything about 0W40!

0W is too low for Indian conditions, and is bad. But not as bad as 20 hot viscous.

Viru, thats wrong man, no where I said 0W-20 is the best because I dont have experience with 0W-20. Please don't try to script. I'm only responsible for what I said. Things I said about 0W-20 is the details I got from different MASS and also from MARUTI SUZUKI via emails and calls. I have even provided the contact details of them. So I request you to blame me only after contacting them.
Thats a big lie. In my previous post what I have quoted is YOUR OWN WORDS blaming on 0W-40, then how can you say you did't say anything about 0W-40? I request you to click on to the quote to get into your post saying about 0W-40.
We human beings use to forget what we said. Seriously no offense bro.

Today Had a visit to POPULAR service center(MASS) to replace the door handle. When I asked about 0w-20 they said newer kseries wagonr are using 0w-20.

Anyways my doubts with you is not about 0W-20. Its about the way you talked about 0w,5w and 5w,10w.
You said 0w is bad for engine when I said I use Mobil1 0w-40 instead of 5w-30
But here you are saying "The difference between 5W and 10W is quite minor"

So What I'm saying is

probability of Cold start damage occurs where we use higher cold viscous oil than the manufacturer recommended cold viscous value. ie, Using 10w instead of 5w is gonna harm the engine where as 0w instead of 5W is not going to make any harm.

Viru, can't you agree with this???

Car was a 2007 Nissan X-Trail 2.0 l, so it's not that old.

For two oil changes tried Mobil 10W40, felt the same if not worse as regular cheaper Nissan oil, which was Shell 10W40
Then tried Castrol GTX 10W40, minor improvement.
Then tried Castrol Magnatec 10W40, noticeable improvement over the GTX, huge improvement over the Mobil.

First of all, thats a very good car. :)
I think what you have used is not the brand CALLED MOBIL1. Most probably it is MOBIL or MOBIL SUPER. I dont know whats the difference between them, but what I could know from Mobil1 staffs is they are different and Mobil1 is far far superior to them.
The reason for saying is I dont think Mobil1 had 10W-40 FULLY SYNTHETIC engine oil in India in those times.

I request you to collect the reviews about the the new Mobil1 5w-30 esp from the people who are using it and if you are ready to spend few more bucks on your engine oil, then have a try with it.

Hi Srinivas,

Here the reason is not because OEM oils are bad.

OEM oils are not going to harm unless you dont abuse your engine or you change the oil regularly. Yes in this case OEM oils are good.

Now let me say how outside oils get more value.
1)OEM can perform well only for the above stated conditions. So a person who likes to drive at higher rpms will prefer better oil than the OEM.
Because OEM oils will soon looses their lubrication ability with ones driving styles(RPM range). So we will require frequent oil changes.

2)Engine smoothness: If your search ends with the right engine oil, then you can definitely feel its smoothness.

3)Better flow of oil will result in better performances.

OEM oils are not mend to be an all rounder there by it cuts down its price and makes the regular service cheaper which helps in attracting the customers.

In addition to engine oils, OEM spark plug, OEM intake filter, OEM tyres, OEM Headlamps etc are all made for the normal usage. So what I'm saying is we cant except an average cars OEM products to have a wonderful performances

While I trust in manufacturer recommendations & stick by it I don't have any trust in advises provided by service center folks (including service manager). Very difficult to find a sensible and knowledgeable guy these days. That is why it is best to adhere to what is specified by manufacturer with respect to service as well - interval of service, recommendations on replacements etc and not seek advise of service advisors unless really required.

I will quote an example with respect to my Ertiga ZDI.

In 10k service, I noticed that wind shield washer liquid was added in bill and was told it is good for windshield to avoid scratching and also keeping the glass clean. But what I figured out a day later was that visibility going down when used it.

I had to eventually go back to service station since they used hard water for water wash which left marks all over the car and inside too (guess they left a window down). Upon further investigation & long argument, service manager agreed that they use the same hard water for windshield too which was causing smudged windshield in spite of being mixed with windshield liquid.

There were some more concerns like replacement of AC filter which was only 5K kms old. Service manager claimed it was replaced since the filter was dirty. But upon inspection the filter was found to be as good as new. He apologized then and agreed to credit this amount in next service.

I could go on and on, about why we shouldn't blindly go by service center. But if I have to summarize, all they look for is ways to inflate the bill amount by providing so called 'value added services' (vehicles are built rugged these days & hence service / replacement needs have come down drastically when compared to 90s).

OEM by Hyundai is not synthetic oil its mineral.
I asked service adviser do you have a manufacturer recommended synthetic oil?
answer is no.
Universal truth is synthetic oil is better than mineral ones

Am a bit late here guys,but i just need a quick answer,
I have misplaced the manual & bills for my Swift Petrol 1.3(G13BB) but am sure it uses 15w -40 & i feel at last service 05w-30 was added instead & that made me run low on engine oil at 8000km after service(had to top up).
Planning to send car to an authorized garage so i can overlook everything.
Planning to get Shell HX 7 (semi syn) & see the results as car has done last 74000 on only mineral oil from company.

Just to clear things if recommend is 15w40 & i use a 10w40,the 10w should give better cold start protection while providing same viscosity or protection at higher temp as the other ?

As far i understand the new k series petrol use 05w30 which mean less thick but older engines like the esteem & my Swift petrol 1.3 need w40 atleast for protection.

Waiting for advice to clear the confusion.
