Maruti Circular on Swift Engine Oil : Change from 15W40 to 5W40

You have a good point. MSIL used to or still makes Fiat engines under license from FIAL. This could be something that has been driven by Fiat as a condition to supplying a large # of engines to MSIL.

Yes, Fiat already uses or at least strongly recommends synthetic. They use Selenia 5W-40.

Here's an interesting thread for Fiat India car owners -

Sorry guys - this link is being masked for some reason.it is teamfiat dot co dot in pre-service-query/822-engine-oil-change-interval-4.html

Mods - is this default behaviour or is it related to this particular Fiat related site?

I think they may have made modifications to the engine or its state of tune in 2012 that necessitated the shift to synthetic.

Let me put it this way:

Maruti licensed the 1.3L Multijet engine from Fiat and used it for its cars that include Swift, DZire, SX4 amongst others. Maruti manufactured these engines under license at its own facility in Manesar. The demand v/s supply from this factory wasn't adequate and resulted in long waiting periods for their diesel range of cars. Maruti therefore roped in Fiat powertrain pvt. ltd. to manufacture the 1.3L Multijet engines for them to meet demands while it expands its engine production capacity in parallel. This could be a stop gap arrangement and Maruti would eventually insource engine manufacturing when it is able to meet demand.

Now, coming back to the point of engine oil specifications, engines manufactured by Maruti Suzuki Powertrain (or whatever it is called), specified mineral oil for replacement and that is how it has been with my Swift. At the same time, engines manufactured by Fiat Powertrain specify synthetic oil for replacement. As a Japanese company that heavily implements strict processes that seldom deviate from standard I believe they wanted to eliminate any confusion or customization for different sets of engines. Imagine the failure points at service station level if the service advisors were given the task of identifying the engine oil specification based on VIN plates. To avoid this they standardized the specification. This is just my belief and I could be wrong.

Then he told me about a circular which Maruti service center received from Maruti. I argued with him that it is just a sales tactic of service engineer. But today he sent me the circular as PDF and I was shocked to see the details mentioned. MSL is enforcing the service centers to change from 15W40 grade to 5W40. 5W40 is the one which is used in cars like POLO, which will incur a cost of Rs.4400 for 4ltrs. This will drastically increase maintenance cost of swift diesel, otherwise known for its low running cost. Moreover the circular says that service interval is 10,000 kms unlike other cars using the same grade having 15000kms.



Please find the content of the circular and PDF attached below,

MODIFICATION IN PERIODICITY AND GRADE: 1ST replacement of engine oil
Engine oil grade used earlier in New Swift-D(AZI-413D) was 15W40 which has now been
changed to 5W40 starting from chassis no MA3FHEB1S00179480
Engine oil change which was part of 1st free service at 1,000 kms is not required for
New Swift-D(AZI-413D) vehicles starting from chassis no MA3FHEB1S00179480
If, few New Swift-D vehicles before the above mentioned cutoff VIN No report to workshop
for first free service, replacement of Engine oil should be done at 1000kms(1st free service).

Circular PDF: Attachment 958487

Thanks buddy for your information, i have a query, my SX4 Celebration edition manufactured in March 2012, has VIN MA3FFB1S00210563.

I purchased this car in July 2012, i am really confused shall is this with Mineral Oil or Synthetic oil. The dealer is insisting that it is synthetic oil and oil change will be done at 10,000 kms. I am not sure, this is true or not as the owners booklets say replace oil at 1,000 kms

Would appreciate inputs

5W50 will be a synthetic, while 20W50 can be a mineral or at most semi-synth. The cost difference will be 3x minimum.So naturally the former is far more pervasive. With more and more cars having hydraulic tappets I can see the trend to switch towards thinner (when cold) oils. Modern engines are quite happy with SAE40 (or even SAE30) so maybe there is no need to go for a SAE50 limit.

From the information you have provided I assume you are having a petrol SX4. The circular I have shared does not insist on using synthetic engine oil for petrol engines.
You can run your car on any superior quality material, for example using a formula one Tyre will not harm your car any way but will increase the ride quality. So its you who need to decide what is appropriate for you car after referring to the standard recommendations from the manufacturer.

I know many people who run their car on synthetic engine oils and iridium spark plugs even though their cars manufacturer does not recommend that
or their vehicles are not used in extreme conditions. They use it just because of some recommendations or by referring to some enthusiast who use it for some specific purpose.

I would say you can adhere to the recommendations from the manufacturer unless you feel like you are stretching the performance of the car. If your owners booklets say replace oil with mineral oil at 10K Kms then go with that.

Hi Buddy,

Its a Diesel model not petrol. So i am really not sure... whether the manufactured has put mineral oil or synthetic oil. In case its a mineral oil, i don't want to swtich to synthetic too soon.

Amit,

Even I too don't recommend changing to synthetic if your vehicle came filled with Mineral Oil from the company.

That is the problem buddy, i am not sure it came with Synthetic or mineral oil.

If its mineral, then i need to change that with Mineral oil at 1,000 oil.

Exactly my point. This is the only reason I see why Maruti has changed the oil recommendations.

Mine is a March 2012 swift and the manual clearly says first oil change at 10k and service intervals of 10000k thereafter. The recommended oil is 5W4, and I don't think I have an option to change it to mineral one.
