Hello All,

I recently took possession of my Dad’s Baleno 2019 - Petrol variant. Upon noticing a difference in vehicle performance and mileage I started looking into service history.

In the last PMS, done in April 2022, the service center in Haryana used 5W40 synthetic engine oil instead of 0W20 synthetic.

The car is now in TN and have been used for about 2500 KM till now, after the service.

I have sent a mail to Haryana and TN regional office and also to Nexa asking them to look into this issue and change the oil to the correct one.

But haven’t heard back from any of them. Any suggestions on how to proceed with this?

Regards,

Drain the oil and get the correct grade put in. Why keep running the car on wrong grade till Nexa and you sort out the issue.

1. Change the engine oil at a MASS/Dealer and apprise the same in your mail chain. This is a deviation from standard practice and should be corrected by them.

2. A FNG had put 5W30 in our wagonR instead of the recommended 0W20 and honestly I couldn't feel a difference maybe it was too slight to be noticeable but I do suspect that the 0W20 had slightly better FE. I ran the car for 5000kms and reverted back to 0W20. Again no significant change except slightly better FE.

5W means a thicker oil when cold and 40 is a thicker oil when hot. The 40 should be better for hot climates but the 5W could be an issue.

But the manufacturer knows best(especially in warranty) and you should have this mentioned in your owner's manual.

Here's an excerpt from the Suzuki Access125's owner's manual, just for learning purposes.
Based on this, for my climate, I should be running a 10W40 instead of the 10W30 which is widely used.
I use 5W40 and the results are excellent for performance, smoothness and FE(3-5 kmpl increase).

Quite an act of omission by the concerned ASC. Please keep on sending reminders to the concerned at Haryana, TN Regional Office and Nexa. Hopefully, MSIL will have a general customer helpline and customer feedback forum (apart from Nexa) where you can also agitate the issue, citing your first grievance that has not yet been attended to.

MSIL/Nexa/ TN Regional Office needs to also be asked for a full engine check-up and rectification of shortcomings if any, due to the improper grade of oil used by them . This needs to be done free of charge.

The 5W-20W used by the ASC would be a bit more viscous at its lower end (for cooler climes) while 20 W its higher viscosity limit is again suited to cooler climes as compared to 0W-40W and moreover you have paid a premium for the synthetic oil. The hotter the climate, the higher the viscosity required and hence 20W would have been unsuitable in a place like Chennai.

Thanks, I noticed your post and realised that I had made a typo in my post where I said 5W as thinner instead of thicker as compared to 0W.

Although MSIL mention the oil grade in their bill and charge for the same since it would be a different item code. I am guessing that's how the OP got to know.
5W40 which they poured in would've been fully synthetic too. 0W20 MGO by Ecstar costs around 1200 for 3 liters IIRC.

Thanks for the reply.

As I will not be using my car much until 5th of September, I will keep pestering them until they respond. Or as a last resort will have to think about changing it myself because I will have to start using the car from 6th.

Hoping that things will work out. Fingers crossed.

Yeah. I don't mind paying a bit higher for the right good stuff but this is plain nonsense from the MSIL side.

Have attached part of the bill below.

It's a mess up on their end, I find MGO prices to be equal or lower than market and you get billed for the exact amount so turn out to be more economical.

Get your stuff sorted and try to stay away from that ASC going forward.

Does Nexa has any vehicles that use this “wrong oil” else how will it come at your stores? Can be either an advisory or a wrong description if there’s no other Nexa car that uses mentioned type.

Also, usually Dealerships get large barrels so and service technicians withdraw oil themselves and not get individual cans issued that someone in store can mess up.

I also doubt if someone can notice difference in engine due to change in type of oil, has to be physiological

If your car is a bs4 by some miracle for a 2019 car feel free to use 5w30

If you are on a bs6 car the 5w30 oil is not rated for your engine so drain and change asap. 2500 km won’t hurt the engine but more usage will, in the longer term

There is no need to especially go and change the oil.
If Mass is not replacing the oil for free, let it run till the next change interval.
Apart from slightly lower mileage of 2 to 3% (not km/l) nothing is wrong with this oil.
You already did 4 months/2500 kms with this oil.

It is not a question of mileage or not. Older spec oils such as the a5b5 5w30 are not rated for bs6 cars.

Maruti has reduced viscosity of recommended oil over the years due to tighter tolerances, coated piston and cylinder walls and of course, higher FE. From 20W40 in the Altos, 5W30, 0W20 and now 0w16. Hence this seems to be difficult for the service center to stock and such incidents happen. And 5W40 is the synthetic grade they usually try to fleece customers with since this costs higher than 0W20 even though that is also fully synthetic.

Issue with using thicker oil in these engines was once highlighted by LeoShashi. Such cars had piston ring failures because due to the fighter tolerances, thicker oil would mess up the rings. So it's better to revert to the recommended grade immediately. If the use of 5W40 has been mentioned in the previous service bill, then it's at least good evidence in case of any issues but beyond that going back to the dealer in a different city would be a hassle.

I tried to procure 0w16 for my Spresso in January this year and all the service centers i contacted in North Bangalore including Nexa workshops didn't stock it. I had to procure it myself by traveling 50 km to and fro from Hebbal to Essar automobiles authorised spare parts stockist in Uttarahalli!

All the authorised workshops around here were assuring me that 0w16 was an inferior oil and i was better off with the fully synthetic grade 5w40 that they had.

Not necessarily. Have purchased Gulf Ultrasynth 5w30 and it is FS and compatible with BS6 vehicles as well.

Again, the connection between emission norms and oil spec has little to do with damage per se to the engine versus perhaps more emissions and non compliance to BS6, IMO.

If it has an acea c2 or higher rating then you can certainly use it in bs6

This one seems to be api sn and ilsac gf5, an American spec more or less equivalent to a5b5 so not really the right choice for bs6 unless it’s some other oil from this brand you bought
