Is there any reliable study or data about synthetic oils significantly increasing engine as compared to mineral oils?

Typing this I can only hope that they did check the levels etc. which I believe they would have as even a quarter liter top up would cost a pretty penny + labour would further make it worth their while.
Actually, I missed a point here. M/S recommends mineral oil change in both Swift diesel and petrol at 10k kms. Now, is it same interval for synthetic too. My brother in law (sister's husband) has a swift diesel and he gets service done every 10k kms. We too get our swift petrol serviced every 10k kms, both cars run on mineral oil..I believe 10k kms is less an interval for petrols, should be 15k in case of synthetic. For diesels, yes, 10k is still an appropriate interval even in case of synthetic.

And you are right, Maruti has a GSM server which connects all service data across the country. So, its very easy for any ASC to check the complete service history of the car .

In between, how much have you clocked on the cedia since synthetic oil change? I have done 7k plus and the oil still retains its original colour, though a shade darker. I feel it can easily do 15k kms. But I had to top up 400ml after 7k kms. Something to do with synthetic, that an engine which never consumed oil started doing so after synthetic change . Polo and Civic though have been consistent at same...lolzzz

The recommended interval is 10,000 KM or one year, whichever is earlier. 12 months is the absolute limit, be the oil synthetic or mineral.

Thanks Khoj
I missed out doing the synth change at 10K but will ensure it is done from 15K. Asides the dealer was also a good acquaintance as had got him leads for atleast 5-6 cars from my office for the corporate plan.
By the way I always go the Maruti Service Masters workshop and hope they will have the synth oil.

I am not aware of any study/data on the above but can say with conviction that there is a remarkable difference in the engine performance when you switch over from mineral to synthetic oil. I switched over from regular MGO to Mobil 1 (5W 50) for my Esteem at around 20K kms and my engine is butter smooth.

Hi, I will be giving my car (SX4 AT) for 3rd service next week. In the first service, I was asked to switch to Synthetic oil by my dealer. I did not notice any difference in the engine refinement or performance. How do I ascertain that only synthetic oil was changed? Can I buy the oil myself and get it replaced in my presence? Finally, what brand of oil would you recommend? I see that Shell helix and Mobil 1 are the best choices. Somebody with an SX4, please share your experience, will be really helpful.

The first thing which I did after buying the Mazda Protege was to change its oil and filter.
Put in Mobil 1 synth 10w30 High Mileage with Fram extended guard (10000 miles protection) filter. The mileage then was around 131120 miles. Its now 134xxx miles. I should change oil + filter again next January - as my running is not that high - just office commute.
In winter it takes just a moment more to start up - but sounds smooth and refined once rolling.

My Blue Streak too has about 7K + under its belt since the last service and the oil level is still good all the way around the top mark on the dip stick.

Hi Prasad,

Do share the contact details for the MSM that you visit. The only ones that I am aware of are the two in Delhi and the designated MSM (Thanawalla) in Thane.

I've had the 2nd servicing done at 5000kms for my SX4 ZDi.
Maruti recommends only synthetic oil for this car, which was duly changed during the 1st service.
The service advisor has told me that the oil change will only be done at the next 15k km service.
Is ur AT a diesel ? If yes then ur query is answered.

And yes, they did fill in Mobil 1.

As I remember, the recommended oil change interval for a mineral oil as recommended by Maruti in the manual is 10K kms. It is a normal ploy by most MASSs to say that you need to change oil every 5K kms. While it is a good practice considering the quality of Servo which Maruti uses, recommendation by Maruti as in the manual is 10K for oil change.

For synthetics, typically people say that you can double the oil change interval. So theritically it should be 20K kms, or atleast 15K. If they filled Synth at 1K, you can safely go to 20K service. My personal opinion though.

Having said that, I change mineral at 7.5K with Delvac MX. If I use Synth, I may go to 15K, which I am thinking this time. I am due for 50K service for my swift.

^sri dont you think you change the oil quite late? 5k in dusty conditions as ours should really make the oil cry out loud and engine louder. For my ANHC I get the mineral oil changed every 5k. Engine runs as a dream. Cheers!

With the regular oil yes, I used to feel 5K is the limit, but with Delvac MX I am able to stretch it to 7-8K. I was actually trying to stress upon the attitude of MASS people, that they contradict the writings in the manual and say that this is what Maruti recommends for you. I would feel better if they say, Maruti says X, but because of the driving conditions we feel this is better. And they top it up with conditions like warranty is void if you dont do this !

^ agreed. The A.S.S makes their own rules sometimes. Honda service wanted me to change to synthetic, once I did not budge, he said, Good call; mineral oil is good for the engine. Baffling. Thus it is good to know your engine and adapt to your own comfort rather than the given rule.

Cheers!
