I don't care what Maruti or Fiat have to say or recommend as I just don't go by their word. I love my car and my engine so I changed the oil (15W40 - used to cost 300/litre In 2011) every 5K kms till 30K kms service post which the interval is 10K kms. The engibe feels great till 8000-8500 kms from oil change post which the NVH from engine goes high and the overall clatter is evident.
It depwnds on the environment conditions in Kolkata. I would recommend use 5W40 for the car.
In mine the oil is by Shell/Castrol with the 5W40 grade. This is the synthetic variant and I change it every 10K kms.
Did a lot of driving around and querying around today.
Driving in the "new" style suggested by you, up-shifting exactly @ 2000 rpm before the turbo kicks in and down-shifting before the engine lugs. No I never ride half clutch for long (something my father taught me to extend life of clutch plate). Even downshift to 1st and keep rolling, if I have to drive at 'walking speed' (say following a cycle rickshaw) for long. Enjoying the bliss. Have learnt how to do it on congested roads of Kolkata too. (Now roads are more congested due to Durga Puja). Tanked up midway today to study any change of mileage. Sudden traffic congestion of Kolkata due to Durga Puja factor has brought down the city mileage from 16 to 13 over the last 3 days.
Spoke to a few oil dealers and MASS engineers.
Oil dealers wanted to sell the highest price oil, suggested Castrol Edge, Motul Xxxxxxx, Mobil Delvac1, etc. etc. for reasons of blah, blah. I understood, they got someone (read: "murga") to sell a Rs 1100/lt oil in a 4 lt package. They did not have stock (naturally - who uses such high priced oil in a low economy city like Kolkata) but will get one if I make an advance. Thanks to all of them for their "help".
Had a looooong discussion with my MASS engineers & came up with a practical solution. (Very similar to yours).
Now my car is running on factory filled 5W40 oil (possibly Castrol - looking at the OEM tie-ups when my car left MS factory). The first oil change @ 10000 kms will be Servo 15W40. MASSs in Kolkata generally does not stock 5W40 for cost reasons, but can get it if required. Now MS recommends oil change every 10K kms for DDIS engines. Practically, MASS recommends 10K interval for 5W40 oils, but a max 6-7K for 15W40 oils, looking at the practical driving conditions and tropical nature of climate in Kolkata.
I also asked why Fiat (the supplier of 1.3L MJD engines) recommends only 5W40 oils and 15K interval for oil change. Firstly, the reason (it seems - to my SA @ MASS) is that the 15K interval is not as per Indian standards, it is as per European standards of road, traffic, pollution & climate. No known to him what Fiat recommends in India for its MJD cars. Secondly, MS has tweaked the Fiat MJD engines before putting them in MS cars. Hence, the 10K interval.
As for the oil grade, even MS recommends 5W40 for these engines like Fiat, but 15W40 works well in Indian conditions in these engines. Hence it is choice #2 for MS. In Europe, 5W40 oil is more readily available as compared to India and price differential is not as big as in India. Again, 5W40 is a must where temperatures are near to freezing point. This condition is more prevalent in European winters than Indian winters. Even in India, cars in Himalayan states should better use 5W40 keeping in mind the winter temperatures. But I am in Kolkata and the car will run in the eastern part of India only (unless otherwise I decide toe take my car to J&K during winter). So 15W40 is fine, but change interval better be reduced to 6-7K kms.
No we cannot get our own oil during 3rd service. Own oil means, customer cannot buy oil of his/her choice from the market and MASS pours it. Reasons are commercial, MS gets to bill it to customers for a service otherwise rendered free. The legal aspect they have put is, if own oil is poured, (even if it is exactly the same as what MASS is selling) it voids warranty (no technical reasons - can be argued at length). Hands tied for MASS (to prevent any "setting" between customer & MASS) also by ensuring that the cost of the oil is billed in the software, and only then the payment for 3rd free service is released to the MASS by MS.
This clause is not there for paid services. For e.g. I get my own oil for my M800 (13 yrs old) for the oil change. MASS writes a comment on the job card, "Oil given by customer". They charge for other labour and consumables like filter, etc. However, this flexibility of getting your own oil is only permitted for engine oils in sealed packs (not permitted for other oils and consumables).
Now the solution: Let the first change be of Servo (that is the tie-up now). The next change will be under paid service, so I can get my own oil.
As per my SA @ MASS, I have got two choices:
#1: Pour Servo 15W40 at ODO=10K and then change oil @ every 6-7K kms interval with 15W40 of my choice. Repeat this process till I keep the car.
#2: Pour Servo 15W40 at ODO=10K and then change oil at ODO=16/17K and pour 5W40 of my choice. Next change oil @ every 10K kms interval with 5W40 of my choice.
I came up with a third, banking on the theory of climatic conditions of Eastern India, non-freezing temperatures, Fiat-Europe vs MS-India, etc. etc.
Keep pouring 15W40 of my choice (except the ODO=10K change) but change interval to be every 5K kms. Now 15W40 oil deterioration at 5K will not be as bad as 5W40 at 10K (agreed by my SA). Price factor: INR 1100 every 5K kms = INR 2200 every 10K Kms with 15W40 oil. VS INR 4000+ every 10K kms for 5W40 oil. Surely a factor for keeping maintenance costs under control.
Also the engine gets "fresh" oil every 5K kms. My SA recommended to go in for Castrol Magnatec 15W40. He says it is semi-synthetic and a very good oil.
Also, this model is good for the current difference of market prices of 5W40 and 15W40. My SA feels that in future, with more and more engines using 5W40, price differential may come down to European levels (narrow down - in short) and then the change model can well be 5W40 every 10K kms without burning a hole in the pocket.
Like I said: the proposed model is very similar to what you have followed. Maybe, in future the relative difference of prices of 15W40 and 5W40 may close in, and I might start using 5W40. Till then I will use 15W40 every 5K kms. Also, good oil to be used in the old engine !!
