And to add to that, Servo is pathetic. It takes a long time to break in during which your car will feel unsettled. Even after it breaks in, the engine respond will be rather dull. You will start feeling this isn the next few weeks. My refil of the same oil was really black and viscous in just 6000km.
If you went to Sai Service, let me tell you- privately the SA admits that full synthetic is better but also that his company policy is to put in semi-synthetic. Probably, they have got the best deal with Servo because they just refuse to put in anything else. They buy it in bulk drums rather than sealed cans, so there is always the possibility of contamination. These are the same guys who filled 5w30 full synthetic in my Swift just one year bask without me even telling them anything. The situation is so bad in Mumbai, even Maruti authorised retailers do not have 0w20 oil in retail packs, such is the grip of the wholeseller supplying all these people. And, for the price they charge you for that oil, (likely you paid just under 2k for 3.2L) you can get full synthetic MGO Shell.
Since you have already paid, I suggest you drive for a few weeks on that oil. If you are not satidfied with the handling ping us and we will tell you where to buy the MGO synthetic oil in retail
