Didn't ps fix this issue? There should be a sticker on the firewall that should state 0w20 rather than 10w40 like the earlier models in 19 and 20 had. I mean, if you take your car to them, they will automatically use 0w20 now. The same is for the gear oil. I believe they were using 80w90 or something like that despite the fact that recommended was 75w.
You need to double check the alto forums. I remember I switched to the recommended oils and the car felt lighter and quieter under operating conditions
