Suneel bhai yeh bataein keh gaari ki diggi main engine kaisay fit aa gaya.
Anyways other than that I don't have any issues with the turbo variant. It is the fuel and fuel alone. No issues ever since I've used the Total HOBC.
Also driving a turbo car requires more attention for care of the engine.
My cousin himself has a blown engine of the 1.5 Turbo and if I would have heard this story from someone else then maybe not believed it however I know for a fact that he pushed the car way way too much, on the wrong fuel from the wrong pump and that too as soon as it starts. When my car was knocking in the first month, as soon as I had the first 2-3 knocks, my foot was off the gas. Kuch to ignore kartay hain and that is an engine death wish to push it further when its knocking. There are ways to handle this car's engine, it can't take the massive beating of the R18 which we've seen in the past. Woh to Irani fuel pe bhe chalti Hai without any instantaneous damage to the piston heads.
Hence I'm sure a lot of people don't care about their engines, don't know the first thing about maintenance. I know many people who say keh "oil Kya change karana, jab gaari kharaab ho gi to dekhi jaye gi".
