Are you kidding? The most robust spec oil you could find? You know this isn't some solid lifter 1960s tech Hemi and its a 1.4l Fiat motor in an economy car. People need to stop equating turbo with the high performance and the need for the best oil possible. Turbocharging is in all levels and trim of vehicle lineups now most to bump up efficiency for fleet MPG and don't need boutique oils more most applications.
I suppose this car might be equipped with the naturally aspirated 2.0 or 2.4. Even more reason NOT to spec the most robust oil I could find and just stick to whatever flavor he likes that meets the requirements.
Not sure what difference engine size and manufacturer have to do with it.
But surely a small engine that is turbocharged to allow it to perform like a much larger NA engine is in a higher state of tune?
A 1.0 three cylinder engine producing 125bhp with performance as good as a 1.6 NA an sometimes slightly better than a 1.6NA is going to be harder on the oil than the 1.6NA.
The new fashion for European manufacturers is to downsize engines and then use some form of forced induction. That way you can get fuel economy and emissions down without having to worry about owning a modern Euro 5/6 diesel.
There is talk of some manufacturers abandoning diesel altogether for non commercial vehicles.
Interestingly the 1.0 Ecoboost specs 5w20 oil and I have not heard of any engine failures yet. Though to be honest Ford engines have been pretty robust for years. Unlike BMW and Mercedes who seem to struggle to make camchains last as long as the average Ford Cambelt (many are 150k mile intervals) a make 116i just snapped its camchains at under 60k miles, the vehicle was only 6 years old!
