Oil for Gen 4 Jimny

Hi there,
I am about to change the oil of my Gen 4 Jimny for the first time, and I am going to do it myself, as I don't like the factory stuff 0w-16, it looks too thin to me. And the factory oil seems to be some eastern Europe crap brand /ECSTAR/. 
Is there any problem if I put the 5w-40 Motul X-Cess 8100 instead? 
The climate here is something like in north Italy.
Thanks!

Ecstar oil is manufactured by Idemitsu which is a Japanese company who supply the other Japanese car manufacturers like Honda and Toyota.  Regarding the oil grade to use I suggest you follow the recommendations given in the owners handbook.  If you don't have one it can be downloaded from the Suzuki cars web site.

Ecstar is just Suzuki's own brand for fluids, as Mazda has Supra.

0W16 is selected for marginally better fuel economy figures.  The owner's manual will probably show a wide range of acceptable viscosities for different temperature ranges.  I would probably go for 0W20 or 0W30.  In the factory oil, the 0 is good for cold start protection, and nothing to be scared of, but the 16 is really thin.  Ok in a new engine that isn't thrashed, but you might want something a little thicker when hot.

I use 5W30 in the Gen3, but it has 50,000 miles on it and the engine technology is over two decades old.

Just poured the above oil, the engine runs quieter now

It's interesting that you have decided the specified oil is not to your liking. Please, if you could run that oil in multiple engines for 150,000 miles in all conditions then strip the engines, check everything is still within tolerance and report back with your findings? Then other owners will be able to consider it as an alternative option for their engines.

Suzuki are trying to get the lowest possible CO2 g/km and highest mpg in standard tests.  Owners don't need to do that.

True, but they have also tested that it does the job required e.g. lubricating the engine efficiently for the life of the vehicle. They aren't just winging it with what they think they can get away with.
Whilst I'm not against people tinkering, this idea that you should change things simply because it doesn't look/feel right to you is silly.

Also:Under the Road Vehicles (Construction and Use) Regulations (Regulations 61(7) and 61A(3)) and the Road Traffic Act 1988 (Section 42) it is an offence to use on a road a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet.The potential penalties are £1,000 for a car and £2,500 for a van, lorry or bus.

Out of interest, is the 1.5 engine direct injection, and is the 0W16 oil API SN or SP?  The Ecstar 0W20 is SN but the latest SP has some advantages for GDI engines.  I can't find a spec for the 0W16 anywhere.

I believe its a direct injection. My post above for what I put. And here is some info for the 0w16
