Just looking for opinions here! What type of fuel does everybody use? I have a 2016 lounge with a 1.4 engine, I had read somewhere that it advised using premium fuel?

500 (USA) Best fuel types
always use premium 91 octane min. never use off grade fuels texico chell those kinds of brands it does make a difference in the long term. premium brand have state of the art cleaners and additives off brands don't that is why they are cheaper but you get what you pay for. if you live at high altitudes definitely buy the best you can i live at over 6000ft cheap fuel gives me a ping in my valves. fuel related issues are totally preventable for the most part 
I had no idea that the octain rating in the states was that low? Over here in the uk the lowest you can get is 95 RON with the premium stuff going in at 98 RON. not sure what the rest of Europe has. We havnt used an octain level that low for 15 odd years now.
Thanks for the input! I spoke with the dealership shop foreman and the owner about this issue today and they both were in agreement about the negative effects of alcohol in fuel. I've just recently filled my tank for the first time with alcohol free 91 premium and intend on pampering my fuel system from here on! They also advised using BG 44K fuel additive, any experience with that? I've used the BG oil additive in my Toyota and was impressed with the results so...

Your manual will tell you what fuel type is to be used. There is no harm in running 87 octane. The 1.4L Multiair has a very good knock sensor and will pull timing. I've run 87 octane in my Abarth without any issues on stock tune in Sport mode and regular mode without any ill effects. Sure you're not going to get the most power out of it, but there is no harm in doing so. The manual even states minimum 87 octane.

"This engine is designed to meet all emis-
sion regulations and provide satisfactory
fuel economy and performance when us-
ing high-quality unleaded “regular” gaso-
line having an octane rating of 87. For
optimum performance and fuel economy the use of
91 octane or higher is recommended.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required.
Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience these
symptoms, try another brand of gasoline (with the ap-
propriate octane rating for your engine) before consider-
ing service for the vehicle"
I use 87 regularly when driving from Ontario to Nova Scotia and back (1800+kms one way in normal non-sport mode). The gas savings is worth it.

Note that Octane ratings in the USA and Canada are based on the AKI scale while in UK and Europe use RON. AKI numbers are 4 to 6 units lower than RON for the same fuel. American fuel is a little lower than Eurpean but not as muach as it appears. The tuning of north american cars is normally adjusted to suit (automatically of most modern cars). That said I have direct knowledge of high perfomance european cars on temporary import having melted pistons when run at high power at altitude.

I found this in my owners manual...
