Wide distances with the 1.2 8 V

Good morning dear Fiatisti, I am concerned today with the question whether you can travel with the 1.2 8 V engine long distances from 500 to 1500 km without any problems. Has anyone had any experience in this regard? The engine has little engine capacity and not much nM, 102 nM to be exact. Is there a speed that you can recommend? I imagine something like 110 km/h in the long run. Is this possible? Which oil is recommended? And what is harmful for the engine, except full force in the long term, bz w. How long should you drive this MOtor without any problems? As a classic travel recommendation is safe, new oil, new spark plugs as well as air filters, inclusive control of all liquids, suspension parts? Greetings from the Swabian province
