If I want to make my car/engine last longer.

Should I use petrol which has a low vapour pressure or high vapour pressure?

regardless of the fact that all pump petrol would be so similar when it comes to vapour pressure, i doubt vapour pressure really has anything to do with how long your engine lasts.

are you sure your not confusing octane rating with vapour pressure?

higher octane fuel is generally better quality, but there are many other factors that will shorten an engines lifespace
