Keep my 2010 F150 or get a new car?

So I'm thinking about getting rid of my truck. I'm only getting 11mpg and my payments aren't really has low was I would like. I just got this truck back in January. I'm in New Mexico right now so everything is kinda spread out (distance from towns and cities). I'm was looking into a Honda Civic Si. I could get a brand new one cheaper than my used truck. I know it sounds silly to ask other people for stuff like this but it's good too see other people opinions.

It's always better to keep your current vehicle. Do you do a lot of city driving? If so, no car is going to be great on gas and it's fine. If you are a lot on the highway, you should take it in to a mechanic, you might have a fuel leak or something.
