I got my 2013 XC in October but the few times I've been able to get it out between then and now it seems to go through gas really fast. I've been using 93 which is the next up from 89. As I've been reading, I see that some will use 89, but I'm just trying to see if this is a common issue. I'm going to check my air filter to see if it needs to be cleaned (from what I read, it's a reusable). I'm still totally in love with it, but I don't want to let a possible issue continue. A friend said I need to put a power commander on it, which I'm not looking forward to that bill, but if it'll help in the long run, I guess that's a route I'll have to go. I appreciate the advice!
