Hey y'all, I'm driving a 2014 Chevy Spark. I've had it for a year and a half now and I'm wondering what y'all have done to try to push that MPG to the 30somethings? I was at 32 when I drove off the lot then it dropped to 25 until I got my fluids changed and my transmission switched out. It started pushing a flat 29 then. Now I'm pushing 28.9 and unsure what I can do to raise it instead of drop it. I've tried fuel injectors but they did nothing. What else can I do?
I drove a lot of city, then I did a cross country move and now it's mainly highway I drive and would love to get that
