So, around the beginning of October, it seems my VX's gas mileage took a turn for the worse. Now, I could blame it all on winter blend fuel (ethanol) but it just seems to drastic, imo.

I always, always reset my tripometer when I fill up. And typically, I would get about 240 miles per tank. This was normal for me with the lift and roof rack, etc. But now my VX is right about 112,000 miles old, and I am getting about 190 miles or less per tank.

I'm still burning oil, no more or no less than "normal" and I am not feeling any performance loss or getting any CELs. The only thing different, is my VX doesn't like to start up like she used to. Normally, I would turn the key and vroom. Instantly my VX would fire up. Now, she labors a little on start up, a little skipping and then she runs smooth and normal. I recently got an alignment and my tire pressure is good. I will be needing new tires sometime soon but they are really ok for now.

So, what do you all think? I am thinking about changing the O2 sensors, possibly installing a new CAT, cleaning/changing my EGR and injectors. But with no CEL codes coming up, I feel like I could just be grasping at straws.

Or should I look at something else? Perhaps my brakes are dragging or something like that? I've checked my hub nuts and loosened them a little, as they were a little tight, but that has changed nothing.

Anyway, I just can't imagine ethanol is the reason, but maybe it is?
