Can't break 40MPG... - Page 4 - Toyota Yaris Forums

also make sure your air filter is clean and installed properly. I drove around after hitting up the dealership for an oil change, etc.. and I kept hearing my airbox sounding like it was hallow. At first I thought it was simply a new air filter with less restriction, but the hallowness turned to howling at midrange rpm's, finally when I got a chance to check under the hood it turns out the airbox was completely open!

luckily the airfilter was jammed the hell into the top where the air gets sucked into the engine, but if it had fallen out my engine probably would have been ruined in no time. moral of the story is people suck and are lazy.

well, actually that's not the moral, but still true-- the deal is I ended up getting a huge hit on gas from that, and ended up with an average of under 32mpg, from my usual 35sh. All from a few days of this airbox conundrum. So the filter plays a huge part in gas mileage, and a clean and happy airfilter+box is a clean and happy car.
