2012 Yaris LE Poor Mileage

[sjo102784]

Hi everyone, I've been looking through the forum for an answer but couldn't find anything that could directly help with my issue.

I have a stock 2012 Yaris LE and seem to be getting low MPG compared to other Yarii on this website. I regularly get around 30-32 mpg. It is an A/T, serviced at all required intervals, and I monitor tire pressure (according to the door panel indications) and all fluids in the car.

I realize that how I drive impacts MPGs, and I drive fairly slow (not accelerating quickly, not driving above about 65mph on the highway/interstate), I drive like an elderly person, and my driving is about half highway/interstate and half city driving. The car was stickered at 30/city and 36/hwy. Are these numbers accurate to other Yaris drivers with 2012 or newer? My current tank is getting 32mpg.

I was also considering some basic upgrades to possibly help with MPG. Any advice as far as air filters or air intakes? I noticed another thread with a DIY K&N filter upgrade and a cold air intake. Is one better than the other? I realize the cost of an air filter is lower than a cold air intake, but would a cold air intake result in higher mpg? Also - are there any spark plug upgrades I could do to improve MPG?

If you guys have any other advice I'd appreciate it. I'm trying to exploit the Yaris as best I can to get better MPG!
