Lets face it... a lot of people on the forum purchased their Elantra for the great mileage it gets. Obviously this is a topic of debate for some, but I personally have been happy with the mileage I've been getting.
For me my Elantra is a second car... I purchased it solely to keep miles off of the 6.2L v8 I was driving every day and safe a few bucks on gas.

My Elantra looks great, is comfortable, and gets the job done. It's not perfect... but then again, no car ever really is. That's why I like to (tastefully) modify my cars to make them better suit my needs. For my Camaro it's all about performance.... bigger, better, louder, and faster. For my Elantra, it's all about seeing how far I can go on a gallon of gas, while still maintaining comfort and styling.
There are a lot of threads out there debating fuel economy. I have read the sticky post (
here), and there is a lot of good basic information out there on the ol' interwebs. Obviously (or perhaps not), there are a TON of factors that go into fuel economy... driver, conditions, weight, fuel, tires, aerodynamics, etc. I personally haven't started doing any mods yet (besides just tint/etc.), but would like to move my 35-38mpg tank average up to perhaps the 42-45 mpg range. I have an idea of what I mods I will do, but my question to the forum is this: What mods are you doing to improve your fuel economy?
