I'm here b/c I want to make the mileage better. Seems like people are talking alot about tire pressure. I check mine, and got it at 32psi all around, guess I could put it up to 35 or max? Got to read up on exactly what a hot air intake is and what to try first.
If you're serious about it - and your gaslog seems to prove that - get a ScanGauge before you do anything to the car. That's my personal opinion because any mods done to your vehicle should be tested to death to see if they are any benefit/detriment.
My tires are rated for 35 psi, but I boosted them to 40 and the hot weather pushed them to 44 today. I haven't noticed any difference in the ride and they haven't sprung any sudden leaks. There are many guys on here running high psi and they haven't had problems, but remember that you do all tests/mods at your own risk.
I agree that if you really want to see big gains in milage a scangauge or other type device is a must. You can improve your milage without having to spend a lot of money just look through the forums and start working on your driving techniques, that doesn't cost a thing, then you can start with the aero and other mods.
I would recommend switching all fluids to synthetics. More power, getter drivability especially in the cold, longer coasts, longer life of your car, cheaper since they last longer, better for the ecology.

Hi I live in South Africa and have an Aveo sedan LT 1500 8 valve manual transmission. It is underpowered and thirsty. It takes a long time to fill the tank to the brim so one tends to get incorrect reading when trying to work out fuel consumption. Also the suspension is noisy. It has much more room inside than a VW Golf or Polo.
