One thing you can do is get a K&N air filter, they usually boost your power and increase milage a bit. Plus they have a million mile warranty, you just have to clean them every 50,000 miles or when they get dirty from driving through areas with active burning fires.
Second, when you get an oil change go synthetic....but not some cheapy off-brand but a big name that will let you go 7500 miles between oil changes.
Third, watch the accelerating, lead feet burn up the gas a little faster.
Fourth, letting your car idle for long periods of time is pointless. With new cars these days you don't have to let them sit and warm up on a cold morning like our parents had to when we were growing up.
Fifth, the bozos out there that say 55MPH is the most efficient speed to drive are full of it. Every car has it's own most efficient speed. That speed could be anywhere between 55MPH to 80MPH. For example, if your car does 2700RPM at 60MPH and 2800RPM at 70MPH, then 70MPH is the more efficient speed. That's 16% more speed for only a 4% increase in engine demand. For SUV drivers your most efficient speed os going to be lower than a sedan because of its shape. An SUV is a big box, and the last time I looked airplanes aren't made with big flat noses.
Sixth, tailgating may seem like a good idea but think of how often you have to brake and accelerate to keep that tiny distance constant. That in itself negates the benifit of reduced drag. Keep a few car lengths back but also look a few cars ahead of the car in front of you as well. The less often you have to hit the brake the better.
Seventh, the fewer the lane changes the better. Swerving all over the place just hurts you more not to mention eats your tires up faster as well. Of couse get around the slow poke doing only 57MPH in the #1 lane!
There are a few other things I do but I don't know if they're legal or not so I'd rather not list them here. I DON'T run stop signs, that includes coming to a COMPLETE stop every time.
There are additives out there but they don't give much of an increase in milage at all. If you get 30MPG and got 2MPG better on a 10 gallon tank at $3 a gallon that saved you $2. But remember, you have to figure in the cost of the additive too and most of them are one shot wonders...you have to add them to every tank of gas. So if it costs you $5 for the additive then you actually lost $3 instead of saving any money at all.
These are some of the ways I've increased the MPG on my 2000 Camry from 27MPG to 36MPG. I'm going to shoot for over 40MPG next, that would be better than most hybrids here in the US.
