Now that the $4.00/gallon of gas communism is upon us I am feeling it more than ever before how my 2004 Forenza performs in the city. Its not too bad on the highway but its terrible when driving around town. I got a K&N filter a year or so ago (no difference at all in gas mileage) and get the oil changed religiously every 3000 miles. I'm also finding my oil is leaking a tad bit at the start of every oil change and for some time after but mechanic says thats natural for that too happen. I get roughly 200 miles for every $30 (used to be $15-$20) if driving in the city mostly and about 300 if highway driving usually. It averages out to about 22 mpg or so which isn't very good nowadays. Car only has only 36K on it and I;m stuck with it for a while. Is there any product, modification, or anything i can do to increase the city gas mileage on the car??? I have been emailed about a product called Ethos which is used in California. Any others? How is Ethos for those who have used it? Thanks.
P.S. Please don't suggest the obvious things like less weight in trunk and all. I have tried all those forever!
I try not to go over 3000 rpm in the city, and leave the AC at a lower temperature. Make sure change your O2 sensor and air filter, inflate your tires to around 35 psi. This all works for me since I get 33-34 mpg on my 04
How on earth do you get that? You've gotta have something modified right? I have a K&N air filter. Should I clean that even tho it says you dont have to? How hard is the 02 sensor to change? Thanks for the tip on the RPM's. I rarely use the air as it is b/c i know it slows engine and i cant get as much horsepower when its on.
As long as you drive with the same habbits then anything that frees up the engine. Intake, exhaust, UD pulley, grounds, ect. Lighter wheels, tires, brakes, better tranny fluid, lowering springs, ect. For me it was easy to get 26mpg.
Yeah Ive thought about getting one of those intakes (like the K&N typhoon or something) but i think Id have difficulty installing it. Heard its hard to do. Do you suggest any one that you know too work btr than the others? Should I get a new exhaust if i get the new intake?
the O2 sensor is not hard to change at all, all you got to look at is the exhaust manifold and find the sensor with 4 wires leading from it. That thing needs to be changed every 50k or else it starts to ask for more fuel to be consumed. Other than that you should just ease up on the gas pedal and slowly creep up to 2500 rpm until it shifts. When you see a light turn red at a distance just let go of your gas pedal and let it roll up until you reach the light. Im telling you its not bad when you use this. I am usually charging a cell phone and using a computer whenever I commute, so it should work for you.
By the way I just returned from a tour in Iraq, where even people over there are trying to reduce their consumption. Most of them use 4 cyl vehicles and believe it or not I have seen about 4 white '04 suzuki forenzas driven by some folks in the haditha area. It was quite funny since I have met one of them and they said they loved their car.
If you're driving in city, dont even turn on the A/C at all. that burns fuel. Roll down the windows maybe half way if it's hot, because that will be enough to cool down the interior of the car. And theres no 'wind drag' from the open window because with city driving you wont be going fast enough.
And yeah, dont rev that engine. That's plain common sense. :3

on average i get about 26 mpg...and i dont drive like grandma. i didn't read over the responses that people sent, but heres a list of things that you can do to help
1. keep your rpm's low by shifting or driving slower. it might take you an extra 10 minutes to get somewhere by driving 65 rather than 70+, but your RPMs will be lower(which means less gas consumption)
2. windows up. with your windows down, you're creating drag. at lower speeds it doesn't matter as much, but at highway speeds, it makes a difference
3. A/C. run your air conditioner when you are already at speed. when running, it creates drag on your engine. i suggest you don't run the a/c when you are accelerating or at a stop.
4. performance mods. simple things like intake, exhaust, ud pulley, lighter wheels, and lighter body parts will reduce strain on the engine. more freed up ponies will make it easier for your car to accelerate...HOWEVER, things that increase the amount of fuel into the engine (cams, fuel pump, injectors, etc) will make your mileage worse.
5. avoid accelerating up hills. get to speed before climbing hills. going uphill is more difficult than on a flat surface...
2. Install a system that converts water into a Hydrogen/Oxygen gas
I'm doing #1 already and I've increased my MPG's from around 24-25 a gallon to almost 32mpg's. I'm currently building my Hydrogen/Oxygen gas system and will be ready to install it soon. I've just got to find the time to get the rest of the parts and put it all together.
