Getting Better Gas Mile-age...

[FizzNakLe]

I've been considering buying a Plasma Booster and new ignition wires (8mm) because they're suppose to give you better gas mileage, has anyone bought either parts and have they worked?
Are their other ways to get better gas mileage? I don't want another car, I just want to not spend $25+ to fill the tank everytime

i laugh at $25 per tank.. even my z3 takes $29 to fill its tank and its tank is smaller then my e30's.. where the hell are you filling up, i want in...

should see the bill of when i fill up my demo h2's.. try 32 gallons at (last i checked) $2.45 USD per gallon.


i never saw better milage with high performance ignition...(msd or crane,own both full systems)

if you want better milage, use less throttle. and restrict your airflow into your motor and install smaller injectos.

restrict airflow? But I thought you increase gas mileage by getting less restrictive filters like K&N. or am I comletely wrong and thinking about something else?

I just put 8mm plug wires on and my gas mileage went from 19.7 to 21.3 ---so a little better. I would recommend them for sure...

What car do you drive and what state of tune is it in? How many mpg are you averaging. Have you done an alignment lately? Too much toe in and you would be adding rolling resistance increasing fuel cosumption and shorter tire lifespan. Are you carring around uneeded weight in your car? Heavy aftermarket wheels? Have you been driving around with the a/c on and or added stereo amps? Take it easy on the gas and cruise around instead mashing the gas to get from light to light.

the more air you have the more fuel will be burned to run at stoic. if you have less air, you dont need as much fuel.

you will make less power, but old school days of carbed motors used restrictor plates to get better MPG on their massive v8s (gm and ford did to an extent at least with some of their motors in the 70's).

i want better gas mileage too! maybe i should not fully open the throttle all the time tho. . . used

[ldsbeaker]

I used three tanks of gas last week. (87 octane) and averaged 30 mpg for two of them. The second tank I had included about an hour and a half in stop and go traffic, so I only got 26 mpg. The first and last tanks were back and forth to Virginia for vacation. The last tank, I sped the whole way home, frequently had to pass people (i.e. getting into the gas) on two lane roads, and still had awesome gas mileage.

This what I have done...

Changed the gas filter
Changed the Oxygen sensor
Bought a new air filter
Hot soaked my car a couple of times
New Spark plug wires, distributor and plugs
6 new Feul injectors

Thats all i can think of as of right now...oh don't drive like a jackass

hotsoaks clog your cats. dont do them too much or you'll end up fucking them up and needing a new cat.

one word: drafting

[offabroadway]

If you want better gas milage.... buy an E!!!

Seriously, on my last tank, I got 23mpg in the city, with an AUTOMATIC. Considering my driving habits (hair-trigger throttle driver right here) thats pretty damn good. I'm trying to check how much more I get out of her by babying her this tank.

Unfortunately, my odometer has stopped. Damnit.

Yea you are probably right but my cats are 15 years old so they are probably clogged already. Thanks for the warning

[offabroadway]

You'll be able to tell, noticeably, if your cats are badly clogged. The car will NOT like to be revved up really high and when cranked on continuously will eventually just stall out.

Just remove your cat if you live where you can get away with it. When the previous owner replaced my exhaust system, he went all stainless, performance system, no cat. Sounds, and performs, awesome. It's just slightly illegal in places with smog tests.

I dont do anything to get better gas mileage, but on logn trips I do try and utilize drafting. I'd like to think it actually helps, who knows.
