Getting better gasmilage, products

[supper_slash]

Has any one tryed out thowse products that clame to get you better gas milage and hp and torqu.
Like the "tornado" or thouse "magnets" that gose on your gasline, or any thing that you have found to get better gasmilage, ie. home made ideas
Like chilling the gas, or Heating the gas, or anything at all Please post, i allready have good driveing skills, ie no posts about how to drive please.

Did you find any products or ideas that worked, or that did not work?



Sorry about the spelling,

A good tune up and only run as much octane as is required. That's about it.

Engine designers go to great lengths to laminate the airflow and STOP spinning air in intakes. My 96 Impala SS has a screen in the MAF, a vertical vane in the MAF, and a specifically designed air foil in the TB to stop swirling air, so those tornado devices are a gimmick. Removing or altering those devices has shown either no performance/MPG gain, or even in the negative on this particular car. The magnetic "hydrocarbon modifiers" are snake oil, too.

If you want to take it one more level, try some computer reprogramming. The factory fuel and spark trims are calibrated to provide a very safe detonation buffer and minimize NOx emissions. The result is a slightly rich mixture that is a trade off of HC and CO emissions against detonation tolerance and NOx. Leaning out the mix just a touch will provide a slight power benefit, might save you one or two MPGs and probably put your NOx right at the legal limit.

Don't run thinner oils or use special additives to the fuel or oil. You'll spend more on the additives than you will save in gas and potentially mess things up.

You'll also find that winter blend fuels are much worse in the MPG category. They include alcohol which carries some of its own oxygen. The result is that your O2 sensors richen things up to keep an even mix and you use more fuel.

For now, stick to the regular stuff and wait a while on the snake oil fixes. Get new plugs ($5) check your wires for resistance and arcing (free), check coil and ignition output (free at most chain parts stores) and make sure your tires are properly inflated. (free... or 25 cents at the gas station) Resist the urge to buy special plugs with split tips and multiple anodes. EFI engines' computers are constantly searching for the optimum parameters to the tune of hundreds of times per second. You'd be surprised at how much a consistent spark will be more beneficial than a fancy spark that jumps around. If you want a BETTER spark, use an aftermarket ignition system like Jacobs, MSD, or Mallory and fire it through good quality plugs like NGK or Bosch Platinum. Its an investment that can be made for $120-200 and you can check some Neon forums to see how much fuel others have saved with the ignition boxes. You can usually expect 5% or so.

well that is what i thought, but if anyone has any more info on other "Snack oils" that you see out there, please feel free to post your findings.
P.S. i talked to "Jacobs" ignition, and they do not like botch platnum plugs, is seams that the botch dosent offer enuff eletcroid for the Jacobs to get full burn on the plug, they reccomend a good name brand plug with no "Snake Oil" added, IE. nothing special. as for the rest "mds" ect ect i cant say. But Jacobs i have on my CJ-5 jeep And on my Dodge charger, and they do get better gas milage. So Jacobs is not "Snake Oil".

Keep post going, Put your findings on here better gas milage..........

Using the thinnest oil your engine can take will reduce friction and decrease fuel consumption.. You can also buy an oil which have API EC and/or ILSAC GF-2 classification, this means that the oil have shown to reduce fuel consumption compared to a reference oil.
NEVER use any addetives in your oil.

Leaning out the fuel and advance ignition timing will also decrease fuel consumption, but note that fuel injected engines run lambda 1 and running leaner will result in that the catalyst won't work as intended anymore. You can also advance engine timing, but this aswell as the leaning of the fuel means that a higher octane fuel will be required.

sorry to bring up an old thread but with the magnets on the gasline they do work... in THEORY... in practice however they have not prved beneficial. Seriously if they were really beneficial to the cars performance or MPG the car makers would have included them in the design and squeezed some more dough from your pocket.

They don't work in theory, nor in practise. Their only purpose is to make the people that sell them rich.

AMEN. They are magnets, and even if gasoline had any iron in it, it wouldn't do any good. There never was a theory other than, "lets use a $1 magnet on a fuel line and sell it for $19.95 plus $6.95 shipping and handling and I theorize that I will be a billionaire."
