    that got 12 mpg with me driving an 16 (in town) with my wife driving. Go figure.

    Or an egg on top of the accelerator....

    Don't suggest that to our Aussie friends! Placing ostrich eggs on the accelerator will cause the vehicle's speed to max out rather quickly! :-)

    Drive like you have a egg on your gas peddle and use the brakes as little as Antisapate stop lights) possible.
    As for testing gismos, test them on a machine/dyno, since driveing to work is not a good way, because you may hit more signals or heaver traffic on ome day more then another. Also you have to figure in the cost of the devise, such as $60 or so how much gas does thay buy.
  • I have real world data back from my 2000 Chevy Tahoe Limited ("old" body style), 5.7L V8. I drive a consistent mix of city/highway driving. Before Tornado, I measured my mpg at 14.9 with my previous tank of gas, although I have been known to creep up into 15.0 to 15.5 on some previous tanks.

    Keeping driving habits the same, my first tank of gas post-Tornado was 14.9 mpg, my second 15.3 mpg. I didn't consider this statistically significant or sufficient to justify the $70 investment, so I disconnected the battery longer than they suggest (5 minutes) to "reprogram" the computer, I presume for air-fuel mix. After reconnecting the battery, started and idled longer than they suggest (2 minutes). So my third tank of gas after the battery trick was 15.3 mpg.

    I had similar warning bells in my head from reading their marketing material, as previous posters in this forum, but was willing to run my own test under the 30-day money back guarantee. So I still have almost 2 weeks of the 30 days left and plan to remove and return for my refund immediately.

    Let's say that the device does allow great improvement for the vehicles listed in their marketing material. Even if that were true, there is not a vehicle of the 2000 Tahoe type with a Vortec engine that's represented on their table of example improvements.

    So I won't be installing it on my wife's 1997 Suburban then either, as it has the same engine type.

    For Tahoe owners in my area wanting better gas mileage - my advice, cure the lead foot up to your stops and out of your starts. Where are you really going when the light in front of you is still red?

    "miracle cure".

    The only way to lose weight is not through some magical pill or supplement, but through proper diet and exercise. Even though most people know this, the diet industry still grosses over one billion dollars a year.

    Same for the automotive "economy and performance improvement" market.

    Gas is $1.81 in my area for regular, and Tornado and other gizmo companies are starting to crank up their ads again.

    Pay attention to the "up to" language when you read the mpg claims :-)

    .. your best bet would be by powerpack kits (includes filter, catback, headers, etc) by gale banks, and if you have a gas engine you still won't have such great mileage. but at least you'll have good power :) however, diesels get huge gains in both mileage and power.

    here's a testing for the chevy 5.3:
    24 hp and 22 lb-ft at the *wheels* .. and only %2 better mileage.

    I find the tachometer in my auto trans car helps me to get better mileage by making me ease off on the gas so trans will upshift sooner into a higher gear but without lugging the engine.Previously thought tachs for an auto trans car was useless(learned to drive when auto trans had only 3 speeds), but with modern torqueless engines having 4-5 sometimes hard to feel speeds and todays quieter engines, the tach allows me see what gear I'm in and adjust the gas.

  • If you want to use less fuel, the "formula" is simple. Stop purchasing pick-up trucks and SUVs. Purchase vehicles with four cylinder engines that get 30+ MPG. I have a 2003 Honda Accord with 39,000+ miles on the clock, and I never check the mileage. It is what it is! But I laugh at my friends, when they "fill up" their big SUVs. A "fill up" for me is $34.00, (17gals X $2.00). A "fill up" for them is $50.00. I get 30+ miles per gallon, (based on the manufacturer's advertised ratings). They get 15 miles per gallon. But on the other hand, they have the "Big Bad Image", and "image" is everything in our society! So, if they want the "image" let them "pay-for it"!

    Any new gizmos out there?

  • tidestertidester Posts: 10,059
    Has anyone tried the "Fuel Genie" or the "Platinum Fuel Saver?"


    tidester, host
  • steverstever Posts: 52,462
    Maybe if we try a new name and mothball "The accessories to improve mileage and extend engine life."

    Does anyone know anything about an old cruise control called Pacesetter? I need info such as wire connections and some troubleshooting.
  • Has anyone tried or even heard of Blue Sky?

    If you want to save fuel, and in the process cut down on your fuel bill, purchase a vehicle that you truly need, not the one that you think you need or want. In my travels, I see people driving BIG SUVs with only ONE person in the vehicle! Unless they have a BIG family at home, or a business that requires then to carry large articles, I think the SUV is a little over kill! But, if they can afford $52.25 for 25 gallons of fuel, at "fill-up-time", then more power to them! Most of my family drives 4 cylinder vehicles, and being in the automotive business, we can drive anything that we want. I think that this SUV issue, is an EGO thing with a lot of owners! It is all about image on the road. Whatever you drive, the trick to getting maximum performance and mileage out of your vehicle is frequent maintenance, and that translates into keeping the interior of the engine clean, which then translates into frequent oil and filter changes. A clean engine has less friction, and less friction means that the engine uses less fuel. Now, I know that the vehicle owner's manuals encourage long oil and filter change intervals, but this is not what I personally believe, so I have set a 3,000 mile standard for my vehicles. ----- Tanya
  • Hey whats going on? Im also an owner of a 2000 Chevy Tahoe Limited. I tried the same trick with my battery and got the same results while replacing a bad fuel pump pretty neat huh? Also I changed my Air filter to an K&N filter and noticed a difference in my RPM's they did not rise as high as when using traditional air filters. I choose not to change the whole intake because the Vortec is already at its best but it did help. I also changed exhaust not to one of those exhaust that make a lot of noise and no benefits. I changed it to an aftermarket exhaust made by Midas with a lifetime warranty and it sounds good!!! Its not overly loud but you know you got a V8!! You will also notice the HP increase especially when getting on to an on ramp or pulling a trailer. Hope you enjoy your Tahoe as much as I do mine and thanks for you time just wanted to share some of my successes with my Tahoe.

    Yes. I tried the "Platinum Fuelsaver" in a 1975 Jeep Wagoneer with the 360 engine. The good news is it's easy to install and it eliminated the knocking because of regular gas. It may gave slightly improved gas mileage. The bad news is that after about 6000 miles it clogged up and would not unclog and the reservoir collapsed due to the heat under the hood. Looking back I would still buy one if they would guarantee the parts for a reasonable period of time.

    Maybe we need to take a page from the hybrid hypermilers and suggest some non-gizmo tips, like keeping the tires inflated to spec.

    the reason that an after market ignition system could provide better gas mileage is because it would have a higher voltage output causing a bigger spark in turn causing more complete combustion leading to more power which means less throttle less gas and better gas mileage.

    Wow! I get a reply - 4 years later!

    Thanks - though I think it's still an open issue as to whether higher voltage can produce more complete combustion.

    Have anybody tried fuelblast cards?

    How does it work?

  • Hello Steve,

    I am new to this forum and the above title caught my attention. I do have an item that is NOT available thru your AUTO PARTS SUPERMARKETS. AND THIS ONE WORKS. It is a LOCKING GAS CAP that is made in Germany. It works on the
    DURAMAX Diesels and other GMC/CHEVY Trucks.

    This little gizmo (for the new low low price of only $197!)is supposed to generate hydrogen (FROM ORDINARY TAP WATER!!!) and then inject the hydrogen into the air intake or air cleaner for added fuel economy.

    Question - IF the thing actually produces hydrogen(?), wouldn't the hydrogen react with the oxygen coming into the intake and produce.....WATER?

    If this is the case, isn't this just a really, really complicated water injection system?
  • Recently, an import tuner buddy of mine convinced me to install a ground wire system on my 98 4Runner. By reducing the impedance flowing through your vehicles electrical system you improve performance. For 75 bucks I bought one which my pal installed in less than 20 minutes. Results? Added life to an ;) engine which has 140k on it, starts easier AND got a 3 mpg increase in gas mileage. For the price and ease of installation you can't go wrong. Check it out!
