Do Those Gas Saving Tornado’s Work?

save your money, they don’t work.

Nope.
Product that saves gas: something that your engine can use instead of gas, or in combination with it. Such as ethanol — which is blended into gas here in Houston by law. However, it’s a lot less efficient at burning than gasoline, so your fuel efficiency overall goes down, though you’re burning less actual gas (15% of it replaced with ethanol) — so it’s somewhat debateable if it’s actually useful or not.
Other people change their cars to run on biofuels, such as distilled from used restaraunt oil and grease. However, this does take some significant work and up-front expense, plus the driving costs to go to participating restaraunts to pick up their grease (and you might be out of luck if you have other people doing the same in your area).
Other than that? Combine your errands to drive as little as possible. Drive slower (every bit faster over 60mph makes you less fuel-efficient, generally). Keep your car in good working order. Keep as little weight in it as possible (the more it weighs, the more gas it takes to move it). Drive a smaller car. Carpool.
There is no magic pill, just people trying to take advantage of those looking for one.

That’s the problem, like Bull Dog says. How would you ever hope to measure small changes in fuel mileage accurately? And 1 mile per gallon is not a small change to the engineers that design the cars I’m sure. If you had 5 or 6 things that improved the mileage that much, you would have a significant improvement. So doing a lot of little things that you know from basic science must improve the mileage, albeit each one unmeasurable is worth doing, like putting the maximum air pressure in your tires and using synthetic lubricants because they all add up to real improvement. Here’s an old gas mileage gauge design that reminds you to keep your foot off the acclerator pedal:http://www.jcwhitney.com/autoparts/Searc…

I’ll pose this thought to you, I’f a devise as simple as this was a sucsess at increasing fuel milage why wouldnt the car manufacturers install them or make a version of there own to boost their milage on new cars to sell more of them? they could but them in mass quanities from tornato and pay penny’s on the dollar or buy the company out whole and have them as their own. Fact is no they dont work they simply atomise the fuel a tiny bit more durring higher rpms and I supose if you drove 100 plus miles a day and at 85 miles an hour it may benifit the mpg’s a bit compaired to the same speed and distance with out.

It kinda works, but it isn’t going to be a massive diffrence. You might be lucky if its 1mpg. I’m not kidding, we tested it for my automotive class back in highschool. The concept for how it works is correct but it needs more air pushed down in it to work.

No – this device does not work at all. The idea that it creates a ‘tornado’ of air is true, but this does not affect gas mileage at all.

no

Due to rising gasoline prices, everybody is scrambling to make their gas last longer or get more bang, but all these ‘gas saving’ devices do is drain your wallet. All of them.
None of these ‘gas saving products’ work as claimed. NONE.
Not the ‘pills’ (chemically, they are nothing more than composed of mothballs). Scams like ‘pills’ have been used since the 50′s to sucker a victim.
Not the “burn water in your car” devices. If the claims made about them were true, they would violate the 2nd Law of Thermodynamics (ie, you cannot recover more energy from breaking down water into ‘brown’s gas’ than you get when you ‘burn’ it in your engine. It’s a hoax and lie. You will NEVER be able to hook up a device to your car battery, and ‘break down water’ in sufficient quantities to run your car on the resulting hydrogen.
Not the ‘tornado’ devices. It does not ‘force’ more air into our engine. Only a turbocharger or supercharger can do that. The fact is that placing one of these in your ‘intake’ is useless. After the air enters the throttle body (intake) any ‘vortex’ imparted by this $30 rip off is LONG GONE because after passing thru the throttle body, the air starts swirling around round anyways from hitting bends in the intake manifold! They also fail to mention that it will have NOTHING to do with ‘mixing’ the air/fuel mixture better because the gasoline is INJECTED in the cylinder or just prior to that at the valve where any ‘swirly’ effect from the ‘tornado’ is useless.
Remember, most of these products are sold by those who ‘swear’ by it and ‘claim’ it works. They will say that the devices have been ‘scientifically’ tested but offer no proof as to WHO tested the device, how it was tested, etc. The only proof that could be believed would be if Consumer Reports were to test such a device (and they have and they don’t work as claimed) and offer true, unbiased results. Also remember that many of these devices can be sold thru muti-level marketing scams that get you to buy the product, then suck you into selling it to other unsuspecting half-wits who don’t understand the science or physics involved in the scam device.
Again, they are scams, rip offs and cons.
If you want to save gasoline, use the following tips:
1) Keep your car engine properly maintained: clean air and fuel filters, pcv valves, etc. This also means keeping the oil changed at regular intervals, and USE SYNTHETIC OIL. Use the recommended viscosity (I use 5w-20 in my Hyundai, or 0w-20 when I can find it, of Mobile One). I also use ROYAL PURPLE (TRUE SYNTHETIC STOCK OIL). With a great oil filter (NAPA GOLD) and Royal Purple, you CAN go 5000-7000 miles between changes. Or use a lesser quality and change at 3,000 miles. Also, if you can use different plugs, try the Bosch Platinum +4 plugs. They work great.
2) Keep your tires properly inflated. Tires that are under-inflated are harder to ‘roll’ down the road by the car’s engine, and use more gas, and wear out on the edges. If your tires are over-inflated, they will wear faster in the center, not give you much better fuel economy and ride worse.
3) Drive the speed limit, and maintain a steady speed (use cruise control if you have it). If you drive a bit slower, stay in the right lane!
4) AVOID jack rabbit starts and coast to a stop to conserve your kinetic energy. If you hit your breaks hard to stop, you burn up that motion as heat, wear your breaks, and feel stupid when, had you just let off the gas and coasted, the light changes to green and you have just come to a complete stop.
5) Remove excess weight from the vehicle. Extra weight means extra gas to accelerate, etc. Tool boxes, chains in summer, etc all add up to extra weight.
6) If you want to increase the volumetric efficiency of your engine, consider a less restrictive air filter or cold air intake system, and unrestrict your exhaust (performance muffler or dual exhaust). When I installed a K&N High Flow Air Fiter on my old 1990 Isuzu truck, and when I pulled the stock muffler off it last month and replaced it with a MagnaFlow muffler, gained about 3 mpg and probably 12 horsepower due to the fact that engine can breathe easier with a less restrictive intake and exhaust system.
7) Keeping your car clean and waxed will help as well. A clean and waxed car ‘slips’ thru the air easier and offers less resistance to the air.
Remove anything that adds drag (overhead ski racks, luggage racks, antenna flags, etc). Anything that is hanging off the car and can be ‘hit’ by the airflow can reduce your fuel economy. It is true that putting the tailgate of your truck down or using a ‘flow thru’ tailgate does improve fuel economy, as does using a Tonneau cover over the bed.
9) At highway speeds, use the A/C. The A/C will offer less ‘drag’ on the car’s engine than the air-induced drag caued by having open windows and vents.
10) If your car is out of warranty, consider using a modified ‘chip’ or reprogrammer to change the engine parameters to better your fuel economy and performance. NOTE: Don’t use these if your car is still under the mfg warranty as doing anything to modify or “hack” your car’s cpu WILL VOID any manufacturer warranty.
11) This relates to the exhaust system. While I cannot suggest or recommend removing a cat (catalytic converter) in your exhaust, suffice to say that if your car has over 100,000 miles on the odometer, the cat is not working anyways. To ‘test’ whether or not it is working, buy a ‘cat test pipe’ and replace the cat with a straight-through bolt in pipe. To “TEST” of course. Only for testing. I found the cat on my 1990 Isuzu to be rattling and of little use. I removed it and I found it to be pretty much non-functional as the contents that did move about poured out, and it was clogged inside from rust, etc. When I ‘tested’ to see if the cat was a problem, I found that I got one more mpg when I removed it (my truck has 184,000 miles on it). I will replace it soon, of course, when my tests have been concluded.
12) Do NOT use a higher grade of gasoline that your car manufacturer recommends, as it will NOT enhance performance and cost you more.
13) Use E85 (ethanol) when you can. It does cost less per gallon BUT you also will get less ENERGY. With only 2/3 the energy of gasoline, ethanol costs more per mile. You would need to burn 1.5 gal of E85 to get the same ‘kick’ as from one gallon of gas.
A gallon of ‘average’ gasoline offers up about 116,090 BTUs of potential chemical energy, while a gallon of pure ethanol alcohol is about 2/3 that. That’s the downside, as your fuel economy will be less (you will pay a bit less for E85 though). The positive side is that you’ll be burning less gasoline (15% instead of 100%) and help kick start the alternative fuel industry and infrastructure. With less demand for gas, the price WILL come down. Ethanol is here and wont’ go away, so you might as well embrace it.
If your car was not designed for E85, (85% ethanol, 15% gas), you can get a kit that modifies the spark, timing, etc to allow you to get the best bang you can for virtually any vehicle. A real ‘ethanol’ based engine, with higher compression, can really take advantage of it and not lose any efficiency.
14) This is a good one. Plan your trips so you don’t have wasted gas. Look ahead and anticipate lights (that relates to coasting to a light by just letting off the gas). Anticipate the speeds you need to make all the lights green (remember, when you are sitting and idling at a traffic light, your MPG is ZERO. If you know certain streets are crowded at certain times of the day, avoid those times. Make right turns whenever possible. YES, it is true: UPS saves millions of dollars in fuel costs by ELIMINATING “LEFT TURNS” (ie waiting to turn LEFT at traffic lights) from their drivers’ routes. The right turns are easier and often involved a momentary stop, and remember that “TWO WRONGS do NOT MAKE A RIGHT, but THREE LEFTS DO!”. You can drive a BIT longer by making more right turns to end up going LEFT but it is tried and proven fuel saver. http://www.nytimes.com/2007/12/09/magazi…
15) Take alternate, less congested routes that, while may seem to use MORE gas because it’s bit longer, use LESS gas because you don’t get stopped by traffic lights, etc.
16) When you are detained or stopped in traffic for more than a couple of minutes (the average traffic light now), say at a train crossing or because of an accident, shut off your engine. It does not take more gas to restart the warm car, and fuel injected engines do not waste any fuel on start up.
17) Consider ‘upgrading’ to a more fuel efficient car. Unfortunately, that is what most people are doing now and that is causing auto dealers to tack on about $3000 to the price of a fuel efficient used car as well as new cars. You pay more up front to burn less fuel. Sort of like an oxymoron, but again, the end result you want here is to USE LESS GASOLINE.
18) Carpool when you can, or use public transportation. It’s not a lot of fun, but it certainly uses less fuel.
19) Ride a bike or walk. I live within 7.5 miles of where I work and can get there in 30 minutes or lesson a bike. Consider gettting an electric bicycle, or a “scooter’ or motorcycle.
20) Don’t buy into all the gas company hype. All your gasoline comes from one place now, where only each company’s ‘special blend’ of additives are added just prior to delivery at your local gas station. Shop for price. A few cents might not seem like a lot but it doe
