Does the tornado fuel saver really work?

I was just watching an early morning infomercial on this product. Has anyone here used it? Does it work? The principle behind it seems to make sense.

I would say.....
No

If it worked that damned well auto makers would snatch the patent up in a heartbeat. Auto makers have set gross milage limits they must meet, and to be able to get a MPG and HP increase in an all in one easy to insert object would be quite a good thing for them. Thus, since the Big Boys didnt give it a look I sure as hell wont.

Now, I *may* be wrong, and there very well could be some slight gain. But I think the numbers they put up are optimistic at best.
 
Shockwave is 100% right. If there were a means of improving mileage this cheaply, every automaker would use it, particularly the ones who struggle to meet their CAFE standards.
 
Rule of thumb to keep in mind about these devices is that if they really worked, with the pressure auto manufacturers have on them to increase fuel economy & hp, they'd have already included them into their design.

I have noticed that over the last few years, air intakes & related plumbing, as well as exhaust system diameters have increased @ least on the stuff I've looked @.

A LOT of information and an involved read! However, if you invest some time in reading the full text, you will come out of it wiser 😉

Hmm interesting reads. Oh well I should have known, it sounded to good to be true. They do a real good job with the infomercial though, I've seen it playing for years now.😛
 
In modern fuel injected cars? No.

In an older, poorly designed, carbureted engine? Maybe.
 
I got one as a gift and RMA'd it. They stiffed me on the refund and never even responded to emails. That didn't stop them from continuing to spam me (who never bought from them & whose only contact was the RMA) with special offers for other, similarly amazing products.

I would reccommend just burning your cash or giving it to a wino before buying from them-just my opinion and experience.

Wonder if its a Type-R too! ??!!

What a bunch of BS. They should get thrown in jail just on principle, let alone blatently false advertising!
 
From what I understand, after hearing a report on the radio (I think it was Car Talk), they really do work; but only because people change their driving habits (either consciously or unconsciously) which in turn increases their mpg.

In all actually they could increase their mileage by changing their driving habits, like pressing the accelerator like there is an egg between your foot and the pedal. Or driving at 65 mph instead of 75.

Sort of like taking plecebos for an illness.

Also keeping your tires at the high end of the recommended pressure range can significantly reduce rolling resistance and improve mpg. Probably will do more than the tornado or magnetic resonator.

A dirty fuel filter will not make your engine work harder, what can happen though is that if you do not change your filter and it does become plugged and restricts the fuel, your ECM will try to compensate for the lean mixture and increase injector opening times, thus resulting in less fuel economy,(less accuracy in fuel management) hesitation and if it continues, catalytic converter damage.
