Another Fuel Saver

Vehicle fully tuned up and serviced. Ran on dynamometer and got 9.4 MPG. Added the new gismo and got 23.2 MPG. Ran it around for a month and then on the road it got 16.1 MPG.

Cost is about $1200.00, so they say.

If I put two on my truck, would I get 32.2 MPG??
It must be true----they said so on TV!!!!

They put a toyota or something like that on a chassis dyno started it up and ran it showing fuel consumption, power etc. Then they put the doo-hickey on there in about 10 minutes and ran again showing mileage increase etc.

Well what happened is when they ran it the first time, the motor was cold and was running on the cold start cycle, running richer. After test 1 and the soak time while they installed the doo-hickey, the car was warmed up enough to run in the normal warmed up cycle. So of course it used less fuel. They don't tell you that in the ad but they busted them on this show!

I've seen people do basically the same thing vis-a vi a race engine on a dyno by not duplicating all factors (temps, air density, oil temp, etc.) during a dyno run. You can sure be misled.

From the article: "...in any engine, roughly 15% of the gas isn't burned; instead its pushed out through your exhaust pipe." That alone is enough to tell you whoever wrote the article has no mechanical background. If that was a true statement, there are no cars on the road that will pass a smog test. Not to mention they don't explain how recovering this supposed 15 percent wasted fuel is supposed to double the gas mileage.

Here's a link to the article.

Yeah it does accually, it just burns up the rest of the gas in the exhaust pipe :-)

When rally cars spool up injector dumps raw gas into the exhaust to keep the turbo spinning, they might be getting close to the 15% mark. Or dragsters with way aggressive cams idling, they dump massive quantities of fuel. But not your everyday car. Unless you pull a spark plug wire.
