Does anyone know the following info?

MPG City?
MPG Hwy?
Range?
gallons of fuel left when light comes on the dash?

and also if you could share how you feel i could improve my fuel economy..

This may sound stupid, but i saw a commercial for one of those Tornado Air Intake Gizmos,, they look like a joke but was wondering if anyone had used or heard of how these work and if they really do make a difference..

Evan:

Fix the leaking head gasket first. Worry about gas mileage later.

They are a joke. And they do make a difference. -They restrict the airflow to your engine. -Not desireable!

My300E is a manunal trans, so is probably not indicative for most of the rest of you. It gets 27 to 28 on the highway and around 20 stoplight to stoplight. There is about a gallon or a little more when the reserve light comes on and it has about a 17.5 gallon tank I think.

The cyclone gizmo on SOME carbureted engines could in rare instances improve, probably immeasurably, fuel mileage. This is because in a carbureted engine the fuel is mixed with the air and sometimes does not atomize properly. This means that the fuel sometimes flows in droplets rather than a mist. In some cases this gizmo could mix the fuel causing more complete combustion.

In a fuel injected engine, the air flows by itself until the very end of the intake runner where the fuel is injected as a mist in the airstream. In this case, which covers most all cars built in the last fifteen years or so, the cyclone does just as Freestyler says, they only inhibit air flow.

They are snake oil and the folks who sell them should be ashamed of themselves.

Have a great day,

The "swirling" effect that they tout occurs too soon in the combustion cycle to do any good. It is pointless to "swirl the air" at the airbox.

For any possible (but negligible gain) in performance, the swirling must occur at the intake chambers, where the fuel and air mix.

Some performance-oriented folks spend $$ to have their intakes "swirl-ported" to enhance air flow...but as Larry stated, this enhances carb'ed engines only where the fuel and air mix occurs at the intake runners.

Don't bother getting one...if you do, stick it in your lawn mower chute for more efficient swirl mulching!

Fuel injection engines normally have turbulent airflow mainfolds -- there is absolutely no point in maintaining laminar flow to suspend the fuel droplets (aka mist) since the fuel is introduced right at the intake valve while it is open.

Carbs, on the other hand, REQUIRE laminar flow as much as possible to get the fuel mix at the cylinder correct -- turbulence or flow direction changes cause the fuel to drop out (it's much heavier) and decrease efficiency considerably.

You won't gain anything by porting and polishing a Benz -- they don't just slap a bunch of pipes on like Detroit did in the 50 and 60s, and Detroit does a decent job these days too.

Cyclone devices in the air horn are simply nonsense, on a par with "magentic fuel enhancers".

Milage on the TE is about 19 around town, 22-24 on the highway, never better. A sedan should run more like 26 on the highway if you drive gently.

Lots of pedal will make a difference....

I used one of those Tornado Air Intake Gizmos in my car and now my gas mileage is so high that I have to go back to the gas station once a month to RETURN gas

Are you serious,, did you see a big increase in mileage right away, and could this sudden boost in economy be a result of something else you did within this time frame?

I put one in my Honda and the air went in so fast it blew one of the pistons to the bottom of the cylinder and pushed the rest of them up to the top!! This happened over and over until it finally sucked all the gasoline out of the tank! Man I'm glad that's over!!

That's what I'm afraid of, gasoline forcing its way back through the filler neck and down the side of the fender is a safety hazard, not to mention that it will act as a solvent and dissolve the wax.

Have a great day,

What I can't figure out is how it took gas and forced it through the motor and it came out of the tailpipe as a mixture of gas????
