It depends on which car you are talking about. I don't know specifically what cars will benefit. But from my personal experience with the Tornado (basically the same thing as the Turbonator), i gained only a couple mpg on my 85 Monte Carlo ss and gain nothing on my 04 Dodge neon. your best bet is to look up the tornado on eBay and find one cheap if you want to try it out. if it doesnt work, take it out and throw it back on eBay.
Answeronly in theory. it poses as a restriction to airflow. the less air the engine is getting the less fuel it needs.Turbonator, Tornado, Cyclone, or whatever they are called, simply do not work. They do not increase H.P. nor Mileage. In fact they may hurt both. The Turbonator makes this claim and I quote. "More Power: Are you looking for more power from your wheels? Whether you have a stock or aftermarket intake system, the Turbonator can add up to 35 horsepower to your vehicle.* Fuel Savings : Turbonator users have reported MPG increases from 10 to 22 percent. Results will vary depending on your driving habits and the condition of your vehicle". These claims alone should send you running. A 22 percent increase in MPG on a car already getting 25 would be 5.5 MPG. Also a claim of an increase of 35 H.P. is ridiculous. The swirl effect they claim to create is already there with a stock system. There is no magic device to increase H.P. except a computer tuning chip. They will increase H.P. but usually at the expense of Mileage. Things like headers, dual exhaust, will give you a slight increase but at a high cost.
Yes, higher octane gas does give higher gas mileage for your car. However, the increase in gas mileage may not as great as the increase in the price of the higher octane gas.
No, it will decrease gas mileage.
Spoilers decrease gas mileage. Spoilers are designed to create down force, which creates drag. The drag will increase gas usage.
There are some practical ways to increase the gas mileage but you can use also Fuel Infusion what is a powerful fuel catalyst. Fuel Catalyst realy helps to increase to boost your engine power and your gas mileage.
False
No it will not give you better performance or increase gas mileage. Gas mileage and performance will decrease only if you use it. leaving it off is like not having it at all.
yes
Not unless the engine using it was specifically designed for it. Gas mileage takes many things into consideration, and if a car is designed to use standard octane gas, the use of high octane gas will not increase the car's mileage - it is just a way of figuratively blowing dollar bills out of the tailpipe.
depending on your driving, it could increase up to 4 or 5 mpg. But gas mileage will be determined by driving style.
No, friction decreases gas mileage. If you are talking about Friction motor treatment then it is just another in a long line of products claiming to increase mileage. None of them work, period.
You'll want to look for a performance air filter. Basically these increase gas mileage by increasing air supply. The more air which is available and circulating, the better the overall gas mileage.
