FIVE COSTLY DRIVING MYTHS

Basically, there are two things that make every car owner go nuts: higher gasoline prices and higher maintenance fees. They find ways to lower such costs by placing different cost-saving methods. However, not all budget-friendly driving tips are effective. Find out why.

Airflow Gadgets Improve Fuel Efficiency

It sounds reasonable, but results do not support such claims. Consumer Reports tested different devices. One of the gadgets tested is Fuel Genie, which purports 50% fuel savings. Tests found no remarkable gains in MPGs. It is true escalating the airflow to an engine is one way of boosting horsepower. But in reality, it will increase fuel consumption and wear on the engine, not to mention this is more expensive than its alternatives.

Add Formulated Chemical to Gas to Amplify Fuel Efficiency

...and sometimes, horsepower. How drivers wish there is a magic elixir (of some sort) to solve their fuel worries. No scientific explanation or evidence proves numerous oil treatments can increase MPGs. A CNN.com report even disclosed one of the common tactics used by sham fuel additive makers is creating a bogus Environmental Protection Agency (EPA) approval. But EPA tells us otherwise. Oil firms would scramble to market these additives and attain a larger market share. Also, the product does not increase a vehicle’s harmful emissions.

Using Aircon instead of Rolling Down Windows to Cool the Car

In certain cases, some fuel is used to power the AC compressor. But more fuel is lost when the windows are down as it amplifies the drag on the car, causing the vehicle to work double time to retain its speed. Instead of forcing the aircon to cool the temperature from outside, a car owner can improve the aircon effectivity by using recirculation setting on the vehicle’s HVAC system to maximize mileage and enhance comfort.

Premium Gas = Better Performance, Gas Mileage

This is true, if and only if, you own a premium car requiring high octane gas. Most cars have engine control unit designed to operate on a normal gasoline’s octane level. So, if you decide on raising the octane level of your vehicle, it can make the engine less efficient since the car’s combustion timing is modified, losing its capacity. Not only that, you will also lose additional 20 cents a gallon for obtaining high-octane fuel. It is safe to say you won’t be concerned with oil prices or trailing mileage if you can afford to purchase a vehicle that uses only premium gas.

Rounder Tires Guarantee Easier Movements

But to a particular point. Yes, over-inflated tires create less work for the engine and will have less friction, resulting to a better MPG. This is definitely a cost-saving tip. But over-inflated tires will wear out swiftly and irregularly. Hence, you need to replace the tires every time, which amounts to around $50 to $100 per tire. And to make things worse, the lower contact with the road raises stopping distance and constricts handling abilities, plus the potential accidents and injuries. Use the recommended settings and levels for best results.
