Gas prices are up, and so is the degree of advertising for “gas-saving” products. When gasoline costs rise, consumers usually search for ways to enhance fuel efficiency. Though there are practical steps you’ll take to increase gas mileage, the Federal Trade Commission (FTC) warns you to be wary of any gas-saving claims for automotive devices or oil and gas additives. Even for the few gas-saving product that have been found to figure, the savings are small.
“Gas-Saving” Advertising Claims
Be skeptical of the subsequent types of advertising claims.
“This gas-saving product improves fuel economy by twenty percent.”
Claims sometimes tout savings ranging from 12 to twenty five percent. However, the Environmental Protection Agency (EPA) has evaluated or tested a lot of than one hundred alleged gas-saving devices and has not found any product that considerably improves gas mileage. In fact, some “gas-saving” products could harm a automobile’s engine or cause substantial will increase in exhaust emissions.
The gas-saving merchandise on the market fall into clearly outlined categories. Although the EPA has not tested or evaluated each product, it’s tried to look at a minimum of one product in each category. See “Devices Tested by EPA” at the end of this brochure for class descriptions and products names.
“Once installing your product on my automotive, I got an further four miles [6.4 kilometers] per gallon [3.8 liters].”
Many ads feature glowing testimonials by satisfied customers. Yet, few customers have the ability or the equipment to check for precise changes in gas mileage when putting in a gas-saving product. Many variables affect fuel consumption, as well as traffic, road and weather, and also the automotive’s condition.
For example, one shopper sent a letter to an organization praising its “gas-saving” product. At the time the merchandise was put in, however, the consumer also had received a complete engine tune-up – a truth not mentioned within the letter. The whole increase in gas mileage attributed to the “gas-saving” product could well are the result of the tune-up alone. But from the ad, alternative customers may not have known that.
“This gas-saving device is approved by the Federal government.”
No government agency endorses gas-saving product for cars. The most which will be claimed in advertising is that the EPA has reached certain conclusions about potential gas savings by testing the product or by evaluating the manufacturer’s own test data. If the seller claims that its product has been evaluated by the EPA, ask for a replica of the EPA report, or check http://www.epa.gov for information. In some instances, false claims of EPA testing or approval are made.
Product Complaints and Refunds
If you are dissatisfied with a gas-saving product, contact the manufacturer and raise for a refund. Most companies provide money-back guarantees. Contact the company, whether or not the guarantee period has expired.
If you’re not satisfied with the corporate’s response, contact your native or state consumer protection agency or the Better Business Bureau.
EPA Analysis Efforts
The EPA evaluates or tests product to work out whether their use will lead to any significant improvement or detriment to fuel economy. But, the EPA cannot say what effect gas-saving merchandise can have on a vehicle over time as a result of it hasn’t conducted any durability tests. It’s doable that some merchandise may hurt the car or could otherwise adversely have an effect on its performance. After all, nowadays’s vehicles’ emission control systems are very refined and complex. They have On Board Diagnostic options that alert the motive force to problems related to the emission management and fuel delivery systems. Retrofit product might have an adverse impact on these systems.
Devices Tested by EPA
The following list categorizes various types of “gas-saving” merchandise, explains how they are used and offers product names. Those with asterisks could save measurable, but little, amounts of gas. All others are found not to extend fuel economy.
