**Testing Fuel Saving Gadgets: A Scientific Approach**

To determine if fuel saving gadgets are truly effective, it's essential to conduct thorough and scientific tests. In this study, we aimed to find out if these devices can genuinely reduce fuel consumption and emissions. We visited the University of Hartford's shared automotive engineering department, where we set up a 40,000-pound rolling road to ensure that all tests were conducted in identical conditions.

**The Setup**

Using the specialized equipment, including an ECU worth around $5,000 and dedicated fuel monitoring software costing $1,500, engineer Gareth was able to measure the exact amount of petrol consumed by the car during a 20-minute run at varying speeds. The Vauxhall Insignia was found to consume 49 miles per gallon over this period. With this setup, we were able to test each gadget in the same way and see if they worked as claimed.

**The EMAG: A Powerful Magnet**

The first gadget we tested was the EMAG, a powerful magnet that claims to reduce fuel consumption by up to 15% and decrease carbon emissions while increasing performance. The device allegedly breaks down fuel molecules to achieve a more efficient mix of fuel and oxygen. We attached it around the fuel line and began driving the car. After an identical 20-minute drive, we obtained results of 47.72 miles per gallon. This was less than the original baseline of 49 miles per gallon.

**The EMAG's Claim**

It's essential to note that the makers claim that benefits will only be seen after 2,000 miles. We tested the EMAG in the cigarette lighter socket for a mere 20 minutes, which is unlikely to yield significant results. In this test, the EMAG did nothing to improve fuel efficiency.

**The VIBRIO: A Device with a Claim of Stabilizing the Car's Electrical System**

Next up was the VIBRIO, a device that claims to save up to 10% in fuel by stabilizing the car's electrical system. It's plugged directly into the cigarette lighter or 12-volt electrical socket. We spent 20 minutes with this device and obtained results of 47.06 miles per gallon. This was less than the original baseline, indicating that the VIBRIO also failed to provide any benefits.

**The ECU: A Metal Box with a Claim of Increasing Explosive Force**

Our next gadget was the ECU (Electronic Matching Unit), which costs $1,500 and claims to save up to 10% in fuel. It allegedly increases the explosive force in your cylinders, helping it burn more efficiently. After testing this device for 20 minutes, we obtained results of 47.46 miles per gallon.

**The MagnaFlow: A Magnetic Field that Conditions Fuel**

The MagnaFlow was another gadget with a claim that its magnetic field conditions the fuel before entering the engine, resulting in better combustion efficiency and saving up to 23% on fuel consumption. We tested this device for 20 minutes and obtained results of 48.05 miles per gallon.

**The Briquette: A Device from World War Two**

Our final gadget was the Briquette, a pellet-based catalyst that reacts with fuel to improve combustion efficiency. This device is designed to save between 7-10% on fuel consumption and has been used since World War II. We tested this device in the fuel line for 20 minutes and obtained results of 48.36 miles per gallon.

**Expert Analysis**

Dr. Rashid Ali, an expert in electronics from the University of Hartford, examined the internal components of some of these gadgets. He was shocked by the quality of soldering on some devices, stating that most electronic printed circuit boards should be electrochemically cleaned to prevent second contacts between pads and components. Dr. Ali also expressed disappointment with how an LED is connected using hot glue.

**Conclusion**

Based on our findings, we cannot recommend any fuel-saving gadgets at all. The EMAG, VIBRIO, ECU, MagnaFlow, and Briquette failed to provide any significant benefits in reducing fuel consumption or emissions during our tests. We urge consumers to be cautious when considering these devices and to seek scientific testing before investing their hard-earned money.
