Many drivers are constantly looking for ways to improve their car’s fuel economy. With rising gas prices, the appeal of aftermarket devices promising to boost mileage is stronger than ever. Among these, OBD2 fuel savers have gained attention, claiming to optimize engine performance and reduce fuel consumption simply by plugging into your car’s OBD2 port. But do these gadgets actually live up to the hype, or are they just another automotive myth? Let’s delve into the reality behind OBD2 fuel savers and similar fuel-saving devices.
One such product that exemplifies the claims and, more importantly, the lack of results often seen with these types of devices is the Platinum Gas Saver. Marketed with bold promises, the Platinum Gas Saver claimed to increase fuel mileage by an impressive 22 percent and even extend engine life by cleaning carbon deposits. This device, consisting of tubing and a reservoir with a platinum-infused liquid, was designed to connect to a vacuum line leading to the intake manifold. The manufacturer asserted that by introducing microscopic amounts of platinum into the air and fuel mixture, the engine would burn gasoline more efficiently and cleanly.
To put these claims to the test, rigorous evaluations were conducted on two different vehicles: a Nissan Altima and a Ford Excursion. Following the manufacturer’s installation instructions, researchers performed standard acceleration and fuel economy tests both with and without the Platinum Gas Saver installed. The manufacturer suggested that the device might require a break-in period of 200 to 1,800 miles to become fully effective. They also hinted at the possibility of needing to advance engine timing by 10 to 12 degrees or install new oxygen sensors for optimal results. However, it’s crucial to note that adjusting engine timing or replacing oxygen sensors, if they were indeed faulty, could independently improve fuel economy, regardless of the Platinum Gas Saver.
Despite diligently testing the device over 500 miles in each vehicle, no discernible improvements in fuel economy were observed. Going the extra mile, researchers even replaced the oxygen sensors in both test cars, despite them being new and functioning correctly. This step was taken to eliminate any potential influence from oxygen sensor performance, as suggested by the manufacturer. Furthermore, attempts to advance the engine timing were thwarted by the vehicles’ modern computer-controlled electronic ignition systems. These systems are designed to maintain optimal fuel economy and emissions standards automatically, preventing manual timing adjustments. In the end, after more than 1,800 miles of driving across both test vehicles, the Platinum Gas Saver failed to demonstrate any measurable increase in fuel mileage.
Beyond the ineffectiveness of the device itself, the potential costs associated with achieving the manufacturer’s suggested “optimal performance” raise further concerns. Consumers would not only have to purchase the Platinum Gas Saver but might also be pressured into replacing oxygen sensors, incurring an additional expense of around $140 per vehicle for the sensors alone, plus labor costs for installation.
The findings from testing the Platinum Gas Saver strongly suggest a broader truth about many aftermarket fuel-saving devices, including OBD2 fuel savers. While the allure of a simple plug-and-play gadget that dramatically improves gas mileage is undeniable, the reality often falls far short of these promises. Modern vehicles are already engineered for optimal fuel efficiency by their manufacturers. Significant gains from simple aftermarket modifications are generally not achievable and can sometimes even be detrimental.
Instead of relying on unproven devices, the most effective way to maximize your fuel economy is to adhere to your vehicle manufacturer’s recommended maintenance schedule. Regular servicing ensures your engine is running efficiently. Furthermore, adopting fuel-conscious driving habits, such as smooth acceleration, maintaining steady speeds, and avoiding unnecessary idling, can make a tangible difference at the pump.
In conclusion, while the idea of OBD2 fuel savers and similar devices is tempting, evidence and testing, like that conducted on the Platinum Gas Saver, indicate they are unlikely to deliver on their promises of significant fuel savings. Focusing on proper vehicle maintenance and mindful driving habits remains the most reliable path to achieving better fuel economy.
