British motorists are being urged to steer clear of a potentially damaging 'fuel-saving' gadget that is being heavily promoted online. The device, which promises to slash fuel costs, has been labelled a dangerous gimmick by leading automotive experts.
The Deceptive Promise of Better Fuel Economy
Amid the ongoing cost-of-living crisis and high fuel prices, drivers are increasingly searching for ways to improve their vehicle's efficiency. This has created a fertile ground for unscrupulous sellers marketing a small, magnetic device that claims to restructure fuel molecules for better combustion and improved miles per gallon.
However, the reality is far less promising. The RAC has issued a stark warning, stating that not only do these devices fail to work, but they could also lead to serious and expensive engine damage.
Why This Gadget Is a Threat to Your Engine
The gadget is typically installed onto a car's fuel line. The major risk, as highlighted by the RAC's fuel spokesman Simon Williams, is that the device can easily come loose. If this happens, it can cause a dangerous fuel leak, creating a severe fire hazard and potentially leading to a catastrophic engine failure.
Williams bluntly advised drivers to "avoid them like the plague", emphasising that they are a complete waste of money and pose a significant safety risk. There is no independent evidence to support the extravagant claims made by the manufacturers.
The Real Culprit: E10 Petrol and Its Effects
The promotion of these gadgets often preys on motorists' genuine concerns about E10 petrol. Since its introduction as the standard grade in the UK, some drivers have reported a slight reduction in fuel economy. Fraudulent sellers exploit this by claiming their product can counteract these effects.
The legitimate solution for drivers experiencing issues with E10 is not a magnetic gadget, but simply to use the higher-octane E5 petrol, available at most forecourts, if their vehicle is compatible.
How to Actually Improve Your Fuel Efficiency
Instead of falling for online scams, drivers seeking better fuel economy should focus on proven methods:
- Check your tyre pressures regularly: Under-inflated tyres increase rolling resistance and fuel consumption.
- Reduce vehicle weight: Empty your boot of unnecessary heavy items.
- Drive smoothly: Avoid harsh acceleration and heavy braking.
- Use higher gears early: Where safe, change up a gear sooner to keep revs lower.
- Limit air conditioning use: Use it sparingly as it increases engine load.
The message from experts is clear: if a fuel-saving solution seems too good to be true, it almost certainly is. Investing in proper vehicle maintenance and adopting efficient driving habits remain the only reliable ways to save money at the pump.
