Can I use regular gas in a car that requires premium?
While you can use regular gas in a car that recommends premium, it may lead to reduced engine performance and efficiency. Vehicles designed for premium fuel often have higher compression ratios, requiring fuel that burns at a slower rate and resists pre-ignition, also known as knocking. Regular gas has a faster burn rate and lower octane rating, which can cause engine knocking or pinging in high-compression engines. This knocking can damage engine components over time. It’s best to follow the manufacturer’s recommendation to ensure optimal performance, fuel efficiency, and longevity of your vehicle.
