Filling up at the gas station should be simple—pull up, select your fuel type, and start pumping. But what if you accidentally choose the wrong gas? Whether it’s putting regular in a car that requires premium or mistakenly filling up with diesel, the wrong fuel can lead to anything from mild performance issues to severe engine damage. If you’ve ever found yourself wondering what happens when the wrong gas goes into your vehicle, understanding the risks and knowing what to do next can save you from costly repairs. Using Regular Gas in a Car That Requires Premium Many performance and luxury vehicles require premium fuel (usually 91 or 93 octane) because their engines are designed for higher compression ratios. If you accidentally use regular unleaded (87 octane) in one of these cars, it might not cause immediate damage, but it can lead to reduced performance, knocking sounds, and long-term wear on the engine. Modern vehicles have knock sensors that ... read more

Turbocharged engines are known for their power and efficiency, while naturally aspirated engines are praised for their reliability and linear performance. But which one is right for you? Turbocharged Engines Turbocharged engines use a turbine driven by exhaust gases to compress more air into the combustion chamber. This allows the engine to burn more fuel and produce more power without increasing its size. The result? Smaller engines with the performance of larger ones. One major advantage of turbo engines is their ability to deliver impressive power output and acceleration, especially at lower RPMs. This makes them popular in performance-focused vehicles and modern every ... read more
