It’s been a thing. My car is 20 years old and requires it. Engines with higher compression require higher octane fuel to reduce pre-detonation and pinging. Using low-octane fuel in one of them can cause game-ending physical damage to the engine. Many more modern cars can sense lower-octane fuel and adjust for it, at the cost of power and efficiency (i.e., mileage). |
