It is safe to fill a carbureted car that normally takes 87 AKI fuel at sea level with 85 AKI fuel in the mountains, but at sea level the fuel may cause damage to the engine. However, since virtually all cars produced since the 1990s have fuel injection , 85 AKI fuel is not recommended for modern automobiles and may cause damage to the engine and decreased performance.
