★ Top Answer
Your 2007 BMW X3 is meant to be fueled with 91 octane gasoline. While it is possible to use 87 octane fuel, it is not advised as it may lead to engine knock and potential damage over time. When using a lower octane fuel than recommended, the car's ECU can compensate for the difference and make adjustments. However, this might result in reduced horsepower and lower fuel efficiency, while increasing CO2 emissions. The vehicle has a fuel tank capacity of 17.7 gallons, with a city fuel efficiency of 18 mpg and a highway efficiency of 26 mpg.
