How to Use Regular Fuel in a BMW 325
1. Fill the tank with high-test 91+ octane gasoline when it is almost empty. This will help the engine run well, and clean out any carbon buildup.
2. Run the vehicle to half a tank, then fill with 87-octane fuel. This will give you mid-grade fuel of 89. The BMW engine is rated for 91-octane fuel.
3. Run the car till it needs fuel again and fill with 89-octane. At the next fuel stop, repeat the process starting with high-test fuel. This cycle will allow you to run regular fuel in the BMW 325.
