Can Different Types of Gasoline Be Mixed in a Car?
1 Answers
Gasoline can be mixed, but it is not recommended. Here are the criteria for selecting gasoline: 1. Choose gasoline according to the car manufacturer's specifications: Selecting gasoline based on the manufacturer's guidelines is the most common method. The vehicle's user manual usually provides clear instructions. 2. Choose gasoline based on the engine's compression ratio: The general principle for gasoline usage is: engines with a compression ratio of 7.0 to 8.0 should use 90-octane gasoline; engines with a compression ratio above 8.0 should use 93-octane or 97-octane gasoline.
