chosen: It depends on your car and the local environmental conditions. Check your owner’s manual to see what type of gas your car requires, or talk to your mechanic for advice. Generally, higher-end vehicles with better fuel injection and engines will require premium gas, as it contains additional layers of detergent to help keep the engine clean and reduce polluting and wear-and-tear. In many cases, it’s also better for fuel economy. For regular cars, regular gas is just fine.
