Actually the higher the octane level the poorer the gas mileage. This is because the higher octane fuel burns slower and less efficiently for that particular engine.
I agree 100%. The oil companies use the term Super or Premium to entice you to buy the higher octane fuel. It is a myth that it provides better mileage or more power. Use exactly what your engine was designed to run on.
