Gasoline

On the price and use section, there's not enough information in the Europe paragraph, for example, some charts can be provided to illustrate the difference between the price of oil in the USA and Europe, or a chart to prove the difference in tax between the USA and Europe. In the USA paragraph, "Cars with turbocharged engines and high compression ratios often specify premium gas because higher octane fuels reduce the incidence of "knock", or fuel pre-detonation. [140] The price of gas varies considerably between the summer and winter months "The content needs to be adjusted, because it is not only turbocharged machines that have high compression ratios, but some naturally aspirated or supercharged machines have high compression ratios. In addition, this content should be moved to the Octane section, which is more appropriate.
