Egypt: Egyptian fuel stations had 90 RON until July 2014 when the government found no remaining use for it, leaving only 92 RON and 95 RON. 80 RON is found in a very limited number of fuel stations as they are used only for extremely old cars that cannot cope with high octane fuel. 95 RON was used limitedly due to its high price (more than ...
In the United States and Canada, octane ratings are in AKI, commonly shown as "(R+M)/2". All states require gas pumps to be labeled with the correct octane level and nearly all states do regular testing to make sure gas stations are in compliance. A minimum 82 octane fuel is recommended for most vehicles produced since 1984.
The fuel-characteristics of a particular gasoline-blend, which will resist igniting too early are measured as the octane rating of the fuel blend. Gasoline blends with stable octane ratings are produced in several fuel-grades for various types of motors. A low octane rated fuel may cause engine knocking and reduced efficiency in reciprocating ...
In addition to filling stations, numerous suppliers of industrial gas run dedicated autogas stations on their premises. Most filling pumps use the ACME adapter but DISH can also be found. Special fuel tax rates make autogas rather cheap in Germany (about €0.52 per litre while 95-octane unleaded is €1.40 per litre).
The Environmental Protection Agency (EPA) requires the registration of all fuel additives which are commercially distributed for use in highway motor vehicles in the United States, [8] and may require testing and ban harmful additives. The EPA also regularly reviews the health and net economic benefits of Clean Air Act policies. [9]
According to the Energy Information Administration (EIA), as of March 2022, factors that affect the price of gasoline in the United States include the price of crude oil per barrel, costs and profits related to refining, distribution, and marketing, and taxes, along with the charge set by refiners for gasoline based on based on octane levels, with higher octane levels—premium grade cost ...
It was widely used as a fuel additive for much of the 20th century, first being mixed with gasoline beginning in the 1920s. This "leaded gasoline" had an increased octane rating that allowed engine compression to be raised substantially and in turn increased vehicle performance and fuel economy.
A fuel tax (also known as a petrol, gasoline or gas tax, or as a fuel duty) is an excise tax imposed on the sale of fuel. In most countries the fuel tax is imposed on fuels which are intended for transportation. Fuel tax receipts are often dedicated or hypothecated to transportation projects, in which case the fuel tax can be considered a user ...
