"Premium 91" (RON 91) has green pumps, and "Super Premium 95" (RON 95) where the pumps are red. The balanced chemical equation for the complete combustion of octane is: The net result is that to make a given amount of power, more high-octane fuel must be burned in the engine. .css-1o5pw2t{width:24px;height:24px;display:inline-block;vertical-align:middle;position:relative;overflow:hidden;top:-0.1em;fill:rgba(187,186,192,1);}.css-1o5pw2t::before{position:absolute;display:block;left:0;}.css-1o5pw2t::after{content:'';display:block;position:absolute;left:0;right:0;top:0;bottom:0;}.css-1o5pw2t svg{position:absolute;width:100%;height:100%;fill:inherit;display:block;left:0;top:0;right:0;bottom:0;}.css-1o5pw2t:hover,.css-1o5pw2t:focus{fill:rgba(117,114,128,1);}. Latvia: 95 RON and 98 RON widely available. issued pricing for Super.

It's now been another month and half . Higher-octane, lower-energy-dense "thinner" fuels often contain alcohol compounds incompatible with the stock fuel system components, which also makes them hygroscopic. 2B, Oct. 2000, pp. Also available Super LRP 96 RON for older (non-catalytic) vehicles.

96 RON is also available at a large number of gas stations but 95 RON is more preferred because it's cheaper and performance differences aren't very wide and noticeable. HOBC pricing was deregulated in October, 2016. Unfortunately, the side effects of adding lead to gasoline are: Lead clogs a catalytic converter and renders it inoperable within minutes. Math. Iran: 87 RON (marketed as regular) and 95 RON (marketed as Super) are widely available in gas stations. The compression ratio of your engine determines the octane rating of the gas you must use in the car. Eighty-seven-octane gasoline is gasoline that contains 87-percent octane and 13-percent heptane (or some other combination of fuels that has the same performance of the 87/13 combination of octane/heptane). See the table in the following section for a comparison. Thailand: 95 RON is widely available. apply for financing! The disadvantage is that the gasoline for your engine costs more. The selection of octane ratings available at filling stations can vary greatly between countries. [5][unreliable source? Werner Dabelstein, Arno Reglitzky, Andrea Schütze and Klaus Reders "Automotive Fuels" in Ullmann's Encyclopedia of Industrial Chemistry 2007, Wiley-VCH, Weinheim. This organic molecule is a colourless liquid at room temperature with a characteristic "gasoline" odour. Pilots are taught in primary training to avoid settings that produce the highest exhaust gas temperatures, and run the engine either "rich of peak" (more fuel than can be burned with the available air) or "lean of peak" (less fuel, leaving some oxygen in the exhaust) as either will keep the fuel-air mixture from detonating prematurely. 92, HOBC 95 & HOBC 97 RON. Spain: 95 RON "Euro" is sold in every station with 98 RON "Super" being offered in most stations. It is possible for a fuel to have a Research Octane Number (RON) more than 100, because iso-octane is not the most knock-resistant substance available.

Octane is a hydrocarbon and an alkane with the chemical formula C 8 H 18, and the condensed structural formula CH 3 (CH 2) 6 CH 3.Octane has many structural isomers that differ by the amount and location of branching in the carbon chain. Poland: Eurosuper 95 (RON 95) is sold in every gas station. I was told the worst news. Costa Rica: RECOPE, Costa Rica's distribution monopoly, establishes the following ratings: Plus 91 (at least 91 RON) and Super (at least 95 RON). How long will the footprints on the moon last? "Extra" is the most commonly used. Cheaper grades of gasoline could be made usable by adding TEL. I asked if I should make a deposit as I was intending to buy it in any case and the sales person/owner said I wouldn't need to and can come in on the Monday to make a deposit, and pick up the car on Tuesday.I called in on Monday and he told me he sold the car. In most countries in Europe (also in Australia, Pakistan and New Zealand) the "headline" octane rating shown on the pump is the RON, but in Canada, the United States, Brazil, and some other countries, the headline number is the simple mean or average of the RON and the MON, called the Anti-Knock Index (AKI), and often written on pumps as (R+M)/2. Two variants, "Speed 93" and "Speed 97", were launched, with RON values of 93 and 97. 98 and 100 RON (Shell V-Power Racing) has been dropped in late 2009. On January 1, 2018, Vietnamese government forced every gas station stop selling 92 and sell 95 + A92-E5 instead. [9], The RON/MON values of n-heptane and iso-octane are exactly 0 and 100, respectively, by the definition of octane rating. Italy: 95 RON is the only compulsory gasoline offered (. Sri Lanka: In Ceypetco filling stations, 92 RON is the regular automotive fuel and 95 RON is called 'Super Petrol'. Taiwan: 92 RON, 95 RON and 98 RON are widely available at gas stations in Taiwan.

If you are using 87 octane, you might be spending less at the pump, but your spark plugs are not firing evenly with the gas you are using. Racing fuels, avgas, LPG and alcohol fuels such as methanol may have octane ratings of 110 or significantly higher. Octane ratings are not indicators of the energy content of fuels.

With their reduced densities and weight per volume of fuel, the other obvious benefit is that an aircraft with any given volume of fuel in the tanks is automatically lighter.
