93 is widely available in the Chicago area. Elsewhere in Illinois, 93 is offered at Shell and select other stations. Many fuel stations now offer an 88-octane fuel blend that is 15% ethanol, suitable for use in some gasoline-powered automobiles from model year 2001 and newer. Indiana: 87 89 93 Iowa: 87 89 91
An Audi R10 TDI LMP race car, fueled on Shell V-Power Diesel. V-Power Diesel is Shell's version of an enhanced diesel fuel, similar to BP's 'Ultimate Diesel'. Like BP Ultimate Diesel, Shell V-Power Diesel is designed for modern compression-ignition diesel engines, to facilitate enhanced engine performance along with increased engine protection, for more consistent operation and engine longevity.
Shell V-Power is also available, but in a 99 RON octane rating, and Tesco fuel stations also supply the Greenergy produced 99 RON "Momentum 99 ". United States: in the US octane rating is displayed in AKI. In most areas, the standard grades are 87, 89–90, and 91–94 AKI.
Octane rating is measured relative to a mixture of 2,2,4-trimethylpentane (an isomer of octane) and n-heptane. There are different conventions for expressing octane ratings, so the same physical fuel may have several different octane ratings based on the measure used. One of the best known is the research octane number (RON).
The Shell Martinez Refinery in Martinez, California, the first Shell refinery in the United States, supplied Shell and Texaco stations in the West and Midwest [12] until its sale to PBF Energy in 2020. [13] Shell fuel previously included the RU2000 and SU2000 lines (later there was a SU2000E) but they have been superseded by the V-Power line. [14]
The repair for this type of problem depends on the severity of the deposits. In milder cases, a mechanic may solve the problem by adding a can of fuel-injector cleaner into the gas tank. However, in some cases, the fuel injectors must be replaced. Deposits formed on the intake valves may be removed via walnut shell blasting.
Picture showing E0 100% gasoline at $1/gallon more than E10 Regular Unleaded. At this same Saugatuck, MI Shell station, E85 was an additional $1/gallon below regular ($2/gallon below ethanol-free Rec-90). As debate has ensued over ethanol blending in gasolines, ethanol-free has popped up in a number of states marketed as Rec-90 Recreational ...
2,2,4-Trimethylpentane, also known as isooctane, is an octane isomer which defines the 100 point on the octane rating scale (the zero point is n-heptane). It is an important component of gasoline. Isooctane is produced on a massive scale in the petroleum industry, usually as a mixture with related
