What octane gas is best to use for a two stroke outboard motor. January 6th, 2012, 12:12 PM. Re: What octane gas is best to use for a two stroke outboard motor. If you're looking for solvents in the higher octane fuels to clean out the fuel system, the ethanol itself is a great solvent to loosen up crud in the fuel system.

What Octane Gas to Use In the United States, Federal law requires that gasoline octane ratings be posted on the pumps. The octane rating shown is an average of Research (R) octane number and Motor (M) octane number. You should use unleaded gasoline with an octane rating of at least 87. Using Unleaded gasoline with an octane rating lower than the stated above can cause persistent, heavy 'spark knock' ('spark knock' is a metallic rapping noise). If severe, this can lead to engine damage.

Is it bad for my Toyota Prius if I fill it up with racing fuel? I think the European Prius is either 93 or 95 octane RON in their manuals, but you would have to check your owner's manual to be sure... (95 RON in the UK is about equal to 91 RON in the US (which is the regular 87 octane using the ((R+M)/2) method (which is what is usually posted on US pumps)).

- 4.6L Fuel Octane. Run the 87 octane fuel in your truck and you will keep your engine cleaner inside(valves, etc.)have easier starting on cold mornings and save some bucks at the gas pump. The engine does not need any higher octane to perform properly, it will run worse and get worse gas milage on the high octane stuff.

Octane 101: Autogas vs. avgas The wrong fuel octane used in your engine can mean the early demise of your engine and you, if you are not careful. Octane 101. The octane rating of gasoline refers to the fuel's anti-knock quality, Autogas octane is rated differently than that of avgas.Two CFR (Cooperative Fuel Research) knock-test engines, adopted by ASTM, are used to test automotive gasoline according to ASTM D 2699 and D2700 standards.eltex' Inc.'s portable octane analyzer, is battery-operated and uses near-infrared technology to provide an accurate fuel octane analysis in less than 45 seconds. More and more pilots are obtaining STCs for their aircraft to use autogas.

Paying a Premium for High Octane Gasoline? One state may require a minimum octane rating of 92 for all premium gasoline, while another may allow 90 octane to be called premium. To make sure you know what you're buying, check the octane rating on the yellow sticker on the gas pump.

How Gasoline Works The amount of compression is called the compression ratio of the engine. A typical engine might have a compression ratio of 8-to-1. (See How Car Engines Work for details.). The octane rating of gasoline tells you how much the fuel can be compressed before it spontaneously ignites. When gas ignites by compression rather than because of the spark from the spark plug, it causes knocking in the engine. Knocking can damage an engine, so it is not something you want to have happening. Lower-octane gas (like regular 87-octane gasoline) can handle the least amount of compression before igniting.

Octane rating The selection of octane ratings available at the pump can vary greatly from region to region. 1  Australia, regular unleaded fuel is 91 RON, premium unleaded with 95 RON is widely available, and 98 RON fuel is also reasonably common.

Butane & Propane Gas Propane (/ˈproʊpeɪn/) is a three-carbon alkane with the molecular formula C3H8, a gas, at standard temperature and pressure, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, it is commonly used as a fuel for engines, oxy-gas torches, portable stoves, and residential central heating. Propane is one of a group of liquefied petroleum gases (LP gases).

The Differences in Gasoline If you want to understand the important differences between these gasoline choices, read on. Octane is not a measurement of power. Octane ratings are a measurement of the fuel's ability to resist engine knocking or pinging. The knock results from uneven burning of the compressed fuel-air mixture.

Indy's Super Fuel The actual fuel used by the IRL is a blend of about 98 percent ethanol and 2 percent denaturant. The exact composition includes a small amount of high-octane racing fuel. The fuel for today's Indy cars has an octane rating of 113, compared with methanol's 107.

How adding ethanol can increase octane value in gasoline ? Gasoline is primarily composed of octane. With that out of the way: the octane rating of gasoline only has a tangential relationship to the chemical octane. The octane rating is a measure of the resistance of gasoline and other fuels to detonation (engine knocking) in spark-ignition internal combustion engines.It is so named because a fuel composed of 100% iso-octane has an octane rating of 100.uels which are less resistant to detonation have an octane rating lower than 100, fuels that are more resistant to detonation have octane ratings greater than 100. Since ethanol is less explosive and more resistant to detonation than iso-octane, it has an octane rating greater than 100.

- First, the octane rating for the avgas that you mentioned is much higher than used in general aviation for the most part, so my first question is who or what told you that? I really question the validity of the octane rating. General avgas has a 100LL rating....not enough for 12 to 1 race motors I might add.

Octane rating Octane rating or octane number is a standard measure of the performance of an engine or aviation fuel. The higher the octane number, the more compression the fuel can withstand before detonating (igniting). In broad terms, fuels with a higher octane rating are used in high performance gasoline engines that require higher compression ratios.
