The European (and many countries) Octane rating system as listed on the pumps is the RON and is 4-5 points higher than in Canada or US. Here the pump number is RON+MON/2 and 87 here is equivalent to a 91 or 92 in Europe. However many pumps in Europe the "regular" is a 95 RON so closer to our 89.Most of it yes but starting to add it in. Shell V power in Switzerland is 100 octane..
Do you know which companies have no ethanol in their gas i have an oe Shadow Ace vt750cddAs stated above, ethanol has an "octane rating " of about 115. Octane rating is related to how fast fuel burns in the combustion chamber, with higher ratings = slower burn, making the use of more compression and/or ignition advance possible to improve power without detonation or preignition. Ethanol also has more oxygen in it than gasoline which helps achieve a more complete combustion. Incomplete combustion yields carbon monoxide ( CO ) which is poisonous, complete combustion yields carbon dioxide ( CO2 ). That's why the pure 91 octane gas is also called " non-oxy ). Ethanol also lowers combustion temperature, resulting in less NOx emissions too. Ethanol also has less energy density than gasoline, so you get a little less power from it than the same amount of pure gasoline. My Shadow gets a steady diet of 91 non-oxy, mainly because I feel it runs a little better on it, and I don't have to worry about the residue that ethanol leaves in my carbs. Ethanol also absorbs water, which can get left behind and cause corrosion when the ethanol evaporates.
One local Shell station and one local Circle K formerly known as Flash Foods offer ethanol free aka marine gasoline. Do a google search on marine or ethanol free gasoline near you.Do you know which companies have no ethanol in their gas i have an oe Shadow Ace vt750cdd
The higher the octane, the more resistant the air/fuel mix is to igniting from a hot surface, such as the piston head or the exhaust valve port. Pinging has nothing to do with how fast the a/f mix combusts. It happens when the a/f mix enters the piston chamber and ignites in one area from a hot surface, and then ignites from the spark plug. Those two combustion 'waves' hit each other and cause the piston to rattle around, causing the pinging sound.Octane S L O W S combustion and so if your motor is pinging, the octane content of the fuel should be increased. And when I added Shell Premium to my gasoline, my Dodge 318 motor ran smoother and started more easily in the morning.
an alternative octane booster is Tolulene, : Toluene - additive for racing fuels, fuel octane boosterI used to mix Sunoco 260 and toluene
0% Ethanol is desirable for over-winter or other long term storage, where the gumming effect of ethanol can cause problems.I have been running the ethanol so long I don't know why I would spend double the price and the inconvenience of going to get it.
