I do recall one neighbour, irritated at the open pipes on his neighbour's bike, who was found to have been topping up that bike's fuel tank with assorted soft drinks over an extended time. The rider couldn't figure out why his fuel economy was slightly better even though the bike ran like crap cola.
just called esso today, supreme is 0% ethanol, mid grade is 5% and low grade (87 oct) is 10% ethanol.
Wrong! The higher octane actually burns (not explodes) slower than low octane which is the main reason it is used in higher compression engines, to avoid detonation. I'm not advocating ethanol but you could make less power using a higher octane if your engine doesn't require it. The oil companies market fuel this way to mislead the public into thinking more expensive is better.why so many stupid answers.
ethanol is bad, SHELL 91 CDN TIRE 91 no ethanol. go with the highest you can afford, also depends on your riding habits. the higher the octane the higher the temp at which it explodes and more compact. lower octane will explode at a lower temp range and be less compact which translates into a weaker explosion. manufacturer gives the lowest rating based on engine compression.
just called esso today, supreme is 0% ethanol, mid grade is 5% and low grade (87 oct) is 10% ethanol. and according to wikipedia, ethanol-free gas gets 3% better fuel economy than 10% ethanol. ALSO, if your bike uses a carburetor instead of fuel injection, ethanol is harmful to your carbs and can clog the jet pilots (especially on my lean-running ninja 250r), so i always use ethanol-free gas.
As a couple of others have stated , fuel without ethanol is best for bikes (especially those with carbs , and when stored for extended periods) , so I use SHELL 91 or Petrocan 91 even though one of my bikes doesn't need the higher octane . More expensive but worth it .
Good afternoon D. J.
Thank you for contacting Petro-Canada Customer Service online.
In Southern Ontario, from Sarnia to Bellville, up to Port Perry – Gravenhurst, Petro-Canada branded stations, without Ultra 94, the RegularClean 87 and 89 will contain ethanol while SuperClean 91 gasoline contains no ethanol.
At Petro-Canada branded stations with Ultra 94 available, all grades of gasoline will contain ethanol. The Ethanol content in the gasoline is 10% maximum.
All current Sunoco branded stations in Ontario sell gasoline containing ethanol. The Ethanol content in the gasoline is 10% maximum.
At sites where ethanol fuel is sold, there is a yellow label affixed to the pump on the upper steel cladding above the pump top or on the pump itself (at older installations) warning “Gasoline may contain up to 10% Ethanol”.
Ethanol Blended Gasoline available in Ontario, supplied by all companies, contains a maximum of 10% ethanol. Only grade of gasoline that will not contain ethanol is Premium Octane 91 gasoline, as long as the site is not selling a 94 Octane grade. This level of ethanol is the standard addition rate throughout the petroleum industry. To avoid purchasing gasoline without 10% ethanol, one would have to purchase RegularClean 89 (contains 5% ethanol) or Super Clean 91 (contains 0% ethanol) at a Petro-Canada station that does not sell Ultra 94.
However, as more environmental regulations come into effect, such as this years Canadian Government’s Renewable Fuel Strategy, the increased use of biofuels, such as ethanol, is being mandated in the blending of finished gasoline.
