Yes, Sunoco gasoline typically contains ethanol as it is commonly blended with gasoline to meet environmental regulations and increase octane ratings. It is important to check the pump or contact Sunoco directly for specific information on the ethanol content in their gasoline.
Octane is a measurement of the combustion process. Most commonly you will see "85 87 91" octane ratings on your average gasoline pump, this of course indicates the amount of octane that, that specific product contains. The only purpose of octane is to resist detonation. What this means is that a higher octane gasoline is actually more stable than a lower rated fuel. When any kind of fuel is subject to high pressure and high heat (just like you'll find on the compression stroke of an average automobile) it becomes unstable and in some cases will spontaneously combust without an ignition source, this is called "detonation" which will make your engine sound like it's "knocking". Vehicles requiring a high octane fuel most often have engines with higher compression ratios which of course cause higher heat and higher pressures. Most common vehicles only require an octane rating of 85, octane ratings of 87 and 91 won't make your car run any better.
NO,,use Octane booster instead,,adding a lot alcohol will clean out the fuel system so much that might plug up the filter and pump.
Pump gasoline is a blend of several hydrocarbons, obtained in the refining of crude oil. A few of these are nonane, heptane, butane, octane, etc. Pure octane is the slowest burning of those used and the least likely to "explode" or detonate in the engine when ignited. Detonation causes mechanical damage and lowers fuel economy. The octane rating of any pump grade of gasoline is comapared to pure octane. 87 octane fuel is lower than 93 octane and will burn faster (not good). 100 octane is equivalent to pure octane in burn rate. Pure octane would be too expensive to use, so a blend of several hydrocarbons is used for various reasons. Hydrogen, I would think might burn way too fast in an unmodified gas engine, but have never read about any studies on this.
you can use any of the three gasoline's available at the pump, it doesnt matter. ========================================================= I was looking at the 2002 Lincoln Continental Owner Guide and it shows to use " premium " unleaded , 91 octane
According to the 2001 Mustang Owner's Guide: Use regular unleaded gasoline with pump octane rating of 87. Premium unleaded gasoline in NOT recommended (particularly in the United States).
Octane, technically speaking, is the number of octane atoms in a molecule of gasoline. Gasoline ( we are leaving out the ethanol component's effect ) is a mixture of several hydrocarbons including heptane, benzine, and others. The number of octane atoms ( or its equivalent in the case of ethanol blends ) in the gasoline give it the number you see at the pump. It is a measure of gasoline's ease or resistance to burning when air and heat are present. High performance engines use high octane gasoline because they can compress the fuel more before igniting the mixture creating more power; if lower octane fuel is used, the knock sensors detect this and retard the timing to avoid engine damage which is why your mileage drops. Conversely, fuel mileage does not increase by burning a higher octane than needed; the higher octane's ability to resist ignition works against you and incomplete fuel combustion can result. The unburned fuel is dumped into the catalytic converters where it is burned, fouls the catalyst, and can cause failure of the converters.
I have a 2002 Acura RL 3.5. The owner's manual states, "Your Acura is designed to operate on premium unleaded gasoline with a pump octane number of 91 or higher...we recommend gasolines containing detergent additives that help prevent fuel system and engine deposits." That being said, I ran 87 octane during the last gas crunch and all was fine.

A failed fuel pump can cause gasoline to get into the oil.A failed fuel pump can cause gasoline to get into the oil.
Indiana invented the first gasoline pump submitted by dominique
It is the nozzle you insert into your fuel tank filler neck to pump gasoline into your vehicle.
