E10 Ethanol, bad for your engine & economy? [MERGED]

this the site for Philippine Daily Inquirer regarding their Sept 8 2009 issue regarding ETHANOL. http://www.pressdisplay.com/pressdisplay/viewer.aspx

click the calendar and select sept 8. then on right side click page A4.

for other infos that would explain further for ETHANOL check out this site so you would know is ethanol really has either PLUSES or MINUSES. http://en.wikipedia.org/wiki/Ethanol

for the summary, well ethanol is primarily extracted (and process) from sugar cane. it is a colorless waterless (liquid) alcohol with a chemical equation C2H5-OH. usually use for fuel for burners in chemistry laboratory and the well know spirited alcoholic beverages.

when use as fuel or burned, it attracts 3 compound of oxygen2, it produces 2 compound of cabon dioxide and 3 compound of water. C2H5-OH + (3)O2 = (2) CO2 + (3) H2O. simple chemical reaction (chem 101).

ethanol is highly volatile, meaning when expose to air or a minimal amount of heat, it evaporates quickly.

these explain why the E10 gasoline sold today said petron can damage engines. petron said it is highly corrosive and harfull to fuel pumps, carburetors, fuel lines injectors and everything in the fuel system. though gasoline stations recommend it to fuel injected engines only and other car manufacturer also claim that some of their vehicles are E10 ready already.

if you would notice and analyze clearly Ethanol itself is not the harmful substance in the E10. even if you would submerge a methal or the fuel pump for example in a pure ethanol. nothing would happen.

its ethanol's property. it is volatile!E10 inside the fuel tank evaporates, water vapor is form, so when you park your vehicle and the whole night pass, the next morning when you travel the water vapor on the tank mixed with the fuel. so the fuel is contaminated that causes the reaction and form the corrosive compounds that harms fuel system components.

also during combustion, water is form when ethanol is burned. meaning, again after a whole night has passed, the next morning. water vapor accumulates in the combustion chamber and exhaust port and in exhaust valves. though this factors quickly eliminated when the engine runs and heat up.

E10 fuel is 90 percent gasoline blended with 10 percent ethanol. I'm sure everybody knows that. and it is given a purple coloring to distinguish it from unleaded gasoline which is green, premium is red or dark red, regular gasoline light red, orange. V power (shell) and Blaze (petron) is unleaded and colored blue. if all this kind of gasoline is blended with ethanol, they should be colored purple also!!! but they are not.

also, base on the data on this site http://en.wikipedia.org/wiki/Ethanol, E10 has a maximum of 93-94 percent of OCTANE rating with lower energy you can squish compare to pure gasoline. so if V-power has and blaze has ethanol blended to it, it would not have an 95 and 96 percent octane rating (respectively).

on the other hand, compare to gasoline fuel when burned. E10 produces less harmful compounds and substances in the air. a pure ethanol would yields many of the products of incomplete combustion produced by gasoline.

since E10 produces less power than pure gasoline, carburetors needs to be re-jetted, so it permits larger volume of fuel to mix with the air entering combustion chamber. this is not a problem with EFI engines since, various sensors monitors exhaust gas, intake air, injector pulse and others to compensate the fuel mixture for combustion. meaning it needs more E10 fuel two produce the power that pure gasoline can.

E10 is only cheap because of its price, but for the fuel consumption better check your chem 101 and math 101.

Correction. E10 gasoline is only cheap because of the price subsidy the Philippines government imposes on it.

The RON value of E10 blended fuel will depend on the RON of the base gasoline. 10% ethanol added to gasoline typically increases the fuel blend's octane 2-3 points.

That's how you get 97 or so octane from Blaze with 10% ethanol added to it.

di nga nagkakalayo ang price tag ng e10 sa non-e10 blended gasoline, ex. is Premium E10 and XCS ng Petron, P0.50-P0.85 lang difference nila, compare nung Premium Unleaded (pure gas), P0.50 lang din difference? how come na cheaper ang E10 vs Pure Gasoline?

and ito pa, shell all variants e10 blended? bakit same lang price ng XCS sa Premium, and VPower vs Blaze? shell's gasoline are ethanol blended and Petron's XCS and Blaze are pure gasoline.

Do the Math? Walang matinong benefits sa E10! Aint that cheap but cause to cost a lot!

Iboycot na yan!

well we all know who pushed the biofuels act of 2006, wala pa silang study na maayos pinilit agad sa mamamayang Pilipino

Boycott E10 gasoline! ... Use Auto-LPG!

iboycot na ang E10!

base on this sites, shell V power fuels usually has a RON of 95 and above octane rating. it did not state that to get a higher rating of octane they mixed a 10% ethanol. like the 97 octane rating that is sold today by shell. http://en.wikipedia.org/wiki/Octane_rating, http://en.wikipedia.org/wiki/Shell_V-Power.

and read this http://www.shell.com/static/ph-en/do..._holthusen.pdf then tell if V power has ethanol.
