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

[ghosthunter]

true. i used to fill up at shell stations almost all the time before because of the citibank rebate. now im worried about the corrosion thingy that my engine might have accumulated because of the e10.

E10 wont corrode your fuel tank that quickly unless your tankful of E10 is badly contaminated by water mixed in the gasoline. So unless the shell station you got your E10 gas from was recently flooded, I don't think a week's exposure to E10 would do that much problem.

i drained the rest of Petron's E10 yesterday, and have a tankful of XCS, cost me 800+, parang nag iba ang takbo, nawalan ng minor sa XCS ngayon, sa e10 naman nuon, parang sinisinok . did e10 had damaged grandpa's owner fuel lines already?

Check the carb jets for any signs of erosion at the tips.

you may need to adjust the idle screw and idle air screw.

Guys, is it okay if I switch to Petron XCS (non-e10) from Petron Extra Unleaded (e10) even if I haven't fully consumer the latter? Will it affect my engine?

Also, is it okay to fill up gas from different gas stations? Kunyari, Petron Extra Unleaded ako ngayon. Then pag pa-ubos na ang fuel, pakarga ako sa Shell ng unleaded then. Minsan kasi, wala yung favorite gas station mo when driving pag paubos na yung fuel mo.

Thanks in advance!

Just letting you know that Shell Unleaded is E10 gasoline. In fact, all shell gasoline products have E10 mixed into it already.

If you want gasoline without E10, try Petron's XCS.

Yup okay lang ito. Anyway pare-pareho naman yung unleaded dito na E10 na.

mga sirs ask ko lang what with the problem with e10 i havent heared na menasira sa E10 even E20, can any one enlighten me, thanks.

^since ethanol absorbs water so there would be a higher moisture content in your fuel system. In older vehicles, fuel lines could be corroded in the long term.

if that is the case then all caborator and mechanical fuel pump will have a problem tama ba ako.

[vernieg]

Ang pinaka problema is not the water absorbed by ethanol. Ethanol mismo ang problema since ito ang kakain sa soft metals parts (kung meron man) ng fuel lines. Sa carburetor, soft metals like brass (jets), zinc and aluminum ang mag corrode not by water but by ethanol. Nakita na namin kung gaano kalala ang corrosion na maidulot ng ethanol kahit less than 10% pa. Nangingitim ang carburetor jets until liit na ang dadaanan ng fuel dahil sa corrosion.

Ang contribution lang ng water sa problema ay kung water ang mahigop ng fuel pump at pag dating ng water sa carburetor ay more on water ang andun sa float bowl at lesser ang gasoline, papalya talaga ang makina or mag mimisfire since di mag combust ang water.

Ok lang kung may iba kang daanan ng water at gasoline, at 50:50 mix at sabay itong ma deliver through a carburetor, lalakas ang makina pero kung mauna ang water than gasoline, papalya talaga.

Some carburetors ay matagal or di masyado mamalayan ang problema in a shorter time dahil mas malaki ang butas na daanan ng fuel than carburetors found in other cars like sa Nissan LEC for example. However, ang pa minsan minsan na palyado na firing or ang misfiring effect dahil sa water content will be there from time to time and you will not like it to happen lalo na on heavy stop and go traffic.

if that is the case then all caborator and mechanical fuel pump will have a problem tama ba ako.

Now im starting to worry kasi im using E20 on our sedan, but it is a 2009 model maybe this is already a ethenol compatible but still i worry.

[kamotecueman]

mga tol
pwede ba ihalo ang xcs sa e10 na unleaded?
may 1/4 pa kasi akong unleaded from petron sa tank ko
balak ko i xcs na siya next week
ok lng ba yun??
need your replies po

[number001]

^pwedeng pwede naman.

[kamotecueman]

^pwedeng pwede naman.

rhanks for your response
pero pag tinuloytuloy ko na yung gamit ng xcs mawawala na rin yung e10??
tol,pag mas madami ba yung xcs na ilalagay ko mas mauna ba nyang susunugin ung e10 na stock sa tank ko?

[Bin Diesel]

for our guidance, maybe we can compile a list of gasoline blends that are ethanol free:

WITHOUT ethanol

- Petron Blaze and XCS (confirmed by Petron CS)

WITH 10% ethanol

- Petron Xtra Unleaded, Regular Unleaded
- Shell V-Power, Super Premium, Super Unleaded (in other words, all Shell gas blends have ethanol)
- Caltex Silver

pa-complete na lang pls. thanks.

Haay... di ko din alam before na lahat ng gas ng shell e e-10 na pala... last week bigla na lang nagluko sasakyan ko nagtagas ang fuel hose ko tapos bumigay ang fuel pump ko...

When the filter was checked grabe ang daming dumi, then i read in an internet article that ethanol blended gasolines can cause pump failure and degredation of fuel hoses and it can absorb water which may clog the filter and the injectors. Also because of it's a solvent (ethanol) users must change their filter from the standard 30 microns to 10 microns.

Grabe talaga... sana huwag mangyari sa inyo nangyari sa akin.

By the way I'm using a 1996 nissan sentra and according to the manual e-10 is compatible... pero the manufacturer is not sure of the long term effects to the engine.

[vernieg]

Similar thing nangyari sa 1999 Nissan Sentra LEC, buti nalang ok pa ang mechanical fuel pump, carburetor lang ang inayos namin at nag palit ako ng fuel filter. Pinalitan ko na rin ang orig na fuel hose directly connected sa output ng fuel pump dahil naninigas na at nag leak.

The following information from biofuelshub.com made me try using fuel with ethanol on a 1999 Nissan Sentra LEC for testing and it turns out hindi magkatugma ang results sa testing at sa information na binigay ng site na ito na compatible with fuel na may ethanol ang Nissan models released from 1995 and above. First week pa lang may symptoms na sa problema na maramdaman until we decided to check the carburetor which we found out na nag start na pala itong mag build up ng corrosion on its jets. We did checked the caburetor before implementing the test and all parts, including the jets, are clean.

It is very much possible the site above is funded by those ethanol producers in our country that they will do anything to encourage us to use fuel with ethanol kahit hindi ready ang majority ng cars dito to use fuel with ethanol.

These people will not pay you naman kung ma damage ang car from using fuel with their ethanol. This is not about caring for everyone, this is not about caring for the environment and this is not about caring for a cleaner air that they promote ethanol. Using the current blend of fuel with ethanol just that not fit the majority of our cars in this country. What we have in this country is lots of water where you can get hydrogen from it. Dapat yan ang pinopromote nila at ginawan ng business plan at hindi ang ethanol na only a few ang makinabang at majority ang naiipit.

Just use up the tank of Shell Premium down to near to empty as you would dare and fill up with Petron XCS on your next full tank.

You don't have to mix gasoline types to minimize the effects of E10.

sir ghosthunter

ok lng po ba kung ang laman ng tank ko ay mga 1/4 na e10 tapos lalagyan ko ng xcs? wala na ba akong mga papalitan na kung anu ano?

The problem is the E10 content will contaminate the XCS you mix with it. Ethanol absorbs water and even small percentage of ethanol will go a long way. If you don't want to dump the existing E10 mixed gasoline, just use it up quickly and try to run as close to empty as you dare so the amount of ethanol mixed into your XCS will be as small as possible.
