E10 gasoline on carb engines [MERGED THREADS]

**gado** · March 25th, 2008 06:07 AM

can I use Shell E10 gas for a carburetted engine? The sign at Shell stations say E10 is "normally" used for fuel injected engines? Would I need to adjust timing or carb settings?

nope, you can't use e10 for carb engines.

take note of the following paragraphs:

E10 is the most commonly sold ethanol-blended gasoline in the United States. It contains 10-percent ethanol and 90-percent gasoline. Most automobile manufacturers warranty their vehicles to work with E10. At 10 percent, the ethanol generally does not cause corrosion or starting problems. But at higher concentrations, the fuel tank, pump, lines and fuel delivery system--whether a carb or fuel injection--must be designed differently. The same is true for other engines, including outdoor power equipment, though a slight carburetor adjustment may be needed.

Cguro patingnan mo sa experto sabi kc ng shell ok lang kaso di naman nila sasagutin kung may masamang mangyari sa makina, ang sa akin kahit 98'model matic nga lang kaya umobra 4months na ang gamit ko sa E10 okey naman sya walag usok at hindi maamoy ang buga ng tambutso.

AFAIK (and accdg to the article posted previously), 10% ethanol is the most that carb engines can survive without any problems. above 10%, there will be problems because:

1. alcohol can dissolve/remove gum formations in the fuel system which asounds good at initial look until large particles of gum blocks your fuel line or carbs.

2. stock rubber fittings (oil seals etc) are not made for ethanol and may result to leaks.

3. and if i am not mistaken, ethanol is corrosive as compared to gasoline. so fuel lines which can corrode can cause problems with higher concentrations of ethanol in fuel.

AFAIK, E10 gasoline will only work with efi engines...

may nagsabi sakin dati totope daw yung oto na carb kung lagyan ng e10. well thats what ive heard lang naman. not sure if is true.

but on the other side, sabi ng honda before sa press release nila involving e10... all models from 1990 up can run with the e10 gasoline. so meaning yung mga naunang civic na carb can run on those...

hmmm... confusing nga talaga.

- definitely not true.. my car is carbed. pero mas gumanda pa nga yung takbo when i used E10. nung regular unleaded gamit ko, may minimal knocks, pero ngayon nawala.....
