best is when they switch to ethanol 1n my state.
1) it ate my fuel lines, they seriously turned to jelly and started to weep fuel through the surface.
2) it ate my accelerator pump diaphragm, i got a nice lake of fuel on my intake manifold.
3) engine PING like crazy.
4) MPG dropped in half
woopppy dooo. i know people going insane when the EPA said they wanted 15% of that garbage in the fuel.
10% screwed up everything they even warn you 10% ethanol is only good for engines designed after 2004, my 1995 mitsubishi suddenly the fuel pump stopped working the week they switched to 10%..... just awesome. i had to have a SPECIAL pump made for me.
