Hi! My 2013 Honda Civic (92,000+ miles) is shuddering, bucking, upon LIGHT acceleration with ECON on or off and with A/C on or off.

My question is: I have been putting the 10% ethanol gas in it since i bought it new, can I all of a sudden start putting regular, high grade, unleaded NON Ethanol gas in it to see if that is my problem? I don't want to just start putting a different gas if it is going to ruin my gas tank.

 

You don't want to put 91 or 93 but try to find 87 without ethanol. Change your spark plugs if its never been done and do whatever other general maintenance you've been neglecting.

 

Thanks so much Chrisfrom1986. Mechanic said spark plugs look good, as do the coils.

change the oil every 3,000. Whatever is happening is not registering on the computer.
Doesn't do it for more than a minute, I guess. He said I accelerate from a STOP too lightly.

Will try the 87 octane without ethanol. Thanks again, much appreciated.
