Hi,
My wife accidentally fuelled up my Civic 2016 with E-85 fuel. The dashboard started showing various errors:
1. Emissions System Problem
2. Hill Start Assist Problem
3. VSA problem
4. EPS problem
5. Brake hold system problem
6. Brake system problem

Took it to the Honda service center. They mentioned $700 for draining the fuel and induction service.
Is this necessary?

Some of the local auto care centers mentioned to go ahead and add normal gas to reduce the ethanol content.
Will this work?

Any suggestions are welcome.

Go to Harbor Freight and get one or two 5-gal gas cans and a liquid transfer pump and siphon out 5 to 8 gals. After that, fuel up the tank (Civic) with regular gas. If you choose to only siphon out 5 gals, the car will run okay but maybe a little lean until the next fill up (regular gas), hence my suggestion to buy two 5-gal gas cans to siphon out 8 gals. Car will run normally with up to 4 gals of e85 and 8 gals of regular gas mixture.

What do you do with the siphoned out alcohol? You don't drink it. Put it back into the car 2 gals at a time after each fuel up and driving for 70 miles.

Thank you for the reply.
So would the warnings automatically stop after the ethanol level goes low?
Or do I need to manually reset it from somewhere?

Yes, they should go away after fueling up with normal gas. May need to drive it a few miles after normal gas fill up before returning to normal.

I was also going to suggest a siphon. Not sure who has siphoned from these new civics yet but the capless system might be a bit of a problem. Maybe put the emergency funnel in, and then siphon through that? I'm guessing it's sort of a double flap system.

All of the above. But maybe get a really soft and flexible length of tubing from somewhere and gently do as advised above. Damaging anything with the EVAP system can be just as costly.

This worked.
I added premium fuel in my half tank and let it run a bit.
All the warnings went away today afternoon.
Thank you for all the help :)

I thought the gas inlet hose has an anti siphon flap down in it. Where would be the best place to siphon? The fuel rail under the hood? Would I have to power the fuel pump? Thanks.

Maybe use the funnel adapter and a lots of trial and error with a soft hose.
