Put 5 gallons of water/antifreeze in my 2012 with a few gallons of C85 still in the tank. Started the car and it didn't run to well. I can't imagine why, guess they are not meant to run on that combo.
Pumped the gas out and replaced with VP C85 and drove the car 60 plus miles home.
What if any issues do you think I might experience going forward?

Put water/antifreeze where? If you mean in the tank by mistake that sucks. I'd imagine it'd take a few tanks to finally get out the water since I'm sure there is always some left when you pump it out. On the plus side it should mix with the ethanol and not float on top and then you get a layer of just water.

Holy Toledo.....if I'm reading that correctly.....I'd change the engine oil and fuel filter for sure! ASAP. Don't run it any more until you do.

Once you do that....start data logging and make sure pump and inj cycles are appropriate. No idea what coolant contamination would do to fuel pumps or injectors long term....but it can't be good.

If you dumped the water and ran fuel through it before any corrosion could take place, I wouldn’t sweat it.
Especially if you just ran it 60 miles and aren’t seeing any problems.

Thanks for the replies. Here is what we know as of today.
The main pump is toast, it didn't get the second pump because it comes on in boost and the car didn't see boost driving home.

I don't think there should be any corrosion xxxx because it was started then drained and E85 put right back in and driven for an hour. What I don't know yet because the pumps aren't here, is if the injectors were effected. Will have to wait and see.

I won't bore you with the details on how the mix go in the tank but just that we grabbed the wrong gas can.

It was the main pump. The second never came on with the mix of water/antifreeze. Fingers crossed for the injectors.
