Engine

E85 accidentally put it diesel fuel tank, advice?

1 1/2 gallons of E85 (Flex Fuel) was put in my diesel car. My roommate put in about 7 gallons of diesel to try to offset it. It Started up fine, drove 10 miles to my house and the engine sounded a little rough, but nothing major. The car is at about 4/10 full tank, should I fill it up with diesel frequently to balance it out? Or should I get it towed to a dealership or shop and get the fuel tank drained, fuel system flushed, and fuel filter replaced? Also, what would the cost of this being done put me back? One more thing to add, the car has an electric fuel pump, if needed to be replaced, whats the cost estimate for that? thank you.

If it is hard to start, you need to get that fuel mixture out. Just syphon out what you can, fill it with fresh diesel, put in a double dose of Power Service or Stanadyne and you should be fine. (You might want to hit it with a little 2-stroke oil, too.)
